SHS 45x45x2.5 Hiasa · Weight & Dimensions

Hiasa, 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 45x45 cal 13 (México) · Caño estructural 45x45 (Argentina)

The SHS 45x45x2.5 steel profile weighs 3.2 kg/m (2.16 lb/ft), has a depth of 45 mm (1.77 in), flange width 45 mm (1.77 in). Cross-sectional area: 408.905 mm². Moment of inertia Ix = 12.058 cm⁴, Iy = 12.058 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.5 mm ≈ 12 gauge (Manufacturers Standard Gage)
