MS GI rectangular and square hollow section steel pipes are manufactured with premium-grade mild steel and galvanized for superior anti-corrosion performance. The uniform zinc coating offers long-term resistance to rust and weathering, making these pipes ideal for structural, decorative, and industrial use.

The product comes in standard sizes such as 80×40mm and 120×60mm, with thickness options ranging from 0.8mm to 12mm. Each pipe undergoes strict dimensional inspection, mechanical testing, and coating thickness verification to ensure compliance with ASTM, EN, and GB standards.

Galvanized hollow section steel pipes are characterized by smooth surfaces, easy weldability, and high tensile strength, suitable for load-bearing structures, furniture frames, scaffolding systems, greenhouse construction, and industrial machinery. The zinc coating layer provides both protection and a bright metallic finish.

Available in both pre-galvanized and hot-dip galvanized options, the pipes can be cut to any custom length. Standard supply lengths are 6 meters and 12 meters. Our factory ensures tight dimensional tolerances and excellent coating adhesion for long-lasting performance even in humid or outdoor environments.

All products are packed with waterproof paper, plastic film, and steel straps to ensure safety during shipping. Factory direct supply guarantees competitive pricing, flexible OEM customization, and global export service. These GI rectangular and square hollow steel tubes are a durable, economical, and versatile solution for construction and industrial applications.
