Product Details

Product Description

Highway Guardrail Systems is a longitudinal, roadside barrier system that is installed to prevent errant vehicles from impacting roadside obstacles. By redirecting a vehicle departing the roadway, a guardrail keeps it away from more serious hazards, both constructed (e.g., sign structures, culvert inlets, utility poles) and natural (e.g., trees, rock outcrop). Guardrail prevents vehicles from descending a steep roadside embankment or veering into the roadway median and oncoming traffic. In some cases,Highway Guardrail Systems is installed for reasons other than to safeguard motorists against obstacles (e.g., road closure barricades and barriers protecting pedestrians or sensitive areas).

Production Flow

Process differences Hot-dip galvanizing process: pickling of products - cleaning - adding auxiliary plating solution - drying - hot-dip galvanizing - cooling - passivation - cleaning - grinding - 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.
