How to choose custom aluminum single hung window
Second, look at processing. High-quality aluminum single hung window,custom aluminum windows and aluminum door , fine processing, careful installation, good sealing performance, and easy opening and closing. Inferior aluminum alloy doors and windows, blindly select aluminum profile series and specifications, use inferior product processing, sawing instead of milling, installation is not as required, poor sealing performance, uncomfortable opening and closing, not only air leakage, glass explosion, but also strong in wind and external forces During the operation, the sliding parts or the glass can be easily scratched or knocked, which can lead to property damage and injuries.Three look at the price. In general, high-quality aluminum alloy doors and windows are about 30% more expensive than inferior aluminum alloy doors and windows due to high production costs. The tensile strength and yield strength of some doors and windows made of aluminum alloys made of aluminum profiles with a wall thickness of only 0.6 to 0.8 mm are well below the relevant national standards, which is very unsafe to use. In addition, there are many self-employed people who process aluminum alloy doors and windows, and they do not understand the structural characteristics and performance of aluminum alloy doors and windows. In order to reduce costs and trade-offs, this product has major hidden dangers and is usually not suitable for use. It is best to choose products from regular aluminum alloy doors and windows manufacturers. Here is a special note: the national standard profile thickness is 1.4mm. If the supplier chooses 1.2mm or 1.0mm wall thickness or even thinner materials, they are all substandard products. Please pay attention when purchasing.
Four look at the material There are six main aspects for reference in material materials:
⒈Thickness: There are 70 series and 90 series for aluminum single hung window and windows. The 70 series is sufficient for aluminum alloy sliding doors inside the residence. The number of aluminum alloy series indicates the number of millimeters of the thickness of the door frame. Common aluminum sliding windows have four types: 55 series, 60 series, 70 series and 90 series. The selection should be based on the size of the window hole and the local wind pressure value. The aluminum alloy sliding window used as a closed balcony should not be less than 70 series.
⒉Strength: The tensile strength should reach 157 Newtons per square millimeter, and the yield strength should reach 108 Newtons per square millimeter. When purchasing, the profile can be bent moderately, and the shape should be restored after letting go.
⒊Chromaticity: The color of the same aluminum alloy profile should be the same. If the color difference is obvious, it is not suitable for purchase.
⒋Flatness: check the surface of the aluminum alloy profile, there should be no depression or bulging. ⒌Glossiness: Aluminum alloy doors and windows should avoid the selection of profiles with obvious defects such as open bubbles (white spots) and slag (black spots), cracks, burrs, peeling, etc. ⒍Oxidation degree: the thickness of the oxide film should reach 10 microns.When purchasing, lightly scratch the surface of the profile to see if the oxide film on the surface can be wiped off. Doors and windows are building units, decorative symbols of facade effect, and finally reflect the characteristics of the building. Although different buildings have different requirements for the design of doors and windows, and the wide variety of doors and windows is ever-changing, some rules can still be found.
⒈The door and custom aluminum windows facade division should conform to the aesthetic characteristics, and the following factors should be considered when designing the division
⑴The coordination of the division ratio. For a single glass plate, the aspect ratio should be as close as possible to the golden ratio. It is not suitable to be designed as a square and a narrow rectangle with an aspect ratio of 1:2 or more. The height of the beam is generally 1/4 to 1/5 of the frame height. Big or too small
⑵The facade division of doors and windows must have a certain pattern, but also reflect changes, and seek regularity in the changes; the division lines are dense and dense; the equidistant and equidistant divisions show rigorous, solemn and serious; unequal distance freedom The division shows rhythm, liveliness and movement;
⑶ At least the horizontal grid lines of the same room and the same wall doors and windows should be on the same horizontal line as much as possible, and the vertical lines should be aligned as much as possible;
⑷When designing the facade of doors and windows, the overall effect requirements of the building should be considered, such as the contrast between the virtual and the reality of the building, the effect of light and shadow, and the symmetry.
