A V-groove is cut into the back of the sheet along the fold line, leaving a thin skin of material. When the sheet is folded, that skin closes into a corner with almost no radius — the edge an architect draws, rather than the rounded one a press brake produces. The finished face is never touched, which is why the process suits mirror, hairline and PVD-finished sheet.
What gets V-grooved
- Column cladding and wraps — sharp-cornered wraps for lobby columns and lift portals, folded to fit the structure on site.
- Wall panels and cassettes — large decorative panels with folded returns, where a rounded edge would read as a mistake.
- Door and frame details — architraves, reveals and frame profiles in finished sheet, folded to a crisp line.
- Furniture and joinery metalwork — reception counters, display plinths and cladding to joinery, matched to the designer’s drawing.
Why V-grooving
A press brake bends metal around a radius. On a bracket nobody minds; on a lobby column in mirror stainless the eye finds it at once. V-grooving removes material along the fold line so the sheet closes into a true corner, and because the groove is cut from the back, the decorative face arrives untouched. It is slower than plain bending, and it is the right process for a smaller set of jobs — the ones where the corner is the detail the client will look at.

From your file to a folded panel
- Send your drawing — elevations and sections; DWG, DXF or PDF, with the finish named.
- We confirm material and layout — grade, thickness, finish, and how the panel breaks into pieces for handling and installation.
- Grooving and folding — the fold lines are grooved from the back, the panel is folded and the corners are checked.
- Downstream, if you need it — welded returns, protective film, PVD or polishing on the same order.
