Color Coated Steel Coil

Pre-painted Steel Coil

Product Introduction and Common Specifications

Color coated coil is a steel product that is processed by surface pretreatment, coating and curing with steel coil as the base material. Its coating often uses high-performance coatings such as polyester (PE), fluorocarbon (PVDF), acrylic (ACP), etc. These coatings not only provide a variety of color options, but also have excellent weather resistance and corrosion resistance. Color coated coils are widely used in many industries such as construction, home appliances, and automobiles, and have become one of the indispensable high-performance materials in modern manufacturing.

In terms of specifications, color coated coils are usually available in a variety of sizes and thicknesses. Its common width is between 600mm and 1250mm, and the thickness ranges from 0.15mm to 1.2mm. According to specific application requirements, users can customize color coated coils of different thicknesses and widths, with the most common width being 1000mm or 1219mm. The coating types of color coated coils can be divided into polyester (PE), fluorocarbon (PVDF), and acrylic (ACP). The thickness of the coating is generally controlled between 10μm and 30μm to ensure the uniformity and durability of the coating.

Product Application and Advantages

Color-coated coils are widely used in construction, home appliances, automobiles, and household applications. In construction, they are applied to facades, roofs, walls, and enclosures, especially in modern high-rise buildings where their durability and aesthetic appeal make them a popular choice for exterior decoration. In the home appliance sector, they are commonly used for the shells of refrigerators, washing machines, and air conditioners, valued for their smooth finish, rich colors, and corrosion resistance. 

The advantages of color-coated coils are reflected in four key aspects.

Aesthetics: With smooth surfaces and a wide range of colors, they offer flexible design options to meet diverse decorative needs in buildings, appliances, and household products.

Corrosion resistance: Advanced coatings protect the steel substrate from humidity, acids, and alkalis, ensuring long service life even in harsh environments.

Lightweight and strong: Easy to process and transport while maintaining excellent structural strength, making them suitable for complex applications.

Eco-friendly: The coating materials comply with green building standards, supporting sustainable development and environmentally friendly construction.

Product quality inspection methods

In the production of color-coated coils, strict quality control is essential. The process begins with rigorous inspection of raw materials to ensure that the flatness, thickness, and surface quality of the steel substrate meet required standards. During the coating stage, the thickness, uniformity, and adhesion of the coating are carefully monitored to prevent defects such as peeling, bubbling, or scratching. A series of physical and chemical tests—including adhesion, hardness, and weather resistance tests—are conducted to guarantee reliable performance under various conditions. For example, ultraviolet accelerated aging tests and damp heat tests are commonly applied to evaluate durability and anti-aging properties. Furthermore, precise instruments are used to measure the width, length, and thickness of the coils, ensuring they fully comply with customer specifications.
