SHS 12.5x12.5x1.4 Acindar · Weight & Dimensions

Acindar, cold-formed sections · Square Hollow Section

Square Hollow Sections (SHS) are tubular profiles with equal sides, ideal for columns and compression members due to their uniform buckling resistance in all directions.

Also known as: PTR 12.5x12.5 cal 18 (México) · Caño estructural 12.5x12.5 (Argentina)

The SHS 12.5x12.5x1.4 steel profile weighs 0.5 kg/m (0.30 lb/ft), has a depth of 12.5 mm (0.49 in), flange width 12.5 mm (0.49 in). Cross-sectional area: 57.113 mm². Moment of inertia Ix = 0.112 cm⁴, Iy = 0.112 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1.4 mm ≈ 16 gauge (Manufacturers Standard Gage)
