Product introduction
Color Steel Coil
Color steel coil is the type of steel plate with organic coating. It is generally used outdoors as a roof or wall, and is suitable for industrial and civil buildings, warehouses, and special facilities
The roof and interior and exterior wall decoration of various buildings have the characteristics of light weight, high strength, rich color, convenient and fast construction, earthquake resistance, fire prevention, and rain resistance.
Color Aluminum Coil
Color aluminum refers to the coloring treatment of the surface of aluminum alloy, which is a new type of building material complementary to color steel. The unique chemical properties of aluminum will quickly generate an oxide film on the surface, covering the aluminum surface to prevent rust, corrosion, and acid and alkali resistance

Why aluminum coils are more cost-effective?
Cost advantage
Colored aluminum is lightweight, with the density one-third of that of color steel. Under the same weight, the square of color aluminum is about three times that of color steel. When calculated for the price per square meter, the price of color aluminum is almost the same as that of color steel.
Low maintenance
Colored aluminum has excellent corrosion and weather resistance, as well as self-cleaning ability, which is not easy to rust and requires almost no maintenance costs. The essence of color steel is that iron is prone to rust, difficult to maintain, and has high costs
Long service life
The service life of colored aluminum is 30years and the service life of colored steel is 10 years.The service life of colored aluminum is three times that of colored steel, and it only requires one cost expenditure to maintain durability for 30 years
High recycling value
Aluminum is 100% recyclable, and the recycling value is more than 80% of the original cost.The recycling value of corroded steel is extremely low and has almost no secondary use value.

Our Production Process
Coil Preparation
High quality aluminum coil raw materials are the foundation of production, and each coil of aluminum must undergo strict weighing and quality testing before being put into production to ensure that it meets production standards
Unwinding
The weighed aluminum coils are put into the uncoiler for uncoiling to prepare for subsequent processing. After uncoiling is completed, the aluminum coil enters the pretreatment stage.
Pre-treatment
Pretreatment includes degreasing, washing, light extraction, re-washing, drying, passivation and re-drying.This step is the key to ensuring the quality of color-coated aluminum coil products.
Painting
After the pretreatment is completed, the aluminum coil enters the coating stage. This stage is the core link in forming the decorative effect of roller-coated aluminum. The coating process uses an advanced four-roller coating process, including film fixing roller, a pick-up roll, a transfer roll and a coating roll.
Drying and cooling
After the coating is completed, the aluminum coil needs to go through a drying and cooling process. This step is to allow the coating to cure and adhere to the aluminum plate better, ensuring the durability and stability of the product.
Quality inspection and Recoil
We have carried out strict quality control on every production link to ensure that the products meet high standard quality requirements. Aluminum coils that pass the inspection will be coated and rolled to protect the coating from damage and facilitate subsequent transportation and use.
