Common specifications and uses of corrugated aluminium sheet

Special-shaped corrugated aluminium sheets, typical specifications are as follows:
Depth: 18 mm from the lowest point to the highest point.
Ripple width: 76mm (3 inches) between each ripple.
Typical thickness range: 0.4mm - 1.20MM
Corrugated aluminium sheet for roofing has a wide range of uses, most of which are used for the coating of tanks and containers, but also for commercial cladding of buildings.
The material provided may be ordinary, plaster or have a minimum number of coloured surfaces. Common alloys are 1050 and 3003. These alloys can also provide a moisture-proof layer for factory applications, combining ionomers and polyethylene, which is common when insulating materials are used as metal sheaths.
The coatings of color coated aluminium coil sheet for roofing can be divided into polyester coated aluminium coil (PE) and fluorocarbon coated aluminium coil (PVDF). The polyester coatings formed by repeated baking on the surface of colour roofing sheet can form a solid continuous film with strong adhesion, which has protective decorative properties. It is an anti-UV ultraviolet coating. It can give colorful aluminium articles rich color, and has good gloss and smoothness, as well as superior texture and feel, can also increase the level and three-dimensional sense. It can protect objects exposed to the atmosphere and attacked by ultraviolet radiation, wind blowing, rain, frost and snow. Because of the effects of temperature difference, freeze-thaw cycle, corrosive gases and microorganisms, the coating can play a protective role. Especially suitable for interior decoration and advertising board.
Fluorocarbon coatings are PVDF resins, which mainly refer to homopolymer of vinylidene fluoride or copolymer of vinylidene fluoride and other small amount of vinyl fluoride monomers. In addition to the abrasion resistance and impact resistance in mechanical properties, it also shows long-term anti-fading and anti-ultraviolet properties especially in bad weather and environment. After high temperature barbecue, the molecular structure of the coating is compact, and it has super weatherability. Fluorocarbon coatings can be divided into traditional fluorocarbon coatings and nanofluorocarbon coatings according to the surface film-forming structure.
