'''T-slot structural framing''', sometimes known as '''aluminum extrusion''', or '''2020 extrusion''' when the [[Cross section (geometry)|cross-section]] is 20x20 mm, is a framing system consisting of lengths of square or rectangular [[extrusion|extruded]] aluminum, typically [[6105 aluminium alloy|6105-T5 aluminium alloy]], with a T-slot down the centerline of one or more sides. The original design for T-slot structural framing was first seen in a 1986 US patent (#4,607,972) by Donald C. Hennick.

T-slot framing is divided into metric and fractional (imperial) categories. The T-slot is always centered along the long-axis of the piece. Pieces are available in each series with a square cross-section. Rectangular cross sections are also available which measure ''x'' by ''2x'' (where ''x'' is the defined width) - e.g. 40mm by 80mm for 40 series. |

T-slot structural framing is a framing system consisting of lengths of square or rectangular extruded aluminium, typically 6105-T5 aluminium alloy, with a T-slot down the centerline of one or more sides.
It is also known under several generic names, such as aluminium extrusion, aluminium profile and 2020 extrusion if the cross-section is 20x20 mm, alongside brand names, such as 80/20 framing.[1]
While the precise history of the T-slot framing system is not known, advancement in extrusion press technology in the early 1950s allowed for economic production of aluminium profiles,[2] and examples of use can be found from the early 1960s.[3]
Although no published standard defines the system, it is produced in a series of conventional sizes which allows for compatibility between manufacturers.
There is a variation on T-slot profiles known as V-slot rails where V-slot wheels are slotted into the V-shaped channels of the framing for linear motion in a 3D printer or other CNC machine.
Profiles
T-slot framing is divided into metric and fractional (imperial) categories. The T-slot is always centered along the long-axis of the piece. Pieces are available in each series with a square cross-section. Rectangular cross sections are also available which measure x by 2x (where x is the defined width) - e.g. 40mm by 80mm for 40 series.
Profile type |
Profile name |
Profile size |
---|---|---|
fractional | 10 series | 1" |
15 series | 1.5" | |
metric | 20 series | 20 mm |
25 series | 25 mm | |
30 series | 30 mm | |
40 series | 40 mm | |
45 series | 45 mm |
