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 matrix alloy layer produced by the reaction, so that the substrate and the coating II were combined. 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 using galvanized benefits: 1. The entire steel surfaces are protected, regardless of depression inside the tube steel grating trench cover underground garage, or any other coating is difficult to enter the corners are easily dissolved zinc evenly covered. 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 lifetime factory compound steel grating trench cover fixed 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, it is with a steel plate in the thick of the site must have been thicker coating, which guarantees a longer life. 5. due to aesthetics, art trench cover, 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 paint alone 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.
