Real prepainted galvanized steel coil
PPGI/PPGL(prepainted galvanized steel /prepainted galvalume steel )is also known as pre-coated steel,color coated steel, coil coated steel, color coated steel,pre pianted steel sheet,The PPGI steel coil/sheet made of cold-rolled steel sheet and galvanized steel sheet, subjected to surface pretreatment (degreasing, cleaning, chemical conversion treatment), coated in a continuous manner, and baked and cooled to form a product. Coated steel has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed. It provides a new type of raw materials for the construction industry, shipbuilding industry, vehicle manufacturing industry, home appliance industry, electrical industry, etc.

Production Process
1. Cold rolled substrate color coated steel sheet
The color sheet produced by the cold-rolled substrate has a smooth and beautiful appearance and has the processing property of the cold-rolled sheet;
2. Hot-dip galvanized color coated steel sheet(prepainted galvanized steel sheet)
The product obtained by coating an organic coating on a hot-dip galvanized steel sheet is a hot-dip galvanized color-coated plate. In addition to the protective effect of zinc, the hot-dip galvanized color-coated sheet also protects against rust and has a longer service life than hot-dip galvanized sheet;
3. Hot-dip aluminum-zinc color coated sheet(prepainted galvalume steel sheet)
Hot-dip aluminum-zinc steel sheets can also be used as color-coated substrates (55% AI-Zn and 5% AI-Zn);
4. Electroplated zinc color coated sheet
The electro-galvanized sheet is used as the substrate, and the product obtained by baking with the organic coating is an electrogalvanized color-coated plate. It has a beautiful appearance and excellent processing properties, and therefore can be mainly used for home appliances, audio, steel furniture, interior decoration, and the like.
Main Features
1.Anticorrosive:13 years in heavy industrial areas, 50 years in the ocean, 104 years in the suburbs and 30 years in cities.
2.Cheap:The cost of hot-dip galvanizing is lower than that of other
3.Reliable :The zinc coating is metallurgically bonded to the steel and forms part of the steel surface, so the coating is more durable.
4.Strong toughness:The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and
5.Comprehensive protection:Every part of the plated piece can be galvanized, and is fully protected even in depressions, sharp corners, and hidden places.
6.Save time and energy:Galvanizing process is faster than other coating methods.
