Be sure to pay attention to these points when choosing broken bridge aluminum doors and windows:
1. Profile: There are two main data related to profiles - profile wall thickness and profile width. The national standard for profile wall thickness is 1.4mm, and some street stores only have 1.2 or 1.3mm. In order to avoid such substandard products from appearing in the window openings of your home, it is recommended that you measure the product in person when it is delivered to your home for installation to ensure that it is genuine. Real stuff.
2. Profile width, ranging from 50/70/90/108/120/135mm. The requirements for profile width are different for middle, high and low floors. There are few choices for 120 and 135 families. If it is too thick, there is no Necessary; 70/90/108 is a hot-selling product. The profile width is moderate, the stability and wind pressure resistance are moderate, and it basically meets the needs.
3. Heat insulation strips. The heat insulation strips are embedded inside the broken bridge profiles. Merchants in door and window stores will usually show you the semi-finished products of the broken bridge aluminum. You can ask about the brand and price of the heat insulation strips and make a comparison between several stores. This way I have a general idea.
4. Hardware. Price and appearance come second. Quality is your priority. It may not necessarily be the best and most expensive, but the quality must be decent.
