Due to its high output, section rolling is today the most common production method for making open and closed section. Every car, house , factory, office and highway contain many varieties of roll formed metal sections. Increasing demands for high strength lightweight structural components require more and more complex cold rolled sections made from thinner gauges and higher tensile materials.
The roll forming process involves passing a flat strip of rolled metal coil through a series of shaped rolls progressively forming the metal to achieve the section profile shape. This process produces profile shapes with high precision and dimensional accuracy in almost any length from a wide range of materials.
Large variety of shapes
High load capacity to weight ratios
Integration of the punching/perforating processes into the roll forming process
Sections produced in materials with various surface finishes e.g. pre-coated strip
Lower production costs
An almost limitless variety of cross-sections can be produced using this process. Generally roll formed sections are divided into two main categories
Standard sections such as channels, “top hat” and purlins
Complex shaped sections.
For complex sections, the section manufacturer produces the cold rolled section in accordance to the end users specification. This requires a specially designed and manufactured set of rolls.
Our roll designer's expertise, combined with our state of the art design software and technology allows Bowers & Jones to design and manufacture complex shapes from exotic material. Using COPRA® FEA simulation software we can graphically demonstrate the end results and give the customer 100% confidence in the design. The skill of the designer combined with these tools means the design process can be optimised and the most cost effective design and manufacturing solution be found.
