Description
Precision-formed and IS-certified, the Champak Steel YST 310 MS RHS - (40 x 30 x 3 mm) - 6 mtr Length from Champak Steel is a cold-rolled ERW RHS in YST 310 structural steel conforming to IS 4923:2017 (Hollow Steel Sections for Structural Use). The 40 mm × 30 mm × 3 mm rectangular profile in 6 m lengths meets the exceptional yield strength enabling slender, efficient sections under heavy loads demanded by heavy-duty structural, high-load, and long-span applications, with tight wall-thickness tolerance, consistent straightness, and a smooth external finish. The greater section depth maximises second moment of area in the major axis for efficient beam and purlin design.
Key Features:- YST 310 grade steel with minimum yield strength 310 MPa and tensile strength 450 MPa
- Rectangular hollow profile 40 mm × 30 mm × 3 mm — optimised for major-axis bending resistance
- Uniform wall thickness of 3 mm maintained throughout the full 6 m length
- Cold-formed ERW manufacturing ensuring consistent, high-integrity weld seam quality
- Conforms to IS 4923:2017 — IS-marked with full batch mill certification
- High strength-to-weight ratio enabling leaner, lighter structural designs
- Excellent weldability — compatible with MIG, TIG, and SMAW electrode processes
- Tight dimensional tolerances on depth, width, and wall within IS permissible limits
- Square-cut ends for precise measurement and clean joint fitting on site
- Smooth mill-finish external surface ready for painting, galvanising, or powder coating
- Roof beams, purlins, and rafters in industrial and commercial building structures
- Pre-Engineered Building (PEB) rafters, eave struts, and secondary structural members
- Truss top and bottom chord members in heavy-duty roof and bridge trusses
- Mezzanine floor beams, equipment platform girders, and elevated walkway spans
- Conveyor support beams, material-handling gantry girders, and overhead crane runway beams
- Portal frame haunched rafters and eave beams in PEB and industrial construction
- Mining and processing plant structural girders and ore-chute support beams
