Pre-painted coil is based on hot-dip galvalume sheet, hot-dip galvanized sheet, electro-galvanized sheet, and etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are applied on the surface, and then made by baking and curing. It is named after the colored steel coils coated with various colors of organic coatings, referred to as color-coated coils.

Color-coated coil substrates can be divided into hot-dip galvanized substrates, hot-dip galvalume substrates and electro-galvanized substrates.
The product obtained by applying an organic coating on a hot-dip galvanized steel sheet is a hot-dip galvanized color-coated sheet. In addition to the protective effect of zinc, the hot-dip galvanized color-coated sheet also has the function of insulating protection and preventing rust, and the service life is longer than that of the hot-dip galvanized sheet. The zinc content of the hot-dip galvanized substrate is generally 180g/m2 (double-sided), and the highest galvanized amount of the hot-dip galvanized substrate for building exterior is 275g/m2.
Hot-dip galvanized steel sheet (55% Al-Zn) is used as the newly coated substrate, usually containing 150g/m2 of aluminum and zinc (both sides). The corrosion resistance of hot-dip galvalume sheet is 2-5 times that of hot-dip galvanized sheet. Continuous or intermittent use at temperatures up to 490°C will not severely oxidize or produce scale. The ability to reflect heat and light is twice that of hot-dip galvanized steel, and the reflectivity greater than 0.75 is an ideal building material for saving energy.
The electro-galvanized sheet is used as the substrate, and the product obtained by coating with organic paint and baking is an electro-galvanized color-coated sheet. Since the zinc layer of the electro-galvanized sheet is thin, the zinc content is usually 20/20g/m2, so this product is not suitable for making walls, roofs, etc. However, because of its beautiful appearance and excellent processing performance, it is mainly used in home appliances, audio, steel furniture, interior decoration, etc.PPGI is a galvanized color-coated steel material, which is to carry out surface chemical treatment (degreasing, phosphating, chromium hydrochloric acid passivation) on the coated steel sheet (galvanized, galvanized, nickel-plated, etc.), then apply paint, and then bake to make products.
Advantages: It not only has the mechanical strength and easy formability of steel plate, but also has good decoration and corrosion resistance of organic materials. The coating has strong adhesion and can keep the color fresh for a long time.
Application: Widely used in various fields such as construction, home appliances, furniture, public facilities and transportation.
Paint
PPGI commonly paint is polyester(pe) and silicon modified polyester resin (SMP), High density polyethylene(HDP), PolyvinylideneFluoride(PVDF),and etc
Standard
America ASTM-A527(Galvanized steel), ASTM-AT92(Aluminum zinc steel), Japan JIS-g3302, EN0412, Korea KSD3506 and etc.
Paint Perf Ormance
Polyester PE:Good adhesion,in formability and outdoor durability aspect widely,with medium grade chemical resistance.Guarantee use 7-10 years.
Product Features
PPGI coil has high strength, fast-ness, goodrain resistance, continuous rolling, good corrosion resistance.It is easy to install
used in construction.Coating structure type
2/1: Coat the upper surface twice, coat the lower surface once, and bake twice.
2/1M: Coat the upper and lower surfaces twice and bake once.
2/2: Coat the upper and lower surfaces twice and bake twice.
Use of different coating structures:
2/1: The corrosion resistance and scratch resistance of the single-layer back paint are poor, but it has good adhesion,then can be applied to sandwich panels;
2/1M: The back paint has good corrosion resistance, scratch resistance and formability, and has good adhesion. It is suitable for single-layer profiled panels and sandwich panels;
2/2: The corrosion resistance, scratch resistance and processability of the double-layer back paint are better, and most of them are used for single laminated panels, as their poor adhesion, should not be used for sandwich panels.Jinan Zunkai Materials Co., Ltd founded in 2016 and we located in Shandong Province.
