Product description: 

A beam is a structural element that supports a building or structure. It can be either primary support or secondary support and is generally used to bear a load from some other member, such as a foundation or the outer walls.

Beams are classified by their shapes (I-beams, L-beams, box beams) and sizes (2×4, 2×6). They’re also classified by their material and how they’re attached to the structure of the building. Beams are generally made from wood, steel or concrete. In addition to these materials, some beams can be made with bamboo or balsa wood as well.

Beams are often used when constructing buildings because they allow for easy installation of wiring and piping without having to worry about overworking any one part of the building too much.

The inner and outer sides of the flange of H-shaped steel are parallel or nearly parallel, and the end of the flange is at right angles, so it is named parallel flange I-beam. The web thickness of H-shaped steel is smaller than that of ordinary I-beam with the same height as the web, and the flange width is larger than that of ordinary I-beam with the same height as the web, so it is also called wide edge I-beam. Determined by the shape, the section modulus, inertia moment and corresponding strength of H-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in terms of bending moment, pressure load and eccentric load. It can greatly improve the bearing capacity and save 10% ~ 40% of metal compared with ordinary I-beam. H-shaped steel has wide flange, thin web, many specifications and flexible use. It can save 15% ~ 20% of metal when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge ends are at right angles, it is convenient to assemble and assemble various components, which can save about 25% of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.

H Steam
H-section steel is a kind of economical section and high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its section is the same as the English letter “H”. Since the various parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light structure in all directions.

HE-B steel beam, also called H-beam. The H-beam is square with equal height and width.
The construction provides the beam with great strength and rigidity. The form of the beam prevents bending of the transverse parts.

A steal beam is suitable for both indoor and outdoor use. However, it will rust over time, when it is exposed to the humidity of the air. Therefore, it rusts faster outdoor. If you would like to encourage the corrosion process, water can be added.
The steel H-steel beam can be used for enforcement of tiers of beams, poles, a bearer over a door or window, etc.

Production Process

H-Beam and I-Beam: Applications

H-Beams and I-beams are very similar, but they have different applications. If you’re interested in using either of them for your next project, here’s what you need to know:

• The best way to determine which beam is best for your project is to consult a professional. H-beams are better suited to support the load of the floor and roof over longer distances, while i-beams are better suited to support the weight of a wall or column.
• If you do decide on an H-beam or an I-beam, note that these beams have different minimum spans; this means that if your space has a large span (i.e., it’s long), then an I-beam may not be right for it because it requires more material than other designs.
