SHS 135x135x4 Cintac · Weight & Dimensions

Cintac, 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 135x135 cal 8 (México) · Caño estructural 135x135 (Argentina)

The SHS 135x135x4 steel profile weighs 16.1 kg/m (10.84 lb/ft), has a depth of 135 mm (5.31 in), flange width 135 mm (5.31 in). Cross-sectional area: 2,054.796 mm². Moment of inertia Ix = 581.698 cm⁴, Iy = 581.698 cm⁴.
