I-beams

I-beams are widely used in buildings and other metal structures. Whether ordinary I-beams or light I-beams (such as H-beams), their section height is typically 100–900 mm, and the section width is about 50–300 mm.

The moment of inertia of the section along the two main axes can reach 10³–10⁷ cm⁴, so they are usually used directly as web-plane bending members or as load-bearing members in lattice structures.

In structural design, the selection of I-beams should be based on their mechanical properties (yield strength 235–355 MPa, tensile strength 370–510 MPa), chemical properties (carbon content ≤0.22%), weldability, structural dimensions, and other factors to choose the appropriate I-beam reasonably.

Advantages of I-Beams

Design Flexibility: I-beams have excellent plasticity, making cutting, bending, and welding easy. Their design flexibility also allows precise adjustments according to actual requirements. For example, the bending radius can reach 1.5–2 times the section height, and the welding temperature range is 650–750℃.

Strong Durability: I-beams exhibit outstanding aging resistance and a long service life of over 50 years. Their impact strength can reach 120–200 J/cm², and their wear resistance surpasses many other construction steels, ensuring stability and durability during use.

Light Weight: The weight of I-beams ranges from 10–200 kg/m depending on the section. The construction process is simple and fast, saving about 20–30% of construction time and effectively improving project progress.

Good Physical Properties: I-beams also have good insulation, magnetic permeability (0.001–0.01 H/m), and excellent fire resistance (fire rating A1) and thermal insulation properties.

Comprehensive Coating Protection: The galvanizing layer, typically 50–100 μm thick, is metallurgically bonded to the steel, providing durable and reliable protection. Galvanization can cover every part of the component, including recesses, corners, and hidden areas.
