Brief Introduction

Light transmission

The light transmission of FRP corrugated roofing Sheet is between 60-85%. Light through FRP corrugated roofing Sheet scatters and is mild. It will not form a light band so as to make the indoor brighter.

Weather resistance

The 23μm anti-aging film from Dupont covering on the surface of FRP roofing sheet improves its property of

UV resistance

The anti- ultraviolet adsorbing agent mixing in the raw materials absorbs 99.9% of ultraviolet ray of the visible light transmitted through the FRP sheets.This UV protection will help to prevent the dissolution and discoloration of the materials. The unique technology used in FRP roof Sheet makes the life span of the sheet up to over 15 years, probably 20 years ( a ten-year warranty is supplied).

Impact resistance

The strengthening fiber-glass materials criss-cross the structure of the products,which helps to improve the impact resistance of FRP sheet. When impacted by spalls or hails, they are hardly broken.

Corrosion resistance

The products resist various acids, alkalis and peroxides, especially suitable for application in the coastal areas and corrosive places.

Temperature performance

FRP roof Sheet is a kind of hot solid high polymer materials. It is designed for normal use in temperatures from - 40°C to120°C.

Temperature insulation

The coefficient of heat-conduction of FRP roof Sheet is 0.18kcat / mhr°C , only 1/4 of the glass. That is why it has a good property of temperature insulation.

Fire-retardant

Fire-retardant the fire-retardant of FRP roof Sheet is divided into ordinary gradeⅠ and gradeⅡ. The oxygen index of the gradeⅠof fire retardant is ≥32, the grade retardant is ≥26. It meets the standards of the fire brigade department.

Heat stability

FRP roof Sheet is a kind strengthening plastic of hot solid fiber-glass . Its coefficient of heat expansion is 2.2 x 10-5mm/mm/°C, only 2 times of metal materials. For this reason, when it matches with a metal sheet, the displacement is relatively small, not easy to leak.
