GRG， I.e Reinforced glass fibre plasterboard 。 It is a kind of special reinforcement with superior natural improved gypsum as the base material and gypsum added Glass Pre cast plastic new decorative material made of fiber and environmental micro additives.

Drawings/photos - → print drawings as 1:1 sample - → copy on the plywood for marking - → soft clay molding - → clay mold repair/check the original scheme - → clay mold flat Nail mold frame - → silica gel mold turnover - → semi-finished GRG pre casting - → semi-finished product repair defect rectification - → semi-finished product as base frame - → silica gel mold turnover - → finished GRG production - → curing and drying - → packaging and transportation. (Note that in order to ensure the quality, the positioning of the silicone mold is very important each time, and the size is accurate)

2） GRG characteristics
3） 1. No deformation: since the GRG main material gypsum has no corrosive effect on the glass fiber, and the shrinkage rate after drying is less than 0.01%, it can ensure that the product has stable performance, durability, no cracking, no deformation, and long service life.
IV)
5） 2. Light weight: The density of GRG is 1800Kg/m3, and the weight of 10mm thick GRG board is about 22Kg per square meter, which can reduce the weight of the main building and the load of components.
VI)
7） 3. Height and stable performance: GRG products with high strength and 20mm thickness have a bending load strength of more than 1200N, which exceeds the breaking load strength of decorative gypsum board by more than 10 times of the national standard of 118N. The processed GRG product has a low coefficient of thermal expansion, its drying shrinkage is less than 0.1%, and its performance is stable. It will not be deformed, sagged, expanded, etc. due to changes in ambient temperature and humidity.
8） 4. Flexibility&flexibility (strong plasticity): GRG products adopt special pre casting processing technology. The material itself has very good bending resistance, tensile elongation, so GRG products have flexible and flexible plasticity.
IX)
10） 5. Breathing=moisture-proof. GRG plate is a kind of plate with a large number of micropores. In the natural environment, the porous body can absorb or release water. When the indoor temperature is high and the humidity is low, the board gradually releases the moisture in the micropores; When the indoor temperature is low and humidity is high, it will absorb moisture in the air. This release and respiration form the "breathing" effect. This cycle of moisture absorption and release plays a role in regulating the indoor temperature, creating a comfortable microclimate for the working and living environment.
XI)
12） 6. Fire prevention: GRG material belongs to * * * material. In case of fire, in addition to being flame retardant, it can also release moisture equivalent to 15% to 20% of its own weight, which can significantly reduce the temperature of the fire surface and reduce fire losses.
XIII)
14） 7. Environmental protection: GRG products have no smell, and the standard of Class A decorative materials belongs to green environmental protection materials.
XV)
16） 8. Good acoustic effect: the test shows that the air dry specific gravity of GRG is 1.75, meeting the professional acoustic reflection requirements. Through good modeling design, a sound absorption structure can be formed to achieve sound insulation and absorption.
XVII)
18） 9. Short processing cycle: it only takes 1 hour for GRG products to be de filmed, and 4~8 hours for special treatment and drying.
19） 10. Convenient installation and construction: GRG products can be produced in large blocks according to any shape designed by the designer. The hoisting and splicing technology is adopted on site, which has good processing performance, rapid and flexible installation. After a large area of seamless and tight splicing, a relatively perfect shape and decoration effect is formed.
XX)
21） 11. Good decorative effect of material surface: GRG product has a fine and smooth surface, which can effectively bond with various coatings and other veneer materials (wood veneer, fabric, etc.) to achieve the desired decorative design effect. It is not easy to be eroded by the external environment, and can largely replace stone, wood and other decorative materials.
XXII)
23） 12. Good acoustic effect: suitable for sound theaters, cinemas and multi-function conference halls.
XXIV)
25） 13. Suitable for all places with strict requirements for environmental protection.
XXVI)
27） 14. Adjusting indoor temperature: applicable to hotels, reception halls, leisure spaces and private rooms.
XXVIII)
29） 15. Arbitrary modeling: applicable to modeling theaters, cultural interior decoration and other indoor modeling bodies.
XXX)
31） 16. High strength: ceiling that can be used as wall and people can walk on the back
XXXII)
33） 17. Non combustible, flame-retardant and fireproof: applicable to KTV, nightclubs, bars, flammable places, high hotels and high specification venues.
XXXIV)
35） 18. Easy to finish: cultural buildings, private entertainment clubs, high-class villas, and buildings with high acoustic requirements.
XXXVI)
37） 19. Mould proof, moisture-proof and anti-static: laboratory and wet places.
