H-beams can be produced by welding or rolling. Welded H-beam is to cut strip of suitable thickness to suitable width, and weld the flange and web together on a continuous welding unit. Welded H-beam has the disadvantages of large metal consumption, difficult to ensure uniform product performance, and limited size specifications. Therefore, H-beams are mainly produced by rolling method. In modern steel rolling production, H-beams are rolled using universal rolling mills. The web of the H-beam is rolled between the upper and lower horizontal rolls, and the flanges are rolled and formed simultaneously between the side of the horizontal roll and the vertical roll. Since only the universal rolling mill cannot press down the flange edge, it is necessary to set an edge rolling machine behind the universal stand, commonly known as the edge rolling machine, in order to press down the flange edge and control the flange width. . In the actual rolling operation, the two stands are used as a group, and the rolling stock is reciprocated through several times (Fig. 2a), or the rolling stock is passed through several universal stands and one or two edger stands. The continuous rolling line consists of a certain reduction amount for each pass to roll the billet into a product of the required shape and size. At the flange part of the rolling piece, due to the sliding between the side of the horizontal roll and the rolling piece, the wear of the roll is relatively large. In order to ensure that the rolls can be restored to their original shape after heavy rolling, the sides of the upper and lower horizontal rolls of the roughing mill and the surfaces of the corresponding vertical rolls should be inclined at an angle of 3° to 8°. In order to correct the inclination angle of the finished flange, a finished universal rolling mill, also known as a universal finishing mill, is set up. The side of the horizontal roll is perpendicular to the axis of the horizontal roll or has a small inclination angle, generally not more than 20&#;, and the vertical roll is cylindrical (Figure 2d). ).

When H-beam is rolled with a universal rolling mill, the section of the rolled piece can be extended more uniformly, and the speed difference between the inner and outer roll surfaces of the flange is small, which can reduce the internal stress and appearance defects of the product. By appropriately changing the reduction amount of the horizontal and vertical rolls of the universal rolling mill, H-beams of different specifications can be obtained. The shape of the roll of the universal rolling mill is simple, the shape is simple, the service life is long, and the consumption of the roll can be greatly reduced. The biggest advantage of H-beam rolling by universal rolling mill is: In the same dimension series, only the thickness dimension of the web and flange is changed, and the dimensions of other parts are fixed. Therefore, the same series of H-beams rolled with the same universal pass has a variety of web and flange thickness specifications, which greatly increases the number of H-beam specifications and brings great convenience for users to choose suitable size specifications.

In the absence of a universal rolling mill, sometimes in order to meet the urgent needs of production and construction, a vertical roll frame can also be added to an ordinary two-high rolling mill to form a universal pass for rolling H-beams. Rolling H-beam in this way has low dimensional accuracy of the product, it is difficult to form a right angle between the flange and the web, the cost is high, and the specifications are small. It is extremely difficult to roll H-beam for columns, so there are not many users.

H-pile beams are required when the ground under a building or a bridge cannot support its weight. This might happen if the building is too tall or if the ground is too soft. In either situation, a deep foundation system must be designed to transfer the foundation loads down through the steel piles to the denser rock or soil layers below.

H-piles are square in shape, meaning they are as wide as they are deep. They have the same thickness in the flange and web. Unlike standard beams, the design of an H-pile beam allows for better weight distribution over a wider area, which results in the ability to support heavier structures.

H-piles are commonly used as bearing piles in deep foundation applications and are driven into the ground to support bridges, buildings, factories and other large structures. H-piles are also used in other applications as bracing systems for cofferdams, and in beam and lagging walls. Finally, steel H-piles are commonly used for deep foundation and marine structures.

Process of Manufacturing and Rolling H-Pile Beams

H-pile beams are produced through a process called rolling. First, a beam blank (an unformed length of steel) is heated to make it malleable. The steel is then rolled using caliber rolls in order to form the beam into a rough H-shape. After the rolling is complete, 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

Steel is commonly used to make H-pile beams because it&#;s highly customizable, durable, easy to work with and long lasting. While H-pile beams can be crafted from new steel, they&#;re often made from recycled steel, or &#;scrap.&#; It&#;s a common misconception that recycled steel must be old or corroded, but this isn&#;t always the case. The recycled steel used to make H-pile is often 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.

H-pile is 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.

H-Pile Beam Sizes

H-Piles are structural beams that are dimensionally square. This design allows H-piles to transfer structural loads to stronger soil layers deep below the initial layers. H-piles are commonly available in 8", 10", 12", and 14" lengths. However, 16&#; and 18&#; piles can also be found.

In regards to weight bearing capacity, individual piles can support as much as 1,000 tons. These piles are more efficient in dense soils that offer pile resistance at the tip for point bearing capacity. When constructing a pile system on rock, steel H-piles are considered the best and most reliable option.
