Description
The AST PIPES YST 310 MS RHS AST YST 310 MS RHS - (71.75 x 55.75 x 2.8 mm) - 6 mtr Length is manufactured through the ERW cold-forming process to comply with IS 4923:2017, featuring a 71.75 mm x 55.75 mm rectangular cross-section with 2.8 mm wall thickness in 6 m standard lengths. With a guaranteed yield strength of 310 MPa and tensile strength of 450 MPa, this hollow section provides reliable mechanical performance for heavy structural, high-load bearing frames, and primary column applications. Its asymmetric rectangular geometry delivers enhanced major-axis bending capacity, optimising material efficiency in beam and lintel structural applications.
Key Features:- IS 4923:2017 Grade YST 310 compliant with traceable mechanical test certificates
- ERW welded with controlled heat input for uniform weld zone properties
- Certified yield strength of 310 MPa for structural engineering design calculations
- Rectangular geometry providing depth advantage for beam and spanning applications
- Consistent wall thickness across all four sides for uniform stress distribution
- Clean mill finish receptive to all protective coating systems including epoxy primers
- Standard 6 m cut lengths minimising on-site material wastage and splice joints
- Compatible with conventional bolted, welded, and mechanical fastening systems
- Low carbon equivalent supporting good cold-forming and field weldability
- UTS of 450 MPa providing adequate reserve strength under overload structural conditions
- Primary load-bearing beams in commercial and industrial high-span buildings
- Structural main chord and diagonal members in long-span lattice girders
- Foundation beam formers and ground beam structural members
- Heavy-duty equipment span frames in power and process plant facilities
- Rail infrastructure structural spanning members for overhead line gantries
- Crane rail primary support girders and hoist beam structural sections
- Primary structural spanning frames for sports arenas and exhibition halls
- Structural beams in petrochemical heavy industrial pipe rack systems
