ppgi ppgl ral pre painted color steel sheet metal manufacturing

1. Prepainted Steel Coil is coated with organic layer, which provides higher anti-corrosion property and a ppgi ppgl ral pre painted color steel sheet metal manufacturing lifespan than that of galvanized steel sheets.

2. The base metals for Prepainted Steel Coil consist of cold rolled, HDG electro-galvanized and hot-dip alu-zinc coated steel. The finish coats of Prepainted Steel Coil can be classified into groups as follows: polyester, silicon modified polyesters, polyvinylidene fluoride, high-durability polyester, etc.

3. The production process has evolved from one-coating-and-one-baking to double-coating-and-double-baking, and even three-coating-and-three-baking.

Units on a continuous cold-rolled strip steel or steel sheet,galvanized steel (electro galvanized,Pre-painted steel coil hot galvanized,Galvalume and cold-rolled plate) as the substrate, after surface preparation (degreasing and chemical treatment), ppgi ppgl ral pre painted color steel sheet metal manufacturing by a roll coating method, applying one or more layers liquid coating, after baking and cooling the resulting sheet is coated steel.Pre-painted steel coil Since the coating can have a variety of colors, it is customary to coated steel is called color coated steel sheet (PPGI).

ppgi ppgl ral pre painted color steel sheet metal manufacturing is the material which uses galvanized steel as the basic substrate metal. PPGI is prepainted galvanized steel, also known as precoated steel, coil coated steel,Pre-painted steel coil color coated steel etc.ppgi ppgl ral pre painted color steel sheet metal manufacturing A galvanized steel sheet in coil form is cleaned, pretreated, applied with various layers of organic coatings which can be paints, vinyl dispersions, Pre-painted steel coil or laminates.ppgi ppgl ral pre painted color steel sheet metal manufacturing are applied in a continuous process known as Coil Coating.The steel thus produced in this process is a prepainted, prefinished ready to use material.
