Family overview
What are AISC MT Tees?
AISC MT-shapes are miscellaneous tees cut from M-shapes. They follow a depth × weight designation pattern and serve specialty framing needs when an M-derived tee is required. Use tabulated stem and flange dimensions for detailing. This hub filters the finder to MT tees for comparison and calculator handoff.
Designations
Understanding MT Tees designations
MT6×5.4
MT designations follow the depth × weight pattern, such as MT6×5.4, derived from the parent M-shape series.

Questions & answers
MT Tees FAQs
What is an AISC MT-shape?
An MT-shape is a miscellaneous tee cut from an M-shape.
How does MT differ from WT?
MT tees come from M-shapes; WT tees come from W-shapes. Available sizes and geometry differ.
