Fiberglass roof sheet is a glass fiber-reinforced composite sheet, are of thermosetting. Composite material itself determines the objects belonging to the non-uniform optically. Since the wavelength of visible light is much greater than the diameter of the glass and the distance between adjacent two fibers is very small. Therefore, to produce multiple scattering, so dazzling sunlight into soft affinity human eye. Workers for a long time in the room working of the human eye is not tired, and energy saving. Coupled with the lighting board surface with a special UV film UV agent is added in the raw material greatly extended service life.
Fiberglass roof sheet commonly used in industrial plants roof and wall lighting, agriculture vegetable greenhouses, public stadiums roof lighting, warehouses, greenhouses, railway stations, docks, airports, commercial buildings, steel structures, and many other leading lighting special requirements of building fire-retardant anti-corrosion insulation and other places.
Type750, 840, 820, 980, 950, 900, 475, 760, and 1m-1.2m wide and more than hundred kinds of flat plate.
Fiberglass roof sheet consist of high-performance membrane, high-quality polyester, and glass fiber reinforced composition.
It is a glass fiber-reinforced composite sheet of thermosetting.
(1) translucent: FRP lighting board transmission rate of up to 89%, glass phase deceased mother with the United States.
(2) impact resistance: FRP lighting board impact strength is 250-300 times that of ordinary glass, 30 times that of same thickness of acrylic sheet is tempered glass 2-20 times, with two meters below 3kg hammer falling and no cracks, there "no broken glass" and "ring of steel" reputation.
(3) anti-UV: Filter out the sun's ultraviolet rays 99.
(4) light weight: Accounts for only half of the glass, saving transportation, unloading move, the cost of installing and supporting frame.
(5) flame retardant: The national standard GB50222-95 confirmation, divided into two and a flame retardant.
(6)bendable: To follow the design site use of cold-formed, the installation into the arched, semi-circular roof and windows. Minimum bend radius is 175 times the thickness of the plate using, also bending
(7) high strength, durability up to 15 - At least 20 years. Preservative.
(8) stability, between -30 ºC -130 ºC without any impact on this product.
