Galvanizing treatment:
  Galvanizing is a common surface treatment of guardrail boards
Galvanizing is divided into hot galvanizing and cold galvanizing
Generally, hot galvanizing is used because the service life of hot galvanizing is longer than that of cold galvanizing, and the surface after galvanizing is silver white

  2
Plastic dipping treatment:
  Plastic impregnation is also the most common way of guardrail surface treatment
After its surface treatment, we can see the green and blue guardrail boards

  3
Galvanizing and plastic dipping treatment:
  Galvanizing and plastic dipping treatment is to do galvanizing surface treatment on the guardrail board first, and then do plastic dipping treatment on the premise of galvanizing treatment
The purpose of this is to improve the service life of the guardrail board and make the guardrail board more suitable for the harsh use environment
Generally, this surface treatment is more used in the cold northern areas
