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. Iron fences shall be installed on the outer windows on the ground floor, the public walkway windows on the floors, and the bright lights on the entrance doors; the door and window glass shall be smooth in surface, full of putty, and pasted. firm.

The spectrum of LED plant lights can be adjusted according to the needs of different plants to provide the most suitable lighting conditions for plant growth. The newly designed plant lights also focus on appearance and user experience. They typically have a simple, stylish exterior design that harmonizes with the interior environment and is easy to install and operate. Some plant lights also have adjustable poles and lamp heads designed to better illuminate the plants.
The newly designed plant grow light is a special lighting device designed to provide indoor plants with the required light conditions to promote their growth and healthy development. This plant grow light uses advanced LED technology and has the following features:
1. Spectrum adjustment: grow lights can provide the full spectrum of light, including red, blue, yellow and other different wavelengths of light. This can adjust the color and intensity of the light according to the needs of different plants to promote their photosynthesis and growth.
2. High efficiency and energy saving: LED technology has the characteristics of high efficiency and energy saving, compared with traditional fluorescent lamps or incandescent lamps, plant lamps can provide more light intensity, while consuming less energy, reducing energy waste.
3. Long life: LED lamps have a long service life, generally up to tens of thousands of hours, more durable and reliable than other lamps.
4. Easy to operate: led grow lightss are usually equipped with an intelligent control system, which can be adjusted and timing switched by mobile phone App or remote control. Users can customize the brightness, color and working time of the light according to the needs of the plant.
5. Beautiful design: The newly designed plant lamp pays attention to the aesthetic appearance, the shell is made of high-quality materials, the appearance is simple and fashionable, and is suitable for various indoor environments.
