Understanding the Different Types of Holes in Industrial Aluminum Profiles

Through holes of industrial aluminum profiles

Through holes are commonly used installation holes in industrial aluminum profiles. 

These holes help to facilitate the allen wrench to reach in and tighten the bolts. 

It is important to note that there are two types of through holes: positioning holes and screw holes. 

Positioning holes are used for bearing positioning, while screw holes are used for directly screwing the bolts. 

Countersunk holes of industrial aluminum profiles

Countersunk holes are also known as installation holes. 

The primary purpose of these holes is to install cylinder head allen bolts, 

so that the bolt heads do not protrude on the surface of the industrial aluminum profile, 

affecting the aesthetics. These holes are commonly used in applications where a flush surface is required. 

Threaded holes of industrial aluminum profiles

Threaded holes are generally used to install decorative accessories, 

such as hinges and handles, on industrial aluminum profiles.

By drilling threaded holes on the surface of the aluminum profiles, it becomes easier to tighten the bolts.

This improves the ease of installation and maintenance of various types of accessories. 

Blind holes of industrial aluminum profiles

Blind holes are generally not through holes and are mainly used to install door catches. 

They can also be referred to as door catch holes. 

Blind holes are designed to hold the door catches in place and keep them secure. 

The installation of these holes helps maintain the integrity 

and security of the structure and provides a polished appearance. 

In summary, the different types of holes found on the surface of industrial aluminum profiles serve important functions 

that help enhance their stability and appearance 

while also facilitating the installation of various accessories and hardware. 

It is important to pay attention to the specific function of each type of hole

in order to achieve optimal results in the design and construction of industrial aluminum profile structures.
