GRG Introduction
GRG (Glassfiber Reinforced Gypsum) is a high-performance composite material used to create decorative panels, artistic moldings, custom-shaped components, and intricate designs. It is widely applied in interior and exterior decoration, combining personalized aesthetics with functional practicality.
Why choose GRG?
Lightweight yet high-strength, with precise shaping capabilities
GRG weighs only 60%-70% of traditional gypsum (approx. 1200-1400kg/m³), with a flexural strength ≥10MPa and impact strength ≥3kJ/m². Reinforced by fiberglass, it can form complex curved components as thin as 5-8mm while offering superior crack resistance. Ideal for high-precision decorative applications—such as theater domes, artistic reliefs, and custom ceilings—GRG is the premier choice for blending artistic design with functional performance in interior spaces.
Eco-friendly and fire-resistant with outstanding safety performance.
GRG is made from natural gypsum, 100% recyclable, and achieves Class A1 fire rating (non-combustible) per GB8624-2012. It releases no toxic fumes when exposed to fire, with a fire resistance rating exceeding 2 hours. Featuring neutral pH and zero radioactive emissions, it complies with green building certifications (e.g., LEED, WELL), making it ideal for hospitals, schools, exhibition centers, and other spaces demanding strict eco and safety standards.
Excellent acoustic performance with versatile decorative effects
GRG features customizable micro-perforated surfaces that, when combined with professional acoustic design, achieve a Noise Reduction Coefficient (NRC) of 0.6-0.8—making it ideal for acoustically sensitive spaces like concert halls and conference centers. Its surface accommodates spray finishes, gold leaf application, stone/wood grain effects, and seamless integration with LED lighting, metal inlays, or fabric panels, delivering both functional performance and aesthetic excellence.
Prefabricated modular design for fast and easy installation
GRG utilizes factory prefabrication with mold precision of ±0.3mm, incorporating digital modeling and 3D printing for mass production of complex designs. On-site installation employs dry-hanging with light steel frames and embedded connectors—each panel requires only 10-15 minutes for assembly, boosting efficiency by 50% compared to traditional wet construction. With near-zero dust or waste, it’s ideal for time-sensitive projects like commercial complexes and hotel lobbies.
