1 Thickness:

In China, there are 70 series and 90 series aluminum alloy sliding doors.

The number of series indicates the number of millimeters of the thickness of the door frame.

Aluminum alloy sliding windows are available in 55 series, 60 series, 70 series,75 series, 80 series, 85 series and 90 series.

The selection of the series should be based on the size of the window opening and the local wind pressure.

2. Strength:

The tensile strength should be 157 Newtons per square meter and the yield strength should be 108 Newtons per square millimeter.

When purchasing, you can use your hand to bend the profile moderately, aluminum profile can be able to recover after loosening your hand.

3. Color:

The color of aluminum alloy profile should be consistent.

If the color difference is obvious, it is not good for purchasing.

4. Flatness:

Check the surface of aluminum alloy profiles, no dents or bulges.

5. Glossiness:

Avoid the appearance of air bubbles (white spots) and slag (black spots), as well as cracks, burrs, peeling and other obvious defects of Aluminum alloy doors and windows profiles

6. Surface:

In general, anodizing, powder coated, Electrophoresis coating, wood grain effect, and fluorocarbon can be used for aluminum door and window profiles, now some mechanical treatment can be done with the surface treatment, such as sandblasting, brushing, polishing and strip feeding thermal break or injection thermal break.

With the development of technology, more surface treatment will be applied for aluminum profiles for windows and doors.
