1. The fence is made of high-quality Q195 or Q235 high-strength low-carbon steel, and is made of hot-dip galvanized steel strips in various specifications. It uses high-end high-frequency welding technology to ensure that the welds are flat and strong.

2. The zinc content on the surface of zinc-coated steel pipes reaches 60-80g/㎡, and they can remain rust-free for 3-5 years at room temperature.

3. Zinc-coated steel products are made by further processing galvanized pipes. The zinc-coated steel fence manufacturing process includes: machining → chemical treatment (degreasing → descaling → nano-ceramic coating → passivation) → electrostatic spraying (→ curing at 220°C for enamel-like finish). After these multiple processes, it can achieve a rust-free lifespan of up to 20 years.
