As the raw material of doors and windows: aluminum profiles, play a very important role! For small white doors and windows, the market large and small aluminum alloy doors and windows brands and materials are dazzling and messy, so how to choose the right aluminum profile in the mixed aluminum market? What are the factors related to the quality of aluminum profiles?

1. Appearance

Check whether the appearance is natural in color and whether the touch surface is smooth and even. There is no abnormal sound on the percussion surface, and the products with good quality and sufficient materials are generally full of sound. Gently scratch the surface to see if the oxide film on the surface can be wiped off.

2. Wall thickness

According to the international standard for aluminum profiles, the minimum nominal wall thickness of aluminum profiles for doors and windows shall not be less than 1.2mm, and the normal wall thickness shall generally be 1.4mm or more. However, some businesses reduce costs in order to attract customers, reduce the single weight of aluminum profiles, make the wall thickness very thin, and the quality is not guaranteed, which has a great impact in the later period.

3. Insulation strips

Aluminum profiles are generally divided into four types: I, C, T, and cavity types. Type I is too narrow and the heat insulation performance is not good, but if it is thickened or a straight line is formed at the broken bridge, the heat insulation performance is improved. Type C: route extension, heat insulation performance improvement. Cavity type: cooperate with multi-cavity middle rubber strip to effectively control convection and radiation effects between frame fans. If you are worried that businesses even cut corners on heat insulation strips, you can suggest lighting the heat insulation strips with a lighter to see if there is any damage and pungent odor.
