 The advantage of hot-galvanizing polyester coloring powder caoting combined guardrail
Handsome appearance
The guardrail is environment-friendly product in combination of PVC guardrail’s appearance. It color is brighter, more lustrous, more novel, and more handsome than that of PVC guardrail.
High dynamic resistance
Guardrail’s strength depends on good material. The guardrail uses special high-strength steel pipe, so its dynamic resistance reaches 2000kg impact force.
Long service life
Guardrail’s service life depends on good material and advanced manufacturing technique. It uses special heat galvanized steel pipe; after it is cleaned for several times, its surface is coated by imported USA polyester color powder; finally it uses packed structure. Compared with common same products in manufacturing technique, it can prolong service life (50 years at least). It realizes “Once Investment, Life Enjoyment.”
Weathering resistance, salt spray resistance, temperature resistance.
Whether it is in south or in north, the product can’t be influenced by temperature. In its salt spray resistance and temperature resistance, it has passed 3500h test without any obvious reaction, so the user may use it under various conditions for a long time.
Low maintenance cost
It uses advanced technical process. It can’t rust and fade. If it has dust after a long term, you may clean it by use of water plus cleanser essence. |
