UPVC corrugated roof sheet, adopting advanced facilities and
technology from Europe, is made of synthetic resin (ASA) with
prominent weatherability. It remains stable in color and physical
properties under ultra-violet radiation, dampness, heat, chillness
and impact. It is widely used in workshop, warehouse, housing and
various permanent roofs with many years application history in many
Specifications (Unit: mm)
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.
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
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.
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
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
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
One standard piece of roof sheet weighs 1.87-6.0kg per square
With China Certificate of Environmental Labeling, this product
proves no radiation, volatilizable materials and pollution. What’s
more, it can be completely recycled.
