Equal-leg T-sections (EN 10055, formerly DIN 1024)

Standard: EN 10055 formerly DIN 1024

Hot-rolled tees with the stem as deep as the flange is wide, designated T h × b in millimetres. Flange and stem have the same thickness. They are used for glazing bars, frames, window and door profiles, light stiffeners and general fabrication.

e is the distance from the outside of the flange to the centroid; the x-x axis is parallel to the flange.

T 20 × 20 to T 140 × 140

Notes

Section properties are calculated for the nominal dimensions. Mass is for a density of 7.85 kg/dm³.
T 75 × 75 is a mill size between the EN 10055 steps of 70 and 80.
