How to judge whether it is a broken bridge aluminum window from the appearance?

1. The color is only broken bridge aluminum profile.

The batch is white, and the other materials are the metallic color of aluminum alloy, the manufacturer claims that the black electrostatic spraying part on the outside of the profile, and the white is the broken bridge aluminum after scraping off the electrostatic spray coating with a hard object, which is different from other profiles.

2. Look at the surface quality of the profile, the quality of the broken bridge aluminum profile can be observed from its surface, the surface of the good broken bridge aluminum profile is glossy and textured, and the surface spraying color treatment will also be natural, and it will feel smooth to look at. Broken bridge aluminum doors and windows.

The poor quality is mainly manifested in the fact that the surface is rough and dull, and after a period of use, there will be discoloration or fading, and the color is not full.

3. Look at the thermal insulation strip, the inferior broken bridge aluminum is inferior PVC thermal insulation strip with short service life, which is not strong enough and has the thermal expansion coefficient of aluminum alloy.

The difference is large, it is easy to age, and the insulation strip is deformed and falls off after long-term use, which will also affect the sealing performance of doors and windows.

4. Look at the hardware, use broken bridge aluminum, hardware is also very important, the right hardware can be matched with broken bridge aluminum to make your balcony more perfect, poor quality hardware, add insulating glass to the broken bridge aluminum fan.

The weight will fall after a period of time using the sash.

True and false broken bridge aluminum doors and windows from the appearance characteristics.

The biggest difference between broken bridge aluminum doors and windows and non-broken bridge aluminum doors and windows is that broken bridge aluminum doors and windows have heat insulation strips, while non-broken bridge aluminum doors and windows are integrated. The thermal insulation strip of the broken bridge aluminum doors and windows should be made of PA66 nylon thermal insulation strip, which is consistent with the linear expansion coefficient of aluminum alloy, durable and not easy to age. Of course, this is the easiest way to distinguish between them, which can be distinguished by the naked eye.

True and false broken bridge aluminum doors and windows from the color characteristics.

Broken bridge aluminum doors and windows also have an obvious advantage from non-broken bridge aluminum doors and windows, that is, they can be made of two-color, and non-broken bridge doors and windows need to be sprayed for two-color, which is unstable. The two-color of broken bridge aluminum doors and windows is stable, because it is synthesized by two aluminum alloy profiles + heat insulation strips.

It depends on the indoor and outdoor parts, whether the window frame is flush when opening and closing the window, if the outdoor part is flush, it is the outdoor flat frame, and vice versa; It is harder, safer, and less prone to corrosion.

It can be distinguished by the shape of the broken bridge aluminum doors and windows. The protection effect of such doors and windows is better, and it can play a rainproof effect, a moisture-proof effect, and a sound isolation effect, and the sound insulation effect is better.

It can be judged according to the structure, such a structure is safer, denser and more strong.

The worst of broken bridge aluminum doors and windows is mainly distinguished from the aspects of cavity design, whether the frame fan is glued, the sealing of the joint with the glass, and the insulating glass;

Cavity design: high-precision structure nylon heat insulation strip, heat insulation strip and rubber strip contact, to ensure the overall strength and accuracy of doors and windows, temperature changes, rubber strip will not be deformed, increase waterproof, dustproof effect;

Whether the frame fan is glued: there is a sealing strip outside the fan, and the corner of the frame fan has a German two-component glue injection type corner assembly process, which ensures that the opening is more flexible, will not be bumped, and the corner will not fall off after long-term use, so as to ensure the lifespan;

Insulating glass: use sealant strips on both sides of the glass, instead of using sealant, to ensure that the glass is not directly in contact with the profile, the force is more uniform, and the glass will not burst due to climate and wind pressure changes, and the most important thing is that the glass and the profile are in closer contact and the waterproof effect is better;

Insulating glass: the thickness is more than 5mm, the insulating layer of glass is not less than 12mm, and the glass surface has no water ripples and does not turn green, which is safer and protects the family; The sound insulation and thermal insulation effect are better, more transparent, and the lighting is better.

How to choose broken bridge aluminum doors and windows, how to distinguish the good and bad of broken bridge aluminum doors and windows.

Identifying broken bridge aluminum needs to be judged from its characteristics and performance, broken bridge aluminum is to disconnect the aluminum alloy from the middle, it uses hard plastic to connect the broken aluminum alloy as a whole, and the wall thickness of the broken bridge aluminum is.

The real broken bridge aluminum is made of PA66 nylon strips, and the PVC is relatively smooth and shiny; Broken bridge aluminum doors and windows.

The number of sealing channels in the inside, outside and in the middle of the three layers of sealing performance is good, to see whether the isothermal layer of the door and window is in a straight line, the isothermal layer is in a straight line is conducive to the improvement of thermal insulation performance, so to choose two broken bridges at the same straight line of doors and windows.

Teach you how to distinguish between real and fake broken bridge aluminum, come in and find out, it's worth collecting.

You just need to find a big brand company to do it!

The hardness of broken bridge aluminum alloy is sufficient, and it is very lightweight, so it is a very good building material for doors and windows. However, because of the superior performance of broken bridge aluminum alloy windows, there is an endless stream of counterfeit and shoddy products on the market. So how to identify the broken bridge aluminum alloy window?

I'm going to teach you a few ways here.

Identification method of broken bridge aluminum alloy window.

1. Window surface: The window frame should be clean, smooth, smooth, free of scratches and bruises on the large surface, and the profile should not be welded and broken.

2. Hardware: The hardware should be complete, the position is correct, the installation is firm, the use is flexible, and the use can achieve their respective functions.

3. Glass sealing strip: The contact between the sealing strip and the glass and the glass notch should be smooth, and it should not be curled or degrooved.

4. Sealing quality: When the door and window are half-closed, there is no obvious gap between the fan and the frame, and the sealing strip on the sealing surface should be in a compressed state.

5. Glass: The glass should be flat and firmly installed, there should be no loosening, the single-layer glass should not be in direct contact with the profile, the inner and outer surfaces of the double-layer glass should be clean, there should be no dust and water vapor in the glass interlayer, and the partition should not be warped.

6. Beading: The bead with sealing strip must be fully attached to the glass, there should be no obvious gap between the bead and the profile, and the joint gap should be less than or equal to 1 mm. 7 Patches:

The splice material should be tightly connected with the window frame, and at the same time sealed with caulking paste, not shaking, the screw spacing should be less than or equal to 600 mm, and both ends of the lining reinforced steel should be fixed firmly with the hole.

8. Switch parts: casement, sliding or rotating windows should be closed tightly.

9. The frame should be connected with the wall: the window frame should be horizontal and vertical, the height should be consistent, the spacing of the fixing pieces should be less than or equal to 600 mm, the frame and the wall should be firmly connected, the gaps should be filled with elastic materials, and the surface joints should be sealed with paste without cracks.

10 Drainage holes: The location of the drainage holes should be correct and unobstructed.

The above is the identification method of broken bridge aluminum alloy windows, simple and practical, I hope that every friend who has read this article can pick a high-quality product when choosing a broken bridge aluminum alloy window.

Kiss! Hello, happy to answer your <>

The bad methods for identifying broken bridge aluminum windows are as follows: 1. You can see the appearance of broken bridge aluminum doors and windows, good broken bridge aluminum doors and windows have fine workmanship and good gloss, and bad broken bridge aluminum doors and windows are not full of color and uneven tangents. 2. Look at the broken bridge aluminum doors and windows are empty of the five-opening tung burning gold parts, the best broken bridge aluminum doors and windows hardware has no particles, which inlay is more uniform, and the poor quality of the five complete pieces is fine, and there are impurities.

1.Do not use too much force when opening and closing doors and windows, do not use too much damage to doors and windows, the action should be gentle, it is best to install anti-collision devices, if the switch is not smooth, you can check whether the track parts are deformed, or something is stuck, do not push and pull hard with brute force, otherwise it is easy to suffer from problems such as frame deformation. 2. It is very important to inspect and maintain the hardware of the broken bridge aluminum doors and windows, and the hardware of the broken bridge aluminum doors and windows should be overhauled every once in a while, and if there is a problem, it should be repaired or replaced with a new one in time.
