Some basic information about aluminum doors

Aluminum alloy door is the surface of the treated aluminum alloy profile, through the cutting, drilling, milling, tapping, production and other processing technology made of the door frame components, and then the use of connecting parts, sealing materials and open and close hardware Accessories combined assembly of a door. So, how to maintain the aluminum alloy door? Let's take a look!

What is the aluminum alloy door material
The door made of aluminum alloy extruded profiles for the frame, elevator and fan material is called aluminum alloy door, referred to as aluminum door. Including aluminum alloy as a force rod (bear and transfer the weight and load of the rod) base material and wood, plastic composite doors, referred to as aluminum wood composite doors, aluminum-plastic composite doors.

Aluminum alloy door classification
1, according to the door opening method: push-pull aluminum alloy door, flat aluminum alloy door, folding aluminum alloy door.
2, according to the type of door frame: general single outer frame aluminum door, single bread wall aluminum door, full frame wall sealing aluminum door.
3, according to the width of aluminum: 46 series, 50 series, 65 series, 70 series, 80 series, 85 series, 90 series, 93 series, 99 series and other aluminum alloy doors.

Advantages of aluminum doors
1, excellent decorative effect
Aluminum alloy doors can be made into a variety of colors and shapes, and the surface gloss, frame glass proportion is small, aluminum alloy doors can be made into large size division, very modern and beautiful, can add luster to the building.
2, good performance
Aluminum alloy door adopts thermal profile and insulating glass, has good energy saving effect and no frost, no dew, can meet the needs of any high-grade and high house building, is recognized at home and abroad, high-grade door products.
3, good processing performance
Aluminum profiles can be processed into large sizes and complex cross-section shapes, and the dimensional accuracy is high, the processing process of aluminum alloy doors is relatively simple, easy to realize modernization.
4, strong corrosion resistance
Aluminum oxide does not fade, does not fall off, does not need to paint, easy maintenance, no maintenance.
5, durable
After good surface treatment, aluminum profiles have good resistance to atmospheric corrosion, not afraid of moisture, not afraid of sunlight, high temperature deformation, low temperature non-embrittlement, no combustion, no aging, lightning protection, durable stability, suitable for various climate environments.
6. Light weight
The density of aluminum profiles is 1/3 of that of steel, higher than the strength, aluminum profiles per square meter of window are about 5KG, steel is 10-20KG, and plastic window frames weigh more than 10KG.
7, conducive to environmental protection
The waste aluminum material is easy to recycle, the reuse rate is high, and there is no environmental pollution problem in the process of processing.

Disadvantages of aluminum doors
1, the biggest disadvantage of the aluminum alloy door is its sealing, the poor sealing of the aluminum alloy door, if the plastic on the aluminum alloy door is used for a long time, it will fall off, which will lead to poor waterproof performance on rainy days, and after a long time, the aluminum alloy door will be oxidized, so that the entire appearance will be seriously affected.
2, and the thermal conductivity of aluminum alloy is very high, heat preservation, heat insulation performance is relatively poor.
3, although there are more aluminum alloy doors on the market, but the aluminum used are high-energy products, aluminum ingots are through the electrolytic aluminum process, each production of a ton of aluminum ingots consumes 1200 tons of electricity, so the cost of aluminum alloy doors is relatively high, so the price on the market is relatively high.

Aluminum alloy door optional
1. Thickness
Aluminum sliding doors have 70 series and 90 series, and 70 series can be used for aluminum sliding doors inside the house. The number of series indicates the number of millimeters of the thickness of the frame structure. Aluminum alloy sliding window has 55 series, 60 series, 70 series, 90 series four kinds.
2. Strength
The tensile strength should be 157 newtons per square millimeter and the yield strength should be 108 newtons per square millimeter. When purchasing, you can moderately bend the profile by hand, and it should be able to return to its original state after letting go.
3. Chroma
The color of the same aluminum alloy profile should be consistent, if the color difference is obvious, it is not suitable to buy.
4. Flatness
Check the surface of the aluminum alloy profile, there should be no depression or bulge.
5. Gloss
Aluminum alloy doors and Windows to avoid the selection of the surface with open bubbles (white spots) and ash (black spots), as well as cracks, burrs, peeling and other obvious defects of the profile.
6. Oxidation degree
Oxide film thickness should reach 10 microns. When purchasing, you can lightly scratch the surface of the profile to see whether the oxide film on the surface can be wiped off.

Aluminum alloy door maintenance
1, usually open and close the door action should be light, push and pull to be natural, do not pull hard push.
2, regularly collect ash, can not use toilet detergent, dirty powder and other strong acid and alkali detergent, usually use water, soapy water can be.
3, remember to clean the water in the trough in time, keep the door trough dry.
4, do not often use wet hands to grasp the handle to open the door, otherwise it will change color over time.
