3 layer anti corrosive composite upvc corrugated roofing sheet   Features:

The product is made of foreign advanced technology specifically for the plant where located in corrosive acid rain areas and re-designed a new generation of permanent roofing materials.
 
The product uses two or three-layer co-extrusion technology, a process completed, each layer materials have their own features, which surface materials for ultra-weather resin, to ensure product durability and resistance to chemical corrosion; intermediate materials for just a good material toughness special to ensure the strength at the same time, increase the rigidity; the underlying material is white ductile material, in order to increase the plant a sense of space and light intensity. Three kinds of different materials to give the product their own features, and the organically combined to make a new generation of anti-corrosion compound APVC sheet of corrugated sheet to solve the product durability, corrosion resistance, small rigidity, a sense of space and aesthetic issues.
 
Excellent corrosion resistance   
3 layer anti corrosive composite upvc corrugated roofing sheet  in the long term against acid, alkali, salt and other corrosive chemicals. Experiments prove that: In the salt, alkali and 60% following a 24-hour soaking in acid, no chemical reaction. Very suitable for acid rain-prone areas and coastal use, the effect was particularly significant.
Excellent weathering performance 
3 layer anti corrosive composite upvc corrugated roofing sheet 's surface materials is co-extruded in ultra-weather surface layer resin to ensure the durability of products (for 15 years in quality assurance).
Fire-retardant
3 layer anti corrosive composite upvc corrugated roofing sheet  is a flame retardant materials, through the national fire authority of the department according to GB8624-2006 standards for testing, fire safety performance ≥ B grade.
Good Sound insulation 
The tests prove that: in suffering heavy rain, high winds the impact of outside noise,   3 layer anti corrosive composite upvc corrugated roofing sheet has a good absorption of the noise effect, noise down 30dB than color steel tile.
Excellent thermal insulation properties   
3 layer anti corrosive composite upvc corrugated roofing sheet  ’s thermal conductivity coefficient is  0.325w/mk, clay tile is about 1 / 310, cement tile 1 / 5, 0.5mm thick color steel tile 1 / 2000. Therefore, without considering the case of insulation layer increases, the Hongbo APVC Anti-corrosion Complex Corrugated Sheet can still achieve the best thermal insulation properties.
3 layer anti corrosive composite upvc corrugated roofing sheet  e with good bearing capacity. In the lower temperature region, even if the roof of perennial snow, 2mm Anti-corrosion Complex Corrugated Sheet does not produce the phenomenon of surface damage and fracture. Been tested, in the case of support spacing 800mm, load 100 kg, sheet will not produce cracks and damage.
Excellent water resistance
3 layer anti corrosive composite upvc corrugated roofing sheet  select High weatherability dense and do not water-absorbent resin  ,there is no pore water seepage problem, at the same time with our own patented technology accessories, completely solved the problem of seepage in screw holes
Impact resistance & Good resistance to low temperature performance
APVC Anti-corrosion Complex Corrugated Sheet with a strong ability to withstand external impact. The test 1 kg steel ball from 3-meter high free-fall does not produce cracks, low temperature impact performance is also very significant
Excellent insulation
3 layer anti corrosive composite upvc corrugated roofing sheet  is one insulation products, will also be intact in an accident discharge, offer better protection at Ray-prone areas to replace metal tile
Environmental
3 layer anti corrosive composite upvc corrugated roofing sheet   does not contain asbestos and radioactive elements, and recyclable, in full compliance with the green environmental protection requirements
