Color coated corrugated aluminum roofing sheet is a type of rolled, cold-bent aluminum sheet formed into various corrugated shapes. It is widely used in building roofs, walls and other applications, offering excellent aesthetics and weather resistance.
Common alloy of color coated corrugated aluminum roofing sheet
– 1060 Pure Aluminum:
Containing over 99.5% aluminum, it is relatively soft, ductile, and offers excellent formability and corrosion resistance. It is relatively low in cost, but its strength and rigidity are relatively weak.
– 3003 Aluminum-Manganese Alloy:
Containing manganese alloying elements, it boasts better hardness and tensile properties than 1060 pure aluminum and excellent rust resistance, earning it the nickname “rust-proof aluminum.” It is widely used in aluminum roofing sheeting.
– 3004 Aluminum-Magnesium-Manganese Alloy:
Containing magnesium in addition to manganese, it offers higher strength than 3003 aluminum, excellent formability, and good corrosion resistance. It is one of the most widely used color coated aluminum products and is often used on the roofs of large public buildings such as airports and train stations.
Thickness
Typically between 0.5mm and 1.5mm, depending on design requirements.
Coating Types
– Polyester (PE) coating: Offers excellent weather resistance and decorative properties, guaranteed to last at least ten years without fading. Relatively affordable, it’s suitable for general roofing applications.
– Fluorocarbon (PVDF) coating: Made from a fluorocarbon resin based on fluoroolefins and acetylene, the coating’s compact molecular structure offers exceptional weather resistance, corrosion resistance, and UV resistance, making it suitable for public and industrial buildings requiring high durability.
Product Features
– Lightweight and High Strength:
Aluminum’s low density makes color coated corrugated aluminum roofing sheets lightweight, reducing support pressure. Furthermore, through a well-balanced alloy formulation and processing technology, the aluminum roofing sheets possess high strength and rigidity, meeting the load-bearing requirements of roofing.
– Various Colors:
The surface can be color-coated in a variety of color options, offering stable and fade-resistant colors. Customizable textures such as wood grain and stone grain can also be applied to meet the decorative needs of various buildings.
– Corrosion Resistance:
Aluminum has excellent rust resistance. A dense aluminum oxide film naturally forms on its surface, preventing further oxidation. Combined with the protection of a color coating, it offers strong corrosion resistance in harsh environments like rain and direct sunlight, ensuring a long service life.
– Easy Installation:
The corrugated design makes installation relatively easy, allowing for the use of specialized fasteners and tools. This speeds up installation and effectively shortens construction timelines.
– Environmentally Friendly and Recyclable:
Aluminum sheets are recyclable, resulting in high scrap value, meeting environmental standards and reducing the environmental impact of construction waste.
Applications of color coated corrugated aluminum roofing sheet:
– Building Roofing: Used for roof coverings of commercial buildings, industrial plants, and residential buildings, providing excellent waterproofing and thermal insulation.
– Wall Decoration: Used for exterior wall decoration to enhance the building’s appearance.
– Billboards and Signs: Due to its excellent surface finish and weather resistance, it is often used in billboards and signs.
