AST PIPES presents the Grade YST 210 MS RHS AST YST 210 MS RHS - (45 x 35 x 1.2 mm) - 6 mtr Length, an IS 4923:2017-compliant ERW cold-formed rectangular hollow section with 45 mm depth, 35 mm width, 1.2 mm wall thickness, and 6 m standard length. Certified to achieve a minimum yield of 210 MPa and UTS of 330 MPa, this section is optimised for general structural, light framing, and furniture-grade 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 in steel construction.

• Cold-formed ERW rectangular hollow section to IS 4923:2017 Grade YST 210
• Four flat external faces providing maximum bearing area for connection hardware
• Minimum 210 MPa yield and 330 MPa UTS meeting structural design 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
• Suitable for cold punching, drilling, sawing, and plasma cutting on-site
• Closed cross-section superior to open sections in torsion-critical beam applications
• Produced under controlled rolling and forming conditions for batch-to-batch consistency

• Lightweight spanning lintels in residential and light commercial construction
• Pergolas, canopies, carports, and shade sail support beam members
• Custom interior designer furniture, tables, and metal fabrications
• Secondary framing in mezzanine floors and raised platform decks
• Portable and demountable site structures, kiosks, and cabins
• Cable management tray supports and electrical containment frames
• Light truss chord and purlin members in decorative roof structures
• Agricultural equipment frames, trailer bodies, and implement supports
