40mm X 40mm Hot Dip Galvanized Steel Square Tube

40mm x 40mm Hot-Dip Galvanized Square Tube is a high-strength, precision-engineered structural steel profile designed for superior durability and exceptional corrosion resistance. Manufactured from robust low-carbon steel and protected by a thick, metallurgically-bonded zinc coating, this Square Hollow Section (SHS) is the ideal solution for construction frameworks, industrial supports, agricultural projects, and commercial applications. It offers an excellent strength-to-weight ratio, a clean finished appearance, and a long, maintenance-free service life, even in harsh environments.

Superior Corrosion Protection: The hot-dip galvanizing process ensures a complete, uniform zinc coating that provides a robust barrier against rust, oxidation, and moisture, significantly extending the product's lifespan outdoors.

High Structural Strength: The square cross-section offers excellent load-bearing capacity and resistance to torsional and bending forces, making it perfect for frames, supports, and structures.

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

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

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

Ready-to-Use Finish: The attractive, spangled zinc finish is clean and often requires no further painting or surface treatment, saving time and cost.

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

Industrial & Manufacturing: 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.

Quality Assurance: Strict quality control from raw material to final product. Mill test certificates (MTC) 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.

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 1-3 tons, but we can accommodate smaller trial orders. Please inquire for details.
