Hot Galvanized Highway Guardrail

A principle of hot dipped galvanized: galvanized iron to clean clean, then solvent treatment, drying after immersed in liquid zinc, iron and zinc layer of molten zinc reaction produce an alloying, the process for degreasing, washing, pickling, helps the plating - drying - hot dip galvanized, separation, cooling passivation.

The advantage of Hot Galvanized Highway Guardrail:

1. Durable: in the suburbs, the standard hot-dip galvanized rust resistance can be kept for more than 50 years without having to be repaired; In urban or offshore areas, the standard hot-dip galvanized coatings can be kept for 20 years without having to be repaired;

2. Good reliability: the zinc coating and steel are metallurgical bonding, which is a part of the steel surface, so the durability of the coating is more reliable.

3. The coating has a strong toughness: the zinc coating forms a special metallurgical structure, which can withstand mechanical damage when transported and used.

4. Comprehensive protection: every part of the plating can be plated with zinc, which can be fully protected even in the depression, sharp corners and hiding places.

The test is simple and convenient: the hot-dip zinc coating can be visualized and simple non-destructive coating thickness meter for testing.
