Description
Hariom presents the Grade YST 355 MS RHS Hariom YST 355 MS RHS - (180 x 70 x 4.8 mm) - 6 mtr Length, an IS 4923:2017-compliant ERW cold-formed rectangular hollow section with 180 mm depth, 70 mm width, 4.8 mm wall thickness, and 6 m standard length. Certified to achieve minimum yield of 355 MPa and UTS of 490 MPa, this section is optimised for high-strength structural beams, heavy industrial frames, and demanding spanning applications requiring directional bending strength and dimensional accuracy. The rectangular hollow profile enables internal service routing while delivering full structural functionality as beams, lintels, and spanning members.
Key Features:- Cold-formed ERW rectangular hollow section to IS 4923:2017 Grade YST 355
- Four flat external faces providing maximum bearing area for connection hardware
- Minimum 355 MPa yield and 490 MPa UTS meeting structural design code requirements
- Precise rectangular geometry enabling flush-face connections without packing plates
- Consistent internal dimensions suitable for sleeve joints and end-plate connections
- Surface free from major defects for seamless paint or hot-dip galvanizing adhesion
- 6 m standard length for efficient stacking, handling, and transportation logistics
