PBH T-Beam Bending Machine
T-beams also called T-sections, formed by longitudinally splitting a standard beam, can be efficiently bent using the PBH Section Bending Machine, serving many 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), the PBH section bending machine’s proficiency lies in matching your project to the optimal rolling equipment, thereby reducing material loss during trimming and overall costs.
Three Bending Methods of T-beam
Bending orientations vary based on the relative sizes of the web and flanges. The PBH Machines 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.

What is?
T beams can withstand large loads. They get their shape (and name) from the fact that they do not have a bottom flange.
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 is made by taking a standard length of wide flange material and cutting the web to result in 2 lengths of T beam material: 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.
T-beam bending
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.
How to Bending?
Bending the T-beam using a section bending machine is very similar to bending angle profiles
Just like wide flange carbon T-beam is classified as ASTM A992 resulting in a yield point (psi) of 50,000 minimum.
The most common bending method for bending T beam material is a roll bend or pyramid bend method. Straight material is inserted into the rollers; the rolls are then moved horizontally to put the desired radius into the material. The rolling(we call profile rolling) of the T beam is actually very similar to the rolling angle(video of angle profile bending).
Applications
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.
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.
- Construction and Structural Engineering: T-Beams are widely utilized in the construction of buildings, bridges, floors, and other structural elements. They provide strong support and stability to structures.
- Architectural Design: T-beam bending allows for innovative architectural designs, enabling the incorporation 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 necessary for structural components.
- Infrastructure and Transportation: T-Beams find applications in infrastructure projects such as highway overpasses, railway bridges, and other transportation-related structures due to their ability to bear heavy loads.
- Roofing and Canopy Structures: Curved or bent T-beams are utilized in roofing systems and canopy structures, providing both functionality and aesthetic appeal.
Straighten T beam
There are primarily two ways to straighten the T beams: ramming and rolling. In the former case, a hydraulically powered ram pushes on the T beam when the T beam is held at two ends. By repeatedly applying pressure along the length of the curved T beam, it can be straightened.
A quicker and more effective way to straighten T beams is with a cold roll forming machine. The curved steel T beam 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 T beams 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.
Tolerance Of T beam
- Quality Of Finish: Depending on the size, T beams are either split using a shearing process or a flame cutting process.
- Shared T beams: 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 T beams: Usually 2/3 mm loss of width per cut. T beams are supplied as cut. When reversing the T beams to produce tapered T beams the loss of width is compunded and some remedial welding may be necessary to achieve your exact width.
- Straightness of T beams: T beams are straightened to BS 4/N.S.S.S tolerances. Finer tolerances can be achieved at cost.
- Length tolerance: Plate Cutting tolerances are +/- 3mm
