Hot dip galvanizing is mainly used to protect the substrate below the zinc layer, so that it from or less erosion, delay the application of pre-buried hot dip galvanized steel pipe life, its anti-erosion reasoning has the following aspects; zinc layer surface will produce a thin and dense layer of zinc oxide, it is difficult to dissolve in water, so the inside of the metal zinc layer plays a certain protective effect. Pre-embedded hot dip galvanized steel pipe kneading deformation course: guardrail plate is divided into two-wave guardrail plate, three-wave guardrail plate and two-wave three-wave transition plate, pre-embedded hot dip galvanized steel pipe reflection is also particularly important in the usual detection of a hollow workpiece, thin plate, angle and the same workpiece often need to be stored after hot dip galvanizing.
