Company Profile


Corporate tenet: provide state-of-the-art fire resistance and thermal insulation materials for all high-rise buildings, be committed to the revolution of walls, and produce  xonotlite artificial wood materials in the world, as well as xonotlite insulation panels, which are not only energy-efficient and heat-insulating, but also protective of equipment and conducive to improving process control.


The company is the hi-tech enterprise in China adopting the new technology of “pre-gelatinizing secondary high temperature and high pressure synthesis”, to produce high temperature resistant calcium silicate insulation materials. Due to the adoption of the pre-gelatinizing technology as well as the high-temperature and high-pressure steam synthesis at 400℃ or above, the obtained high-calcium silicate products are featured by high temperature resistance, and higher flexural strength compared with products with the same proportion. The highest heat temperature is up to 1,150℃, 100℃ higher than the heat-resistance temperatures of products currently produced using ordinary production technologies in China; the flexural strength is up to 0.7mpa, 0.2mpa higher than that of products with the same proportion. Thus, the service life of the product is prolonged, and its energy-saving effect is also improved. Thanks to such features as high heat resistance, high flexural strength, and non-deformation under long-term thermal erosion, the product can serve as a support for refractory equipment, protecting it and stabilizing the refractory body. In addition, because our company uses the 2.7MPa pressure of 400℃ superheated steam for synthesis, to achieve high-quality xonotlite compound bodies, which are then put into special processing. The plate produced in such a way has a volume density of 180-350kg/m3, a flexural strength of 1.5 MPa or above, a compressive strength of 2.5 MPa or higher, and the heat resistance of 1,000℃ or more; the thermal conductivity (at room temperature) is up to 0.036w/mk, and the water increase rate is greater than 98%. It is an excellent artificial wood material used for thermal insulation and fire resistance on external walls of buildings, and the performance indicators measure up to the most advanced level. This high technology of our company has obtained national patent (patent number: ZL201210251692.8、ZL201210251695.1、ZL201320598589.3.)


The company has a registered capital of 5 million yuan, being equipped with strong a technological force. We have been engaged in the production of xonotlite plates for decades, having accumulated rich production experience in research and development. The company has advanced large-specification hydraulic automatic plate production lines, with an annual production capacity of 40,000 cubic meters. The artificial wood materials produced by the company are also well received by the relevant organs and real estate developers. At the same time, the products have been largely applied in fire door core plates, steel structure fireproof boards, air ducts and flues in buildings for fire resistance and heat insulation. The ultra-light high-strength hydrophobic xonotlite fire plate is the best fireproof insulation plate for the external walls of buildings. It is bound to bring huge social benefits to the country and the ideal business benefits to customers. The calcium silicate products produced by the company are widely used in industrial furnaces in cement, metal smelting, petrochemical, machinery, electric power, and other industries, thermal insulation and building walls in thermal pipe networks, as well as fire resistance and insulation for steel structures and exterior walls, with remarkable energy-saving and firefighting effects, being highly favored by domestic and foreign customers. The company regards product quality as its life, constantly absorbing new technologies and adopting international advanced standards for production control. The company will contribute its efforts for energy conservation and fire safety in both China and the world, with high-quality and high-performance products.


Chairman of the Board Mr. Yu Fengcai and general manager Guo Liping sincerely invite friends to join hands with us create our mutual brilliance.
