The emergence of aluminum alloy doors and Windows industry has also led to the development of aluminum alloy door and window equipment.
A lot of customers can't do it, don't know how to choose? Quality, price and after-sales are three points that customers care about, but consumers choose aluminum.
The following points should be paid attention to:
1. Strength: the tensile strength should reach a height of 157 Newton per square meter, and the yield strength should reach 108 newtons per square millimeter. When you choose, you can use your hands.
Bend the profile moderately, and should be able to recover the original shape after release.
2. Chromaticity: the color of the same aluminum alloy profile should be consistent, if the color difference is obvious, it is not suitable to buy.
3. Flatness: check the surface of aluminum alloy profiles, and should not be dented or bulging out.
4. Gloss: aluminum alloy doors and Windows avoid open air bubbles (white spots) and ash (black spots), as well as obvious defects such as cracks, burrs and peeling.
5. Oxidation degree: the oxide film thickness should reach 10 microns. When choose and buy, can be on the surface of the shape material lightly, see whether the oxide film of its surface can erase.
The installation of aluminum door and window equipment should also pay attention to the following points:
1. Doors and Windows must be firmly installed, and the number, location and connection method of embedded parts must conform to the design requirements, which shall be used to fix each reinforced section steel.
The fasteners shall not be less than 3, the spacing shall be no more than 300mm, and the end of the section steel shall be no more than 100mm; Reinforced bar, fasteners and hardware.
The surface of stainless steel should be treated with corrosion resistant coating.
2. When the doors and Windows are connected with the wall, the wood brick should be embalmed;
3. The expansion joint between the window frame and the opening should be filled with the closed hole foam plastic, the foamed polyphenyl ethyl and other elastic materials, and the surface shall be sealed.
Rubber seal. For the project with high insulation and sound insulation requirements, appropriate insulation and sound insulation materials should be used.
4. Doors and Windows are clean, without scratches, bruises, and no rust; The coating is smooth, flat and thick.
Uniform, no porosity; It is forbidden to install scaffolds or heavy objects on the door window frame, fan or tin, and do not pedal the window frame, window fan or window plate. Door and window
Oily and so on, should be washed with water-soluble detergent, avoid rough or corrosive chemical liquid scrubbing.
