Why trench cover galvanized popular trench cover surface treatment methods are: hot-dip galvanizing, painting, but in practical use galvanized trench cover the most widely used. HDG also known as hot-dip galvanized, is a method of steel components immersed in molten zinc liquid metal blanket obtained, the molten metal is galvanized iron reaction matrix alloy layer food processing steel grille ditch the cover plate, so that the substrate and coating combination of both. Has galvanized coating uniformity, strong adhesion, long life and other advantages. In recent years, with the high-voltage transmission, transportation, communications industry rapid development of increasingly high demand for steel parts protection, hot dip galvanizing demand is also increasing. Trench cover hot galvanized benefits: 1. the entire surface of the steel are protected, both in depression inside the pipe, or any other coating difficult to enter a corner, are readily solubilized zinc on the uniform coverage. 2. zinc coating hardness value is greater than steel, so the impact resistance and anti-wear properties are quite good. 3. High corrosion resistance, even if due to a lot of mechanical injury or other reasons, its product characteristics will protect steel from corrosion. 4. Coating life in a particular environment, mainly depending on the thickness of the coating. The coating thickness is determined also by the thickness of the steel, the thicker the steel easy to get a thicker coating plate trench cover grille covers specifications, so the same site of a steel plate in the thick thick coating must have been to ensure that to obtain a longer lifetime. 5. due to aesthetics, art stainless steel trench cover model, or when certain severe corrosive environments, zinc coating paint can handle more than Zaishi duplex system, as long as the selection of the correct paint system, easy construction, and its corrosion better than alone on paint and hot-dip zinc life together even better 1.5 to 2.5 times. Therefore steel with zinc coating to protect the most widely used, the best anti-corrosion effect and best value for money.
