Why choose aluminum door


When choosing a door, first consider whether it will rust and deform.​​​​ Because the aluminum art gate adopts the production process of integral casting, it will not be deformed when used outdoors. At the same time, due to the nature of aluminum, it is not easy to rust. Therefore, when choosing a gate, it is recommended to choose an aluminum gate. Except for some accessories, the aluminum door is made of aluminum alloy. In production, high-end aluminum art gates will use engraving techniques to make the gates more three-dimensional. Coupled with a more atmospheric color, the aluminum art gate will be more high-end and atmospheric.


The main advantage of aluminum doors is more stable performance. Although the cost of decoration has increased, it can perfectly reflect the owner's taste and the owner's pursuit of beauty.

The difference between flush bolts and countersunk head bolts for aluminum doors



The head of the flat head screw is at right angles to the bolt connection part, which will be more convenient in our use process. The countersunk head bolt extends from the bolt head and the tapered road to the screw. The head of the screw and the product surface are flat and feel no difference.


Combination method

Because the joint of the flat head bolt is at a 90 degree angle, it can be used in conjunction with a flat washer and a spring washer according to the actual use. However, countersunk screws can only be used with conical washers.


How to use

Flat-head bolts can go deep into the counterbore or on the outside, while countersunk screws are generally only on the inside. Therefore, it can be seen at a glance which one is a flat head and which one is a countersunk head from the usage situation.


Flush bolts are used in engineering occasions such as construction sites. The countersunk head screws are mostly used after installation. There are two types of thick parts and thin parts. The so-called thick ones tighten up. The thickness of the solid part is greater than the thickness of the head of the countersunk screw. After the screw is tightened, if the thread of some screws does not enter the threaded hole, the screw can be tightened, and the thickness of the tightened part is less than the height of the head of the countersunk screw, then this kind of machine is common in the sheet metal parts of the equipment.
