Roll bending

How three or four rolls apply progressive force to shape plate and profiles, and what determines the final geometry, the fundamental process behind curved steel structures: from cylindrical shells to large-radius arcs.

Process

From flat material to finished curve. How roll bending works in practice: material feed, roll positioning, multi-pass sequences, and the factors that separate a precise bend from an expensive scrap piece.

On curving structural profiles - beams, channels, angles, tubes, and custom extrusions - for architecture, infrastructure, and industrial applications. How cross-section geometry affects the process and what to consider when specifying curved sections.
