General Construction Steel has Pure steel, micro-alloying with good mechanical properties and weldability; high strength, stable yield strength , and has a low rate of tensile strength and yield strength.General Construction Steel usually be for the manufacture of high-rise building, can reduce the thickness of steel timber to enhance its manufacturing reliability, thereby reducing the weight of structural parts to reduce construction costs, and ensure the safety of the building life.
The main grade of General Construction steel are:
