Steel type：

Carbon steel: low carbon content, good toughness and plasticity, widely used in construction, bridges and other projects.

Low-alloy high-strength steel: The strength and corrosion resistance of steel are improved by adding a small amount of alloying elements (such as manganese, silicon, nickel, etc.).

Stainless steel: Contains chromium, nickel and other elements, has excellent corrosion resistance, and is often used in chemical plants, food processing and other places with high environmental requirements.

Cross-sectional form

I-beam: It has large bending and torsion resistance and is suitable for load-bearing structures.

H-Beam: The cross-section size is relatively large and is often used in large structures such as high-rise buildings and bridges.

Channel Steel: used in building structures, mechanical equipment, etc.

Angle Steel: Suitable for connectors, support structures, etc.
