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. HDG has a 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, both in the interior fittings depression, or any other coating is difficult to enter the corner trench cover capacity, are easily dissolved zinc uniform coverage on. 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, 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, or at a particular severe corrosive environments, paint over galvanized layer can handle duplex system Zaishi trench cover age, 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.

Press the flat direction trench cover bearing (support) direction, given the gap left by the groove width flat length L; 2. steel grating covers according to ditch long layout, taking in line with processing modulus The standard plate width 995mm, leaving a gap between the plates 5mm; 3. Ditch the remaining less than one meter long section modulus given by size; 4. selected according to the requirements of the groove width and bearing steel grating models. Air Products Co., Ltd.
