China factory direct sale PVC anti-corrosion plastic roof sheet

Feature
• Anti-corrosion
• Nanxing PVC plastic 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 rainprone areas and coastal use, the effect was particularly significant.

• Waterproof
• Nanxing PVC plastic 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 Resistance
• Nanxing PVC plastic 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 ≥ B1 grade.

• Heat Insulation 
• Nanxing PVC plastic 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 PVC plastic roofing sheet can still achieve the best thermal insulation properties.

• Sound Insulation
• The tests prove that: in suffering heavy rain, high winds the impact of outside noise,       ZhongXingCheng PVC plastic roofing sheet has a good absorption of the noise effect,noise down 30dB than color steel tile.
