SHS 300x8
EN — 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 300x300 (México) · Caño estructural 300x300 (Argentina)
The SHS 300x8 steel profile weighs 70.4 kg/m (47.31 lb/ft), has a depth of 300 mm (11.81 in), flange width 300 mm (11.81 in). Cross-sectional area: 9,344 mm². Moment of inertia Ix = 13,288.41 cm⁴, Iy = 13,288.41 cm⁴.
