Frequently asked questions

Square tubes offer flat surfaces that are easier to bolt, weld, and connect to plates or other components, making them the preferred choice for structural frameworks, racks, and fencing. They also provide a more modern and neat aesthetic appearance.

Yes. As a factory, we specialize in custom orders. We can produce square tubes in non-standard dimensions (like 55x55mm) and adjust wall thickness according to your structural calculations. Please provide your detailed requirements.

We use the full-immersion hot-dip process. The entire welded square tube is dipped vertically into the zinc bath, allowing the molten zinc to flow and cover all inner surfaces and corners uniformly. This is a key advantage over electro-galvanizing.

Absolutely. They are one of the most popular materials for fence posts. The square shape provides greater stability in the ground and makes it easier to attach fence panels. The hot-dip galvanizing ensure

We adhere to strict ASTM A500 tolerance standards: Straightness tolerance is within 1.5mm per meter, and the outside dimensions (width/height) tolerance is within ±0.5%. This ensures perfect alignment during your construction.
