The characteristics of aluminium alloy door and window are compared to steel wood door window, aluminium alloy door window has the following advantage:
(1): light weight and high intensity. The density is only l / 3 for the steel.
(2): tight performance. The sealing performance directly affects the use of Windows and doors and the consumption of energy. The sealing performance includes four aspects such as air tightness, water tightness, heat insulation and sound insulation.
(3): good durability and easy maintenance. Aluminum alloy doors and Windows do not rust, fade, do not fall off, almost no need to repair, spare parts use life extremely long.
(4): the adornment effect is elegant. Aluminum alloy door and window surface have artificial oxidation film and colouring to form compound film layer, this kind of compound film is not only resistant to corrosion, wear-resisting, have certain fire resistance, and the gloss is extremely high. Aluminium alloy door window because of self-heavy light, the processing assembly is precise, accurate, so open and close lightness and agile, no noise.
The type and specification of the aluminum alloy doors and Windows
(1): The product code of aluminum alloy doors and Windows: the contents of flat aluminum alloy window are also suitable for the sliding axle flat open window HPLC, fixed window GLC, upper hanging window SLC, lower hanging window XLC, middle suspension window CLC, vertical window LLC.
(2): size.
(3): the strength of aluminum alloy doors and Windows by wind pressure, air permeability (air) and rainwater infiltration (watertight) three performance indexes, can be divided into A (high performance Windows and doors), B (performance of doors and Windows), C (low performance Windows and doors) three categories.
aluminum alloy door and window product mark rule: the user chooses aluminium alloy door window, the first according to the room size chooses the proper door window. Size of the specification, according to the usage requirement, choose the right type of door and door. Next according to the use of door window (such as inside door, door) to determine the various performance requirement of door window, such as window and regulation door requirement have certain insulation, sound insulation, water tight, air tightness requirement. Finally the user chooses the color of the door window frame according to his preference and the collocation of other adornment place.
