Our common industrial aluminum profiles have more than a dozen standard series specifications, and there are only dozens of standard models, but there are nearly 200 kinds of specifications and models with letters. Then the question is, what is the difference between industrial aluminum profiles with letter models?
The industrial aluminum profile with letters at the back actually belongs to the extension model of the standard model, which is actively developed by the manufacturer with full consideration of the needs of users. Take the 3030 industrial aluminum profile as an example. There are many models of the same specification with letters behind them. Let’s give two examples below.
3030G
- Groove Width: 6mm
- Weight per Meter: 1.29 kg
- Thickness: 2.5mm
- Standard: National Standard Series
3030R
- Groove Width: 8mm
- Weight per Meter: 1.1 kg
- Thickness: 2.2mm
- Standard: European Standard Series (Arc Shape)
3030 (Standard)
- Groove Width: 8mm
- Weight per Meter: 1.05 kg
- Thickness: 2.2mm
- Standard: European Standard Series
Key Differences: Letter Models vs. Standard Models
By comparing the models of these industrial aluminum profiles, we can easily find the difference between the model with letters and the model without letters.
There is a notable difference between 6-slot and 8-slot configurations depending on the model variant.
Thicker and heavier industrial aluminum profiles offer superior bearing capacity, though they come at a higher cost.
The industry is divided into National Standard and European Standard. Some profiles feature circular arc shapes; others have only three or two faces.
