Haicheng Dadeguang Fire Door Industry Materials Co., Ltd. was established in August 2009. It is located in Haicheng Economic Development Zone, Anshan City, Liaoning Province. It covers an area of ​​70,000 square meters and currently has more than 200 employees. It is a professional " A high-tech enterprise in the magnesium building materials industry. The company focuses on the research, development, production and sales of "green building materials" and has made great achievements in the field of new energy-saving building materials. Since the supply of raw materials comes from Huafeng Magnesium Industry, product quality control and technological innovation control are firmly grasped in our own hands, and with such unique resource advantages, after years of operation, Dadeguang has formed a large-scale industrial chain of magnesite products. Development brings full play to the advantages of regional resource. In 2013, the company was rated as a high-tech enterprise. In 2015, the company participated in the promulgation and implementation of the "Magnesite Fireproof Door Core Panel Industry Standard" (JG/T470-2015). He has successively established a joint research center for green magnesium building materials industry, academia and research with Qinghai Salt Lake Institute of Chinese Academy of Sciences, Liaoning University of Science and Technology, and Shenyang University of Chemical Technology, and has become the executive vice president unit of Liaoning Building Insulation Association and the vice president unit of China Magnesium Association.

The company's main products include glass magnesium boards, magnesium wall panels, glass magnesium floors, carbon fiber-based flexible multi-function fireproof decorative panels, magnesium oxide exterior wall fire insulation panels, magnesium oxide foam door core panels and other series of products. Many of these products won the first prize of Anshan City Science and Technology Progress. Many magnesium building materials such as demolition-free building forms are widely used in many fields such as high-speed rail EMUs, Leishenshan Hospital, interior decoration, and industrial factory steel structure fire protection and maintenance. The product's green, environmentally friendly, formaldehyde-free, radiation-free, fire-resistant and flame-retardant properties have become the preferred in the modern construction field.

The magnesium oxide exterior wall fire insulation board produced by the company meets the national A-level fire resistance standard, has a thermal conductivity coefficient of 0.55, and has a good insulation effect. It is an ideal product for building exterior walls. In 2011, the company obtained the registration qualification for magnesium oxide building insulation materials in Hebei Province, and signed and delivered a 300,000 square meters A1-level insulation project of building exterior walls in Qinhuangdao City.

Magnesium oxide foam door core panel is a new generation of fire-resistant filling material. It has the advantages of non-combustible, non-toxic, radioactive, fire-resistant, corrosion-resistant, and good thermal and sound insulation performance. It meets the requirements of the new national fire door standard "GB12955-2008". After inspection by the National Fixed Fire Extinguishing System and Refractory Component Quality Supervision and Inspection Center, the magnesium oxide foam door core plate produced by our company has met the combustion performance A1 requirements stipulated in "GB8624-2006" and the materials produced by "GB/T20285-2006" Smoke toxicity hazard classification AQ1 level requirements.

High-quality products have gained market recognition and customer trust. Products are widely sold in Beijing, Tianjin, Shaanxi, Heilongjiang, Jilin, Shandong, Hebei and other places. The company has signed a centralized procurement contract with AsiaSaHerda Asia Pacific, responsible for supplying its door industry groups including Yingkou Panpan and Beijing Tianming Leading companies in the industry, such as Door Industry, Yantai Huasheng Door Industry, and Harbin Xinami Door Industry, have established a good brand reputation in the industry.

Under the leadership of Chairman Fu Hongwei, the company is committed to the comprehensive utilization of tailings, tailings and waste slag with the business philosophy of "returning the earth to a pure land and returning the sky to a white cloud", and has become an influential new building material in the Northeast region. enterprise. We will take revitalizing national industry as our mission and develop enterprises with science and technology as our journey, we will go through wind and rain, forge ahead, overcome obstacles, and never forget our original aspirations.
