When choosing a roofing material, many prioritize durability and a premium appearance, and the aluminum roofing coil perfectly meets both of these requirements. Due to its unique material advantages, it is becoming a popular choice for residential and commercial roofing.
Aluminum alloys offers excellent corrosion resistance and withstands the effects of rain, UV rays, high and low temperatures, and other harsh weather. Even with prolonged outdoor exposure, they are resistant to rust, cracking, and aging, offering a service life of 20-30 years. This significantly reduces the frequency and cost of roof maintenance, making them particularly suitable for areas with high temperatures, rain, or significant temperature fluctuations.
Compared to traditional tile and slate roofing materials, the color coated aluminum coil lighter, weighing only 2-5 kg per square meter, significantly less than the 20-30 kg per square meter of ceramic tiles. This lightweight feature reduces the load-bearing requirements of the roof, making it suitable not only for new construction but also for renovations of older roofs, avoiding structural damage caused by excessive weight.
Aluminium roofing coil can be laid seamlessly through overlapping or welding processes, effectively avoiding the leaks common at the joints of traditional tiles. Furthermore, the aluminum coil's special surface treatment quickly channels rainwater, reducing erosion caused by accumulated water. It's particularly suitable for flat or gently sloping roofs.
They can be flexibly cut and laid to fit the curvature and angles of the roof. They can easily adapt to rectangular roofs, curved roofs, and complex roofs with skylights and exhaust ducts. Furthermore, the installation process is relatively simple, requiring no complex tools, shortening the construction period and reducing labor costs.
Fluorocarbon coating is one of the most weather-resistant coatings currently available, effectively resisting UV radiation, acid rain, and high-temperature aging. This type of coating is commonly used in commercial buildings (such as shopping malls and office buildings) or in coastal areas where weather resistance is critical, and can withstand humid, salt-fog-rich environments.
Polyester coating offers a more cost-effective solution, with excellent impact resistance and flexibility, adapting to even minor roof deformations without peeling. While slightly less weather-resistant than fluorocarbon coating, it can still provide 15-20 years of service in inland areas with relatively mild climates. Its wide selection of colors makes it suitable for cost-conscious residential users.
Width: The most common widths are 1.2m and 1.5m, though custom options are available. Wider widths reduce joints during installation, resulting in improved waterproofing and suitable for large roofs. Smaller widths are more suitable for complex roofs with numerous corners, allowing for more flexible cutting.
Length: Typically it is available in rolls of 10m or 20m, custom lengths can be tailored to suit the roof area, minimizing material waste.
Thickness: The base material is generally 0.3-0.8mm thick, while the coating is approximately 20-50μm thick. Welcome to inquire metal roofing coil prices from us directly.
