SGCC plate with zinc surface
SGCC plate with zinc surface.Galvanizing or galvanizing is the process of applying a protective zinc coating to steel or iron to prevent rust. The most common method is hot dip galvanization, in which parts are dipped in a bath of molten zinc.
Hot dip galvanized layer is a thick and strong layer of zinc - iron alloy. In the case of an automobile body, additional decorative paint will be applied, and electric galvanizing will take a thinner form of galvanizing.
The hot dip process does not generally reduce strength in a measurable range, and hydrogen embrittlement may be a problem with the exception of high-strength steels (>1100 MPa). This defect is a consideration that affects the manufacture of wire ropes and other high-stress products.
The protection provided by hot-dip galvanizing is insufficient for products that are often exposed to corrosive substances, such as acid rain. For these applications, more expensive stainless steel is preferred. Some of the nails are galvanized today. However, many outdoor applications use electroplating because it is cheaper than hot-dip zinc coatings and looks good in new conditions.
SECC= electrogalvanized steel plate: fingerprint resistance, excellent corrosion resistance, and maintain the processing of cold rolled plate. USES: electrical appliances, computer housing and some door panels.
Galvanized steel plate is to prevent the surface of steel plate corrosion to extend its service life, coated with a layer of metal zinc on the surface of steel plate, this kind of galvanized steel plate is called galvanized plate.
SGCC plate with zinc surface.Hot dip galvanized steel plate. A sheet of steel coated with zinc that is immersed in a molten zinc bath. At present, the main use of continuous galvanized production process, that is to roll the steel continuous dip in the molten zinc plating bath made of galvanized steel.
Never be afraid to bother me, it is no matter if you have the regular supplier, just take a consideration while our products are the best price and high quality.
