Color coated roll use

Color-coated rolls are lightweight, beautiful and have good anti-corrosion properties, and can be processed directly. 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 silicone modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride, etc. Users can choose according to their usage.

Coating structure type

2/1: Coat the upper surface twice, 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.

Uses of different coating structures:

2/1: The single-layer back paint has poor corrosion resistance and scratch resistance, but has good adhesion and is mainly used in sandwich panels;

2/1M: The back paint has good corrosion resistance, scratch resistance and processability, and has good adhesion. It is suitable for single-layer profiled panels and sandwich panels.

2/2: The double-layer back paint has good corrosion resistance, scratch resistance and processability. It is mostly used for single-layer profiled boards, but its adhesion is poor and it is not suitable for sandwich boards.

Color coated coil substrate classification

Hot-dip galvanized base plate

The product obtained by coating organic coatings on hot-dip galvanized steel panels is hot-dip galvanized color-coated panels. In addition to the protective effect of zinc, the hot-dip galvanized color-coated sheet also has an organic coating on the surface that protects and prevents rust, and has a longer service life than hot-dip galvanized sheets. The zinc content of hot-dip galvanized substrates is generally 180g/m2 (double-sided), and the zinc content of hot-dip galvanized substrates for exterior buildings is up to 275g/m2. The hot-dip galvanized substrates are made of hot-dip aluminum-zinc steel sheets (55% Al- Zn) as a newly coated substrate, usually contains aluminum and zinc content of 150g/m' (double-sided). The corrosion resistance of hot-dip galvanized sheets is 2-5 times that of hot-dip galvanized sheets. Continuous or intermittent use at temperatures up to 490°C will not cause serious oxidation or scale. The ability to reflect heat and light is twice that of hot-dip galvanized steel, and the reflectivity is greater than 0.75, making it an ideal building material for energy saving.

Characteristics of color-coated coil 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. Hot-dip aluminum-zinc substrate: This product is plated with 55% AL-Zn and has excellent anti-corrosion properties. Its service life is more than four times that of ordinary galvanized steel plates. It is a replacement product of galvanized sheet.

Features:

(1) It has good durability and corrosion resistance and has a longer service life 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.

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.
