It can also be partially made of glass, yarn or hundred pages, such as the above glass and the lower hundred pages.
Third, the purchase of plastic steel doors and windows:
Plastic steel doors and windows are a new generation of door and window materials, which are rapidly replacing because of their high wind pressure resistance, air tightness and water tightness, small air and rain penetration, low heat transfer coefficient, heat preservation and energy saving, sound insulation and heat insulation, and aging resistance. Steel windows, aluminum alloy windows.
1. Manufacturing of plastic steel doors and windows. Plastic steel doors and windows are generally manufactured in the factory with special cutting and welding equipment for plastic steel doors and windows. It is semi-automatic and automated, and the quality can be guaranteed.
2. The structure of plastic steel doors and windows. Plastic steel doors and windows are made of special Western-style rigid polyvinyl chloride (PVC) plastic profiles, plus off-duty hardware. The profile is a porous cavity, and the main cavity is provided with inner liner steel made of cold-rolled steel plate to improve the strength of the plastic steel door and window. The wall thickness of the profile should be above 2.5 mm.
3. Precautions for purchasing plastic doors and windows.
(1) Pay attention to surface quality. The color of the plastic profile on the surface of the door and window is blue-white or ivory white, clean, smooth and smooth, no scratches or bumps on the large surface, and no welding or breaking of the welded joint. A good quality plastic steel door and window surface should have a protective film, and the user should tear off the protective film before use.
(2) Do not buy cheap plastic steel doors and windows. Good plastic steel doors and windows have high quality from plastic quality, lining steel quality and hardware quality, and the service life can reach more than ten years. The profiles used in cheap plastic steel doors and windows have a calcium carbonate content of more than 50%. The additives contain lead salts, which have poor stability and affect human health. The lining steel is a hot-rolled plate, the thickness is not enough, and some even have no lining steel. The glass and hardware are also inferior products. The service life is only two or three years.
(3) Pay attention to glass and hardware. The glass should be flat and waterless. The glass is not in direct contact with the plastic profile, and the sealing bead is in close contact with the gap. The hardware is complete, the position is correct, the installation is firm, and the use is flexible.
Fourth, aluminum alloy doors and windows have what are the characteristics:
(1) Good sealing performance: The aluminum alloy itself is easy to be extruded, the cross-section dimension of the profile is accurate, and the processing precision is high. Optional sealing materials with good water resistance, elasticity and durability, such as rubber bead and silicone series sealant. In terms of profiles, various sealing strip fixing grooves have been completed along with the section in the extrusion process, creating favorable conditions for installing the sealing material.
(2) Light weight, high strength: The aluminum alloy material is mostly hollow core thin-wall combined section, convenient to use, light weight, and the section has high bending strength, and the finished door and window is durable and the deformation is small.
(3) Strong corrosion resistance: The aluminum oxide layer does not fade, does not fall off, does not need to be painted, is easy to maintain, and does not require maintenance.
(4) Beautiful appearance: After the surface of the aluminum alloy is electrochemically treated by the anode, it can display ancient lead copper, golden, silver and white colors, which can be arbitrarily selected and oxidized and polished. The sash frame is large and can be set with a large area of ​​glass, which makes the indoor light bright and bright, enhances the contrast between the indoor and outdoor façades, and makes the living room more rich.

Innovative goods, as well as plastic steel doors. It is lined with steel, and the outer skin is inlaid with plastic. The appearance is quite hard and lacquered. It can be made into double-layer doors with door frames, each set is about 500~800 yuan, and can also be customized according to the size specifications of the door. The plastic steel door has the characteristics of heat preservation, heat insulation, noise reduction, sound absorption, flame retardant, etc. It is economical and practical, and has a beautiful appearance.
How to choose a wooden door:
The most popular is the integrated wood craft wooden door. It is an international advanced wood processing technology that uses high-quality wood and is re-combined after being divided. It destroys the original cellular structure of the wood and forms a new structure, making it a new type of wood that is not easy to warp, deform and crack, to adapt to the temperature difference. With changes in humidity. Such wood is especially popular in some developed countries such as the United States and Japan.
