Section Bending Tees
Bent tee can be used for many different applications. The most common application would be as tunnel supports (shoring) or roof trusses used in steel construction.

Profile bending machine can ability to bend Tee, but you also have the ability to split beam into tee sections. When using profile bending machine to bend tee you do not have to find a secondary vendor to split the beam into tee prior to bending.
Tee is made from taking a standard length of wide flange material and cutting the web to result in 2 lengths of tee material.
Section bending machine ability to bend tee sections from the very small sizes and up to 12” stems (coming from 24” wide flange). It can bend the material with the tee stem in, stem out and stem down. The maximum tee weight that can bend would depend on the wide flange origin. Different weights of wide flange will result in different flange sizes and thicknesses affecting the upper capacity.
The most common bending method for bending tee material is a roll bend or pyramid bends method. Straight material is inserted into the rolls; the rolls are then moved horizontally to put the desired radius into the material. Rolling of tee material is actually very similar to rolling angle.
Just like wide flange carbon tee is classified as ASTM A992 resulting in a yield point (psi) of 50,000 minimum.
Angles are often used in tank stiffeners, matching flanges, curved lintels, hand rails, lagging rings, form work and fabricated roof trusses.
Tolerancce of tee splitting:
Quality Of Finish
Depending on the size, tees are either split using a shearing process or a flame cutting process.
'Sheared edge' smiliar to sheared plate. Additional grinding may be necessary depending on application. Some loss of width in addition to the normal beam manufacturers tolerance.
Flame / Plasma cut tees:
Usually 2/3 mm loss of width per cut. Tees are supplied as cut. When reversing the tees to produce tapered tees the loss of width is compunded and some remedial welding may be necessary to achieve your exact width.
Straightness of tees:
Tees are straightened to BS 4/N.S.S.S tolerances. Finer tolerances can be achieved at cost.
Plate Cutting tolerances are +/- 3mm
