Hot Galvanized Shandong Color Coated Sheet Longer Service Life


Why hot-dip galvanized Shandong color coated sheet has a long service life? This is inseparable from its special production process. Generally, the product obtained by coating the organic coating on the hot-dip galvanized steel plate is the hot-dip galvanized color-coated plate. This color coated plate not only has the protective effect of zinc, because of its surface and a layer of organic coating, but also play a role in isolation and protection, to prevent rust, so the service life is longer than the heat of the new plate. The zinc content of the hot-dip galvanized substrate is generally 180g/m2 (double-sided), and the galvanized amount of the hot-dip galvanized substrate for the exterior of the building is 275g/m2. With the upgrading of domestic users' demand for the quality of color coated plates and the increase of market pressure, a large number of low-level color coating units will be gradually eliminated, and high-level color coating units will occupy more market share, which will be conducive to the improvement of the overall quality of the domestic color coating industry.
