The difference between hot dip galvanized and cold galvanized steel grating: galvanized steel grating is the first pickling steel grating, steel grating in order to remove the iron oxide surface, pickled, by ammonium chloride zinc mixed aqueous solution tank for cleaning, and then melted into the hot dip zinc plating bath. Galvanized zinc coating with a uniform coating of galvanized steel grating, strong adhesion, long life, life of up to 40 years. Cold galvanized steel grating is also the country pickling steel grating galvanized steel grating, but is made of zinc electrolytic cold galvanized steel grating has a disadvantage in the electrolytic galvanized steel grating when using linked plating, and so the entire piece of steel grating coated steel grating After sealing the bottom because of excessive current is burned black, still need final spray silver paint. Grating commonly used carbon steel, galvanized exterior, can serve to prevent oxidation. Can also be made of stainless steel. Steel grating with ventilation, lighting, cooling, slip-proof properties. Steel grating made of flat steel and bars with certain arrangement of latitude grid spacing by the load flat steel, namely the length direction of the steel grating; zonal for rail, namely the width direction of the steel grating.
