TCharacteristics of steel sections:

1Strong overall integrity, High strength, Directly usable as a column support, top girder.TImproved bending section modulus of steel strip37Multiple;
2Exquisitely designed,TSteel strip designed with double holes,Compensates for the adverse factors to support caused by the failure of individual anchor cables or rods.,Replace hole for re-tapping anchor rope or anchor bolt,To achieve overall safety and reliability.

3Efficiency high,Anchors and anchor cables both pass throughTSteel strip reinforced,Saved on anchor rod trays, anchor cable trays, labor and material savings,Enhances tunneling speed.

4High strength, lightweight, low cost, fine craftsmanship, easy and quick installation, high support strength, and safety reliability.

5、THot-rolled steel strip with one-time forming has better supporting effects, stable quality, low cost, and other advantages.

6High section utilization, material-saving, and low-priced.

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. It requires good weldability, plastic deformation properties, and a certain level of mechanical strength during use.

8、TThere are three national standards for steel sections.:
