What are the parameters of the third generation lean pipe?

What are the parameters of the third generation lean management? The third generation lean pipe mainly adopts aluminum alloy material (such as 6005T6 model), and the common parameters are as follows:

Specification range
Outer diameter: commonly 28mm (such as 28 × 28 × 1.2mm, 28 × 28 × 1.7mm, etc.).
Wall thickness: There are two mainstream thicknesses: 1.2mm and 1.7mm.
Length: Standard 4 meters per piece.
Material characteristics
Material: Aluminum alloy (such as 6005T6), surface treated with anodizing, with permanent anti rust and anti-corrosion properties.
Fasteners: Made of die cast aluminum material to enhance hardness and load-bearing capacity.
application characteristics
There are various types of compatible connectors that support diverse assembly methods.
Suitable for scenarios such as assembly lines and storage shelves.
