How to avoid the pit when choosing Bridge-cutoff aluminum alloy doors and windows?
01. Aluminum
the Broken Bridge aluminum specifications on the market are still very Miscellaneous. From the perspective of texture, good materials should be smooth to touch and glossy; And in terms of thickness, the national standard is greater than 1.4mm, and the high-rise layer above 20 should be thicker. For heat insulation strips, PA66 is standard. Do not choose if it does not reach this standard, because its melting point is 253 ℃, it is not easy to ignite and has higher safety.

02. Glass
if you want a good sound insulation effect, 5 12 5 (the thickness of the glass on both sides is 5mm, and the glass is hollow 12mm) is OK. However, if you want a better sound insulation effect, you can choose 5 15A 15 hollow tempered glass, so you can hardly hear the noise after closing the window. Because tempered glass is a safety glass formed by toughening furnace high temperature treatment of ordinary glass. It is not only tough, but also not harmful when broken accidentally. It is very safe with broken bridge materials.

03. Hardware
solid and safe bridge breaking aluminium windows, in addition to high-quality aluminum profiles, hardware is also crucial. I advise you not to buy cheap hardware. The life span of inferior hardware accessories is usually only 2-3 years. If you want to use it for more than 10 years, you still need to buy famous accessories of big brands, SUS304 material is essential. This material will be more tough, and will not easily deform for a long time expose to wind and rain, which is very safe. If you don't know how to choose, you can weigh the thickness and try the hand feeling. It is really good only if it is loose but not fast, silky and tight.
