After the performance of hot dip galvanized fence has the following advantages. Cover layer thick, layered coating galvanized fence manufacturers, close to the workpiece inner galvanized guardrail, chemical composition containing a maximum workpiece components; close to the surface of the outer coating metal chemical composition containing up to. An intermediate layer between the inner and outer layer of the alloy. Alloy layer containing a small amount of the workpiece due to the inclusion of trace metals and therefore more brittle mechanical properties of the coating is very bad, its thickness should have control. Protection principle galvanized guardrail protection layer: galvanized steel fence to protect the principle reason why the protective layer of galvanized hot dip galvanized fence maintenance, because the zinc in corrosive environments can form on the surface of good corrosion resistance film. It not only protects the zinc layer itself, but also to protect the steel substrate. So galvanized guardrail process by galvanized steel after greatly extended service life. The life of the layer and the environment related to atmospheric corrosion test conducted on galvanized sheet, it can be confirmed that, in electrochemical corrosion refers to the metal and the gas influx ta conductive liquid medium, since the electronic Corrosion caused by the flow. For example, the corrosion of zinc and zinc occurred in acid, alkali, salt solution and sea water in moist air atmospheric corrosion, electrochemical corrosion belong.
