1. Aluminum.

First of all, it is necessary to see whether the aluminum used is a high-strength aluminum alloy, and whether the weight can reach a thickness of 3mm; And now many businesses on the market in order to reduce costs, the thickness is not up to standard. On the surface, there is no big difference, but over time, the problem will be exposed, such as loosening, deformation, there are great safety hazards!

2. Glass. See if the glass has special tempered glass that has passed the national compulsory 3C safety certification. In addition, it is also necessary to see whether the 3C certification mark is tempered into the glass, so as not to be confused by the printed or pasted 3C mark.

3. Rivets. Frameless balcony windows are mainly composed of glass and aluminum alloy, and the glass and aluminum alloy are connected by rivets. At present, many businesses on the market use hand-pulled aluminum rivets to connect, and its beauty must be needless to say, with a long time, it will loosen or fall off in the wind and sun. The correct one should be connected with solid steel rivets with air pressure to press, which is both beautiful and safe, but this requires the introduction of related equipment, which is something that many businesses are unwilling to invest.

4. Workmanship and accessories.

The workmanship of frameless balcony windows mainly depends on whether the gap between the profile and the accessories is compact, whether it is smooth when sliding, and whether the smoothness is related to the lubrication of the wheels and the wear resistance of the wheels. When the sash slides, there is loud noise, and whether it is good to push and pull.

5. Design, installation and after-sales.

Frameless balcony windows have a high gold content in the design, production and installation, like some high and low balconies, the manufacturer's technology is not up to standard, it is difficult to deal with it in place; More importantly, frameless balcony windows are products that need to be maintained, and the manufacturer's after-sales guarantee is particularly important.

Precautions. 1. Don't go to the small store at the entrance of the community to buy, this kind of store may be closed after a year and a half, and there is no after-sales guarantee.

2. In terms of price, it is necessary to compare the total price of auxiliary materials and labor costs, and do not just look at how much glass is 1 square meter.
