The substrate of color steel plate is cold rolled substrate, galvanized substrate and zinc plated substrate. The types of coatings can be divided into polyester, silicon modified polyester, two fluoroethylene and plastic sols. The surface state of color plate can be divided into coating board, embossing board and printing plate. Color plate is widely used in building electrical appliances, transportation and other industries. The construction industry is mainly used for roof walls and doors of industrial and commercial buildings such as steel structures, airports, storehouses and freezing, and the use of color steel plates is less for civil buildings.

Difference between folding and plastic steel

With the plastic material difference is different, magnet can suck move. In strict sense, the plastic and color steel can not be distinguished well on the metal characteristics and surface treatment, because the difference is very similar, so the market is distinguished mainly in the profile structure.

Folding test magnet as is common carbon steel, magnet can suck. On the other hand, stainless steel is added on the basis of low carbon steel to add the product after chromium element (greater than or equal to 13%), so the magnet can not suck.
