Products Advantages
Superior Corrosion Resistance: The uniform zinc coating (hot-dip or electro) provides a protective barrier against rust, significantly extending the product's lifespan.
High Strength & Lightweight: Offers excellent structural support while being easy to handle, transport, and install, reducing overall project costs.
Easy to Fabricate: Can be easily cut, welded, drilled, and bent to meet specific design requirements. (Note: Welding burns off zinc; recoating is needed).
Clean & Aesthetic Finish: The smooth, silver-gray surface is visually appealing and provides a ready-to-paint base if a different color is desired.
Wide Availability: Available in various wall thicknesses (from 1.0mm to 2.0mm) to suit different load-bearing needs.

FAQ
Q1: Can these tubes be welded?
A: Yes, they can be welded. However, the extreme heat will burn off the zinc coating around the weld. To prevent rust, it is essential to apply a zinc-rich paint to the welded area after welding.
Q2: What is the difference between Hot-Dip and Electro-Galvanized?
A: Hot-Dip galvanizing creates a thicker, rougher coating that is much more durable and suitable for outdoor use. Electro-Galvanizing creates a thinner, smoother coating that is more aesthetic and suitable for indoor furniture or decorative items. Please specify your need.
Q3: What is the weight per meter?
A: The weight depends on the wall thickness. For example:
20x20mm x 1.0mm wall: ~0.60 kg/m
20x20mm x 1.5mm wall: ~0.87 kg/m
20x20mm x 2.0mm wall: ~1.12 kg/m
(We can provide a full weight chart).
Q4: Can I get custom sizes and lengths?
A: Yes. We offer custom cutting services to your specified length. Custom outer sizes and wall thicknesses are available for large quantity orders (e.g., MOQ 5-10 tons).
