SHS 50.8x50.8x2.8 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 50.8x50.8 cal 13 (México) · Caño estructural 50.8x50.8 (Argentina)

The SHS 50.8x50.8x2.8 steel profile weighs 4.0 kg/m (2.69 lb/ft), has a depth of 50.8 mm (2.00 in), flange width 50.8 mm (2.00 in). Cross-sectional area: 517.41 mm². Moment of inertia Ix = 19.466 cm⁴, Iy = 19.466 cm⁴.
