prepainted galvanized steel coil brief introduction
Prepainted galvanized steel coil is a galvanized steel substrate that has had paint applied to both sides through a continuous paint coating line (CCL) where in the surface of the metal is cleaned, pre-treated and applied with various layers of organic coatings, which produces a uniform paint finish. The metal is unwound, cleaned and chemically treated during the process. Depending on product specifications, one or both sides may then be primed and coated, oven cured and rewound.It is also named color coated steel coil or PPGI, with a hot dip zinc coated steel sheet substrate.
Prepainted galvanized steel coil is made by processing the chemistry treatment (degrease, phosphorus and chromium hydrochloric acid passivation) on the surface of hot-dipped galvanized steel sheet, or zinc coated steel sheet, then drawing (the roller scribbles) the coating and baking.
prepainted galvanized steel coil advantages
Prepainted galvanized steel coil has the strength and easy shape-exchanging performance of the steel plate. It also has good adornment and anti-erode performance. And coating adhesive force is very strong.prepainted galvanized steel coil applications
