Steel security doors are widely used in indoor and outdoor buildings. For the use of steel doors outside the normal use of a variety of uses of steel doors, the need for galvanized steel, the reinforcement using oxygen protection welding to strengthen the installation, the installation of waterproof threshold (or bottom seal), anti-theft, anti- High quality coating to suit the outdoor sun and rain in the harsh working environment.
The appearance of the steel door on the market is very similar to that of the anti-theft door. From the anti-theft performance, the standard anti-theft door steel plate is thick, the impact resistance is strong, the implementation of the national strong standard; and the steel door is the implementation of their own corporate standards, High-quality steel doors are currently widely used in hospitals, research and development centers, government offices, foreign offices and industrial plants. In the country, a lot of steel door manufacturers, products uneven, low market positioning, the main manufacturers to focus on the weight, while ignoring the importance of the quality of the product.
First of all, in the purchase of anti-theft security door, the dealer's business qualifications to be certified to see whether the operator holds the Public Security Bureau of technical management departments issued the "anti-theft security door certification."

Steel fire doors about more than 300 enterprises, centralized to the fire department management. China's economy continues to maintain high growth, the development of the door industry has provided the impetus. The state on the "implementation of the scientific concept of development" requirements and "scientific and technological innovation" system for the development of excellent door enterprises to create the conditions. At present should be to enhance their brand and image of the inflection point: to strengthen technology research and development efforts to expand the scale of production, improve the degree of modernization of production, participation in domestic and foreign market competition. At this time in the door industry to develop environmental labeling standards, to carry out environmental labeling certification is very timely and necessary to promote the entire industry to produce more environmentally friendly, truly energy-saving door product development.
