Roofing sheets are plates that may immediately withstand roof hundreds. The roofing sheet is positioned at the roof of the residence and is commonly made from metal consisting of aluminum magnesium manganese or alloy, so it's also known as as aluminium roofing sheet. Aluminum-magnesium-manganese sheet alloys for roofing generally undertake the Coil covered method, which has the advantages of good shade manipulate, uniform film, excessive first-rate stability and environmental protection. The sort of coating normally used PVDF fluorocarbon paint containing more than 70% of fluorocarbon resin.
The extremely good functions of aluminium roofing sheets are:1, wonderful climate resistance and anti-corrosion.Validated via practice, the aluminum roofing sheets have established top weathering overall performance beneath a diffusion of climatic conditions, showed precise corrosion resistance in the acid, alkali, salt chemical corrosion environment.2, terrific water-resistant performance.No water resistant layer is to be had in 15-90 diploma roof constructing.Three, The wind and earthquake resistance.Ninety tiers building facade ornament secure and dependable, capable of resist 12 robust winds.Four, properly hearth resistance overall performance.The material is hearth-resistant grade B1, is a non-flammable fabric.Five, splendid silencer and heat insulation performance.The porous foam middle has desirable noise attenuation and heat insulation residences.6, large place and light weight.Light-weight materials to reduce the development load.7, rich colours, lasting stability.Fluorocarbon paint coating, rich colors, clean floor, acid and alkali resistant, no mold.8, excessive longevity and electricity.Higher than similar products with longevity and strength.9, handy production.Products may be without delay nailed, drilled, sawed, planed and may be easily handled with special roof shapes along with facades and arc windows.
