Color Coated Aluminum Coil For Louvers

Color coated aluminum coil for louvers are decorative materials formed by coating aluminum coils with polyester (PE) or fluorocarbon (PVDF) coatings using a roller coating process and then baking at high temperatures. They are lightweight, corrosion-resistant, and available in a variety of colors, making them a core raw material for aluminum alloy louvers.

The specifications of color coated aluminum coil for louvers:

- Alloy grades:

Commonly used alloy grades include 1000 series aluminum such as 1050, 1060, and 1100; 3000 series aluminum alloys such as 3003 and 3004; and 5000 series aluminum alloys such as 5005 and 5052. 1060 color coated aluminum coils are widely used due to their good corrosion resistance and moderate cost.

- Thickness:

Common thicknesses range from 0.2mm to 4.0mm, but for louvers, the thickness is generally between 0.3mm and 1.2mm, with around 0.6mm being the most common.

- Width:

Widths typically range from 180mm to 1600mm, depending on the required blind size. Common widths include 600mm, 1000mm, and 1200mm.

- Coating types:

Mainly PE polyester coating and PVDF fluorocarbon coating. PE polyester single-coat thickness is generally 15-18 micrometers, PE polyester double-coat thickness is approximately 25 micrometers, and PVDF fluorocarbon coating thickness is also typically 25 micrometers.

- Colors:

A wide variety of colors are available; refer to the RAL color chart for selection. Common colors include white, gray, blue, green, and red. Custom colors can also be customized upon request.

- Roll inner diameter:

Generally 508mm-610mm, this is to accommodate common coil storage and processing equipment.

Production process of color coated aluminum coil for louvers:

- Substrate pretreatment:

Aluminum coils undergo degreasing, chemical cleaning, and passivation to form a conversion film, improving coating adhesion and corrosion resistance.

- Roller coating process

Primer and topcoat: Aluminum coils are coated with primer and topcoat sequentially via a roller coater, forming a continuous solid film after drying.

Curing control: The curing oven temperature is set at 200-300℃ to ensure complete curing of the coating and removal of volatiles, preventing coating cracking or peeling.

- Precision control

Thickness Tolerance: High-end products maintain a thickness tolerance within ±0.05mm to ensure processing accuracy.

Edge Treatment: A leveling machine eliminates edge deflection, preventing excessive gaps during installation that could lead to leaks.

Advantages of color coated aluminum coil for louvers:

- Weather resistance:

Color coated aluminum coils undergo special treatment to resist UV rays, rain, and other environmental factors, maintaining vibrant colors and resisting fading.

- Lightweight and high strength:

Aluminum is lightweight, facilitating transportation and installation, while possessing good strength to withstand wind pressure and impact.

- Diverse colors and textures:

Coated aluminum coils can be customized with various colors and surface textures to meet different architectural styles.

- Environmentally friendly:

Aluminum is recyclable, and the coating material meets environmental standards, causing no pollution.

- Easy to process:

Aluminum coils can be easily cut, bent, and shaped to adapt to different design requirements.

- Economical:

Compared to other materials, color coated aluminum coils are cost-competitive and suitable for mass production.

Applications of color coated aluminum louvers:

- Residential buildings

Interior and exterior decoration: Polyester-coated aluminum coils are used for balcony and bedroom blinds, offering vibrant colors at a lower cost.

Privacy and light balance: Ventilation and shading functions are achieved by adjusting the blade angle.

- Commercial buildings

Large shopping malls and office buildings: Fluorocarbon-coated aluminum coils are used for curtain wall louver systems, offering strong weather resistance and low maintenance costs.

Public facilities: For locations such as airports and convention centers, 1mm thick aluminum-magnesium-manganese color-coated coils are used to meet the requirements of large-span roof structures, while curved designs create a distinctive appearance.

- Special environments:

Coastal areas: In high-salt-spray environments, fluorocarbon-coated aluminum coils resist corrosion and extend service life.

Industrial areas: Chemically resistant coatings protect louvers from acid and alkali corrosion.

Color coated aluminum coils for louvers have become the preferred material for modern architecture due to their lightweight, corrosion resistance, and strong decorative properties. When purchasing, it is necessary to comprehensively select the alloy grade, coating type, and thickness specifications based on the usage environment (e.g., outdoor/indoor, coastal/inland), design requirements (e.g., color, texture), and budget to ensure the best balance between performance and cost.
