Product introduction of color-coated rolls

Color-coated coils use hot-dip galvanized sheets, hot-dip galvalume sheets, electro-galvanized sheets, etc. as substrates. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are coated on the surface, and then A product that is baked and solidified. Colored steel coils are named after being coated with organic coatings of various colors, referred to as color-coated coils.

Characteristics of color-coated coil substrate

Electro-galvanized substrate: The coating is thinner and its corrosion resistance is not as good as that of hot-dip galvanized substrate;

Hot-dip galvanized substrate: A thin steel plate is immersed in a molten zinc bath to adhere a layer of zinc to the surface. This galvanized plate has good paint adhesion and weldability.

Features:

(1) It has good durability and corrosion resistance and has a longer lifespan than galvanized steel plates;

(2) It has good heat resistance and is less likely to discolor at high temperatures than galvanized steel plates;

(3) Has good heat reflectivity;

(4) It has processing performance and spraying performance similar to those of galvanized steel sheets;

(5) Has good welding performance.

(6) It has good performance-price ratio, durable performance and extremely competitive price. Therefore, whether it is architectural designers, 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.

三: Use of color-coated rolls

Color-coated rolls are lightweight, beautiful and have good anti-corrosion properties, and can be processed directly. The colors are generally divided into gray and white, sea blue and brick red. They are mainly used in the advertising industry, construction industry, home appliance industry, electrical appliance industry, furniture industry and transportation. Industry.

The coating used for color-coated rolls selects appropriate resins according to different use environments, such as polyester silicon-modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride, etc. Users can choose according to their usage.
