colored corrugated roof sheet with high corrosion resistant in stock

The high weatherability rein used for PVC corrugated sheet has outstanding waterproof property, let alone water penetration through minor holes.

Stable shape

The expansion rate of plastic steel tile is 4.93Í10/°C. They can stay stable whatever the big change of temperature is, the tiles can adjust themselves to the property of expand with heat and contract with cold.

The maximum value of 1.00mm thickness plastic steel tiles is only 1.85kilogrammes for every one square.

The main material of PVC corrugated sheet is a kind of flame retardant material, with the Refractoriness level reaching level B1.

The thermal conductivity for Honglu PVC corrugated sheet  is 0.325W/m.k, which is only 1/3 of clay tiles about 0.325w/mk, 1/5 of thick cement tiles and 1/2000 of color steel tiles with 0.05mm thickness.

Resistance Against Lashes

Under the normal temperature (23°C± 2°C), there will be no crackle or hole on the surfaces of Honglu PVC corrugated sheet when they are hit by a 1kg steel ball falling down from the 1.5m height.

Excellent Anticorrosive Property

The body and surface synthetic resin of Hong Lu PVC corrugated sheet has a terrific anticorrosive property. Its property won’t be decreased after be hit by chemical substances such as acid substances, alkaline substances and chemical compounds. It is perfectly fit for chemical factories, high salt spay corrosion seaside areas and serious aerosol pollution areas.

Good Sound Insulation Effect

The material that PVC corrugated sheet used has good sound insulation effect. It can effectively filter 35% to 50% of the sound .

The material that PVC corrugated sheet used has good light penetration .And the rate of light permeation is 20%-30%, increasing indoor daylighting,thus saving the electricity energy.

The material that PVC corrugated corrugated sheet used can be recycled and reused .when the material was used , it can be deeply processed to be its accessory products (like diesel oil).

Plastic has excellent insulation, and does not conduct electricity, which increase the safety of building and the dwellers.
