30*30mm, this is its cross-section size and the origin of its name “3030”.
Product length: usually 6m, but the length may be customized according to specific needs.
Slot width of 3030 aluminum extrusion:
This dimension is usually 8mm or 8.2mm (the extra 0.2mm is to facilitate the installation of accessories). Slot width is the width of the groove on the aluminum profile for installation of accessories (such as connectors, sliders, etc.).
Wall thickness of 3030 aluminum extrusion:
It may vary in wall thickness depending on the model and application. But it will generally be 1.5mm to 2.2mm.
Wall thickness is an important factor that affects the strength and load bearing capacity of aluminum extrusion. The thicker it is, the better the strength and load-bearing capacity, if it is used as a load-bearing structure, the wall thickness will be more than 2.0mm.

The thickness of the diagonal rib of 3030 aluminum extrusion:
It is generally 2.2mm, the diagonal rib is the part of the aluminum extrusion used to enhance the strength and stability of the structure.
Size of the center hole of 3030 aluminum extrusion:
The center hole is a round hole on the 3030 aluminum for mounting bolts or other fasteners. And its size is usually 6.8mm with a diameter length of 6.8mm. because it is round so commonly used diameter length is standard.
