TCharacteristics of steel sections:

1Strong overall integrity, High strength, Direct-to-column joist beams, suitable as support headers.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.,Replaceable hole for re-tensioning anchor rope or anchor rod,To ensure overall safety and reliability.

3Efficient,Anchors and anchor ropes both pass throughTReinforced steel strip,Saved on anchor rod trays, anchor cable trays, labor and material savings,Beneficial for enhancing 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 provides better support with a single molding process, featuring stable quality and low cost.

6High section utilization, material-saving, and affordable pricing.

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

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