What is the role of the galvanized layer of hot-dip galvanized steel guardrail?


The main function of the galvanized layer is to isolate the direct contact of the air with the body of the guardrail and reduce the rate of oxidation. For metal guardrails, if the material is not properly selected, it will rust quickly. The substrate of the hot-dip galvanized guardrail is hot-dip galvanized because the hot-dip galvanized zinc layer is the basic source of rust prevention.


What is the role of the galvanized layer of hot-dip galvanized steel guardrail?

The hot-dip galvanized layer is obtained by reacting a molten metal with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing has the advantages of uniform plating, strong adhesion and long service life.
