RHS and SHS tubeare a welded structural grade tubing,depending on its size and wall thickness. Either grade is ideal for all structural applications, general fabrication, manufacturing and repairs.
Square hollow sectionis widely used in industrial maintenance, agricultural implements, transportation equipment, truck beds, trailers, frames, etc. Its box-shape configuration allows for much greater strength and rigidity compared to angles or channels.
