TCharacteristics of section steel:

1Strong overall structure, High strength, Directly usable as column support overhead beam.TSteel strip bending section modulus enhancement37Multiple;
2Exquisite design,TSteel strip designed with double holes,Compensates for the adverse factors to support caused by the failure of individual anchor ropes or bolts.,Re-thread and re-drive anchor rope or anchor rod,To ensure overall safety and reliability;

3High efficiency,Anchors and anchor ropes both pass throughTReinforced steel strip,Saved on anchor rod trays, anchor cable trays, labor and material savings,有利于提高掘进速度； Enhances tunneling speed;

4High strength, lightweight, cost-effective, finely crafted, easy and quick installation, high support strength, and safety and reliability.

5、THot-rolled steel strip offers better support effects with one-time forming, ensuring stable quality and low cost.

6High cross-sectional utilization, material-saving, and low-priced.

7、TSection steel is a carbon structural steel used for construction, featuring simple cross-sections. It is primarily used in metal structures and the frames of buildings. It requires good weldability, plastic deformation properties, and certain mechanical strength during use.

8、TThe national standards for section steel include the following three types::
