corrugated UPVC/PVC roof sheet can be used for roofing of buildings, as roof panels, roof without additional insulation materials, and can achieve the effect of thermal insulation, because of its convenient construction can greatly shorten the construction period. Lightweight roof is more suitable for large-scale modeling of more complex steel roof. Aerated concrete lightweight roof panels in residential buildings and other civil buildings in the universal application. The aerated concrete has the advantages of light weight (1/4 ~ 1/5 of ordinary concrete, 1/3 ~ 1/4 of sintered clay brick), good insulation performance, saving steel, good machinability, So at the time as a new technology to promote the application, but because of its deformation, prone to cracks and other reasons, in the early 1980s has been basically stopped using the use of aerated concrete materials made of sheet metal
So what kind of material is made of lightweight roof panels?
Specifications: 830mm / any length, thickness: 2.0-3.0mm, weight: 2.5 --- 4.5 kg / square meters, effective use: 87%, for temperature: -50 ℃ -70 ℃, tensile strength: 29.4mpa, bending Strength: 45.6mpa, low temperature (-5 ℃ drop hammer impact): 10 times zero broken, for slope: 10 degrees -90 degrees, life: more than 25 years.
Scope: modern factories, fertilizer plants, sewage treatment plants, electroplating plants, power plants, breeding plants, markets, warehouses and other large industrial building roof and wall new and plant renovation project.
1, weather resistance, corrosion excellence - proven by practice, products in a variety of climatic conditions, have shown good weather performance, acid, alkali, salt chemical corrosion in the territory showed good corrosion resistance.
2, waterproof performance prominent - in the 15-90 degree slope roof building use free waterproof layer.
3, wind, earthquake - 90 degrees building facade decoration safe and reliable, can withstand 12 strong winds.
4, good fire performance - material resistant to burning grade B1, is a flame retardant material.
5, muffler, good insulation properties - porous foam core layer has a good silencer and thermal insulation properties.
6, large area, light weight - lightweight materials, reduce the construction load.
7, rich colors, durable and stable - fluorocarbon coating, rich colors, smooth surface, Naisuan Jian, not mildew, rain as new
8, toughness, high strength - than similar products have better toughness and strength.
9, easy construction - products can be directly nail, drill, saw, planing, easy to handle the facade and arc window and other special roof shape.
