Only those aluminum profiles with broken bridges are white, and other materials are metallic colors of aluminum alloy. The manufacturer claims that it is the black electrostatic spraying part on the outside of the profile. Scraping off the electrostatic spraying layer with a hard object is broken bridge aluminum, which is different from other profiles.

2, look at the profile surface quality

The quality of broken bridge aluminum profile can be observed from its surface. The surface of a good broken bridge aluminum profile is shiny and textured, and the color treatment of the surface will be natural and it will look smooth. The poor quality of broken aluminum doors and windows is mainly manifested in: rough and dull surface. After a period of use, it will change color or fade, and the color is not full.

In the broken bridge aluminum window, the heat insulation strip is also a very important part. The deterioration of insulation strip directly affects the service life of broken aluminum, and a good insulation strip has good wind resistance, sand prevention, sound insulation and rain prevention effects. Generally speaking, PA66 nylon is needed for the insulation strip of broken bridge aluminum profile, because PA66 nylon insulation strip can bear a certain weight. Moreover, in terms of color, pure black is a better material, with no concave and convex points on the surface and no pungent smell. This kind of insulation strip will be better. PA66 nylon insulation strip is used for brand broken bridge aluminum insulation strip, which is consistent with the linear expansion coefficient of aluminum alloy, durable and not easy to age. Generally, the insulation strips of broken bridge aluminum have electronic codes, which is also an important method to distinguish the true and false brands of broken bridge aluminum.

4. Look at the hardware

Using broken bridge aluminum, hardware is also important. Appropriate hardware can be matched with broken bridge aluminum to make your balcony more perfect. Inferior hardware will fall with the window sash after being used for a period of time under the heavy pressure of broken aluminum fan and insulating glass.

Different series of broken aluminum windows have different wall thicknesses. Generally, the thickness of 60 series is 1.2mm- 1.8mm, and there are also 55 series profiles. There are also large windows that can use 70 or 75 profiles, depending on the individual needs of users.

Second, what are the skills to buy broken bridge aluminum?

Choosing broken aluminum doors and windows, its sealing is also very important. The sealing performance of inferior broken bridge aluminum doors and windows is very poor. After a long time, a lot of dust will accumulate on the window, which will hinder the opening and closing of the window and make it difficult to clean.

Secondly, the choice of doors and windows depends on whether the joints of the windows are defective. We must carefully check whether the windows are firmly connected, otherwise problems will appear one after another after a period of time.
