TCharacteristics of section steel:

1Strong in overall integrity, High strength, Directly usable as a column support top beam.TImproved bending section modulus of steel strip37Multiple
2Exquisite design,TSteel strip designed with double holes,Compensates for the adverse effects on support due to failure of individual anchor ropes or bolts,Replace hole and re-drill anchor rope or anchor rod,To achieve overall safety and reliability.

3Efficient,Anchors and anchor ropes both pass throughTSteel strip reinforcement,Saved on anchor rod trays, anchor cable trays, labor and material savings,Enhances tunneling speed.

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

5、THot-rolled steel strip, once formed, offers better support, stable quality, and low cost advantages.

6High cross-sectional efficiency, material-saving, and low cost.

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

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

   GBT 11263-2010Hot rolled splitTStandard H-beams

   GBT 11263-1998Hot-rolled splitTStandard steel sections

   GBT 11263-2005Hot-rolled splitTStandard Section Steel.
