Square Hollow Section (SHS) Structural Tubes

Square Hollow Section (SHS) Structural Tubes from Newton are precision electric resistance welded structural tubes manufactured to IS 4923 for use in load-bearing frameworks, architectural facades, modern furniture and general structural fabrication. Their uniform square cross-section provides high bending and torsional strength in all directions, making them a preferred structural member wherever a clean, symmetrical profile is required alongside dependable load capacity.

Square Hollow Section (SHS) Structural Tubes

Newton manufactures SHS tubes from 20mm x 20mm up to 300mm x 300mm, with wall thicknesses from 1.6mm to 12mm, formed from hot-rolled steel coil through a continuous ERW process that ensures a straight, dimensionally accurate profile with tight tolerances on both size and squareness. Sections are available in black (mill) finish or hot-dip galvanized finish for corrosion-prone applications, and can be supplied cut-to-length or in standard mill lengths.

These structural tubes are used across building construction for columns, purlins and roof trusses, in industrial sheds and warehouses, in vehicle body-building and trailer chassis, and increasingly in contemporary furniture, staircases, railings and shopfitting where a visible, clean square profile is part of the design intent. Their high strength-to-weight ratio also makes them popular for scaffolding and temporary structures.

Every batch is verified for wall thickness, corner radius, straightness and mechanical properties (yield and tensile strength, elongation) in line with IS 4923, with mill test certificates issued against each dispatch. Newton offers both standard commercial grades and higher-yield structural grades depending on the design load requirement of the project.

As an export partner, Newton sources SHS tubes from India’s leading ERW tube producers and manages order consolidation across sizes, thicknesses and finishes into a single documented shipment. Buyers receive full mill traceability, packing lists itemized by size, and export documentation suited to construction, fabrication and furniture industry requirements worldwide.
