T-slot structural framing


T-slot structural framing is a framing system consisting of lengths of square or rectangular extruded aluminum, typically 6105-T5 aluminium alloy, with a T-slot down the centerline of one or more sides. It is also known as 80/20 framing, after the company 80/20, Inc., one of the prominent T-slot framing brands, the name of which is based on the 80/20 principle. While there is no published standard defining this framing system, manufacturers have settled into two categories of product comprising several series each that is generally intercompatible across manufacturers.

T-slot framing is divided into metric and fractional 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 available as well which measure x by 2x - e.g. 40mx80mm for 40 series.
