Colored coated embossed aluminum roofing coil is a widely used decorative material for building roofs and walls, featuring strong weather resistance, rich colors, and easy installation.
- Coating: The surface of the aluminum coil is treated with a coating that offers various colors and patterns, enhancing not only aesthetics but also weather resistance and corrosion resistance. The coated materials can utilize high-performance coatings such as Polyester (PE) and Fluorocarbon (PVDF) to ensure long-term color stability and durability.
- Embossing: The surface of the colored coated aluminum coil undergoes an embossing process to form various patterns or textures. This treatment not only increases the aesthetic appeal of the material but also improves slip resistance, reduces noise from rainwater runoff, and enhances its rigidity and strength.
Colored coated embossed aluminum roofing coil combines decoration, weather resistance, and structural stability, and is widely used in commercial buildings, industrial plants, and high-end residential projects.
- Material Selection: Common materials include 1060 pure aluminum coil, 3003 aluminum-magnesium-manganese alloy, and 3004 alloy, with thickness ranging from 0.2-6.0mm and width up to 2600mm
- Coating Process: Uses fluorocarbon paint, polyester paint, or epoxy resin coating, supporting matte, semi-gloss, and high-gloss surface treatments, with customizable colors.
"Colored Coated Embossed Aluminum Roofing Coil" represents a high-performance modern roofing material integrating light weight, high strength, durability, aesthetics, and environmental friendliness, and is one of the preferred choices for large public building roofs.
Why Choose Colored Coated Embossed Aluminum Roofing Coil?
Aluminum:
Base Material: Refers to the metal aluminum as the core material. Common aluminum alloy grades include 1050 (pure aluminum, strong corrosion resistance), 3003 (manganese alloy, higher strength), 3004 (magnesium alloy, suitable for deep drawing), with thickness typically ranging from 0.2-1.2mm and width customizable up to 1600mm.
Features: Lightweight (density about 1/3 of steel), corrosion-resistant, good plasticity, easy to process, 100% recyclable, environmentally friendly.
Embossing:
Surface Treatment: During the rolling of aluminum coil, mechanical rollers create textures such as orange peel, diamond, wood, or stone patterns, enhancing three-dimensional effect and anti-slip performance, while improving coating adhesion and scratch resistance.
Common Patterns: Orange peel, diamond, pearl, etc.
Functions:
- Aesthetic: Enhances three-dimensionality and texture, hides minor scratches that may occur during transportation and installation.
- Stiffness Enhancement: The patterned structure effectively increases the mechanical strength of the panel, making it less prone to deformation.
- Anti-Glare: Diffuse reflection reduces direct sunlight glare.
Colored Coating:
Surface Treatment: After chemical treatment of the aluminum coil surface, multiple layers of paint are applied, usually using the "baking finish" process (roller coating followed by high-temperature curing).
Coating Structure (usually two layers with three coatings or more):
Primer: Enhances adhesion between coating and aluminum sheet, providing additional corrosion protection.
Topcoat: Provides rich color options and weather resistance. Common topcoat types include:
- Polyester: Cost-effective, good weather resistance, rich colors, most commonly used.
- Fluorocarbon: Premium option, excellent weather resistance, UV resistance, and self-cleaning properties, extremely long service life, commonly used in high-end buildings and harsh environments.
- High-Performance Polyester: Performance between polyester and fluorocarbon.
Functions: Provides long-lasting decorative effects and extra protection, preventing aluminum from corrosion and discoloration.
- PVDF (Fluorocarbon Coating): Thickness ≥25μm, strongest weather resistance, provides 20-30 years warranty, suitable for high-corrosion environments (e.g., coastal areas), higher cost.
- Polyester (PE): Thickness ≥18μm, cost-effective, suitable for general buildings, warranty about 10-15 years.
- Special Coatings: Such as self-cleaning nano coatings (reduces maintenance cost by 50%), diffuse reflection coatings (reflectivity ＞95%, significant energy-saving effect).
Colored Coated Embossed Aluminum Roofing Coil
Performance Features
- Lightweight and High Strength: Significantly reduces roof structural load while providing sufficient strength to withstand wind pressure, snow load, and construction load.
- Excellent Weather Resistance: Aluminum substrate is naturally corrosion-resistant, and the colored coating (especially fluorocarbon coating) provides protection against long-term UV, rain, acid rain, salt spray, keeping colors vibrant and service life up to several decades.
- Attractive and Diverse: Wide range of colors and embossed textures to meet various architectural aesthetic requirements.
- Outstanding Waterproofing: When formed into standing seam systems, mechanical interlocking creates a perforation-free roof system with excellent sealing.
- Easy and Economical Installation: Coil form reduces transportation cost, on-site forming is efficient, and systemized installation is fast.
- Environmentally Friendly and Energy-Saving: Aluminum is 100% recyclable, and high-reflectivity light-colored surfaces help reduce urban heat island effect and lower air conditioning energy consumption.
- Long Lifespan: PVDF-coated roofs can last more than 30 years, far exceeding traditional asphalt shingles (15-20 years).
- Energy Saving: Diffuse reflection coatings reduce indoor temperature by 3-5℃, combined with insulation layers, meeting LEED certification requirements.
