Characteristics of zinc steel guardrails

Jul 11, 2026

1. The zinc-steel base material is made of hot-dip galvanized steel strip, produced into various specifications of galvanized steel using advanced high-frequency welding technology, resulting in smooth and strong welds.

 

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

 

3. Zinc-steel products are further processed from galvanized pipes. The zinc-steel fence process includes: machining → chemical treatment (degreasing → descaling → nano-ceramic coating → passivation) → electrostatic spraying (→ curing at 220°C high temperature, imitation enamel curing). After multiple processes, it can achieve rust-free performance for up to 20 years.

 

4. The biggest feature of zinc-steel products is the absence of welding. Zinc-steel's custom-developed accessories perfectly integrate with the pipes, achieving a beautiful, sturdy, and practical finish, meeting the standards of the American Fence Association.

 

5. The product surface is powder-coated. Its products are aesthetically pleasing, with colors that can be freely combined, surpassing even the rainbow in vibrancy. They feature seamless, weld-free assembly, superior protective capabilities, self-cleaning properties, and environmental friendliness, achieving the true meaning of low-carbon, environmentally friendly, and green living products advocated by the state.
