Color Aluminum for Roller Shutter

Color-coated aluminum coils, with their advantages of being lightweight yet strong, corrosion-resistant, durable, available in a variety of colors, and easy to form, have become the preferred raw material for roller shutters in shops, garages, factories, logistics channels, and other scenarios.

Compared to traditional steel coils, they do not rust, are lighter, and operate more quietly; compared to ordinary aluminum alloys, the color coating further enhances their appearance and weather resistance.

Application Scenarios

Color aluminum coils are suitable for all scenarios including residential, commercial, and industrial use. Their core advantages cover three major needs: security, aesthetics, and durability:

Commercial Storefronts: Colored aluminum roller shutters are ideal for street-front shops and chain stores, offering a unified color scheme, clean look, and enhanced storefront image. They also offer fast and quiet opening and closing.

Residential Garages: The first choice for home garages. Their lightweight design reduces motor load, and they are corrosion-resistant and rust-proof, suitable for long-term use in coastal and humid areas.

Industrial Plants/Logistics Channels: Wind-resistant and impact-resistant, combined with electric/intelligent control, they meet the needs of high-frequency, large-size passage.

Special Environments: In humid/corrosive environments such as cold storage, basements, and coastal buildings, the corrosion resistance of colored aluminum is far superior to that of steel, requiring minimal maintenance.

Core Specifications

The standard thickness of the color-coated aluminum coils used in roller shutters ranges from 0.25mm to 1.2mm, with 0.5mm-0.8mm being the most common. 0.5mm-0.6mm thickness is suitable for residential applications (such as community garages and small shops), balancing lightweight design with basic protection; 0.7mm-1.2mm thickness is suitable for industrial applications.

The standard width of the coated aluminum coils is 1000mm-1500mm. Custom cutting can be made to fit the actual width of the roller shutter door to avoid excessive splicing that could affect aesthetics and sealing. Special sizes can be customized in advance with the manufacturer, with the maximum width extending to 1700mm.

Furthermore, the core diameter of the aluminum coil is typically 150mm, 405mm, or 508mm, and must match the roller shutter door's roller diameter to ensure smooth installation.

Coating Colors

The coating materials are mainly divided into two types: polyester coating (PE) and fluorocarbon coating (PVDF). Polyester coatings offer high cost-effectiveness, rich colors, and good weather resistance; PVDF coated aluminium provides superior corrosion resistance and UV resistance, withstanding high temperatures, sun exposure, and acid/alkali corrosion, making them suitable for industrial settings or harsh outdoor environments.

Regarding color selection, standard colors prioritize practicality and stain resistance, such as silver-gray, white, and light gray, which complement most architectural styles and are less prone to showing dirt, reducing cleaning frequency.

Shops can choose vibrant colors like red, blue, and coffee to enhance brand recognition, depending on their decor. Industrial settings can opt for calming tones like dark gray and black to highlight an industrial aesthetic.

Furthermore, colors can be customized based on RAL, Pantone international color charts, or customer samples. Custom textures such as wood grain and marble are also supported to meet personalized decorative needs. The coating gloss is adjustable (10%-90%) to suit different visual preferences.

Alloy Selection

The alloy choice of the color-coated aluminum coil directly determines the strength, plasticity, and corrosion resistance of the roller shutter door. Considering the application scenarios of roller shutter doors, commonly used alloys are mainly divided into 1-series, 3-series, and 5-series, each with its own advantages; choose according to your needs.

1-series alloys: 1050, 1060, 1100. They are soft, malleable, easy to cut and bend, suitable for small roller shutters (shop doors, storage room doors). They have good corrosion resistance and low cost but low strength, not for high-intensity impacts.

3-series alloys: 3003, 3004. They are stronger than 1-series, with good malleability and corrosion resistance, being the mainstream for roller shutters (most civilian and general industrial use). They meet bending requirements and resist daily impacts, with optimal cost-performance. 3004 is stronger than 3003, suitable for strength-required applications.

5-series alloys: 5052, 5754. They have the highest strength and excellent corrosion resistance, suitable for harsh outdoor environments or large industrial roller shutters (heavy-duty factories, open-air warehouses). They resist rain, snow, salt spray and have a long service life, but are relatively expensive with slightly lower plasticity than 1-series and 3-series, requiring selection based on processing needs.

Packaging and Transportation

The coating of color-coated aluminum coils is fragile and easily damaged. Proper packaging and transportation are critical, with protective measures required during shipment and on-site handling.

Multi-layer packaging protection: Wrap the surface with a neutral/weakly acidic protective film, add soft padding on the end face, place desiccants and seal in a plastic bag, then pack into a sturdy wooden box. Attach moisture-proof and anti-collision labels.

During transportation, we will choose long-term cooperative logistics and transportation fleets to ensure that the goods are intact. We will avoid loading and unloading aluminum coils during rainy or sunny weather.
