What is the material of grg ceiling? Grg ceiling material is based on high-quality natural modified gypsum, and high-strength alkali-resistant glass fiber and trace environmental additives are added. The surface of the product is smooth and white, and the whiteness is above 90. The surface of the material is smooth and delicate, and it can be well bonded with various coatings and decorative materials to form a decorative effect.
Grg ceiling material advantages:
1, the randomness of modeling makes it an architect who requires personalization, and its unique material composition is enough to resist the damage, deformation and cracking caused by the external environment.
2. Non-deformation and non-cracking-due to the low thermal expansion coefficient of gypsum, the dry-wet shrinkage is less than 0.0 1%, grg products are not affected by environmental cold, hot, dry-wet deformation, and their performance is stable and non-deformation. Unique fabric processing technology makes the product not crack and has long service life.
3. High strength and light weight-the bending strength of ——grg products reaches Mpa20-25. The tensile strength reaches the test of Mpa8- 15(ASTMD256-2002), and the weight of the standard board with a thickness of 6-8mm is only 6-9kg/m2, which can meet the requirements of large block ceiling partition and reduce the main weight and component load.
4.grg ceiling materials are mainly thin-walled, light and high-strength, which can adjust the humidity of indoor environment and achieve a comfortable living environment. It has high strength, high hardness and good flexibility, and can be made into any shape.
