What are the standards for heavy-duty sliding door aluminum profiles? As an indispensable part of modern architecture, the standards of heavy-duty sliding door aluminum profiles directly determine the performance, safety and service life of the door. When purchasing heavy-duty sliding doors, it is crucial to understand and follow the relevant standards of aluminum profiles.
The thickness of aluminum profiles is one of the important indicators for judging their quality. National standards stipulate that the wall thickness of aluminum profiles for heavy-duty sliding doors should not be less than 1.4mm, while high-quality products usually reach 1.8mm to 2.5mm. This standard ensures the firmness and load-bearing capacity of the door body and is suitable for large-area spaces such as industrial plants, road tunnels, and airports.
The tensile strength and yield strength of aluminum profiles are key parameters for measuring the performance of aluminum profiles, which should reach 157 Newtons per square millimeter and 108 Newtons per square millimeter respectively. Such strength standards ensure that sliding doors are not easily deformed during long-term use and have high stability and durability.
In addition, the surface treatment of aluminum profiles is equally important. The thickness of the oxide film should reach more than 10 microns to enhance corrosion resistance and aesthetics. When purchasing, consumers can lightly scratch the surface of the profile to check whether the oxide film is easy to fall off, so as to judge its quality.
Through the above understanding, the standards of heavy-duty sliding door aluminum profiles cover thickness, strength, surface treatment and other aspects. These standards together constitute an important system for measuring the quality of aluminum profiles, providing a scientific basis for consumers to purchase high-quality, high-performance heavy-duty sliding doors. Therefore, during the purchase process, consumers should carefully check the product parameters to ensure that the selected aluminum profiles meet national standards and their own needs.
