Square & Rectangular Hollow Structural Sections (SHS/RHS)

Steel hollow sections are essential components in modern engineering, primarily categorized into round, rectangular, and square profiles. Our Square Hollow Sections (SHS) and Rectangular Hollow Sections (RHS) are high-strength carbon steel tubes widely utilized in construction, engineering, and industrial applications.

Available in both black and galvanized finishes, our structural tubes offer exceptional load-bearing capacity and durability. Galvanized treatments significantly enhance the material’s resistance to corrosion, rust, and acids, effectively extending the service life for demanding outdoor projects like fencing and greenhouses.

Frequently Asked Questions (FAQ)

Q: What are the differences between SHS and RHS in structural use?
A: SHS (Square Hollow Sections) provide symmetrical strength, ideal for columns and posts. RHS (Rectangular Hollow Sections) are often preferred for beams and architectural aesthetics where depth provides extra resistance to bending.

A: Yes. We manufacture strictly according to EN 10210/EN 10219 (European), ASTM A500 (American), and GB/T 3094 (Chinese) to meet your regional engineering requirements.

A: Yes, besides galvanization, we offer professional painting in various colors to provide both anti-corrosion and aesthetic value for exposed structures.

A: Absolutely. With wall thicknesses up to 16mm and materials like S355, our hollow sections are designed for heavy-load structural applications.
