How to correctly identify the advantages and disadvantages of cast aluminum doors

When you just bought a new house, do you want to install a high -end cast aluminum door?

The market is so large, there are so many samples of cast aluminum doors Large, how can I buy a real high -quality cast aluminum door?

The development of the market makes the aluminum door product product product It was sprung up after the rain. Most of these manufacturers are transformation and upgrading, and earnestly work hard to make new products, but there are also many companies and individuals who come to the cast aluminum door to \”benefit good pictures\”. Miscellaneous assembly, which is well -charged, built in rough branches, and uses low prices to lure customers. As a result, many fake and shoddy cast aluminum doors have appeared, which disrupts the market, confuses customers\’ attention, and greatly damages the legitimate rights and interests of legal manufacturers, merchants and users.

Now telling you how to identify the cast aluminum door Quality and disadvantages. Avoid fake and inferior products from buying fake and inferior products. First teach you three tricks to subscribe to high-quality cast aluminum doors:

The first trick: See

Look at the surface paint. Don\’t think that the paint is bright, often the painted paint that looks very beautiful is very eye -catching, butThis kind of paint is often temporary, and it will fade soon; the painted paint baked from high temperature in the oven looks heavy, beautiful but not gorgeous, and is very eye -catching. This kind of paint can keep it for more than 10 years without fading.

The surface details of the second door. See if each welding point and connection point of the product are flat and non -marks; whether the door surface is flawed; when the door is closed, is there a flat and unique gap on the door. No granular bubbles. High -quality doors generally cannot find any flaws, and inferior doors will look like there are many problems.

The material of the main components such as the cast aluminum panel, the door frame steel plate of the three -looking door. The advantages and disadvantages of cast aluminum plates are not a thick relationship, but depending on the structural ingredients of cast aluminum alloy. We can check whether the exposed aluminum plates have dark spots from the lock hole. If so, it means that there are more impurities, and it must not be cast by the standard alloy aluminum ingot or recycled aluminum waste and aluminum. It will be oxidized and corroded soon; from the inside of the door frame, you can check the material and thickness of the steel plate of the door frame. The national standard of anti -theft door standards stipulates that the thickness of the steel plate is 2mm. At present, the door frames and door fans on the market are hot -dip galvanized steel plates, cold -plated cold plating, cold plating Zinc steel plates, cold rolled plates, stainless steel plates, aluminum profiles, etc. The best materials are hot -dip galvanized steel plates. This steel plate not only has good hardness and strength, but also never rust. Cold -rolled plate itself will rust; the paint of stainless steel plate has poor adhesion; the hardness strength of aluminum profiles is insufficient, easy to deform, and poor corrosion resistance.

The main hardware accessories such as the four -view door and sealing strip. The main hardware accessories of the cast aluminum doors are united pages, locks, and seals. In addition to the customer\’s independent options, these three accessories are prepared by the manufacturers. Due to the thickness of the cast aluminum door itself, the advantages and disadvantages of the union directly affect the use function and service life of the door. At present, the best pages on the market are Zhejiang Dingli Industrial Co., Ltd. develop and manufacture and obtain a national patent. Swaying the h -pages \”. The single bearing capacity of this club is more than 800kg, and it has super stability, sealability and safety to ensure that the door will never hang down and safe. Followed by Taiwan, the \”three -dimensional adjustment of the closure pages\” (the rotation part is exposed), a single load of 150kg, but its sealing, stability and anti -theft performance are poor, and the door is easy to sag and move. The other is the \”Heaven and Earth Heaven\” (two groups of upper and lower). The point of stress is mainly under the below of the club. Due to the unevenness of the efforts, the use wear is inconsistent. ; Sealing strips play a vital role in sound insulation, insulation, and safety of the gate. At present, the best sealing strip is EPDM (Sanyuan E -Curetic) as the same material used on the car. This sealing strip is soft and delicate. Good elasticity,Without cracking, he has a long life. If it is relatively hard, rough, and poorly sealing strips, it is easy to deform and poor elasticity, which will crack, which will greatly affect its sealing and safety.

Second trick: touch

Strong> The smoothness and hardness of the paint on the facade. Touch the feeling of painting on the surface of the door more direct, whether it is smooth and smooth, and whether there are particles. We can also use fingernails to lightly test their smoothness and hardness. The paint hardness of good quality doors is standard, generally no less than 2h, and there is no problem with nails or other blunt wares.

The flatness of the surface junction of the two door. The door frame of the good door is no trace. It is very flat and smooth, without bumpy, and the door fan is also neat and flawless.

The screws on the side and the side of the lock. The screw should be the material of the stainless steel. It is best to have the inner hexagonal cap. Whether the combination of the hand and the door fan or the lock body is flat and whether the screw surface is smooth.

The flexibility and elasticity of the four -touch sealing strip. The flexibility and elasticity of the high -grade rubber triple -meter -By -C -fi -tank seal are very good. If the seal with poor flexibility and elasticity, the theater\’s insulation, sound insulation, windproof, and anti -theft are poor.

Third trick: Listen

The sound of opening the door and closing. The sound of \”Peng\” indicates that the gap between the door fan has problems with the sealing bar. >

The sound insulation performance of the second listening door. After the testing department, it was tested to determine that the aluminum door of Ouhua Zun dwelling was reduced by 35 decibels.

Three listening to the sound of light knocking on the door. It shows that the middle of this door is empty or the door panel is very thin and not posted on the door bone. The door is just beautiful and defeated. This door is always a thick and heavy sound, and there will be no empty and abnormal sounds. There is no sound When the door of good quality is closed, there is no gap, and the hands cannot be pushed, so there will be no sound when pushing. The gap is large or the seal is not sealed.
