'''T-slot structural framing''' is a framing system consisting of lengths of square or rectangular [[extrusion|extruded]] aluminium, typically [[6105 aluminium alloy|6105-T5 aluminium alloy]], with a T-slot down the centerline of one or more sides.

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.
