Structural Steel

Structural Steel can be classified into carbon structural steel and alloy structural steel according to its chemical composition. The carbon structural steel, such as Q235, is used in building frameworks like factories and bridges. The alloy structural steel, with added alloying elements, like 40Cr, is used for mechanical parts such as shafts and gears.

●Key Advantages
High Strength:  It can bear heavy loads and is used in high - rise buildings and long - span bridges, enhancing the bearing capacity and stability.
Excellent Plasticity and Toughness:  It can be deformed without sudden fracture, absorbs energy well, and improves seismic and impact resistance.
Good Weldability:  It is easy to weld into an integral structure, ensuring integrity and reliability.
Easy to Process:  It is suitable for forging, rolling, and cutting, and can be made into various components to meet different needs.
Partial Corrosion Resistance:  Structurally - steel with special treatment is suitable for humid and corrosive environments.
