20×20×2 SHS Weight, Dimensions and IS 4923 Properties
20×20×2 SHS weighs 1.13 kg per metre as per IS 4923:1997.
- One 6-metre length weighs 6.78 kg · one 12-metre length weighs 13.56 kg
- 20 × 20 mm square section · wall thickness 2.0 mm
- Cross-sectional area 1.44 cm² · Ixx = 0.49 cm⁴
The 20×20×2 mm SHS is the smallest standard square hollow section in IS 4923:1997. At 1.13 kg/m it is used for light furniture frames, handrail infill sections, decorative grille panels, and minor fixtures where a small square tube is needed. Manufactured by Tata Structura, APL Apollo, and general tube mills in YST 210 and YST 240 grade.

Common Applications of 20×20×2 SHS
The 20×20×2 SHS is used wherever a small, neat square tube is required: furniture legs and frames, gate infill balusters, decorative grille panels, light brackets, and display stand structures. Its 20 mm outside dimension fits standard slot-in fittings and corner connectors used in modular furniture. APL Apollo and Tata Structura supply this size in YST 210 and YST 240 grade from stock at most steel service centres.
Worked Example
A fabricator in Pune is making 40 chair frames, each requiring four legs of 20×20×2 SHS cut to 420 mm. Total length = 40 × 4 × 0.42 = 67.2 m. Weight = 67.2 × 1.13 = 75.9 kg. At a market rate of ₹72,000 per tonne (May 2026), the material cost is approximately ₹5,468 before fabrication.
