High Zinc Layer Galvanized Square Pipe Rectangular Tube for Curtain Wall Frame & Steel Structure Support

Our high zinc layer galvanized square and rectangular steel tubes are premium hot‑dipped galvanized steel hollow sections, widely used as core components for curtain wall frameworks and steel structure engineering. Manufactured with strict hot‑dip galvanizing technology, these steel pipes feature a thick high‑zinc coating layer, stable mechanical performance and precise dimensional tolerance. They are ideal structural materials for modern building curtain walls, steel structure supports, industrial construction and outdoor engineering, ensuring long‑term anti-corrosion, rust-proof and weather-resistant performance in complex construction environments.

High Zinc Layer Anti-Corrosion Performance:
Adopts heavy-duty hot-dip galvanizing process with thick zinc coating, effectively resisting rust, oxidation and corrosion, extending service life for outdoor curtain wall and steel structure projects.

High-Strength Structural Stability:
Made of high-quality carbon steel raw materials, with excellent tensile strength and bending resistance, stable structure, suitable for load-bearing support of steel structure and curtain wall frames.

Precise Size & Good Machinability:
Strict dimensional tolerance, smooth surface, easy for cutting, welding and installation, perfectly matching curtain wall and steel structure construction standards.

Weather-Resistant & Long Service Life:
Adaptable to high temperature, humidity, coastal salt fog and other harsh environments, ideal for long-term building curtain wall and steel structure use.

Standard Compliance & Customizable Service:
Conforms to international steel standards, supports customized sizes, zinc layer thickness and surface processing to meet personalized curtain wall and steel structure project needs.

Building Curtain Wall System:
Main frame and keel materials for glass curtain walls, aluminum curtain walls, external wall decorative curtain walls of commercial buildings, office buildings and high-rise buildings.

Steel Structure Engineering:
Steel structure support frames, load-bearing brackets, steel trusses for industrial plants, warehouse steel structures, prefabricated buildings and residential steel structures.

Outdoor Construction Projects:
Outdoor steel frames, fence structures, solar photovoltaic bracket steel structures, bridge auxiliary steel structures with high anti-corrosion requirements.

Architectural Decoration & Infrastructure:
