[China Aluminum Industry Network] Broken-bridge color aluminum alloy doors and windows are more suitable for high-end windows, because of its characteristics: (1) The composition of broken aluminum alloy doors and windows is a combination of the environmental protection of wooden windows, iron windows and steel windows. The commonness of steel doors and windows insulation and energy saving is formed by the combination of two different sections through energy-saving and heat insulation strips. Insulation bar is also called nylon bar. Its main function is to play the role of disconnection in the heat transfer and prevent the rapid transfer of heat and cold or slow heat transfer. Its structure is more complicated than the ordinary aluminum doors and windows, and the cost is higher. The ordinary color aluminum does not have heat insulation strips, and no insulation or energy saving is only done on the surface. (2) The wall thickness of the profiles of the aluminum alloy doors and windows of broken bridges strictly follows the national standards. Wall thickness requirements must be above 1.4mm, because the thin wall thickness relates to the assembly technology and the solid security issues that make up the doors and windows. The common color aluminum doors and windows wall thickness requirements are not very strict, generally based on the market and processing window and field benefits, generally about 1.0mm. (3) Assembling technical requirements for color aluminum doors and windows and normal color aluminum doors and windows of bridges. Features: The color aluminum doors and windows of bridges are cut through a wall thickness of 1.4mm or more to a 45-degree angle, and a special plug-in at a corner of 3mm or more is adopted. Windows and doors assembled complete sets of equipment. Extrusion positioning, while the ordinary doors and windows are made of 1mm or so ordinary aluminum rivets connected together, its solid security is poor, but the cost is low. There is no problem for adults standing on the walk with the assembled color broken aluminum doors and windows. The assembly of equipment and the use of manual on-site assembly are technically very different. Special bridge aluminum profiles and ordinary aluminum profiles cannot be compared. (4) The color broken aluminum doors and windows of the broken bridge must be customized by the aluminum manufacturer's professional production cycle. The color processing of the surface is professional and technical, and the service life is longer. However, the ordinary color aluminum doors and windows are made of any ordinary aluminum. Material, without a special treatment to paint a color of their own, technical processing without aluminum manufacturers in place professional, coating effect and useful life will not be too good, fade too long will appear fade phenomenon, known as leather glands, Thus, it is determined that the color aluminum doors and windows of the broken bridge have a long production cycle, while the ordinary color aluminum doors and windows have a short production cycle. (5) The design of colored aluminum doors and windows of broken bridges is not the same as that of ordinary aluminum doors and windows. The design pattern of broken bridges is atmospheric. The lighting is transparent, and it is designed according to different spaces, while ordinary aluminum doors and windows can only be designed according to the conventional design. Broken window opening windows design is a large design, special broken bridge flat window hardware, and general aluminum is any kind of hardware can be used, beautiful and poor. (6) The broken window glass must be hollow glass 5mm + 9A + 5mm double-sided tempering, while the ordinary color aluminum are generally single-living glass, so the sound insulation effect of broken bridge is good.
