Descript

Roll forming is a continuous process that employs a series of paired roll tools to progressively shape a flat strip of metal into a desired profile. The process of progressively shaping the strip is called ‘Flowering’ as gradual change in shape appears on a continuous strip as it passes through different stages of the process.

Cold roll forming holds an edge over the other production methods as it is a continuous process that eliminates stage production, finishing and sub-assembly operations. It also offers the following advantages:

Complex geometrical shapes can be produced.

• Better consistency and accuracy are achieved.
• Versatility in thickness and length.
• Increased strength due to strain hardening.
• Lightweight with rigidity saves material and cost.
• Secondary operations can be combined in the continuous operation– speeds up production.
• Both ferrous and non-ferrous metals can be roll formed.
• Avoids secondary coating as galvanized, vinyl coated or plastic enclosed metal can be roll formed.
• Increased manageability.
• Maximum straightness.
• Closer tolerances.
• Better surface finish.

Cold roll formed products have already found their applications in various industries and are finding new applications everyday. They have replaced many conventional methods for the betterment.
