Color coated channel letter coil is a material commonly used in the production of advertising signs and logos. It is typically made of aluminum with a color coated surface, offering excellent weather resistance and aesthetics.
The base material of color coated aluminum channel letter coil is 1000 series pure aluminum (such as 1060, 1100), 3000 series aluminum-manganese alloy (3003), 5000 series aluminum-magnesium alloy (5052), or 6000 series aluminum-magnesium-silicon alloy (6061). Thickness typically ranges from 0.12 to 1.5 mm. 3003 aluminum alloy is the mainstream choice due to its corrosion resistance and ease of processing, while 6061 aluminum alloy is suitable for applications requiring higher strength.
Surface Treatment of Color Coated Channel Letter Coil:
- Fluorocarbon coating (PVDF): The coating offers strong adhesion and excellent weather resistance, guaranteeing over 10 years of non-fading and non-chipping resistance, making it suitable for long-term outdoor use.
- Polyester paint (PE): Low cost, vibrant colors, suitable for indoor or short-term outdoor use.
- Brushed Finish: Mechanically polished to create metallic textures, such as brushed gold and brushed silver, for a premium feel and exceptional scratch resistance.
- Mirror Finish: Imitation stainless steel, with high brightness and uniform reflection, commonly used for high-end brand logos.
Physical Properties of Color Coated Aluminum Channel Letter Coil:
- Lightweight and High-Strength: With a density only one-third that of steel, it's easy to install and resists deformation.
- Flexibility: The 0.6mm thick aluminum channel letter coil strips can be easily bent and formed, adapting to complex font outlines.
- Fireproof and Moisture-Resistant: The aluminum alloy base is non-flammable, and the surface coating provides a degree of moisture resistance, making it suitable for a variety of environments.
Specifications of Color Coated Channel Letter Aluminum Coil:
- Height: Commonly 5-8cm, with 5cm suitable for fonts under 80cm, and 8cm for larger sizes to ensure even polishing.
- Width: Available in rolls from 1.5-7cm to accommodate varying font thickness requirements.
- Length: Typically shipped in 50- or 100-meter rolls, saving material and facilitating mass production on CNC engraving machines.
Color System of Color Coated Channel Letter Coil:
- Basic Colors: A full range of standard colors, including bright white, matte white, high-gloss black, matte black, red, yellow, blue, and green.
- Metallic Colors: Brushed gold, brushed silver, titanium gold, and natural aluminum, highlighting a high-end finish.
- Specialty Colors: Customized colors such as stainless steel mirror silver, postal green, and telecommunications blue, meeting brand identity needs.
Core Applications of Color Coated Aluminum Channel Letter Coil:
- Commercial Signage: Storefronts, shopping mall signage, and chain store signs enhance brand recognition with a metallic finish.
- Illuminated Letter Production: Lining materials for resin, borderless, and super-letter letters, combined with LED light strips for uniform illumination.
- Architectural Decoration: Curtain wall corners, door and window edging, cornice moldings, and other applications, ensuring both waterproofness and aesthetics.
- Event Displays: Exhibition panels, promotional poster frames, and other applications, lightweight, easy to install, and reusable.
Significant Advantages of Color Coated Channel Letter Coil:
- Efficient Processing: CNC lettering machines enable rapid prototyping, allowing a single operator to complete a 1-meter lettering border in 15 minutes, significantly reducing labor costs.
- Low Maintenance: The fluorocarbon coating is UV- and corrosion-resistant, requiring only daily cleaning with water to maintain its shine.
- Flexible Design: Customizable colors, sizes, and bend radiuses are supported, accommodating unique fonts and creative designs.
Color coated aluminum channel letter coil have become a mainstream material in the advertising sign industry due to their cost-effectiveness, durability, and design flexibility. With technological advancements and increasing environmental awareness, their application in smart signage, green buildings, and other fields is expected to expand.
