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), Pre-painted Galvanized Steel Coil 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).

Pre-painted Galvanized Steel Coil 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.Pre-painted Galvanized Steel Coil 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.Pre-painted Galvanized Steel Coil 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.
