Fiberglass FRP Natural Daylighting Corrugated Sheet

FRP skylight sheet is usually called glass fiber reinforced polyester corrugated sheet, and the English abbreviation is FRP or GFRP. FRP daylighting sheet refers to a composite product formed by impregnating glass fiber mat with unsaturated polyester resin, and then gel curing. Compared with other materials in the past, FRP daylighting sheet has the characteristics of light weight, high strength and good impact resistance, especially its unique light transmittance. The light transmittance of 1mm thick FRP daylighting sheet can reach more than 85%, and more than 70% of the passing light is refracted light, which is much higher than ordinary architectural glass. The light through the daylighting sheet is uniform, which is extremely beneficial to the lighting of machinery processing, light industrial plants, stadiums, shopping malls and other buildings; it has significant lighting effects for building and breeding. In addition, FRP daylighting sheets also have excellent corrosion resistance and resistance. Atmospheric aging, simple design, convenient construction, optional colors and other characteristics.

Features of fiberglass FRP natural daylighting corrugated sheet:

1. It maintains stable performance in the range of -40℃-130℃, without high temperature softening high cold embrittlement. It can also be designed as a double-layer structure with better heat preservation effect.

2. Strong resistance to breakage and impact, which can block the impact of wind, snow and ice to the greatest extent, avoiding nail holes from swelling, cracking and water leakage.

3. Easy to clean, convenient to clean, no special care required.

4. The lighting velvet is astigmatic, the light is soft, and the light-by-light rate is maintained high, which can effectively block most of the ultraviolet rays.

5. In the event of a fire, the dense smoke in the room will be discharged after rapid combustion, which can reduce the casualties of fire personnel and will not produce droplets during the combustion process.

6. It has the characteristics of corrosion resistance, acid and alkali resistance.

Installation of FRP daylighting sheet

1. When fixing the FRP daylighting sheet, the pilot hole should be used. The size of the hole should be about 6-9mm of the screw diameter.

2, The FRP daylighting sheet is fixed by aluminum profile gusset, and it can be glued and sealed after being fixed. The position of the daylighting sheet is generally set in the middle of the span.

3. When the FRP daylighting sheet and the steel plate are overlapped, there must be an overlap of 200mm and two waterstops should be attached

4. When installing FRP daylighting panels, consider the expansion and contraction performance of daylighting panels.

5. The FRP lighting sheet is connected with the tapping screw, and there must be a cover plate between the two.

6. Fix the daylighting sheet between the screw and the FRP daylighting sheet. This can better waterproof and dustproof

7. After inserting the flashing washer into the screw, use an electric drill to lock it into the standard strip.

8. During the construction of FRP daylighting sheet, it is forbidden to step on the wave crest to avoid the daylighting sheet from cracking.

9. In the horizontal position of the FRP daylighting sheet, place a thick wooden board with a length of 1300mm and a width of 200mm, and step on it to carry out the guide holes and fixing screws of the daylighting sheet.

Tips for identifying the quality:

1. The appearance of the lighting sheet is bright and clean without wrinkles, the color is pure, no variegated color, pattern, no obvious bubbles, cracks, film warping and other impurities that affect the appearance, and the spacing of the ribs in the lighting sheet is uniform and no distortion.

2. The overall thickness of the daylighting sheet is uniform, and there is no thickness on the four sides and thinness in the middle. The uneven thickness of the lighting sheet will shorten the service life of the lighting sheet. The thick lighting panels on both sides should not be closely connected to the lighting sheet during the installation process, which will cause wind, water and dust to enter.

3. The method of identifying the thickness of lighting sheet: weigh the specific gravity of the lighting sheet.

4. The light transmission performance of the lighting sheet： the light is scattered through the lighting sheet, the light is soft and bright, and it can effectively block more than 99.99% of ultraviolet rays.

5. The lighting sheet and the color steel of the same specification are closely overlapped, the thickness of the section is uniform, and the sheet profile is the same as the color steel plate.

6. The lighting sheet used for a long time has no discoloration, no yellowing, no fiber exposed, no cracking.

7. Good toughness, no cracking when installing nails on the roof.

8. The lighting sheet has a complete range of specifications and colors, and different light transmittances are selected according to different design requirements.

9. The coefficient of thermal expansion and contraction of the daylighting sheet is close to that of the steel plate, and it will not leak water due to the cracking of the nailing place due to thermal expansion and contraction.
