The most common question from new customers revolves around our bending capacity with the PBC section bending machine, especially for I beams. While we can easily bend IPE 500 I beams the “hard way” (x-x axis) and the “easy way” (y-y axis) as well as IPE 700 the “easy way”—all on the PBC 700 section bending machine. But a more comprehensive answer considers various factors:
The web of a steel beam or channel is a vital component that connects the flanges, providing structural integrity. During the bending process, the material must undergo deformation without experiencing buckling or crippling. Buckling refers to the sudden failure of the beam due to excessive compressive stresses, while crippling involves localized damage to the web, affecting its load-bearing capacity.
The requirement for successfully bending steel beams or channels is that there is no buckling or crippling of the web.
Top 9 considers various factors
- Section Size: Lighter sections might pose more bending challenges than heavier ones.
- Orientation Capacity: Bending capabilities in different orientations: hard way (x-x axis), easy way (y-y axis), off-axis, with reverse curves, multiple radii, or bending in two planes.
- Radius: The tightness of the radius is a crucial factor in determining bending feasibility. (Typically, when bending beams, the heavier the weight of the beam the nicer the end product will be. Depending on radius and beam size, there can be distortion or shrinkage expected from the bending process. With our expertise in bending, we’re able to let you know what to expect and make suggestions for the best bent beam possible. )
- Radius Tolerances: Meeting specified tolerances for the desired part’s radius.
- Deformation Allowance: Whether the application allows for any deformation, and if so, the permissible amount.
- Excess Material: The requirement for excess material at each end for trimming.
- Starting Point: Many section bending machines initiate the process only after a certain straight section has moved through(PBC Heavy-Duty Double Profile Bending Machine’s double pinch type structure can execute the pre-bending at the ends of the profile, and produce the smallest straight section).
- Straight Tangents: Whether the beams involve straight tangents or not. (When beams are run through any bending machine there is a straight tangent on both ends of unrolled material that must be trimmed off before the final application. ).
- Quality Concerns: Instances where a company claims their produced section bending machine’s capacity to bend steel, but the resulting quality falls short of expectations.
Summary
In summary, the bending capacity of our PBC section bending machine, particularly for I beams, is a subject we address comprehensively to provide our customers with the most accurate and valuable information.
Quality concerns are at the forefront of our service. While some companies may claim bending capacity, the true measure lies in the delivered quality. We prioritize transparency, providing customers with realistic expectations and valuable suggestions for achieving the best-bent steel section possible.
