Combining equal-axis strength with precise dimensional accuracy, the RR MetalMakers YST 310 MS SHS - (300 x 300 x 6 mm) - 6 mtr Length from RR MetalMakers is a cold-formed ERW SHS in YST 310 structural steel conforming to IS 4923:2017 (Hollow Steel Sections for Structural Use). The 300 mm × 300 mm × 6 mm cross-section in 6 m lengths achieves an optimal balance of axial capacity, bending resistance, and fabrication ease for heavy engineering, crane structures, high-rise bracing, and bridge frames. With a minimum yield of 310 MPa and tensile of 450 MPa, this section is engineered to meet the performance demands of heavy-duty structural, high-load, and long-span applications with consistent, traceable quality.
