Commonly used door and window materials are wood, steel, aluminum alloy, plastic, glass and so on. Wooden doors and windows are easy to make and are suitable for manual processing. They have been widely used. Steel doors and windows have high strength, small sections, low light blocking, and fire protection. The steel doors and windows profiles used have been continuously improved to form a variety of product specifications. Ordinary steel doors and windows easy to rust, heavy weight, high thermal conductivity. Nowadays, the newly developed aluminum-leafed steel doors and windows, plated steel doors and windows, colored steel doors and windows, and hollow plastic steel windows have greatly improved the corrosion and energy saving performance of steel doors and windows, and have been promoted in new houses.

Aluminum alloy doors and windows are light, upright and exquisite, and have good sealing performance. They have been widely used in high-demand houses. However, the aluminum alloy has a large thermal conductivity, a poor thermal insulation and a high cost. At present, plastic aluminum windows made of materials with good insulating properties, such as plastics, can greatly improve the thermal performance of aluminum alloy doors and windows. Plastic doors and windows with good thermal performance, precision machining, corrosion resistance, is a promising type of doors and windows. At present, China's production of steel doors and windows cost is high, strength, rigidity and aging resistance still need to be improved, but with the development of the plastics industry, high-strength, anti-aging plastic doors and windows have reached the service life of more than 30 years, plastic doors and windows will be more and more The more you apply.

At present, no plywood shall be used to enter the door as required. Door locks shall be securely installed.
