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
