ISA 130×130×12 Weight, Dimensions and IS 808 Properties
ISA 130×130×12 weighs 23.4 kg per metre as per IS 808:1989.
- One 6-metre length weighs 140.4 kg · one 12-metre length weighs 280.8 kg
- Leg 130 mm × thickness 12 mm · root radius 13.0 mm
- Cross-sectional area 29.78 cm² · Iuu = 430.0 cm⁴
ISA 130×130×12 is the heavier 130 mm equal-leg angle in IS 808:1989. At 23.4 kg/m it provides 19% more cross-sectional area than ISA 130×130×10, used for heavily loaded primary chord members and compound column sections in large heavy industrial structures.

Dimensions and properties as per IS 808:1989 (Reaffirmed 2001). Mass tolerance: ±3% per piece as per IS 808. u–u is the major principal axis at 45° to both legs; v–v is the minor principal axis. Zvv is not published in IS 808:1989 for angle sections.
Common Applications of ISA 130×130×12
ISA 130×130×12 is used for heavily loaded primary truss chord members in large industrial buildings, back-to-back compound column sections under very high axial load, primary heavy wind bracing, and large bolted connections at major structural joints. Available from JSPL and Tata Steel.
Worked Example
A structural engineer in Delhi specifies ISA 130×130×12 for 8 primary chord members, each 6 m long, for a heavily loaded 32 m span truss in a steel processing plant. Total length = 8 × 6 = 48 m. Weight = 48 × 23.4 = 1,123.2 kg (1.123 tonnes). At ₹62,000 per tonne (Delhi, May 2026), material cost is approximately ₹69,638.
