One, what is the general thickness of aluminum alloy doors and windows?
The standard thickness for national standard aluminum alloy is greater than 1.2mm, while the thickness of aluminum alloy door and window profiles typically used in residential construction is generally around 1.4mm. However, in some projects without specific requirements, non-national standard aluminum alloy profiles with a thickness of 1.0mm are used to manufacture doors and windows, and their actual thickness ranges from 0.88mm to 0.98mm.
Two, are aluminum alloy doors and windows better when thicker?
The material used for aluminum alloy doors and windows is not necessarily thicker, and the specific material thickness depends on mechanical principles and the usage environment of the door and window. These require precise calculation by the R&D department. Using too little material creates a safety hazard; using too much material results in unnecessary waste and increased costs.
Three. How to distinguish the quality of aluminum alloy doors and windows
1、Inspect the material.
The main components of aluminum alloy doors and windows include aluminum profiles, glass, and hardware. The wall thickness of the aluminum profiles used in aluminum alloy doors and windows should not be less than 1.4mm, and the oxide film thickness should reach 10 micrometers. Tempered glass is significantly safer than ordinary glass. Aluminum hardware (such as latches, hinges, and handles) is also a good choice.
2、Regarding processing
High-quality aluminum alloy windows, with precise machining, smooth cutting, and consistent angles, will not exhibit significant gaps during assembly, offering good sealing performance and smooth operation. Poor-quality aluminum alloy windows may exhibit sealing issues, leading to air and water leakage, and in the event of strong winds and external forces, the glass may crack and detach.
3、Inspect the appearance
The surface of high-quality aluminum alloy doors and windows should not have obvious scratches, abrasions, dents, or other defects. The adjacent surfaces of aluminum alloy doors and windows should not have noticeable color differences. The surface of doors and windows should not have aluminum flakes, burrs, oil stains, or other dirt. The assembly connection should not have any extruded adhesive.
4、Assess performance
① Strength: This refers to the ability to withstand high pressure, which is relevant to the selection of aluminum alloy window profile materials.
② Air tightness: This refers to the sealing performance of the window structure, including whether the inner frame and outer frame of the window are tightly sealed.
③Waterproofness: Primarily, whether the aluminum alloy windows exhibit water accumulation or leakage issues.
④Sound Insulation: Dependent on the sound insulation properties of the hollow glass, the airtightness and closure capabilities of the air-tight strip structure, and the durability of the door and window accessories.
