Pre-Painted Galvanized Steel Coil / Color Coated Steel Coil

Color coated coil is a composite material made of **high quality galvanized coil (GI) or galvanized aluminum coil (GL/GL AZ)** as the substrate. After strict surface pretreatment (cleaning and passivation), it is evenly coated with one or more layers of high performance **organic coating** (such as polyester, silicon modified polyester, high durability polyester, polyvinylidene fluoride, etc.) on both sides through **roller coating** process on a continuous production line, and then cured by baking. It perfectly combines the strength and formability of the metal substrate with the decorative and protective properties of the organic coating. It is the preferred material for modern architecture, home appliances and industrial fields that pursue beauty, durability and environmental protection.

Description

 

1. **Excellent decorativeness and diversity:**
* **Rich colors:** Thousands of standard colors (such as RAL, Pantone) and customized color options are available to meet personalized design needs.
* **Various surface effects:** High gloss, matte, pearlescent, metallic texture, suede, stone grain, wood grain embossing, etc., provide rich visual and tactile experience.
* **Durable beauty:** High-quality coatings have good gloss and color retention, and are not easy to fade or lose gloss after long-term use.

2. **Superior weather resistance and protection:**
* **Double protection:** The surface organic coating isolates corrosive media (rainwater, ultraviolet rays, pollutants), and the bottom galvanized layer provides sacrificial anode protection, and the synergistic effect achieves a long life far exceeding that of a single material (usually more than 15-30 years, depending on the coating system).
* **Excellent weather resistance:** Specially formulated coatings (such as PVDF fluorocarbon) have excellent resistance to ultraviolet rays, acid rain, salt spray, and humidity and heat, and are suitable for harsh climate environments (coastal, industrial areas, and high ultraviolet areas).
* **Chemical corrosion resistance:** Resistant to corrosion by a variety of chemicals, keeping the surface intact.

3. **Excellent processing formability:**
* The coating has good flexibility and strong adhesion to the substrate. It can withstand a variety of processing methods such as bending, stamping, deep drawing, roll forming, etc., and is not easy to crack or peel off.
* Suitable for complex modeling processing of building roofs and wall panels.

4. **Excellent self-cleaning and low maintenance:**
* The smooth and dense coating surface is not easy to accumulate dust and stains, and can be kept clean by rain washing (especially PVDF coating).
* Greatly reduce the cost of later cleaning and maintenance.

5. **Good functionality:**
* **Heat insulation/insulation:** It can be made into sandwich panels with composite insulation materials (such as PUR/PIR), which significantly improves the energy saving effect of buildings.
* **Sound insulation:** It is also suitable for building parts that require sound insulation.
* **Special functional coatings:** Functional coatings such as antibacterial, antistatic, self-cleaning (photocatalyst), and high temperature resistance can be provided.

6. **Environmental protection and sustainability:**
* Strict VOC emission control during the production process complies with environmental regulations.
* The steel substrate is 100% recyclable and the coating can be processed and separated.
* Long life reduces resource consumption and construction waste.
* Reflective light-colored coating helps reduce building energy consumption (cool roof effect).

7. **High cost performance:**
* One-time investment, long-term benefits. It combines material cost, installation convenience, low maintenance cost and long service life, with significant economic advantages.
