Early guardrail Set in the open air, wind, sun, rain, etc. will rust and fall off soon. At present, many fitness equipment installed on the roadside and in small parks basically use powder paint. If it is not for the bumps caused by the falling off of the coating, the anti-corrosion effect is much better than that of the coating, which only needs to be sprayed once. Therefore, the performance of outdoor powder coating for highway guardrails is better than that of paint coating.
Highway guardrails, isolation fences, etc. are all made of yellow and black spacers. In the past, rust primer was sprayed before painting, and later maintenance is to directly brush the surface paint with a brush.
