MT4x3.25 – MT Shapes

MT4x3.25 is a tee 4 in (102 mm) deep with a 2.28 in (58 mm) flange, weighing 3.25 lb/ft (4.8 kg/m).

MT shapes are structural tees split from M shapes, carrying the lighter weights and smaller sizes available in the M series. They serve the same general purpose as WT shapes — truss chords, light built-up sections, and miscellaneous fabrications — wherever a lighter, smaller tee section is more appropriate than one cut from a full-size W shape.
