Section Bending Tees

T Sectional Steel (or tee beams)

Profile bending machine bending the stainless steel tees

T beams can withstand large loads. They get their shape (and name) from the fact that they do not have a bottom flange.

T section steel is also sometimes referred to as just a ‘flange beam’ or a ‘web and flange’ or even a ‘flange and web’ beam. All these names highlight the fact that it is “missing” a second flange, which is typical of I beams.

Tees Bending
Bent tee

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 can bend all types of Tee including aluminumstainless and carbon steel.

Application of T Sectional

Steel t-sections are often used in steel roof trusses to form built-up sections. The lack of a bottom flange is cost-effective in terms of needing fewer materials, but there is a trade-off. T beams are not as strong as their I-beam equivalents.

How to section bending tee profiles

Bending tee using section bending machine is very similar to bending angle profiles

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.

Bending Profiles Tees

Section bending machine ability to bend tee sections from the very small sizes. It can bend the material with the tee stem in, stem out and stem down.

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.

Straighten steel tees

There are primarily two ways to straighten the tees: ramming and rolling. In the former case, a hydraulically powered ram pushes on the tee when the tee is held at two ends. By repeatedly applying pressure along the length of the curved tee, it can be straightened.

A quicker and more effective way to straighten tees is with a three-roll section bender (also called a “profile bending machine,” or an “angle roll.”). The curved steel tee is run through large rollers with smaller calibrating rollers until it is straight. The process is faster than ram straightening and provides superior quality. Mill tolerance for straightness of tees is 1/8in variation from straightness in ten feet. Ram bending can achieve this tolerance. With roll straightening, however, tolerances of 1/8in over 40 feet and longer can be achieved.

Tolerancce Of Tee Splitting:

Quality Of Finish

Depending on the size, tees are either split using a shearing process or a flame cutting process.

Shared Tees:

‘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.

Length tolerance:

Plate Cutting tolerances are +/- 3mm
