Material characteristics of aluminum alloy screen window
Aluminum alloy screen window material is durable, with the characteristics of anti-aging, non-deformation, anti-freezing and sun protection. The color of aluminum alloy frame can be powder spraying and electric spraying, and there are many colors to choose from.
The thickness of aluminum alloy screen window frames on the market varies, some are 0.7mm, and some are as high as1.0 mm. Of course, the thicker the frame, the more durable and sturdy it is!
Selection skills of aluminum alloy screen window materials
1, see materials.
The thickness, strength and oxide film of the aluminum profile used for a good aluminum alloy screen window should meet the relevant national standards. The wall thickness is 65438 0.2 mm, the tensile strength is 65438 057 Newton per square millimeter, the yield strength is 65438 008 Newton per square millimeter, and the oxide film thickness is 65438 00 micron. If you can't meet the above standards, it is inferior aluminum alloy screen window? , not available.
Step 2 mark
Regular or licensed production enterprises should indicate product identification in the prominent parts of their aluminum alloy products, including: the name or trademark of the production enterprise, product name, product model or logo, production date or number, etc. For example, Suzhou Guan Sheng Metal Products Co., Ltd. has eye-catching words and signs of "moistureproof", "handle with care" and "upward" on the packaging box of its products. This is in line with the regulations.
Step 3 look at processing
Good aluminum alloy screen window has fine processing, exquisite installation, good sealing performance and convenient opening and closing. Inferior aluminum alloy screen window, blindly choose aluminum profile series and specifications, shoddy processing, sawing instead of milling processing, not installed as required, poor sealing performance, uncomfortable switch. Through the introduction of Mr. Li, the person in charge of Guangzhou Nonferrous Metals Industry Expo 20 1 1, it is also known that inferior aluminum alloy screen windows are not only prone to air leakage, rain leakage and glass cracking, but also easy to scrape or knock off push-pull parts or glass when encountering strong winds and external forces, which will damage things and hurt people.
4. Surface quality
The surface quality of screen window is directly related to the decorative effect of the whole wall after installation. When checking the surface quality of screen window, we should pay attention to the following aspects:
A, the color surface of adjacent parts on the screen window can't have obvious color difference.
B, the decorative surface of the screen window can't have obvious damage. It means that the protective film on the surface of the screen window cannot be scratched.
C, assembly joint can't have overflow adhesive.
5, size deviation
It is advisable to minimize the size deviation of aluminum alloy screen window frame.
6. Aluminum alloy screen window assembly
The connection of aluminum alloy screen window assembly should be firm, and the connection part should be sealed and waterproof with corrosion-resistant filling material.
7. Look at the price
Under normal circumstances, the price of high-quality aluminum alloy screen window is about 30% higher than that of inferior aluminum alloy screen window because of its high production cost. The tensile strength and yield strength of some aluminum alloy screens made of aluminum profiles with a wall thickness of only 0.6-0.8 mm are far below the relevant national standards, so it is very unsafe to use.
Through the above small series, we learned about other characteristics of aluminum alloy screen window materials, and we also introduced how to choose aluminum alloy screen window materials. I believe that through the above content, everyone has a further understanding of you and the material of the screen window. Because there are many aluminum alloy screen window materials on the market, we don't know how to choose them when choosing. You can refer to the above when choosing. I hope the above content is helpful to you.
