How to choose aluminum sheet for roofing for sale Haomei?

As a new, composite, environmentally friendly and high-tech roofing waterproof material at the international advanced level, aluminum tile has gradually become one of the commonly used products in construction aluminum. The new type of aluminum sheet for roofing is a major innovation to the traditional roof waterproofing technology. It is a replacement product of conventional roofing waterproofing materials. The roofs of many ancient buildings are also repaired and built with aluminum tiles. Currently, there is a trend to replace traditional tiles, stainless steel and iron plates. Applicable to all kinds of building facilities. The color aluminum tile, as the name implies, is the coated aluminum tile. At present, the mainstream in the market is the polyester-coated aluminum tile. So how to choose specifications and models of the aluminum sheet for roofing for sale?

First of all, to choose aluminum tile, aluminum tile specification and model, we should look at the coating. The commonly used coating of aluminum tile is fluorocarbon coating, which is made of fluorocarbon resin with fluoroalkyne as the basic monomer, pigment, alcohol ester solvent and auxiliary agent. After the film is formed by high temperature grilling, the molecular structure in the coating is tight and has super weather resistance. Fluorocarbon coatings can be divided into traditional fluorocarbon coatings and nano-fluorocarbon coatings according to the surface film structure. It is especially suitable for the decoration and display of indoor and outdoor decoration in public places, commercial chains, exhibition advertisements, etc. Coating thickness of aluminum sheet for roofing: PVDF (fluorocarbon)>=25micron, gloss: 10-90%; coating hardness: greater than 2H; adhesion: no less than grade 1; impact resistance: 50kg/cm , no paint peeling, no cracks, Fluorocarbon is used for 30 years without discoloration and paint. Secondly, how to choose the aluminum sheets for roofing alloy and color? When selecting the alloy, the chemical composition of the aluminum alloy used for aluminum tile refers to the national standard GB/T 3190-2006 . According to the alloy composition, 1050 and 1060 belong to pure aluminum, and the aluminum content is above 99.5%; Good anti-rust function; 3004 also belongs to a series of aluminum-manganese alloys, with higher strength than 3003, excellent formability, good corrosion resistance, and requires parts with higher strength than 3003 alloy. 5052 is an aluminum-magnesium alloy with higher hardness. 3004 and 5052 are widely used in aluminum tiles. Of course, you can also choose to customize different color specifications and sizes. Third, the model selection of aluminum sheet for roofings. The conventional models of aluminum tiles include 100-type aluminum tile; 120-type aluminum tile; 150-type aluminum tile; Again, aluminum tile for sale specification selection: the common specifications of aluminum tile are 1.0mm aluminum tile; 1.2mm aluminum tile; 15.mm aluminum tile and 2.0mm aluminum tile; the most used are 1.2mm aluminum tile and 1.5mm aluminum tile, if it is ancient For building tiles, if you want to use it for a longer time, 2.0mm aluminum sheets for roofings are recommended.
