SHS 200x200x6.4 Açotubo · Weight & Dimensions

Açotubo, 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 200x200 cal 3 (México) · Caño estructural 200x200 (Argentina)

The SHS 200x200x6.4 steel profile weighs 38.1 kg/m (25.59 lb/ft), has a depth of 200 mm (7.87 in), flange width 200 mm (7.87 in). Cross-sectional area: 4,850.679 mm². Moment of inertia Ix = 2,996.491 cm⁴, Iy = 2,996.491 cm⁴.
