What is the reason and method of surface treatment of high-speed guardrail board?

We see a lot of high speed on the highway guardrail plate is specially technology to make the processed, it is have a lot of shiny surface, malleable, there are all sorts of durable performance, such as collision avoidance in the various protection is relatively large, is also good, so if the guardrail plate usage is big, this is it for the reasons of surface treatment and benefits. Therefore, after the completion of production and processing, it is necessary to deal with it professionally.

(1) screen protection

When the cold spray zinc paint is oxygenated, a layer of zinc salt will be formed on the surface of the paint to provide the best care of the barrier. At the same time, the adhesive in the cold spray zinc paint also provides an additional barrier to take care of, thus reducing zinc oxygenation. So the corrosion resistance of cold spray zinc paint is better than spray zinc (aluminum), hot dip galvanizing and other zinc rich paint.

(2) Cathodic protection

Cold spray zinc is different from ordinary paint film, its dry film includes more than 96% pure zinc, can provide good negative electrode for steel to take care of. Even in a very mean background, he has long tried to take care of his steel appearance. Anti-corrosion properties can be compared with hot dip galvanizing, or even better than hot dip galvanizing.

High-speed guardrail plate for highway anti-collision facilities, by two corrugated beam steel guardrail plate and two fixed clamp between the guardrail column. Its main purpose is to prevent out of control vehicles out of the road, according to the different highway grade and adopt different specifications. In THE normal operation of the highway, the GUARDRail can be easily inserted into the pre-set insertion hole at the opening by using the plug and pull steel column, which plays the role of isolation and protection, and echoes the guardrail belt outside the highway, neat and uniform, beautiful matching.
