metal roofing sheets
FRP sheets are made of fiberglass and polyester resin and continuously molded by machine.
They are characterized by high-light transmittance, light-weight, high-strength, corrosion resistance, impact resistance, anti-ultraviolet, anti-static, heat preservation and insulation, accurate section dimensions and controllable cutting length. They can be used with various profiling panels and galvanized sheets.
The products resist various acids, alkalis and peroxides, especially suitable for application in the coastal areas and corrosive places.
Temperature performance and insulation
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. The coefficient of heat-conduction of FRP roof Sheet is 0.18kcat / mhr°C , only 1/4 of the glass.
Fire-retardant the fire-retardant of FRP roof Sheet is divided into ordinary grade
I 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.
