How to choose the right aluminum alloy doors and windows
Doors and windows are an indispensable part of a house. When it comes to doors and windows, many people will choose aluminum alloy doors and windows. Aluminum alloy doors and windows have very good decorative effects and have performance characteristics such as wind pressure resistance, aesthetics, water tightness, sound insulation, and heat preservation. Therefore, aluminum alloy door and window profiles have become the key objects of home decoration. When choosing doors and windows, we should pay attention to its material, thickness, color, flatness, glossiness, and degree of oxidation.
According to the strength
Both the tensile strength (157 Newtons per square millimeter) and the yield strength (108 Newtons per square millimeter) should be met. When purchasing, you can bend the aluminum alloy profile moderately with your hands, and it should return to its original shape after letting go.
According to the chromaticity
The same aluminum alloy profile should have a constant hue. It is not appropriate to purchase if the color difference is noticeable.
According to the flatness
Look at the aluminum alloy profile’s surface; there shouldn’t be any bulges or depressions.
According to the glossiness
Aluminum alloy doors and windows should avoid purchasing aluminum alloy profiles with open air bubbles (white spots) and ash residue (black spots) on the surface, as well as obvious defects such as cracks, burrs, and peeling.
According to the oxidation degree
The oxide film thickness should reach 10 microns. When purchasing, you can lightly scratch the profile’s surface to check if the oxide deposit can be removed.
