GRG has been used in more than a hundred large-scale decoration projects with complex shapes and diverse functions, such as the National Center for the Performing Arts, the Water Cube, and the Shanghai World Expo Center. The Huzhou Grand Theater also uses GRG materials. This material can be made into various flat panels, various functional products and various artistic shapes. It is the most popular updated product in the international building materials and decoration industry.
Under normal circumstances, architectural designers often recommend suspended ceilings used in industrial and commercial buildings to resist high impact and increase their stability.
Extended information
GRG performance
Rich options are available. GRG products using pre-cast processing technology can be customized with any artistic shapes such as single-curved surface, double-curved surface, three-dimensional cladding, various geometric shapes, hollow patterns, relief patterns, etc. to give full play to the design.
High strength and light weight. The bending strength of GRG products reaches Mpa20-25 (ASTMD790-2002 test method). The tensile strength reaches Mpa8-15 (ASTMD256-2002 test method, and the weight of a 6-8mm thick standard plate is only 6-9kg/m?, which can meet the needs of large-plate ceiling division while reducing the main body weight and component load. < /p>
No deformation or cracking. Due to the low thermal expansion coefficient of the main material gypsum and the dry and wet shrinkage rate of less than 0.01%, GRG products are not affected by cold, hot, dry and wet environmental deformation, and have stable performance and no deformation. The unique cloth fiber processing technology makes the product crack-free and has a long service life.
Acoustic reflection performance. GRG has good sound wave reflection performance. Tested by Tongji Acoustics Research Institute: 30mm single GRG board weighs 48kg. The reflection coefficient R≥0.97 meets the requirements of professional acoustic reflection and is suitable for acoustic halls such as grand theaters and concert halls.
It is mainly characterized by its thin wall, light weight, high strength and non-combustibility (Class A fireproof material). ), and can adjust the humidity of the indoor environment to achieve a comfortable living environment. Its high strength, high hardness and good flexibility can be made into any shape.
