AZ150 Aluzinc Galvalumed Color Coated Steel Coil - Customize Color 20-45 Microns Organic Coating
Product Description:
Introduction
Colour coated coil is a versatile product that can be made from different substrates such as hot-dip galvanized sheet, hot-dip aluminium zinc plated sheet and electro-galvanized sheet. The manufacturing process usually involves pre-treatment, which includes chemical degreasing and chemical conversion treatment. After that, one or several layers of organic paint are coated on the substrate. The paint is then baked and cured to achieve a durable and aesthetically pleasing finish. The name of these coils is derived from the various colours of organic paint applied to them.
Using hot-dip galvanized steel strip as the substrate for colour coated steel strip provides a dual layer of protection. In addition to the zinc layer, the organic coating serves an extra shield to enhance rust prevention and extend the product's service life to about 1.5 times that of regular galvanized strips.
Features:
Color coated coils are a type of steel product that has an enhanced aesthetic appeal and improved corrosion resistance. Organic layers are added to the coils to achieve these benefits.
The application process for color coated coils involves the use of one or more layers of paint that are applied to the surface of the steel. This is commonly carried out via a continuous roller coating process to ensure uniformity in color and thickness. The end result is a visually attractive and highly durable product.
Key Features of Color Coated Coils
- Lightweight: Compared to other materials, color coated coils are significantly lighter in weight, making them easier to handle and install.
- Aesthetic Appeal: Available in a wide range of colors such as grey, white, sea blue, and brick red, the coils can effectively meet various design and aesthetic requirements.
- Corrosion Resistance: The coating on the steel coils provides excellent protection against corrosion, which significantly extends the lifespan of the steel.
- Direct Processability: The coils can be directly processed through bending, punching, and cutting to meet various requirements and applications, making them truly versatile.
- Cost-Effective: Despite their high performance and unique features, color coated coils are a cost-effective solution utilized in many industries.
Technical Parameters:
Coatings for Colour Coated Coils
The coatings for colour coated coils are selected based 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 compression moulding panels. It is good 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 board, but its adhesion is not good, and it is not suitable for sandwich board.
