Product Introduction
Non-Alloy Hot-DIP Galvanized Steel Tube
Galvanized Square Pipe

Our Hot-dip Galvanized Square Steel Pipe is a premium carbon steel product designed for structural applications. Manufactured from high-grade non-alloy carbon steel, including grades such as S195jr, S235jr, and S355jr, this pipe provides exceptional load-bearing capacity and durability for demanding structural environments.

With a specification range of 15-1000mm and thicknesses from 1.5mm to 30mm, our products adhere to strict industry standards. The professional hot-dip galvanizing process enhances corrosion resistance, making it ideal for outdoor and humid settings. We also provide customized cutting, welding, and bending services.

These versatile pipes are suitable for building structures, curtain wall supports, steel workshops, and logistics shelving. With an annual output of 400,000 tons, we ensure a reliable supply chain and prompt delivery for large-scale projects. We utilize standard export packaging to ensure products arrive safely via bulk or container shipment.

Frequently Asked Questions
1. What are the primary applications of hot-dip galvanized steel pipes?
Hot-dip galvanized steel pipes are widely used in curtain walls, power transmission towers, communication grids, and industrial workshops. Their excellent durability makes them a preferred choice for reliable structural performance.
2. What are the acceptance criteria for these steel pipes?
Quality is judged by checking appearance for defects like missing plating or bubbles. A consistent, defect-free surface ensures the product is qualified for high-standard engineering projects.
3. Why might galvanized steel pipes show signs of rust?
Zinc is chemically active and can react in humid or acidic environments. If the zinc coating is compromised or exposed to hydrogen sulfide, corrosion resistance decreases. Specialized phosphating treatments can be used to further inhibit rust formation.
4. How do you prevent cracking when welding in low temperatures?
We recommend using low-hydrogen welding materials and preheating the steel to 80-200℃. Symmetric welding and slow cooling for at least 2 hours post-welding help minimize stress and avoid cracks.
5. What size and thickness ranges are available?
We offer a wide range of specifications from 15mm to 1000mm in section shape, with thicknesses ranging from 1.5mm to 30mm to meet diverse load-bearing requirements.
6. What is the standard delivery timeline for orders?
Our standard delivery time ranges from 5 to 25 days, depending on the order volume and customization requirements, supported by an annual production capacity of 400,000 tons.
