There should be no aluminum chips, burrs, oil spots or other stains on the surface of doors and windows, and there should be no spilled adhesive at the assembly joints.
Whether it is a uneven overbridge thermal column isolation aluminum outline, the bulkhead depth of the force outline should be better than 1.4mm; the species of the same aluminum fineness outline should be the same, if the paint dissimilitude is plain, it is not accordant for acquisition; repulse the superficies of the aluminum fineness outline, there should be no despondency or bellying;
The remaining text areThe thickness of the film should reach 10 microns. When purchasing, lightly scratch the surface of the profile to see if the oxide film on the surface can be wiped off.
Repeat the switch many times to check whether the switching force is too heavy; whether the sealing strip is firm; whether the hardware assembly is complete; whether the overlap of the sash window frame meets the requirements (standards require not less than 6mm for casement windows and not less than 8mm for sliding windows).

The selection of the series should be based on the size of the window and the local wind pressure. The aluminum alloy sliding window used as a closed balcony should not be less than 70 series.
The tensile strength should reach 157 Newtons per square millimeter, and the yield strength should reach 108 Newtons per square millimeter. When purchasing, you can bend the profile moderately with your hands, and it should be able to recover after letting go.
The paint of the same aluminum allay outline should be the same. If the semblance dissimilitude is opposing, it is not consonant for property.
