What are the aspects of aluminum alloy doors and windows to roughly judge the quality of processing

Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles and fans, called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminum alloy doors and windows include wood and plastic composite doors and windows that use aluminum alloy as the base material of the force-bearing member (the rod that bears and transfers its own weight and load), referred to as aluminum-wood composite doors and windows, and aluminum-plastic composite doors and windows. The quality of aluminum alloy doors and windows 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 windows. ; Play a reconciliation between the two separate spaces.　　 The role of guidance and transition; it is the link that connects the space.　　Material partition door material can be metal, glass, composite board, fireproof board, gypsum board, flame retardant plywood, plywood, etc.　　The outer frame of the partition door can be all made of 6063 national standard aluminum extrusion profiles. The material, oxide film thickness, and surface treatment quality all meet the GB/T5237-2000 standard; it can also be made in a frameless way, directly connected with a toughened glass door hinge or fixed part. The standard gauge of the sliding door is 39.7mm. The upper rail has two styles, namely the standard upper rail and the curved upper rail. There are also two styles of the lower rail, namely the standard lower rail and the train rail; It solves the shortcomings of the original carbon steel hidden frame door that is easy to rust, vibrates, and is unstable and unsafe. At the same time, it overcomes the hidden danger of easy damage to the lower wheel caused by the deviation of the center of gravity of the sliding door. The unique design makes the sliding wheel universal with other sliding doors. , And make its life longer.　　Divided by regional characteristics The profile and glass styles of aluminum doors are divided into north and south. The north is characterized by thick aluminum and stable style. The most representative one is the grid style, and the most distinctive one is Tanger. The South is characterized by diverse aluminum shapes and flexible styles. The most representative one is the flower glass style. The more distinctive styles include grate, ice sculpture, basal sculpture, crystal shell and so on.
