Shapes and Flats
Rolling
Cold rolling changes the dimensions of material
by passing it between one or more pairs of driven
precision-ground rolls. The incoming material
conforms to the space between the rolls or to the
shape ground into the rolls.
Bekaert-Orrville’s cold rolling provides:
- Increased tensile, yield and hardness values by as much as 50% over hot rolling or machining. Cold rolling refines the grain structure of the material, which makes it harder and stronger.
- Excellent surface finish. Surface quality allows plating or painting with minimal surface preparation.
- Significant cost savings over machining. Processing is reduced while minimizing scrap.
Drawing
During cold drawing, material is pulled through a
carbide die or turk’s head in order to change its
shape and reduce its size. A number of draw passes
through successive dies may be required, depending
on the complexity of the specified shape. Each pass
further shapes and reduces the profile’s size until it
reaches the final cross section.
Bekaert-Orrville’s cold drawing provides:
- Closer tolerances than are obtainable from other cold-forming processes. Dimension tolerances can be held to +/- .0005" (+/- .0127mm).
- Sharp corners. Inside and outside radii can be held to .005" (.127 mm).
- Extremely complex and asymmetrical profiles. Virtually any profile is possible because dies can be produced in an infinite number of shapes.
- Significant cost savings over machining. Processing is faster with minimal scrap.

Sizes
Using cold rolling, cold drawing or a combination of the two processes, Bekaert-Orrville produces custom metal profiles with cross sectional areas ranging from .008" to .875 square inches (5.16 sq. mm to 564.52 sq. mm). For size ranges of the most common shapes, please refer to the chart below:
