AST PIPES brings to market the Grade YST 210 MS SHS AST YST 210 MS SHS - (25 x 25 x 1.4 mm) - 6 mtr Length, an IS 4923:2017-compliant ERW cold-formed square hollow section with 25 mm outer dimension, 1.4 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 and light fabrication requiring dimensional precision and weld integrity. Its square hollow form allows internal routing of cables and services while providing full structural functionality in framing and support applications.

• Cold-formed ERW square 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 square geometry enabling flush-face connections without packing plates
• Consistent internal dimensions suitable for sleeve joints and end-plate connections
• Surface free from major rolling defects for seamless paint or 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 applications
• Produced under controlled rolling and forming conditions for batch-to-batch consistency
