Steel Beams are widely used throughout the construction industry when supporting heavy loads is required.

Commonly termed an “I” Beam because of its shape, beams provide great load bearing support when used horizontally or standing as columns.

BIT series beam bending machine ( profile bending machine ) can process a large quantitiy of universal beams for structural projects .

Another solid steel shape that BIT series profile bending machine can bend is Rail. Rail (aka Railroad rail) looks like split tee material with a “ball” on the top of the tee’s stem. Rail can be rolled in different configurations such as rail ball in, rail ball out and rail ball up.

Six Steps Of Curved Steel Beams

  • Steps 1#: Loading steel beams – the steel beam is inserted in between the top roller and the right lower roller. The steel beam can be supported if necessary and is not subject to deformation stress.
  • Steps 2#: The right lower roller up to the top roller movement achieves the pinching position – the steel beam is blocked in between the rolls and can be moved forward and backward rotating the rolls. The pressure exercised is lower than the one necessary to deform the profile.
  • Steps 3#: Pre-bending between the top roller and the left roller – the right roller slowly rises, starts rolling, and performs pre-bending between the top roller and the left roller.
  • Steps 4#: Working phase – in this phase the pressure increases and the deformation of the profile takes place, by translation of the profile and movement of the rolls.
  • Steps 5#: Pre-bending between the top roller and the right roller – The left roller is down and the right roller is raised. The steel beam is sent to the left and the three rolls begin rolling, pre-bending between the top roller and the right roller.
  • Steps 6#: Unloading of the steel beam – the pressure on the steel beam is eliminated and is increased the space between the rollers so that the steel beam can be extracted from the profile bending machine.

Notes

It is clear that, in order to load the steel beam on the profile bending machine/Beam Rolling Machine, a sufficient distance between the rollers must be present. It is also clear that, in order to block the profile in between the rolls and to apply pressure, it is necessary that this distance is reduced. Une or more rollers must be capable to move with respect to the others.

Roll Bending H-Beam & I-Beam Profiles: BIT series profile bending machine has the ability to roll to every configuration . Beam and wide flange are both bent by BIT series section bending machine, from the very small sizes to the very large sizes. Its ability to bend wide flange and I-beam the easy way (against the weak axis) and the hard way (against the strong axis).

With PBH Profile Bending Machine able to bend the gamut of steel beam types including;

  • W-Beams (straight flange)
  • I-Beams/Junior Beams (tapered flanges for strength)
  • S-Beams (sloped inner flange, “American Standard” beams)
  • H-Beams (longer flanges)

Because we have up to 10 model PBH profile bending machines for curved steel beams, we make sure that we commend the profile bending machine/I Beam Bending Machine best fit for your job to reduce your cost and minimize tangent/trim at the ends(Unbend flat end).

Unbendable flat end

When beams are run through any profile bending machine there each end of the beam has a length that can be unbent, because it is not in contact with the top roller. This part of the residual unbend flat is difficult to completely eliminate during the roll bending process, and it is easy to produce quality and equipment accidents, so it should be prevented.

When bending on a common profile bending machine(symmetrically bending), the remaining unbend flat is usually about half of the center distance of the lower roller, which is also related to the thickness of the beam. With the PBH Profile Bending Machine(asymmetrical bending) the unbend flat end is approximately 1/6 to 1/10 of the symmetrical bend.

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.
