AST PIPES brings to market the Grade YST 240 MS SHS AST YST 240 MS SHS - (32 x 32 x 2.8 mm) - 6 mtr Length, an IS 4923:2017-compliant ERW cold-formed square hollow section with 32 mm outer dimension, 2.8 mm wall thickness, and 6 m standard length. Certified to achieve a minimum yield of 240 MPa and UTS of 360 MPa, this section is optimised for medium-duty structural and industrial framing 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 240
• Four flat external faces providing maximum bearing area for connection hardware
• Minimum 240 MPa yield and 360 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

• Structural columns for ground-floor retail and commercial buildings
• Primary framing members in PEB and conventional steel buildings
• Medium industrial platform supports, catwalks, and access structures
• Overhead crane runway supports and monorail beam hangers
