How to choose the right aluminum alloy doors and windows

How to choose aluminum alloy doors and windows.

Features of aluminum alloy doors and windows Compared with steel and wood doors and windows, aluminum alloy doors and windows have the following advantages:

1) Light weight and high strength. The density is only 1 3 of steel.

2) Good sealing performance. The airtight performance directly affects the use function of doors and windows and the consumption of energy. The airtightness performance includes four aspects: air tightness, water tightness, heat insulation and sound insulation.

3) Good durability, easy to use and maintain. Aluminum alloy doors and windows are not corroded, faded, not falling off, almost no maintenance, and the service life of spare parts is extremely long.

4) Elegant decorative effect. The surface of aluminum alloy doors and windows have artificial oxide film and coloring to form a composite film layer, this composite film is not only corrosion-resistant, wear-resistant, has a certain fire-resistant, and the gloss is extremely high. Due to its light weight, precise and accurate processing and assembly, aluminum alloy doors and windows open and close lightly and flexibly, without noise.

Look at the materials: high-quality aluminum alloy doors and windows used in aluminum profiles, thickness, strength and oxide film, etc., should meet the relevant national standards, wall thickness should be more than millimeters, tensile strength of 157 Newtons per square meter of millimeters, yield strength of 108 Newtons per square millimeter, oxide film thickness should reach 10 microns. If it does not meet the above standards, it is inferior aluminum alloy doors and windows and cannot be used.

Look at the processing: high-quality aluminum alloy doors and windows, fine processing, exquisite installation, good sealing performance, free switching. Inferior aluminum alloy doors and windows, blind selection of aluminum profile series and specifications, rough processing, sawing instead of milling, not according to the requirements of installation, poor sealing performance, switch is not free, not only leakage and rain leakage and glass bursting, but also encounter strong wind and external force, easy to push and pull part or glass scrape or bump down, destroy and hurt people.

Look**: In general, high-quality aluminum alloy doors and windows are about 30% higher than inferior aluminum alloy doors and windows due to high production costs. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only millimeters have tensile strength and yield strength that are much lower than those stipulated in the relevant national standards, and are very unsafe to use.

Doors and windows are an indispensable part of the living room, which is related to the functional needs of lighting, ventilation, sealing, heat insulation, sound insulation, etc., as well as the needs of architectural decoration such as lines and color, and also represents the aesthetics and pursuit of the owner. Aluminum alloy doors and windows stand out among many door and window materials because of their good decorative effect and excellent performance, and have become a necessity widely used in modern homes.

Now Palid doors and windows will tell you about the four advantages of aluminum alloy doors and windows:

First, its own weight is light and high strength.

Aluminum alloy materials mostly use hollow thin-walled composite sections, light weight and density is only one-third of steel, its cross-section has high bending strength, and the doors and windows made are very durable and not easy to deform.

Second, the sealing performance is good.

Good sealing directly affects the use function of doors and windows and the consumption of energy. Generally, sealing refers to four aspects: air tightness, water tightness, heat insulation and sound insulation.

3. Beautiful shape and enhance the decorative effect.

After the surface of the aluminum alloy is treated, it can present a variety of different colors, which can be arbitrarily selected, and it is smooth and shiny after oxidation. The frame of the window sash can be made larger, and a larger area of glass can be inlaid to make the interior light abundant and make the home more layered.

Fourth, good performance, durable.

Long service life, aluminum alloy doors and windows have strong corrosion resistance, and the oxide layer is not easy to fade, does not fall off, does not need to be painted, is easy to maintain, and the door and window control system has a long service life.

As a modern, high-end building material, aluminum alloy doors and windows have been increasingly used in the decoration of family homes. How to choose the right aluminum alloy doors and windows? Here are some suggestions.

1.Look at the quality: the quality of aluminum alloy doors and windows is usually determined by the quality, model and surface coating of aluminum. Good aluminum alloy door and window materials should have the characteristics of high-specification aluminum materials, uniform surface color, super corrosion resistance, perfect surface treatment and spraying.

2.Look at the structure: the frame structure of aluminum alloy doors and windows should have a reasonable design, and the smooth and closed sliding end can greatly reduce the noise caused by air flow, which can meet the needs of different users, such as self-service windows, pop-up windows, hanging windows, etc.

3.Look at safety: safety is the core issue of choosing aluminum alloy doors and windows. From the perspective of the safety performance of doors and windows, aluminum alloy doors and windows should have high strength, high wind pressure resistance and water tightness, good heat resistance, and good anti-theft performance.

4.Look at the appearance: The design can directly affect the user's feelings. The pattern and color of aluminum alloy doors and windows should match the home decoration style. In terms of color and styling, consumers can choose according to their own personality and aesthetic needs.

5.Look at the service: a good manufacturer will continue to provide technical support and service guarantee in the process of pre-sale, sale and after-sale. The service quality of aluminum alloy door and window manufacturers can be investigated from the service commitment of the product, logistics distribution, after-sales maintenance and other aspects.

In short, aluminum alloy doors and windows are an indispensable one of our many home decoration materials. When choosing aluminum alloy doors and windows, we should consider all aspects such as material quality, construction geometry, safety, decoration and after-sales service. The final selection of aluminum alloy doors and windows should meet our own aesthetic needs and practical needs.

One look at the materials, two look at the processing, three look at the first, four look at the performance, like the high price ratio of the mu section I know that there are Nanus brand aluminum alloy doors and windows, in terms of quality, price is relatively better than other big brands.

There are mainly the following steps:

Thickness. There are two kinds of aluminum alloy sliding doors: 70 series and 90 series, and 70 series can be used for aluminum alloy sliding doors inside the residence. The number of series represents the number of millimeters of the thickness of the door frame construction size.

There are four types of aluminum alloy sliding windows: 55 series, 60 series, 70 series and 90 series. The selection of the series should be based on the size of the window opening and the local wind pressure value. Aluminum alloy sliding windows used as enclosed balconies should not be less than 70 series.

Strength. The tensile strength should be 157 Newtons per square meter and the yield strength should be 108 Newtons per square millimeter. When purchasing, you can use your hands to bend the profile moderately, and you should be able to restore it after letting go.

Chroma. The color of the same aluminum alloy profile should be consistent, if the color difference is obvious, it is not suitable to buy.

Flatness. Check the surface of the aluminum alloy profile, there should be no depression or bulge.

Glossiness. Aluminum alloy doors and windows avoid buying profiles with open bubbles (white spots) and ash slag (black spots) on the surface, as well as obvious defects such as cracks, burrs, and peeling.

Degree of oxidation. The thickness of the oxide film should reach 10 microns. When purchasing, you can scratch the surface of the profile to see if the oxide film on the surface can be wiped off.

1. Generally speaking, the doors and windows produced by regular manufacturers, the product name, product model or mark, the name or trademark of the manufacturer, the date or number of the manufacture and other information will be marked in the obvious position of the doors and windows, and we only need to pay a little attention to it.

2. For aluminum alloy doors and windows, of course, the country also has some corresponding standards. For example, the wall thickness of the aluminum profile of aluminum alloy doors and windows should reach more than 10 microns, and the thickness of the oxide film should not be less than 10 microns, which are closely related to the water tightness and wind resistance of doors and windows.

3. The appearance is not only good-looking, but the surface texture of aluminum alloy doors and windows will affect the overall decorative effect of the wall in the later stage. High-quality aluminum alloy doors and windows, the surface should be no depression or bulge, the paint treatment should be corrosion-resistant, wear-resistant and high-gloss, and the coloring surface of adjacent components should not have obvious color difference. Be sure to avoid buying profiles with obvious defects such as cracks, burrs, and peeling on the surface.

4. When choosing doors and windows, you can't help but look at the glass. We should pay attention to whether the installation of the glass is flat and firm, and there is no loosening. The outer surface of the double-layer insulating glass should be clean, and there should be no dust and water vapor in the interlayer, which is directly related to the sound insulation effect of doors and windows, as well as dustproof and waterproof performance.

5. Many people will unconsciously ignore the importance of hardware when buying doors and windows. For doors and windows, which are frequently used daily household facilities, the quality of hardware largely determines the experience and life of the product. When purchasing, we should pay special attention to its quality in addition to its appearance.

6. When choosing aluminum alloy doors and windows, in addition to considering their own quality and quality, they should also consider the actual situation of the house. For example, if you want to use it more conveniently, the casement window with an outward opening method is relatively more in line with the needs. In addition, it is necessary to consider whether it comes with a screen window, if not, but there is a demand, it is necessary to consider whether the optional screen window, window grille, and protective net match the aluminum alloy doors and windows.

7. Everyone should know that the tightness of doors and windows is a must. Therefore, when purchasing, it is necessary to pay great attention to the smooth contact between the sealing strip and the glass and the glass notch, and there can be no curling and de-groove problems. For doors and windows in a semi-closed state, there should be no obvious gap between the sash and the frame, and the sealing strip on the sealing surface should be in a compressed state.

The overall airtightness is mainly reflected in whether the inner sash and outer frame structure of the doors and windows are tight, and whether the aluminum alloy outdoor windows are tight and impermeable.

8. Everyone knows the truth that you get what you pay for, and you can't be greedy for cheap when buying doors and windows. Therefore, don't choose those products that are obviously low, or even lower than the average market price, because of the psychology of "taking advantage". Because you are very likely to encounter shoddy and inferior goods that cut corners.

Doors and windows are one of the important parts of residential buildings, not only to pay attention to the correct installation skills, but also to buy the best doors and windows to ensure that the doors and windows have good performance and long-term service life. Among all kinds of doors and windows, aluminum alloy doors and windows are used a lot, so what is the method of choosing aluminum alloy doors and windows? Let's take a look at the buyer of aluminum alloy doors and windows!

Aluminum alloy doors and windows purchase method1. Materials. The selection of materials will greatly affect the performance of its use of the car. Generally speaking, the thickness, strength and oxide film of high-quality aluminum profiles used for aluminum alloy doors and windows basically meet national standards, such as:

The wall thickness of the aluminum profile of the aluminum window should not be less than. Moreover, most of the high-quality aluminum alloy doors and windows are made of tempered glass and stainless steel hardware accessories, and the pulley is made of POM material, which can ensure that the aluminum alloy doors and windows have high strength and wear resistance, and will not be broken when used.

2. Processing. To see its production process, generally speaking, high-quality products, the production equipment it uses is more advanced, the technology is more advanced, so as to ensure that its tangent is smooth, the angle is consistent, and there will be no obvious gaps in splicing. At the same time, it can ensure that aluminum alloy doors and windows have good sealing performance, flexible and convenient operation.

When the processing of aluminum doors and windows is unqualified, not only does it leak wind and rain, but also under the action of strong wind and external force, the glass will fall off and other phenomena, so that the owner suffers property losses and even hurts people.
