Description
Pre-coated galvanized steel and pre-coated galvanized aluminum (PPGI & PPGL), often referred to as pre-coated steel or color-coated steel coils, are a wide range of materials used in construction, manufacturing and other industrial applications. The basic materials of these products include hot-dip galvanized steel plate, hot-dip galvanized aluminum plate, electric galvanized steel plate, etc., which are all by plating a layer of zinc or aluminum on the surface of the steel to improve the corrosion resistance of the material.
In the production process, the steel plate is first subjected to strict surface pretreatment, this step is to remove the surface of oil, dust, rust and other impurities, to ensure that the coating and the surface of the steel plate good adhesion. After the pretreatment is completed, the surface of the steel plate is coated with one or more layers of organic coatings, which not only provide additional anti-corrosion protection, but also give the material a rich color and gloss, thus improving the aesthetic appearance of the material. Once coated, the steel plate is fed into a baking oven for curing, a step that hardens the coating to create a strong, durable surface.
Because of its lightweight characteristics, the color coated steel coil makes the transportation and installation more convenient and fast. Its diverse appearance and bright colors can not only meet the needs of different architectural decoration, but also enhance the overall beauty of the building. In addition, due to its excellent anti-corrosion properties, color-coated steel coils can maintain a long service life under different environmental conditions, reducing the frequency of maintenance and replacement.
Another advantage of color coated steel coil is that it can be processed directly, such as cutting, bending, punching, etc., which makes it highly flexible in design and application. Whether used for roofs, walls, partitions or other decorative purposes, color-coated steel coils meet the demanding material performance and appearance design requirements of modern buildings.
As a new type of building material, pre-coated galvanized steel and pre-coated galvanized aluminum have been widely used and recognized in the construction and manufacturing industries for their lightweight, beautiful, durable and easy to process characteristics.

Coating Type
Polyester (PE): Good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical resistance, and low cost.
Silicon modified polyester(SMP): Good abrasion resistance and heat resistance, as well as good external durability and chalking resistance, gloss retention, general flexibility, and medium cost.
High Durability Polyester(HDP): Excellent color retention and anti-ultraviolet performance, excellent outdoor durability and anti-pulverization, good paint film adhesion, rich color, excellent cost performance.
Polyvinylidene Fluoride(PVDF): Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good moldability, stain resistance, limited color, and high cost.
Substrate type
Substrate type refers to the type of material used as a support or foundation in the manufacturing process. The following are several common substrate types and their characteristics:
Hot dip galvanized color coated steel plate (pre-coated galvanized steel plate) :
This substrate is a product made by coating a layer of organic coating on the surface of hot-dip galvanized steel plate, which is called hot-dip galvanized color coated plate. The hot-dip galvanized color coated plate not only inherits the protective characteristics of the zinc layer of the hot-dip galvanized steel plate, but also increases the anti-rust effect of the organic coating, which makes its service life significantly improved compared with the ordinary hot-dip galvanized plate. This material is commonly used in the construction industry because of its long weather resistance and corrosion resistance, which can maintain good performance in different environments.
Hot dip aluminum zinc color coated plate (pre-coated galvanized steel plate) :
Hot dip aluminum zinc steel plate is a specially treated steel plate, its surface contains 55% aluminum and 43.5% zinc, or 5% aluminum and 95% zinc, this material can also be used as a substrate for color coated plates. Hot-dip aluminum zinc color coated plate has good corrosion resistance and wear resistance, suitable for a variety of harsh environmental conditions, so it is often used in building external walls, roofs and other occasions that need long-term weather resistance.
Electrogalvanized color coated plate:
Electrogalvanized color coated plate is made of electrogalvanized plate as the base material by coating organic coating on its surface and baking treatment. Electrogalvanized color coated board not only has a beautiful appearance, but also has good processing properties, making it an ideal choice for home appliances, audio, steel furniture, interior decoration and other fields. Due to the organic coating on its surface, the electrogalvanized color coated board also has a certain corrosion resistance and pollution resistance, which is suitable for indoor environments that need to be kept clean and beautiful.
Different types of substrates offer a wide range of options for a variety of applications based on their unique chemical composition and surface treatment. Whether in outdoor construction or interior decoration, choosing the right substrate type is crucial to ensuring the performance and longevity of the final product.
