SHS 88.9x88.9x4 Hylsa · Weight & Dimensions

Hylsa, 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 88.9x88.9 cal 8 (México) · Caño estructural 88.9x88.9 (Argentina)

The SHS 88.9x88.9x4 steel profile weighs 10.2 kg/m (6.86 lb/ft), has a depth of 88.9 mm (3.50 in), flange width 88.9 mm (3.50 in). Cross-sectional area: 1,317.196 mm². Moment of inertia Ix = 155.69 cm⁴, Iy = 155.69 cm⁴.
