The use of hot dip galvanized fence more widely, it has what features and functions? Less to find out more. 1, because they face a galvanized fence thicker galvanized layer, so it can not be subject to any erosion protection fence corrosive substances. 2, iron and zinc binding is very strong, very abrasion. 3, a good extension of zinc, an alloy layer is firmly attached to the base steel, so that various processing will not damage the coating 4, the structure of the object just after the hot-dip galvanized steel can effectively improve the mechanical properties of the matrix, conducive to turning on the steel structures. 5, after the object has galvanized guardrail face looking bright. Many spray fence surface treatment, should be a reasonable choice based on the actual situation. Can be considered from several aspects of selection. 1, the degree of contamination and the formation of pollutants such as oil to the upper surface of the spray rails little more cold rolled steel sheet and corrosion, the surface treatment is focused on the removal of grease. Degreasing and cleaning can be carried out without rust treatment. If the oil spray rails on the primary saponification reaction is to occur should be selected with a strong base cleaning agent as a main component, making it happen saponification reaction is removed; if oil is the main component of the saponification reaction can not occur in mineral of oil, the surfactant should be selected having as a wetting and dispersing emulsifying cleaning agent, it is emulsified and dispersed from the surface of the spray rails. 2 in, spray painting the fence rails in the future if the environment is to be used in the harsh natural environment, as often subjected to extreme temperature changes, intense sunlight, rain and dust storms and other natural conditions, the resistance of the coating high corrosion resistance requirements, it should be cleaned, phosphating, passivation and other multi-step treatment process guardrail, fence spray to improve protection performance in order to improve the corrosion resistance of the coating; while the spray rails for indoor use roads requirements fence, pre-treatment generally low, the choice of technology is also relatively simple. 3, the coating properties of the coating composition of the type with different adhesion spray rails, pre-treatment with different requirements. Such as perchlorethylene coatings, silicone spray paint on steel rails adhesion is poor, it is necessary to conduct a more rigorous pre-treatment pvc fence, especially oil thoroughly, otherwise the entire coating is easy to fall off. The epoxy primer, polyurethane primer and spray rails and other strong binding force, because these primer pre-treatment requirements for low, even spray paint on a fence in the rust belt of semi-finished products directly.
