1. PRODUCT DESCRIPTION
Wave layer: 3 layers 11 waves INNOVA roofing sheet corrugated from steel by galvanizing technology hot dipped galvanized aluminum painted color coating according to American standards ASTM – A653, ASTM – A792, or Japanese industry standard JIS G3312. 11-layer civil 3-layer roofing sheet, effective size 1000mm/ Product size 1070mm, positive wave height of 18±1mm increases the hardness of the steel. Various colors of corrugated iron increases the aesthetics of the construction.
PU layer: 3 layers 11 waves INNOVA roofing sheet choose hard PU series linked together by hydrogen bonds. Main circuit straight, unbranched, closely linked without slipping on top of each other gives PU a high elastic modulus and do not disperse in the air, do not cause environmental pollution.
This PU layer is weather resistant. Including not oxidized, resistant to sunlight, ozone and normal weather conditions. The standard PU thickness of the product is from 16mm to 20mm ± 2, PU thickness tolerance ± 1m.
PP paper/ Alufil paper layer: The innest layer uses PP paper or Alufil silver paper increase the durability of the product, minimize the infestation of insects and some other animals.
