ISA 50×50×6 Weight, Dimensions and IS 808 Properties
ISA 50×50×6 weighs 4.5 kg per metre as per IS 808:1989.
- One 6-metre length weighs 27.0 kg · one 12-metre length weighs 54.0 kg
- Leg 50 mm × thickness 6 mm · root radius 7.0 mm
- Cross-sectional area 5.69 cm² · Iuu = 11.9 cm⁴
ISA 50×50×6 is the heavier 50 mm equal-leg angle in IS 808:1989. At 4.5 kg/m it provides 18.5% more cross-sectional area than ISA 50×50×5, used where higher axial capacity is required in truss members and bracing without increasing leg size.

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 50×50×6
ISA 50×50×6 is used for loaded truss web and chord members, back-to-back compound struts under higher compression, bracing members in medium-span structures, and bolted connection cleats requiring greater bearing capacity. Stocked by JSPL, Tata Steel, and RINL.
Worked Example
A fabricator in Chennai needs 20 compression web members of ISA 50×50×6, each 1.8 m long, for a 12 m span Pratt truss. Total length = 20 × 1.8 = 36 m. Weight = 36 × 4.5 = 162 kg. At ₹62,000 per tonne (Chennai, May 2026), material cost is approximately ₹10,044.
