View A Video on Roll Forming - A Quick Introduction
Examples of Roll Forming products include angle irons, aluminum angles and steel angles which are used in carpentry and building applications. Metal trim and metal channels are also widely used in construction, but they are also used in the manufacture of industrial, commercial and consumer products. Metal rings are used to embellish buttons on telephones, in elevators and even clothing. They also prevent hoses from disconnecting, street signs from falling and they secure lock hardware in doors. Metal wall panels can improve the appearance of a wall in an office, or it can protect a wall in a factory from flying debris or sparks. All of these roll formed products are produced in stock quantities by metal fabricators because of the constant, high demand for them. However, in the many cases in which a stock roll formed product is not appropriate, custom roll forming provides specialized products in large quantities and of uniform quality. Roll forming is a modular process; roll formers can be configured to produce all manner of metal shapes.![]() |

Roll Formed Part Terms
-
Piece of equipment that holds metal coil so the roll forming process may
continue uninterrupted while new material is attached to the coil.
- Secondary
processes performed in conjunction with roll forming.
- A deviation from a
straight line in a roll formed piece.
- Procedure in which heated flat sheet metal is transformed
into spiral coils.
- The process of deforming
metal at room temperature in order to increase strength and hardness.
- The system responsible
for providing the roll forming machines with power and moving the metal
coils through the machines.
- The ability of metal
to bend or form without fracture.
- The maximum
amount of stress a metal can accept without succumbing to permanent deformation.
- Deformation at the
end of a roll formed part.
- Piece of equipment
that connects two coils to permit the continuance of metal coils into
the roll forming machine.
- A metal in which
iron makes up a significant component.
- Mechanism that maintains
flatness of metal being fed into the roll forming machine.
- A metal that
does not contain iron.
- Permanent
changes in the shape of a metal that occur after pushing a metal piece
past its elastic limit. Deformation is accomplished through the application
of stress.
- The process of cleaning
steel coils in preparation for metal forming processes, such as roll
forming. The coils are subjected to hydrochloric acid that removes impurities,
such as rust, from the metal.
- Imperfections in
the metal coil.
- The
process of changing the rolls on roll forming equipment. This is a long,
costly procedure.
- In reference to
the edge of sheet or strip metal that results from cutting to width by
rotary slitters.
- Deformation in
a roll formed part that occurs when the roll forming process fails to
stretch a part past its elastic limit.
- Deviation from a straight
line in the horizontal plane measured after the part has been formed.
Sweep is caused because of incorrect horizontal roll alignment and/or
uneven forming pressure.
- The acceptable
variation from product specifications, such as cross-sectional dimensions.
- Removing metal scrap
from a metal formed part in order to maintain consistency among metal
parts.
- Deformation in a roll
formed part that resembles a corkscrew. Twists are caused by extreme pressure
levels created during the roll forming process.
- The maximum
stress which can be applied to a material without lasting deformation
of that material.
