SHS 305x305x6.4 IMCA · Weight & Dimensions

IMCA, 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 305x305 cal 3 (México) · Caño estructural 305x305 (Argentina)

The SHS 305x305x6.4 steel profile weighs 58.8 kg/m (39.48 lb/ft), has a depth of 305 mm (12.01 in), flange width 305 mm (12.01 in). Cross-sectional area: 7,538.679 mm². Moment of inertia Ix = 11,123.273 cm⁴, Iy = 11,123.273 cm⁴.
