GF board is an inorganic, non-combustible board primarily composed of xonotlite. It possesses stable physical and chemical properties and is a semi-permanent material. It maintains no deformation and maintains essentially unchanged fire resistance even under long-term use at room temperature or in humid environments. GF board is lightweight, offers excellent thermal insulation, and is heat-resistant up to 1100°C. GF fireproof board is both an excellent fireproof material and a decorative material, compensating for misalignment during the installation of steel beams and columns. This ensures a flat surface, vertical elevations, and square corners after cladding, enhancing the aesthetics of interior decoration. GF board can be directly applied to interior decoration, such as spraying or gluing, and can also be tiled, meeting the decorative requirements of various locations. GF board can be sawed, planed, and nailed on-site, allowing for dry construction. It is unaffected by the season and can be interleaved with other construction processes. The entire process, including construction management, material storage, and site clearance and inspection, can be completed in one go. This streamlined and efficient process speeds up construction, saves labor, shortens construction schedules, and is unaffected by climate. GF board does not contain asbestos and does not produce toxic gases under high temperatures or fire conditions, making it a green and environmentally friendly building material.
GF boards have been used in key demonstration projects of the Ministry of Construction, including Jinan Oriental Lijing Building, Jinan Eiffel Garden, Jinan Weidong New Capital, Jinan Lupin International Plaza, Jinan Institute of Construction Engineering, Jinan Golden Real Estate, Qingdao Difeng Building, Qingdao Huayang Huigu, Xianyang Licai Tianxi, Laizhou Baidu International Hotel, etc., and have been unanimously recognized and praised by users.
