Roll forming is a progressive process in which a coil of metal is shaped

by a series of rolls. Each shape will have a different set of rolls. Each roll

slightly changes the shape of the metal. When the metal reaches the end

of the line, the desired shape is achieved.

 

Roll forming produces high quality products quickly and inexpensively

compared to traditional press operations. Roll forming is ideal for

producing long shapes.

 

Almost any bendable material can be formed. Two materials can even

be formed together to form one shape.

 

Roll forming can be used to form all kinds of metal, not just aluminium.

Secondary operations such as notching, punching and post painting

can be eliminated. Thinner cross sections can be produced. Practically

any length can be roll formed.

 

Roll forming is a high speed production process that can produce uniform

cross sectional dimensions throughout the length of the part. Different

lengths can be made without trim scrap. Roll forming can eliminate

multiple stage operations.

 

Slit edges can be edge rolled to reduce the risk of accidents.

 

Roll forming is unique among all methods of forming metal. The most intricate of

one-piece forms emerge from progressive roller dies in a process called "flowering".

 

A flat strip of metal progressively takes on the most complex configuration in this

process.

 

Roll forming presents the designer with the utmost flexibility, frees him from

standard designs, and frequently eliminates costly subassembly and fabrication.
