Product Overview

Galvanized Square/Rectangular Steel Pipe, including SHS (Square Hollow Section) and RHS (Rectangular Hollow Section), is a galvanized hollow structural steel product designed for construction, fabrication, and outdoor engineering applications. It provides a practical solution for projects requiring stable structural performance, dimensional accuracy, and improved corrosion resistance.

Manufactured according to international standards including GB/T 6728, EN 10219-1/2, ASTM A500 Grade B/C and ISO 1461, this product supports multiple steel grades such as Q195, Q235B, Q355B, S235JR, S275JR, S355JR, ASTM A500 Grade B/C, STKR400 and STKR490 to meet different project requirements worldwide.

The product covers a wide dimensional range. Square hollow sections are available from 10×10mm to 500×500mm, while rectangular hollow sections range from 20×10mm to 600×400mm, with wall thickness options from 0.8mm to 16mm. Standard lengths include 6m and 12m, with customized cutting available from 1m to 12m.

Galvanized Square/Rectangular Steel Pipe is widely used in steel structure buildings, photovoltaic support systems, fences, container frames, agricultural greenhouses, equipment bases, warehouse structures, and decorative engineering projects. It is suitable for steel fabricators, EPC contractors, solar system installers, fence manufacturers, and industrial construction companies.
