ASA resin UPVC corrugated roof sheet T980
Shengyu UPVC corrugated roof sheet made from PVC and synthetic resin ASA (Sabic)which prevents roofing materials from discoloring. T980 roof sheet is light, solid, tough, weatherable, resistant to acids, fungi and humidity with prominent quality. It remains stable in physical performance of -40ºC to 80ºC.it is ideal roof material for carport, warehouse, industry park building.

Prominent weather resistance
As top layer material, ASA engineering resin is extraordinarily suitable for outdoor use. Even exposed to ultra-violet radiation, dampness, heat, chillness and impact, the products remain the stability of color and physical properties. Tests held in Aging Test Center of Arizona and Florida prove that is less than △E 5 within 10 years.
Shengyu plastic roof sheet passes 6,000h aging test by China National Test Center for Chemical Building Materials and its result △E＜4.
High impact strength and resistance to extreme climate
Shengyu UPVC corrugated roof sheet is tested by falling sphere impact test,( a 1kg steel ball falls freely from 1.5 meters high on sheets ) which proves no crack. Tested by ten cycles of freeze and melting, it proves no swelling, frothiness, peeling-off or crack.
Shengyu UPVC corrugated roof sheet, its heat conduction modulus is 0.325 W/m. K, which equal 1/3 with that of 10mm thickness clay sheets, 1/5 with that of 10mm thickness cement sheets, 1/2000 with that of 5mm thickness color steel sheets.
Excellent anti-corrosion performance
Shengyu UPVC corrugated roof sheet, its surface layer (ASA resin) has great performance in anti-corrosion test, which will not decline by erosion of rain and snow. ASA resin is resistant to many chemicals such as acid, alkaline, salt, etc. Therefore, it is suitable for outdoor application in costal area with serious salt fog corrosion and heavy air pollution.
The surface of roof sheet is dense and smooth, which has the same effect as lotus leaves. It doesn’t absorb dust and can be easily cleaned by rain.
Excellent anti-load performance
Shengyu UPVC corrugated roof sheet has strong capacity for heavy bearing. The test, conducted by Shanghai Municipal Building Material Component Quality Supervision and Test Station, proves that there is no crack in condition of 800mm supporting span and 150kg applied load.
One standard piece of roof sheet weighs 1.87-6.0kg per square meter.
With China Certificate of Environmental Labeling, this product proves no radiation, volatilizable materials and pollution. What’s more, it can be completely recycled.
1.UPVC(ASA) rooing sheets are applicable to roof pitches from 8°to 22°,with purlin span no more than 800mm.
T980 roof sheet are applicable to roof pitches from 6°to 22°,with purlin span no more than 1200mm.
2.Thermal insulating material can not be used directly under the sheet.
Please use a ladder or other required facilities during installation.
Please don’t stand between two purlins during installation.
For a gabled roof,sheets on each side should be installed at the same time with the ridge tile.
Installation is not recommended to be carried out at the temperature below -5℃.
Install by professional roofers to ensure the quality of installation.
Horizontal overlap by one wave and vertical overlap no less than 100mm.
The roofing sheets and wall cladding can be fixed by supplied hooks or self-tapping screws.
For every sheet,two sets of hooks should be fixed properly on one purlin, passing through the wave crest.
Every wave crest at vertical overlapping area should be fixed to the purlin by hooks,and reinforcing method should be taken in areas with heavy wind.
For wall claddings,the overlaps between two purlins should be fixed by two rivets.
Rubber cushions should be used under the sheet if fixing by hooks,the screw nuts should be tightened properly,not over-tight.
6.Roofing sheets should be cut by toothless saw.
Using electrical drill to drill holes.
Please make sure the sheets have been put correctly on purlins before drilling holes.
The hole diameter should be 2mm wider than that of hook mandrel.
Please use PVC glue to seal for mis-drilled holes.
8.Storage and Handling
The sheets should be stored on a plane stable, which should be longer than the sheet.
Shorter sheets should be put on longer sheets to avoid the deformation.
Don’t stack different profiles of sheets together.
Please store the sheets in the shade.
Avoid breaking,rubbing or scratching the surface during handling.
