End bearing piles (also known as point-bearing piles) are used to distribute large foundational loads from the topsoil, which has a low bearing capacity, to the rock beneath, which has a much higher bearing capacity. Loads can also be transferred to strong stratum such as dense sand and gravel instead of rock. By passing through weak topsoil to rest on the stronger soil below, end bearing piles behave much a like a column. End bearing piles are essential foundational elements for large structures like factories, stadiums and bridges. Without end bearing piles, topsoil would not be able to support these buildings.In order to achieve their full benefit, end bearing piles must pierce the firm strata (eg: the rock) by at least three times the diameter of the pile. When designing end bearing piles, buckling failure is not considered unless parts of the pile will pass through water or air.

What Are End Bearing Piles Made Of?

End bearing piles can be made of wood, concrete or steel.Traditionally, wood piles were used to support buildings in areas with weak soil. The city of Venice is famous for being built on wooden piles over the sea. Today, wood piles are used to make jetties. However, the pile length is limited to the size of the tree from which the wood was cut.End bearing piles made of concrete and steel can be prefabricated, meaning they’re created ahead of time and transferred to the construction site (as opposed to casting the piles on site). Both concrete and steel end bearing piles can support heavy loads. Concrete piling works best in areas with corrosive soil.Steel end bearing piles are favored for many reasons. Because the steel piling can be tweaked to exact load specifications, costs can be reduced. Steel piles are relatively easy to build, and they’re also easy to replace after construction is complete, so their maintenance and replacement costs are some of the lowest. For large structures such as buildings and bridges where a deep foundation is necessary, steel end bearing pile is an excellent choice.

What Are the Advantages of End Bearing Piles?

End bearing piles come with a number of advantages when compared to other types of piling, like friction piles or floating piles.

• End bearing piles don’t experience as much settling as other types of piles, which is why the largest multistory buildings are most commonly constructed atop end bearing piles. Furthermore, since end bearing pile rests on firm stratum far beneath the topsoil, it’s considered the strongest type of loadbearing option available.
• End bearing piles can be precast, meaning they’re constructed offsite and transferred to the construction location. Piles can be precast to any prespecified length, shape or size, which cuts onsite construction time. Similarly, the cost of construction can be optimized since each pile’s length can be specified based on the depth of the deep stratum on which the pile will rest.
• End pile lengths can be easily calculated based on the bedrock depth, which is gathered from soil exploration borehole records.
• Unlike some types of piling, end bearing piles will not buckle in weak soil.

What Are the Disadvantages of End Bearing Piles?

End bearing piles come with two main disadvantages:

• In order to install end bearing piles, heavy equipment is required. In addition to the added costs, this means that worker specialization will be necessary in order to install the piles.
• Due to the high friction around the piling, the soil that surrounds the pile may stick to the surface of the pile, which decreases its effectiveness.

What Are Common End Bearing Piles Sizes?

Common wide end bearing pile sizes include large beams, which can include:

• W21: W21x44, W21x50, W21x57, W21x58, W21x55, W21x62, W21x68, W21x73, W21x83, W21x93, W21x101, W21x111, W21x122, W21x132, W21x147, W21x166, W21x182, W21x201, W21x223, W21x248, W21x275

Friction piles are a type of underground piling system used to create a strong foundation for large, heavy structures such as stadiums, bridges and roads that could not otherwise be supported by the topsoil.

How Does Piling Work?

Piling works by transferring a structure’s weight from the loose topsoil to the stronger soil or rock below. There are two main types of foundation pilings: end bearing piles and friction piles.End bearing pilesWith end bearing piles, the bottom end of the pile rests on an underground layer of strong soil or rock. The end of the pile presses against this dense layer to keep the structure from shifting. Furthermore, the load of the aboveground building is transferred from the weak topsoil (which could not support its weight) through the pile, and onto the stronger stratum below.Friction pilesFriction piles work more like a wedge in the soil. These piles, also called floating piles, earn most of their bearing capacity by shear stresses along the sides of the pile, and they are best used in instances where the hard underlayers of soil are too deep to efficiently reach. Friction piles transmit the load from the loose topsoil above to the soil below by adhesion or friction between the surface of the pile and the soil. In other words, the friction of the soil around the pile is what holds the steel pile in place.

What Is Friction Pile Made Of?

Friction piles are made of long, slender elements, much like columns. They are typically crafted from steel or reinforced concrete, though they can also be made of timber. The piling extends below a structure by at depth that is at least three times the structure’s width.

What Sizes Do Friction Piles Come In?

Friction piles are often made of H-pile and wide flange beams, which are two of several different types of piling options. H-piles are as wide as they are deep and have the same thickness in the flange and web. When compared to standard beams, H-pile beams provides better weight distribution over a wider area. Because of this, H-piles are an excellent choice for friction piling since they can support larger and heavier structures; each pile can withstand loads of up to 1,000 tons.Common H-pile sizes include:

• HP8: HP8x36
• HP10: HP10x42, HP10x57
• HP12: HP12x53, HP12x63, HP12x74, HP12x84, HP12x89, HP12x102, HP12x117
• HP14: HP14x73, HP14x89, HP14x102, HP14x117

There are two major types of formwork: conventional and engineered. Conventional concrete formwork is made of timber, and engineered concrete formwork is made of steel or aluminum. Engineered concrete formwork can also sometimes be made of plastic, but that’s less common. Conventional forms are usually built on-site, while engineered formwork is prefabricated, or built elsewhere and then transported to a job site. Conventional formwork usually costs less upfront, but there are numerous benefits to the use of engineered formwork, particularly for large, wide-scale construction projects. Below are seven of the many benefits associated with using this kind of formwork:1. Engineered formwork is more rigid and durable.It’s not likely to warp due to changes in environment and temperature like wood, and it won’t rot like timber. This means you can trust that it will stay in place as needed while concrete is being poured and sets. It also means that you won’t have to worry about weather conditions affecting its performance.2. It can be used an infinite number of times.Thanks to its durability, engineered concrete formwork can be used over and over, up to around 2,000 or 3,000 times. Once concrete sets, it can be removed and used for another facet of the same project, repurposed for a new project, or sold. Timber formwork can only be re-used a few times at most before losing its viability.3. It can be resold for a high value.Steel and aluminum concrete formwork retain their value quite well, and selling them once you don’t need them anymore is an excellent financial decision. The knowledge that you can resell it after a project is complete may alleviate some of the concerns you could have about the upfront cost. Here at Eiffel Trading, we consistently get inquiries from contractors in need of used concrete formwork. There is a great resell market for all types of engineered concrete formwork!4. Purchasing it used can save you.On the other hand, buyers looking to save some money on formwork that’s in great shape will find that there are numerous affordable options of engineered formwork. And since it is capable of being used and re-used so many times, there are countless shapes, sizes, and configurations of used engineered formwork on the market to suit your project.5. It speeds up construction.Engineered formwork is designed for maximum efficiency, and since it’s not built on-site, it’s ready to go as soon as it arrives to a project area. Once it’s set up in place (pinned, screwed, or clipped), the process of using it is quite simple and easy. Although the upfront costs of conventional formwork may be a little less, time is money!6. It’s fire-proof.This is a big plus if formwork needs to be left out unattended for any period of time while concrete is setting or before/after a project begins. You won’t have to worry about any fire hazards.7. It’s safer.Because it’s rigid, durable, and stays in place better and because it often comes with built-in safety features, engineered formwork can reduce injuries and ultimately worker’s comp claims.Whether engineered forms are a better choice than conventional forms will ultimately depend on the needs of your project, but there are certainly a lot of advantages to engineered formwork in general. Looking into used engineered concrete forms may be a great idea if you’re on the fence about investing in conventional or engineered. It could ultimately be a more worthwhile investment that offers greater returns in the long run.

Combi-walls are a type of piling used in heavy marine construction and deep foundation applications that require high loadbearing capacity. When a regular sheet pile wall won’t provide enough support, a combi-wall system can be used instead. Combi-walls can be temporary or permanent.

How are Combi-Walls Installed?

Combi-walls are created using a combination of steel beams and sheet pile. The beams create the wall’s structure, while the sheet pile fills in the spaces between the beams to connect the wall and make it continuous. During installation, the beams are embedded into the ground at an angle that is perfectly straight and vertical, which guarantees that the beams are parallel to each other. This ensures that the wall retains its integrity.Combi-wall steel beams are installed as bored pile, which can be backfilled with concrete and reinforcing steel if required. A vibratory hammer is then used to install sheet pile into the spaces between the beams. Finally, the sheet pile is aligned and welded to the beams at interlocking points.If the combi-wall is meant to be temporary, the elements can be deconstructed and reused later when the wall is no longer needed.

Why Is Steel Beam Used to Construct Combi-Walls?

Combi-walls are constructed using steel beam for many reasons. Steel will bend under pressure rather than break, creating a more reliable wall that’s unlikely to crack or leak. Furthermore, steel can withstand vibrations, shock and high pressure, making it an excellent choice for structural support applications. Steel is stronger than most other types of metal and can be made larger or thinner without compromising its durability. In combi-wall construction, this durability creates a significant advantage.Unlike other materials, steel beam is rust-resistant and long lasting, since it’s resistant to many chemical reactions that cause corrosion. Particularly in the instance of permanent combi-walls, steel beam is a low maintenance choice that will last for years without the need for repairs or replacement.Steel beam is customizable and easy to install. The metal can be cut to any height or width, and it can be modified on site as needed. The versatility of steel makes it a good option for more complex projects.

What are Combi-Wall Application?

Combi-walls are an alternative to secant or sheet pile walls. They are often seen in heavy marine construction and deep foundation projects where the piling wall must have a high bearing capacity. Some common combi-wall applications include retaining wall structures, building foundations, wharves, piers, roadway structures, railway structures, bridges, dams, lake filling and port expansion.

What are the Advantages of Combi-Walls?

Combi-walls come with a number of advantages. They are a cost-effective shoring alternative to the secant wall, making them a more economical option. They also have significantly more load bearing capacity than a sheet pile wall, meaning they can be used for larger projects.

What are the Common Sizes of Combi-Wall Steel Beams?

Combi-walls are created with both wide flange and H-pile beams, and come in sizes large and small. Some examples of common combi-wall steel beam sizes include:W8: W8x18, W8x21, W8x24, W8x28, W8x31, W8x35, W8x40, W8x48, W8x58, W8x67W10: W10x22, W10x26, W10x30, W10x33, W10x39, W10x45, W10x49, W10x54, W10x60, W10x68, W10x77, W10x88, W10x100, W10x112W12: W12x26, W12x30, W12x35, W12x40, W12x45, W12x50, W12x53, W12x58 ,W12x65, W12x72, W12x79, W12x87, W12x96, W12x106, W26x120, W12x136, W12x152, W12x170, W12x190, W12x210, W12x230, W12x252W14: W14x22, W14x26, W14x30, W14x34, W14x38, W14x43, W14x48, W14x53, W14x61, W14x68, W14x74, W14x82, W14x90, W14x99, W14x109, W14x120, W14x132, W14x145, W14x159, W14x176, W14x193, W14x211, W14x233, W14x257, W14x283W16: W16x26, W16x31, W16x36, W16x40, W16x45, W16x50, W16x57, W16x67, W16x77, W16x89, W16x100W18: W18x35, W18x40, W18x46, W18x50, W18x55, W18x60, W18x65, W18x71, W18x76, W18x86, W18x97, W18x106, W18x119, W18x130, W18x143, W18x158, W18x175, W18x192, W18x211, W18x234W21: W21x44, W21x50, W21x57, W21x58, W21x55, W21x62, W21x68, W21x73, W21x83, W21x93, W21x101, W21x111, W21x122, W21x132, W21x147, W21x166, W21x182, W21x201, W21x223, W21x248, W21x275W24: W24x55, W24x62, W24x68, W24x76, W24x84, W24x94, W24x103, W24x204, W24x117, W24x131, W24x146, W24x162, W24x176, W24x192, W24x207, W24x229W27: W27x84, W27x94, W27x102, W27x114, W27x129, W27x146, W27x161, W27x178, W27x194W30: W30x90, W30x99, W30x108, W30x116, W30x124, W30x132, W30x148W33: W33x118, W33x130, W33x141, W33x152, W33x169W36: W36x135, W36x150, W36x160, W36x170, W36x182, W36x194, W36x210, W36x232, W36x256HP8: HP8x36HP10: HP10x42, HP10x57HP12: HP12x53, HP12x63, HP12x74, HP12x84, HP12x89, HP12x102, HP12x117HP14: HP14x73, HP14x89, HP14x102, HP14x117HP16: HP16x88, HP16x101, HP16x121, HP16x141, HP16x162, HP16x183

Soldier piles are a type of earth retention system commonly used in the foundation building process. They are also used for slope stabilization and remediation, and are favored due to their efficiency and cost effectiveness.

How Do Soldier Piles Work?

Soldier piles are used to create a strong foundation for heavy structures such as buildings, bridges and roads. The piles are commonly made of steel that’s driven into the ground to help distribute the weight of the structure from the loose topsoil down to the rock below. Soldier piles can also be used to create retaining wall systems for temporary projects, such as excavation during the construction phases.To install solider pile, the pile is forced into the ground. This can be done one of two ways, either by driving the piles or drilling the piles. Piles can be driven into the ground using a large impact hammer. Driving the piles is favored over drilling in situations where the soil is loose, since driving the piles into the ground compresses the surrounding soil and therefore causes greater friction. Steel piling can also be drilled into the ground using rotary boring equipment. Rotary boring is commonly used to install large diameter piles, and also when piles need to be installed in especially hard ground.When installing soldier pile, certain requirements must be met to ensure strength and effectiveness. Though soldier piles are often made of steel, they can also be made of precast concrete, micropiles, and conventional pipe sections. Piles are installed vertically and are spaced between six and 12 feet apart from each other. This system is designed to limit the movement of the soil, which allows for increased stability. If further stability is required, tiebacks can be drilled into the retained material.

Benefits of Soldier Piles

Soldier piles include many advantages. They’re cheaper to than other retaining wall system. Installation can be done quickly and with relatively less effort. The piles are highly customizable, and their materials are versatile.Versatility is valuable in a retaining wall system, since changes must sometimes be made on site. Furthermore, the simplicity of the soldier pile design means that advanced construction techniques aren’t required for installation. (It should be noted, however, that complex deep systems in urban environments will require more expertise and experience).

Disadvantages of Soldier Piles

Though soldier piles come with many advantages, there are disadvantages as well. Soldier piles are often used for temporary construction and are not always the best option for long-term applications. Improper backfilling can result in ground loss that cause surface settlements. Finally, soldier piles are not ideal in areas with a high-water table.

Common Sizes of Soldier Pile

Soldier piles in both wide flange and H-pile varieties. Some common sizes include:W8: W8x18, W8x21, W8x24, W8x28, W8x31, W8x35, W8x40, W8x48, W8x58, W8x67W10: W10x22, W10x26, W10x30, W10x33, W10x39, W10x45, W10x49, W10x54, W10x60, W10x68, W10x77, W10x88, W10x100, W10x112W12: W12x26, W12x30, W12x35, W12x40, W12x45, W12x50, W12x53, W12x58, W12x65, W12x72, W12x79, W12x87, W12x96, W12x106, W26x120, W12x136, W12x152, W12x170, W12x190, W12x210, W12x230, W12x252W14: W14x22, W14x26, W14x30, W14x34, W14x38, W14x43, W14x48, W14x53, W14x61, W14x68, W14x74, W14x82, W14x90, W14x99, W14x109, W14x120, W14x132, W14x145, W14x159, W14x176, W14x193, W14x211, W14x233, W14x257, W14x283W16: W16x26, W16x31, W16x36, W16x40, W16x45, W16x50, W16x57, W16x67, W16x77, W16x89, W16x100W18: W18x35, W18x40, W18x46, W18x50, W18x55, W18x60, W18x65, W18x71, W18x76, W18x86, W18x97, W18x106, W18x119, W18x130, W18x143, W18x158, W18x175, W18x192, W18x211, W18x234HP8: HP8x36HP10: HP10x42, HP10x57HP12: HP12x53, HP12x63, HP12x74, HP12x84, HP12x89, HP12x102, HP12x117HP14: HP14x73, HP14x89, HP14x102, HP14x117HP16: HP16x88, HP16x101, HP16x121, HP16x141, HP16x162, HP16x183

Waler beams, also referred to as “walers,” are horizontal beams that are bolted to a larger upright structure, such as a dock, in order to help support it. They can be placed at different heights or angles along a structure in order to bolster it most efficiently, and may be constructed from various materials such as steel, wood and composites. Retaining walls and docks often require the use of walers.

How Do Walers Beams Work?

Waler beams distribute weight over a wall or dock, ensuring that the pressure is dispersed along the entire length of the structure. Without waler beams, sections of walls or docks that are under stress may shift or break. By slanting waler beams on a diagonal, the beams can be used for further increase a structure’s weightbearing capacity.When used on retaining walls and docks, waler beams can also act as a buffer from ships that might bump against them, and are therefore important to maintaining the security of those structures and the safety of the people around them. When a ship bumps against a retaining wall secured with a waler, the beam absorbs the force and spreads it out from the point of impact, ensuring that the wall doesn’t break upon contact.

Waler Beams Made of Steel

Steel is the most common material used to make heavy duty waler beams. Steel has good bending stiffness, meaning that it will bow rather than break in extreme conditions and is therefore less likely to crack than other materials. The strength and flexibility of steel makes it a great option for waler beams since it can withstand vibrations, shock and high pressure.

Self-climbing concrete formwork is a type of formwork that is used to create tall concrete structures like core lifts and shear walls. It typically begins on one level and moves up to higher levels as concrete is poured into the molding to achieve the desired shape at each step of the process. Some examples of self-climbing formwork include jump system formwork and slipform. These types of formwork often climb hydraulically and include work platforms that climb with them to ensure precise and clean builds. Many types of self-climbing formwork either significantly reduce the amount of work involving cranes or do not require the use of cranes to move up levels. This is one of their major advantages.Formwork that is not self-climbing often requires a sizeable amount of crane use and time when tall, vertical concrete structures are being formed. With self-climbing formwork, cranes are freed up and consequently projects can be sped up. This type of formwork also enables vertical as well as horizontal sections to be assembled at the same time. This ultimately translates to faster project completion, lessened congestion at project sites, higher productivity, and higher quality construction.

Other benefits of using self-climbing formwork include:

• Increased safety
• Forms support themselves as they move up levels
• Easy to clean and re-use
• Attached scaffolding/work platforms
• Sturdy and can withstand harsh winds and inclement weather
• Relatively affordable to use when considering long-term value and retention of value
• A quick and easy process for workers who know what they’re doing
• The ability to sell for a profit if forms are no longer needed
• Simplifies planning of repetitive construction

Applications

Self-climbing formwork like jump formwork and slipform is becoming increasingly popular for construction involving:

• Skyscrapers
• Tall residential buildings (high rises)
• Bridge pylons
• Silos
• Elevator shafts
• Energy buildings
• Airport traffic control buildings

Self-climbing formwork is useful for practically anything that involves creating concrete structures that repeat vertically to significant heights.

Types of Self-Climbing Concrete Formwork

As we mentioned, jump system formwork and slipform are two popular types of self-climbing concrete formwork. The major difference between them is that jump system formwork involves pouring concrete and allowing it to set in jumps. Each level or module of concrete is poured and sets before moving up to the next vertical level. Slipform, on the other hand, climbs up slowly while concrete is being poured (in one long continuous pour). We outline some of the other differences in more detail between these two types of self-climbing formwork in another article. They both create similar end results and serve similar purposes and are suited to many of the same applications.Certain types of jump system formwork may rely on cranes to lift formwork to each vertical level. This type of formwork is not considered “self-climbing” and comes with some of the benefits of self-climbing jumpform with some potential added complications due to the use of cranes.Overall, self-climbing formwork can be an excellent investment for a variety of construction projects that involve tall, vertical concrete structures. This is especially the case when you consider the resale value of this type of formwork and the fact that it can be re-used for future projects as needed.

Wide flange beams are a type of support material commonly used in the construction of homes, commercial buildings, floors, roofs, bridges, highway ramps and overpasses. Typical applications include temporary support work, structural foundations and retention walls.Wide flange beams include a central web that connects two parallel end units, known as “flanges.” While the flanges in a standard beam are relatively narrow, those in a wide flange are much broader, sometimes even equal in length to the height of the web.Wide flange beams have high loadbearing capacity while also being light in weight, which is what makes them a popular choice in construction and foundation projects.

The Differences Between Wide Flange Beams and I-Beams

Wide flange beams and the traditional I-beams differ in shape. Wide flange beams resemble an “H,” meaning that the flanges are about the length of the web height. I-beams, on the other hand, more closely resemble the letter “I,” where the flanges are shorter than the web height.

How Wide Flange Beams Are Made

Wide flange beams are manufactured through a process called caliber rolling. First, steel is rolled by caliber rolls in order to create a cross-sectional shape. This process is called “rolling” because the beam blank (the unformed length of steel) is heated and then rolled out, similar to how dough is rolled with a rolling pin.After caliber rolling, the beam is fed through a universal mill for finetuning. Within the universal mill, there H-rolls and V-rolls that are moved horizontally and vertically along the beam, ensuring that the beam stays in place while forming the steel into the H-shape.The H-shaped cross-section is fully formed when the material passes through the universal mill. The beam can also be fed through an edging mill to adjust the flange widths.

Materials Used to Make Wide Flange Beams

Steel is the most common material used to make wide flange beams. Specifically, carbon structural steel and high-strength, low-alloy structural steel are used. Steel is favored because it’s highly customizable, durable, easy to work with and long lasting.

Wide Flange Beam Capacity

Wide flange beams range in weight bearing capacity from nine pounds per foot all the way above 350+ pounds per foot. When looking at the best beam size for any project, it’s important to consider the force that will be applied to be beam, the weight the beam will carry, and the tension and compression the beam will undergo. Smaller beams work well when the pressure and weight is minimal, while larger, thicker beams should be used to support structures that bear large amounts of weight.

Custom Rolled vs. Stock Wide Flange Beams

For many projects, standard stock beam sizes will be sufficient, as these cover the need of most projects. However, for unique projects, custom rolled beams might be necessary. Typically, it is more expensive to buy custom rolled beams.If adjustments for size need to be made, this is done during the manufacturing process with the universal mill. However, when beams with different web heights and flange widths are to be rolled, rolls made exclusively for these sizes will be employed instead.By combining caliber rolling with universal rolling, steel products of non-H shape can also be created, such as sheet piles and rails.

Wide Flange Beams ASTM and Sizes in the U.S.

Wide flange beams are available in eight ASTM standards including:

• A36
• A572 Grade 50
• A588
• A690
• A709
• A913 Grade 50
• A913 Grade 65
• A992

The A36 standard has yield strength of 36 ksi and the A572, A588, A690, A709, A913 and A992 have a yield strength of 50 ksi. A913 has a yield strength of 65 ksi.__Common wide flange beam sizes for bridge foundation projects include both large and small beams, which are:

Pile beams create a foundation for heavy structures like buildings, bridges and roads. The piles are made of steel that’s driven or drilled into the ground in order to help distribute the weight of a structure from the loose topsoil down to the stronger soil or rock below.H-piles are one of several different types of piling. They’re as wide as they are deep and have the same thickness in the flange and web. When compared to standard beams, H-pile beams provides better weight distribution over a wider area. Because of this, H-piles can support larger and heavier structures, such as tall buildings and factories. Individual piles have been tested to withstand loads of 1,000 tons. The high loadbearing capacity of H-piles allows large buildings to be built without the risk of weakening beams. Although they can be designed for skin friction, the H-pile shape is most effective at transferring loads through the pile to the end.[](https://www.eiffeltrading.com/marketplace/construction-material/h-pile/250ac97c-25a6-1ade-0ed3-c266580c16fd?utmsource=Website&utmmedium=blog&utm_campaign=Blog%20Redirect "Eiffel Trading H-Pile Listings")

Process of Manufacturing and Rolling H-Pile Beams

Rolling is the name for the process that is used to create H-pile beams. First, a beam blank (an undeveloped length of steel) is heated to make it pliable. The steel is then rolled using caliber rolls in order to form the beam into a rough H-shape. After the rolling is finished, the beam will undergo fine tuning using a universal mill and an edging mill. Within the universal mill, there are more rollers called H-rolls and V-rolls (which stand for horizontal rolls and vertical rolls), which run along the top, bottom and sides of the beam to shape it, while at the same time holding it in place. The H-shaped cross-section becomes fully formed when the material passes through the universal mill.

Materials Used in H-Pile Beams

While H-pile beams can be crafted from new steel, they’re often made from recycled steel, or “scrap.” The recycled steel used to make H-pile is usually in good condition or sometimes brand new. New steel might be sold as “used” or “surplus” if the steel was left over from another project, such as in instances where more steel was ordered than needed.One of the benefits of H-pile is that it’s 100 percent recyclable. This means it can be pulled from the ground and reused decades after use, making it one of the most environmentally friendly piling materials available.

H-Pile Beam Sizes

In the past, H-pile has only been manufactured in 8-, 12- and 14- inch sizes. Today, H-piles come in 16- and 18-inch sizes as well. Common wide flange beam sizes for bridge foundation projects are:

• HP8 Beams: HP8x36
• HP 10 Beams: HP10x42, HP10x57
• HP 12 Beams: HP12x53, HP12x63, HP12x74, HP12x84, HP12x89, HP12x102, HP12x117
• HP 14 Beams: HP14x73, HP14x89, HP14x102, HP14x117
• HP 16 Beams: HP16x88, HP16x101, HP16x121, HP16x141, HP16x162, HP16x183
