High Strength 40x40mm GI Square Pipe

40mm x 40mm Galvanized Square Tube is a premium structural steel profile designed for superior strength and exceptional corrosion resistance. Manufactured from high-quality steel and protected through a rigorous hot-dip galvanizing process, this square hollow section (SHS) is the ideal choice for demanding construction, industrial, agricultural, and DIY projects. It offers an excellent strength-to-weight ratio, a clean, finished appearance, and long-lasting durability even in harsh environments.

Exceptional Corrosion Resistance: The hot-dip galvanized zinc coating provides a robust barrier against rust, oxidation, and moisture, significantly extending the product's lifespan outdoors and in humid conditions.

High Structural Strength: The square shape offers excellent load-bearing capacity and resistance to bending from multiple axes, making it perfect for frames, supports, and structures.

Durable & Long-Lasting: Built to withstand wear, impact, and the elements, reducing maintenance needs and replacement costs over time.

Clean & Ready-to-Use: The galvanized finish provides a neat, aesthetically pleasing look that often requires no further painting or surface treatment.

Ease of Fabrication: Can be easily cut, drilled, welded (with proper techniques), and assembled using standard metalworking tools.

Versatile Application: Suitable for a vast range of projects, from heavy-duty industrial frameworks to decorative residential items.

Packaging: Bundles are securely strapped with steel or plastic straps. Ends are protected with caps to prevent damage. For international shipping, bundles are mounted on a wooden pallet and can be wrapped in waterproof paper or plastic for maximum protection.

Shipping: We have extensive experience in exporting worldwide. Products can be shipped via sea freight (FCL/LCL), air freight, or by express courier for smaller samples.

Quality Assurance: Strict quality control from raw material to final product. Mill test certificates available upon request.

Competitive Pricing: Factory-direct pricing due to large-scale production and efficient operations.

Customization: We can customize wall thickness, length, zinc coating weight, and bundle size to meet your specific project requirements.

Reliable Supply: Large inventory ensures consistent supply and on-time delivery for both small and bulk orders.

Expert Support: Our technical sales team can assist you with product selection and specifications.

Construction: Structural frameworks, support columns, roof trusses, purlins, fence posts, gate frames, handrails, and balustrades.

Industrial: Machine guards, workbenches, conveyor system frames, storage racking, equipment supports, and warehouse shelving.

Agricultural: Greenhouse structures, livestock pens, equipment frames, irrigation systems, and barn supports.

Commercial & Residential: Outdoor furniture (frames for tables, chairs), swing sets, playground equipment, canopy frames, and DIY projects.

Decoration: Modern furniture design, retail display units, art installations, and signposts.

Q: Can this square tube be welded?

A: Yes, but it requires specific techniques. The zinc coating must be removed from the area to be welded first, as welding galvanized steel can release harmful fumes and affect weld quality. Always weld in a well-ventilated area using proper safety equipment.

Q: What is the difference between hot-dip galvanized and electroplated?

A: Hot-dip galvanizing provides a much thicker, more durable, and longer-lasting zinc coating compared to electroplating (which is thinner and primarily for cosmetic protection). Our hot-dip process is ideal for outdoor and structural use.

Q: Do you provide samples?

A: Yes, we are happy to provide small samples for quality verification. Please contact us for sample details.

Q: What is your MOQ (Minimum Order Quantity)?

A: Our MOQ is typically 1 ton, but we can accommodate smaller trial orders. Please inquire for details.
