1.aluminum
The aluminum used for good aluminum alloy doors and windows has a smooth and shiny surface, no aluminum chips, burrs, etc. Its strength, thickness (≥1.4mm), and oxide film (≥10 microns) must conform to national standards, and small door and window manufacturers are at In the mixed market structure, there are many “thin materials” shoddy, and consumers are advised to choose reliable and well-known brand products.
2.glass
Compared to ordinary glass, tempered glass is clearly a better choice. It has strong impact resistance and is not easy to be broken. Even if it is broken, it will be broken in the form of particles without sharp angles, which will greatly reduce the damage to the human body. At the same time, it has good thermal stability, and the tempered insulating glass has better sound insulation effect.
3.hardware
The quality of hinges, door handles, locks, pulleys and other hardware accessories is the key to ensuring the service life of aluminum alloy doors. Using stainless steel hardware, bright color, no rust, scratching, etc., the most important thing is to choose reliable brand hardware, big brand hardware and profiles will be engraved with brand LOGO.
4.crafts
Good aluminum alloy door and window products, fine processing, smooth tangent, accurate angle, no obvious gaps in the splicing process, good sealing performance, smooth switch.
5.auxiliary accessories
Sealing strips and tops are important accessories for ensuring aluminum doors, especially hollow doors. The sealing strip must have sufficient tensile strength, good elasticity, good temperature resistance and aging resistance, and the cross-sectional structure size should match the aluminum door profile. The tops need to have sealing performance, good waterproof performance, and dense dustproof.
