Description
Hariom YST 355 Rectangular Hollow Section Hariom YST 355 MS RHS - (145 x 82 x 4.8 mm) - 6 mtr Length is produced by ERW cold-forming to IS 4923:2017 with a 145 mm x 82 mm cross-section and 4.8 mm wall thickness in standard 6 m lengths. Delivering minimum yield of 355 MPa and tensile strength of 490 MPa, this RHS is engineered for high-strength structural beams, heavy industrial frames, and demanding spanning applications where directional load resistance and weld quality are critical. The four flat external faces and controlled corner radii simplify connection detailing and allow precise fit-up in fabricated beams, frames, and trusses.
Key Features:- Grade YST 355 IS 4923:2017 certified RHS with guaranteed mechanical properties
- ERW process producing a continuous, sound weld seam along the full tube length
- Yield 355 MPa and tensile 490 MPa for design-critical structural applications
- Rectangular hollow geometry offering high section modulus-to-weight ratio
- Greater depth enables increased span capacity and reduced structural deflection
- Mill surface suitable for direct fabrication, painting, or hot-dip galvanizing treatment
- Comprehensive range of sizes from light profiles to heavy structural sections
- Standard 6 m lengths compatible with standard transport and storage infrastructure
- Good notch toughness and elongation for structural safety under impact loads
- Dimensional accuracy per IS 4923 tolerances for interchangeable and reliable fit-up
- Primary structural spanning beams in warehouses and distribution centres
- Long-span truss chord members in airports and large public hall structures
- Structural sections for oil and gas platform topsides and primary deck beams
- Rail and road bridge primary structural beam and girder spanning sections
- Heavy crane gantry spanning girders and crane main structural beam members
- Primary structural beams in stadiums, arenas, and long-span grandstand roofs
- High-axial-load beam members in transfer floors of high-rise buildings
- Structural spanning sections in high-rise building perimeter and core frames
