High Speed Guardrail Anti Crash Barrier

Product description

High Speed Guardrail Anti Crash barrier , 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 "High Speed Guardrail Anti Crash barrier  / W-shaped steel / collision guardrail / traffic guardrail / highway guardrail / high speed guardrail / High Speed Guardrail Anti Crash barrier / traffic guardrail / column / barrier

The Hot Dipped Galvanized Process：

The main process of galvanizing corrugated guardrail is hot-dip galvanizing. The principle is that the melting points of steel and zinc are relatively different. The melting point of pure iron is 1534°C, and the melting point of zinc is only 419°C, so that the treated strip steel can be directly immersed in molten zinc solution for galvanizing.

Hot-dip galvanizing process: pickling of metal components-cleaning-adding auxiliary plating solution-drying-hot-dip galvanizing-cooling-passivation-cleaning-polishing-hot-dip galvanizing completion. The hot-dip zinc layer is formed by zinc in liquid state in three processes. The surface of the iron base is dissolved by the zinc liquid to form a zinc-iron alloy phase layer; the zinc ions in the alloy layer further disperse to the substrate to form a zinc-iron mutual-soluble layer; the alloy layer The surface is covered with zinc layer.
