40 Years Warranty Coated RAL Color Pre-Painted Steel Coil For Z275 Galvanized AZ150 Galvalumed Baseplate
Product Description:
Colour coated coil is a product that has many applications due to its versatility. It is created using a variety of different substrates, including hot-dip galvanized sheet, hot-dip aluminum zinc plated sheet, and electro-galvanized sheet. The manufacturing process involves pre-treatment, which includes chemical degreasing and chemical conversion treatment, followed by the application of one or more layers of organic paint on top of the substrate.
The organic paint used on these coils gives them their name – colour coated coils. Once the paint has been applied, the coils are baked and cured to create a strong, durable finish that is both functional and aesthetically pleasing. The range of colors available for these coils makes them ideal for a variety of different applications, from roofing and cladding to interior decoration.
Using hot-dip galvanized steel strip as the substrate for colour coated steel strip provides an added layer of protection. In addition to the zinc layer, the organic coating adds an extra shield to the steel strip, enhancing rust prevention and extending the product's service life by approximately 1.5 times compared to regular galvanized strips.
Features:
Steel products coated with organic layers are known as color coated coils. These coils not only enhance the aesthetic appeal of steel, but also improve its corrosion resistance. The process of producing color coated coils involves applying one or more layers of paint to steel using a continuous roller coating method. This ensures uniformity in color and thickness, making them highly durable and visually attractive.
Key Features
- Lightweight: Compared to other materials, color coated coils are significantly lighter, making them easy to handle and install.
- Aesthetic Appeal: Available in a wide range of colors such as grey, white, sea blue and brick red, color coated coils can meet various design and aesthetic requirements.
- Corrosion Resistance: The coating provides excellent protection against corrosion, which helps extend the lifespan of the steel.
- Direct Processability: Color coated coils can be directly processed through bending, punching and cutting, which makes them versatile for various applications.
- Cost-Effective: Despite their high performance, color coated coils are a cost-effective solution for many industries.
Technical Parameters:
Coatings for Colour Coated Coils
The selection of coatings for colour coated coils is dependent on the specific environmental conditions in which they will be used. Different resins are employed to ensure optimal performance:
- Polyester: Offers good adhesion, rich colours, formability, and outdoor durability at a low cost.
- Silicone Modified Polyester (SMP): Provides good film hardness, abrasion resistance, heat resistance, exterior durability, and resistance to chalking. It also retains gloss well and has general flexibility at a medium cost.
- High Durability Polyester (HDP): Known for excellent colour retention, UV resistance, exterior durability, and chalking resistance. It also has good film adhesion, rich colours, and provides excellent cost performance.
- Polyvinylidene Fluoride (PVDF): Known for exceptional colour retention, UV resistance, outdoor durability, chalking resistance, solvent resistance, and dirt resistance. It offers good formability but is available in limited colours and comes at a higher cost.
These characteristics and diverse applications make colour coated coils a popular choice across multiple industries, combining functionality with aesthetic appeal.
Coating Structures
Type of coating structure:
- 2/1: Coat upper surface twice, lower surface once, bake twice.
- 2/1M: Coat upper and lower surfaces twice, bake once.
- 2/2: Top and bottom surfaces are coated twice each and baked twice.
Usage of different coating structures:
- 2/1: The corrosion resistance and scratch resistance of single layer back coating is poor, but it has good adhesion, mainly used for sandwich panels. It is mainly used for sandwich panels.
- 2/1M: Backcoat with good corrosion resistance, scratch resistance and moulding properties, good adhesion, suitable for single-layer pressboards and sandwich panels. Good corrosion resistance, scratch resistance and moulding properties, good adhesion, suitable for single-layer pressboards and sandwich panels.
- 2/2: Double-layer backing paint with good corrosion resistance, scratch resistance and processability, mostly used for single-layer pressboards, but with good adhesion. Most of them are used for single-layer moulding boards, but its adhesion is not good, and it is not suitable for sandwich boards.
