Aluminum alloy doors and aluminum glass window refer to doors and aluminum glass window made of aluminum alloy extruded profiles as frames, stiles and fans, called aluminum alloy doors and aluminum glass window, or aluminum doors and aluminum glass window for short. Aluminum alloy doors and aluminum glass window include doors and aluminum glass window that use aluminum alloys as the force-bearing rods (rods that bear and transmit self-weight and load) and wood and plastic composite doors and aluminum glass window, referred to as aluminum-wood composite doors and aluminum glass window, aluminum-plastic composite doors and aluminium sliding window price.
The quality of aluminum alloy doors and aluminium sliding window price can be roughly judged from the selection of raw materials (aluminum profiles), aluminum surface treatment and internal processing quality, and the price of aluminum alloy doors and aluminium sliding window price.
⒈According to the material and function of doors and aluminium sliding window price, it can be roughly divided into the following categories: wooden doors and aluminium sliding window price, steel doors and Aluminum Window in china, revolving door anti-theft doors, automatic doors, plastic doors and Aluminum Window in china, revolving doors, iron flower doors and Aluminum Window in china, plastic steel doors and Aluminum Window in china, stainless steel doors and Aluminum Window in china, aluminum alloy doors and Aluminum Window in china, glass fiber reinforced plastic doors and Aluminum Window factory.
With the continuous improvement of people's living standards, the types and grades of doors and Aluminum Window factory and their derivatives continue to increase, such as heat-insulating aluminum alloy doors and Aluminum Window factory, wood-aluminum composite doors and Aluminum Window factory, aluminum-wood composite doors and Aluminum Window factory, solid wood doors and windows, solar energy houses, glass curtain walls, wooden curtain walls, etc. Wait.
⒉ According to the way of opening, it can be divided into: flat open, opposite, push-pull, folding, hanging, eversion and so on.
Take a look at the materials. The aluminum profiles, thickness, strength and oxide film used for high-quality aluminum alloy doors and windows should comply with relevant national standards. The wall thickness should be above 2.0 mm, the tensile strength should reach 157 Newtons per square millimeter, the yield strength should reach 108 Newtons per square millimeter, and the oxide film thickness should reach 10 microns. If the above standards are not met, the aluminum alloy doors and windows are of inferior quality and cannot be used.
Second, look at processing. High-quality aluminum alloy doors and windows, fine processing, exquisite installation, good sealing performance, and easy opening and closing. Inferior aluminum alloy doors and windows, blindly select the series and specifications of aluminum profiles, shoddy processing, use saw cutting instead of milling, do not install as required, poor sealing performance, inconvenient switching, not only air leakage and rain and glass bursting phenomenon, but also encounter Under strong wind and external force, it is easy to scrape or knock down the sliding part or the glass, causing damage to people.
Three look at the price. In general, the price of high-quality aluminum alloy doors and windows is about 30% higher than that of inferior aluminum alloy doors and windows due to the high production cost. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm, the tensile strength and yield strength are much lower than the relevant national standards, and it is very unsafe to use. In addition, there are many self-employed people who process aluminum alloy doors and windows, and they do not understand the structural characteristics and performance of aluminum alloy doors and windows. In order to reduce costs and cut corners, use shoddy products, and the hidden dangers of products are relatively large, so it is generally not suitable to use. It is best to choose products from regular aluminum alloy doors and windows manufacturers. Here is a special point: the national standard profile thickness is 1.4mm. If the supplier chooses a material with a wall thickness of 1.2mm or 1.0mm or even thinner, it is a product that does not meet the standard. Please pay attention when purchasing .
