Good Practice Guidelines for Rollforming
Use panel designs with large bend radii. It is possible to design architecturally desirable,
deep profiles, and at the same time, use large bend radii.
Design the rollformer so that profiling occurs from the center of the sheet out towards the edges.
Design the rollformer to accommodate the strength of the steel grade. For example, a higher strength
steel may require more rollformer stands to successfully produce a given profile.
Use lower strength steels to allow greater design latitude when making more complex profiles.
Maintain the rollforming equipment to achieve proper vertical and horizontal tooling alignment, as well as
adequate clearance between the mating top and bottom spindle rolls to avoid abrading the coating.
Clean the rolls to avoid damage to the paint finish.
Incorporate the appropriate number of rollforming stages to ensure smooth transitioning of bends.
Use flexible paint/primer systems to maximize performance at bends.
