Description

Technical Field

[0001] The utility model relates to the field of steel doors, in particular to paint-free, highly weather-resistant and environmentally friendly steel doors. Background Art

[0002] Steel doors are widely used indoors and outdoors in various buildings. Steel doors used outdoors are normally used for multiple purposes. They need to be made of galvanized steel plates, and each reinforcement should be welded and reinforced with oxygen shielded welding, and equipped with waterproof thresholds (or bottom seals), anti-theft pins, and high-quality UV-resistant coatings to adapt to the harsh working environment of outdoor sun and rain.

[0003] The appearance of steel doors on the market is very similar to security doors. In terms of anti-theft performance, standard security doors have thick steel plates and strong impact resistance. They implement national standards, while steel doors implement the company's own standards. High-quality steel doors are currently widely used in hospitals, R&D centers, government office buildings, foreign company offices and industrial plants. Currently, steel doors are mainly made of stainless steel, which is easy to conduct heat and has low weather resistance. When temperature control equipment is running indoors, steel doors will exchange the indoor temperature with the outdoor temperature, affecting the temperature control effect of the temperature control equipment, increasing energy consumption, and insufficient environmental protection. For this reason, we propose paint-free, highly weather-resistant and environmentally friendly steel doors to solve the above problems. Utility Model Content
