Metal Bar straightening solutions 

Specialist methods for every project

We understand that the straighter a bar is before being ground or turned, the better the final product. With this in mind, we offer three different methods of straightening material: Stretch Straightening, Bump Straightening, and Reeling.

• Our stretch straightening machine can handle sizes from 8 mm (0.314”) to 50.8 mm (2”) diameters and flats.
• Our bump straightening machine can handle sizes from 25.4 mm (1”) to 152.4 mm (6”) diameters or squares.
• Our two reeling machines can handle a size range of 7.2 mm (0.286”) to 80 mm (3.150”) diameter, with our larger machine being able to take lengths of up to 6 metres.

For tougher materials, or those with low tensile properties when cold, we also have the capability to heat material before it is straightened. Bars are heated in our furnaces to a workable temperature before being removed one at a time for straightening; this prevents any snapping or cracking occurring whilst the material is put under strain. If you're unsure of what bar straightening means for your end product, the team at Pro-Roll Ltd can explain. Simply give us a call to learn more.
