Description
Pre-Painted Galvanized Steel Coils, PPGI, PPGL, Color Coated Coils
Color-coated rolls are light, beautiful and have good anti-corrosion properties, and can be directly processed. The colors are generally divided into gray, sea blue and brick red. Color-coated steel coils are mainly used in the advertising industry, construction industry, home appliance industry, electrical industry, furniture industry and transportation industry.
The paint used in the color-coated coil selects the appropriate resin according to the use environment, such as polyester silicon modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride, etc. Users can choose according to the purpose.
Prepainted galvanized steel coil is a kind of colour coated steel coil (PPGI coil). It uses galvanized steel as the base metal. The zinc layer offers strong corrosion resistance. Plus with painting, it is more durable than galvanized steel.The metallic coated steel then experiences some cleaning procedures, pre-treatment solutions and ultimately gets multiple layers of organic coatings, including laminates, vinyl dispersions, and paint. This continuous technique of applying different coatings is referred to as coil coating. Therefore, the steel coil doesnt require painting or finishing when employed in finished products.
To start with, they use different substrates. PPGI uses galvanized sheets as being the base metal. They have a zinc coating throughout to prevent moisture, rust, and corrosion from destroying the steels surface.The substrate for prepainted galvalume steel is a combination of 1.6% silicon, 43.3% zinc, and 55% aluminum. The substrate influences their applications which further differentiates the 2 kinds of steel.
The service life of these two types of steel also varies because of the substrates. The substrates prolong the steels service life by protecting them from rust and corrosion. Zinc is the perfect substrate for safeguarding steel from rust. PPGI has near to 99% zinc within its substrate, but PPGL only has 43.3%. This gives PPGI a longer service life in comparison with PPGL. Although aluminum and silicone are great alloys, they arent the best at protecting steel from corrosion or rust. They eventually wear out with time, thus exposing the steel to moisture that leads to corrosion.

Advantage
(1) It has good durability, and its corrosion resistance is longer than that of galvanized steel;
(2) It has good heat resistance and is less prone to discoloration at high temperatures than galvanized steel;
(3) It has good thermal reflectivity;
(4) It has processing performance and spraying performance similar to galvanized steel sheet;
(5) It has good welding performance.
(6) It has a good price-performance ratio, durable performance and very competitive price. Therefore, whether it is architects, engineers or manufacturers, galvanized steel sheets have been widely used in industrial buildings, steel structures and civil facilities, such as garage doors, gutters and roofs.
