PBH T-Beam Bending Machine
T-Beams, formed by longitudinally splitting a standard beam, can be efficiently bent using the PBH Section Bending Machine, serving a multitude of industrial applications.
The PBH Section Bending Machine excels in precision manufacturing, accurately producing rolled t-beams with specific tolerances and impressive repeatability. Our profile rolling machines grant you the flexibility to select the appropriate equipment and tooling dies, enabling the shaping of t-beams to your desired radius.
Capable of bending large t-beams with minimal distortion (which may occur to some extent during the bending process), our machine’s proficiency lies in matching your project to the optimal rolling equipment, thereby reducing material loss during trimming and overall costs.
Bending orientations vary based on the relative sizes of the web and flanges. The PBH Section Bending Machine can bend T-beams:
- The easy way – typically with the beam web facing outward.
- The hard way – typically with the beam web facing inward.
- Beam web up (perpendicular to the bending radius).
Our machine fabricates rolled t-beams while minimizing natural material distortion across all orientations.
Additionally, the PBH Section Bending Machine offers rolling of t-beams involving multiple bends or with multiple variable radii.

|Minimum Inside Diameter (mm)
T-Beams, also known as T-sections or tee-beams, are structural steel beams characterized by their cross-sectional shape resembling the letter “T.” These beams consist of a central vertical section called the “web” with horizontal sections, called “flanges,” extending on both sides. The T-shaped configuration provides T-Beams with excellent load-bearing capabilities and stability, making them vital components in various engineering and construction applications.
T-Beam Bending refers to the process of bending or curving T-Beams to achieve desired shapes or configurations while maintaining their structural integrity. This process typically involves using specialized machinery, like profile bending machines, to manipulate T-Beams into curved forms without compromising their strength or functionality.
Applications of T-Beams and T-Beam Bending:
- Construction and Structural Engineering: T-Beams are extensively used in the construction of buildings, bridges, floors, and other structural elements. They provide robust support and stability to structures.
- Architectural Design: T-Beam Bending allows for innovative architectural designs, enabling the creation of curved or arched elements in buildings or other architectural structures.
- Industrial Machinery and Equipment: Curved T-Beams can be employed in heavy equipment, machinery, and industrial applications where specialized shapes are required for structural components.
- Infrastructure and Transportation: T-Beams find applications in infrastructure projects like highway overpasses, railway bridges, and other transportation-related structures due to their load-bearing capabilities.
- Roofing and Canopy Structures: Curved or bent T-Beams are utilized in roofing systems and canopy structures, offering both functionality and aesthetic appeal.
T-Beams and T-Beam Bending play crucial roles across diverse industries due to their structural strength, versatility, and the ability to create custom curved shapes to suit various engineering and architectural needs.
T Sectional Steel (or tee beams)
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.
Tee is made from taking a standard length of wide flange material and cutting the web to result in 2 lengths of tee material.
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.
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.

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
