In the non-standard automation industry, the most commonly used basic frame is the aluminum profile frame, also called the industrial aluminum profile frame. Industrial aluminum profiles are easy to cut, can be assembled in diversified ways, are light, and have short delivery times. The advantages have been widely known in the automation industry. We often hear that industrial aluminum profiles are divided into national standard aluminum profiles and European standard aluminum profiles, so what is the essential difference between these two?

First of all, for the national standard or European standard aluminum profile, the alloy composition of the aluminum alloy profile is actually the same. Whether it is the European standard industrial aluminum profile or the national standard industrial aluminum profile, it is generally 6063-T5 aluminum profile, which is the most A commonly used industrial aluminum profile material.

Secondly, for the national standard or European standard aluminum profiles, the surface treatment can also be the same or different. This is all made according to the different requirements of customers. The most commonly used on the market is the natural silver white oxidation, or aluminum natural color. Oxidation.

Third, whether it is a national standard aluminum profile or a European standard aluminum profile, the most commonly used sizes such as 1530, 2020, 303.0, 4040, 4545, 5050, 6060, 4080, 8080 and other specifications are the same.

So what is the essential difference between the national standard aluminum profile and the European standard aluminum profile? In fact, there is only one point that can be directly judged, and that is the inner notch for the lock screw.

The inner groove of the European standard aluminum profile is like a long trapezoid. Because of its relatively large inner width, the commonly used aluminum profile accessories such as nuts and bolts are also wider

The internal groove structure of the national standard aluminum profile is not so wide but relatively deep, and the cross section looks a bit like a regular "U" shape.
