The RR MetalMakers YST 310 MS RHS - (40 x 20 x 6 mm) - 6 mtr Length is a structurally certified Rectangular Hollow Section from RR MetalMakers in YST 310 mild steel, conforming to IS 4923:2017 (Hollow Steel Sections for Structural Use). The 40 mm × 20 mm × 6 mm hollow profile in 6 m standard lengths achieves an optimal balance of bending resistance, load capacity, and ease of fabrication for heavy engineering, crane structures, and high-load frameworks. With minimum yield strength of 310 MPa and tensile of 450 MPa, this RHS is engineered to meet the performance expectations of heavy-duty structural, high-load, and long-span applications with consistent, traceable quality.
