Road Guard Rail

Product description

Galvanized highway guardrail , refers to the corrugated steel guardrail spliced with each other and supported by the main column of the continuous structure. In the vehicle collision on its role in absorbing energy is not easy to be destroyed, but also to protect the vehicle and passengers. Often referred to as "highway guardrail / W-shaped steel / collision guardrail / guardrail / traffic guardrail / highway guardrail / high speed guardrail / industrial guardrail / traffic guardrail / column / barrier"

Influence of hot-dip galvanizing process on the appearance of guardrail

1. When the galvanized guardrail is galvanized, if the residual moisture contains chlorides, sulfides in the industrial environment, or the zinc content in the galvanizing is too high, the galvanizing solution should be replaced or the temperature should be lowered, and salvaged Zinc slag, this is to prevent the zinc particles from being too dense. However, due to reasons such as the hot-dip galvanizing process and cost control, a small amount of zinc particles is unavoidable.

2. Rough surface of galvanized: When the iron-zinc alloy is formed too much or unevenly distributed, the surface will be rough. And there may be a little white rust on the surface. The guardrail with white rust will make people feel severely corroded. The white powder is not rusted on the zinc layer, and it only needs to be wiped and treated with weak acid. This kind of white rust is caused by the rapid formation of iron-zinc alloy due to the high temperature. The time of galvanizing is relatively long, which increases the diffusion reaction of iron and zinc.

During the process of transportation, loading and unloading, the guardrail materials inevitably produce scratches. From the characteristics of hot-dip galvanizing, we can know that the color difference between zinc and iron is relatively obvious, but the anodic protection of the zinc layer The characteristics will protect the surface from slight scratches, and the scratches can be treated with zinc-rich paint.
