Road crash guardrail maintenance

There are three main methods for repairing crash barriers: brushed silver powder, hot dip galvanized, and hot dip aluminized.

1. Brush the silver powder. It is not very good from the actual anti-corrosion effect. Generally, it is affected by natural conditions and has a short service life. Generally, it can only be maintained for two to three years.

 

2. Hot dip galvanizing. What are the advantages and disadvantages of the guardrail? The purpose of using the hot-dip fence on the highway is to use the zinc layer to protect the underlying corrugated fence body from the outside air and moisture, thus ensuring the wave barrier. The body is protected from corrosion by related natural conditions, thereby extending the life of the wave barrier.
