SHS 203x203x6.4 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 203x203 cal 3 (México) · Caño estructural 203x203 (Argentina)

The SHS 203x203x6.4 steel profile weighs 38.4 kg/m (25.83 lb/ft), has a depth of 203 mm (7.99 in), flange width 203 mm (7.99 in). Cross-sectional area: 4,927.479 mm². Moment of inertia Ix = 3,139.562 cm⁴, Iy = 3,139.562 cm⁴.
