The Types and Characteristics of Color Coated Substrates

As the most widely used roofing plate, the choice of the substrate also has a great impact on its functional effect. Under normal circumstances, the color coated substrate types are divided into three categories: hot-dip zinc substrate sheet, hot-dip aluminum and zinc substrate sheet, cold rolling sheet.

1.Hot dip zinc substrate sheet
Hot-dip galvanized sheet is hot rolled galvanized sheet, its zinc layer is thicker, suitable for preparation of high corrosion resistance, decorative requirements are not too high color coated sheet. Commonly used for exterior wall panels, roofing panels, garage doors, etc.

2.Hot dip aluminum and zinc substrate sheet
Hot aluminum zinc steel sheet is a variety of strength and thickness of cold-rolled steel sheet as the substrate, continuous heat filter core production line, by the aluminum core alloy coating. The production process of hot galvanized steel plate is basically the same as hot galvanized steel plate, which mainly regulates the composition of molten plating solution and is classified according to the content of aluminum. As a result of their good corrosion resistance and processing, has begun to replace the hot galvanized sheet. Commonly used for outdoor surroundings with heavy corrosion.

3.Cold rolling sheet
Cold rolling is made of a hot-rolled coil, which is rolled under recrystallization temperature at room temperature. Cold rolled steel plate is made by cold rolling process. Cold rolled steel plate thickness is more accurate, and the surface is smooth, beautiful. Although its cost is low, its anti-corrosion is poor compared with the other two. It is often used for lining parts of metal furniture, lamps, cable boxes and so on.
