A: A galvanised steel square tube is a hollow, square-shaped steel tube coated with a protective zinc layer through hot-dip galvanisation. This process prevents rust and corrosion, making it ideal for outdoor and industrial use.
A: Galvanised square tubes are widely used in construction, fencing, handrails, and structural frameworks. Their durability and resistance to harsh weather make them suitable for both residential and commercial projects.
A: The zinc coating acts as a barrier against moisture and environmental elements, preventing oxidation. This significantly extends the tube's lifespan compared to non-galvanised alternatives.
A: Yes, galvanised tubes can be welded or cut, but the exposed areas should be treated with zinc-rich paint to maintain corrosion resistance. Professional handling is recommended to preserve the protective layer.
A: Consider load requirements, wall thickness, and project dimensions. Standard sizes range from 1x1 inch to 6x6 inches, with varying gauges to suit structural needs.
