Fence, metal fence Sau Wai series, Iron rails provided by Sau Wai metals. Fence | Sau Wai metal guardrail Series | zinc steel fence is Linqu show Wei Metal (www.xiuweijinshu.com) 2014 upgrade been newly introduced below tell you about the advantages of spray rails: 1, Surface treatment: spray plastic layers, never rust. Ie: After four and nineteen special chemical coating chemical treatment process, resulting in permanent coating, smooth good, it has excellent corrosion resistance, anti-UV, anti-shock and anti-dirty performance, long service life. 2 new colors: CPT launch cross freely mix different colors, and plants, office buildings, doors, residential balcony, villas, hospitals, schools, parks, roads, tourist attractions and the environment against the background, perfect overall effect. 3, environmental protection: will not rust In any harsh environment, fading, cracking, weathering, aging, loss, and good self-cleaning properties of the surface, rainwater naturally flush Province provincial costs saving time, forever beautiful as new landscaping. 4 security: As a result of super-hardness steel, installation, embedded piles, and plug-in connections, no welding, anti-theft screws, the whole firm, firm will not break easily damaged, vertical column spacing is only 10cm, density large, can not drill more. Here to tell you about selective surface treatment spray rails principles: 1 degree form and pollution contaminants such as spray rails on the surface of the oil and corrosion little more than cold-rolled steel, the surface treatment is focused on removing 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 different coating properties of the coating composition, and the binding force of different spray rails, pre-treatment requirements are also different. Such as perchlorethylene coatings, silicone spray paint on steel rails adhesion is poor, it is necessary to conduct a more rigorous pre-treatment wrought iron 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. Effect. Spray spray fence fence fence in the future use of the environment if the spray 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 coating The high corrosion resistance of the film is required, it should be cleaned, phosphating and passivation multi-step process, to improve the protection performance of the spray rails to improve the corrosion resistance of the coating; while for indoor use in the spray requirements fence, pre-treatment generally low, the choice of technology is also relatively simple.
