Square Hollow Section (SHS)
A Square Hollow Section (SHS) is a welded steel tube with a uniform square profile manufactured using ERW or HFIW welding technology. Known for its high structural strength, dimensional accuracy, and superior load-bearing capacity, SHS is widely used in industrial sheds, building structures, machinery frames, furniture manufacturing, and engineering applications. Its smooth finish, consistent edges, and high strength-to-weight ratio make SHS a preferred choice for fabricators and architects.

Manufacturing Process
Our Square Hollow Sections (SHS) are sourced from advanced mills following a strict manufacturing process. High-quality hot-rolled or cold-rolled coils are uncoiled, inspected, and passed through forming rollers that shape them into a square profile. ERW/HFIW welding technology is used to fuse the edges, ensuring a strong, consistent seam. The welded tube then undergoes sizing, straightening, and shaping to achieve accurate square dimensions. After processing, the tubes are tested for weld integrity, tensile strength, dimensional accuracy, and surface finish. The final SHS products are cut to length and optionally coated to prevent corrosion, ensuring reliability for structural and fabrication applications.
SHS vs RHS
| Aspect | SHS (Square) | RHS (Rectangular) |
|---|---|---|
| Shape | Perfect square profile | Rectangular profile |
| Load Distribution | Uniform in all directions | Directional |
| Best Use | Frames, structures, fabrication | Beams, columns, long spans |
| Welding | Easier on all sides | More weld area required |
