CAMELSTEEL will analyze the advantages and disadvantages of some colour GI roofing sheet waterproof construction plans.
1. Traditional construction way.
Waterproof layer construction: polyester nonwoven+ sun-proof coating.
Construction way: Pave polyester nonwoven while painting coating. And then paint sun-proof coating on the cloth, followed by painting sun-proof coating again after it takes shape.
Disadvantages: There are few plants which can produce special waterproof coating or polyester nonwoven in the market, thus construction units mostly choose normal waterproof coating and nonwoven for replacement. Thus the waterproof layer can loss its waterproof effect very soon.
2. Latest construction way.
Waterproof layer construction: self-adhering layer+metal aluminum foil.
Construction way: Uncover the barrier film and paste it on the colour GI roofing sheet.
Advantage: Convenient construction and low construction costs. It can totally obstruct color steel tile from contacting with air, so as to achieve water resistance and corrosion resistance.
Disadvantage: Construction units usually do not construct following normal construction ways or do not construct completely, which leads to roof temperature difference and decrease in service time of color coated tile.
