Khi lựa chọn tiêu chuẩn hợp kim nhôm phù hợp để sử dụng làm ngói lợp, một số yếu tố cần được xem xét, bao gồm cả sức mạnh, khả năng chống ăn mòn và khả năng làm việc của hợp kim nhôm, cũng như phạm vi phủ sóng cần thiết và dễ dàng lắp đặt. Nói chung, gạch hợp kim nhôm cần có khả năng chống gió nhất định, chống mưa, và chống ăn mòn, and need to be easy to install and maintain.
Ví dụ, 3000 loạt, 5000 loạt và 6000 series have excellent corrosion resistance and mechanical strength. These properties are particularly critical for roofing tiles.
Common aluminum alloy tiles have various specifications, with lengths of 600mm, 800mm, 1000mm, vân vân., widths usually between 400mm ~ 420mm, and thicknesses generally 0.35mm ~ 0.60mm
Information on common specifications of aluminum alloys suitable for roofing tiles:
1. Aluminum alloy material
Aluminum alloy roof tiles are usually made of 3003 hợp kim nhôm or aluminum-magnesium-manganese alloy (such as AA3050). 3003 aluminum alloy has good processing properties and corrosion resistance, while aluminum-magnesium-manganese alloy is widely used for its excellent strength and corrosion resistance.
2. độ dày
The thickness of aluminum alloy roof tiles generally ranges from 0.4mm to 1.2mm. Thinner aluminum alloy sheets can reduce roof loads, while thicker sheets provide better strength and durability. The choice of specific thickness depends on the design requirements of the building and the load that the roof needs to bear.
3. xử lý bề mặt
The surface treatment of aluminum alloy roof tiles has a great impact on its appearance and durability. Common surface treatments include anodizing, coatings (such as fluorocarbon paint), roller coating, vân vân. These treatments can improve the weathering and corrosion resistance of aluminum alloys, while providing a variety of color options to suit different building designs.
4. Strength and ductility
Aluminum alloy roof tiles need to have a certain degree of strength and ductility to adapt to different installation conditions and resist the influence of the external environment. Aluminum-magnesium-manganese alloy is particularly suitable for making roof tiles with complex shapes and larger sizes due to its good mechanical properties.
5. Specifications and dimensions
The specifications and sizes of aluminum alloy roof tiles can be customized according to architectural design and construction requirements. Common shapes include flat plates, corrugated boards, corrugated boards, vân vân., and the sizes can be cut and processed according to the specific dimensions of the roof.
6. Environmental protection and recyclability
When choosing aluminum alloy roof tiles, you should also consider its environmental protection and recyclability. Aluminum alloy is a recyclable material that can be recycled after use to reduce the impact on the environment.
When selecting aluminum alloy specifications suitable for roofing tiles, multiple factors such as material, độ dày, surface treatment, sức mạnh, ductility, specification, kích cỡ, environmental protection, and economy need to be comprehensively considered.
