Sourced from RR MetalMakers's certified production line, the RR MetalMakers YST 310 MS RHS - (250 x 150 x 5 mm) - 6 mtr Length is an ERW Rectangular Hollow Section in YST 310 steel built to the requirements of IS 4923:2017 (Hollow Steel Sections for Structural Use). The 250 mm × 150 mm × 5 mm hollow section across 6 m lengths provides superior stiffness-to-weight performance with high yield strength for critical load-bearing structures, making it a preferred structural element for heavy engineering, crane structures, and high-load frameworks. Clean, uniform surfaces and consistent mechanical properties ensure seamless integration in both welded and bolted connection designs.
