Rectangular Hollow Section is a pipe material with a hollow structure and a square cross-section.
Performance and Application of Rectangular Hollow Section
Rectangular Hollow Section (SHS) pipes are constructed from four welded steel plates and offer excellent bending resistance. They resist deformation and denting under pressure, have a well-balanced torsional stress distribution, and offer high torsional rigidity. They also feature a simple appearance and smooth pipe edges. They are commonly used in building frames, vehicle chassis, highway bridges, and other industries.
