V-Grooving & Bending
Precision V-grooving and calibrated press-brake bending in Jeddah - crisp, near radius-free folds for seamless cladding returns and repeatable angles.
Precision V-grooving and calibrated press-brake bending in Jeddah - crisp, near radius-free folds for seamless cladding returns and repeatable angles.
What it is
Calibrated V-grooving thins the metal along a fold line so panels return at a crisp, near radius-free angle - the difference between a sharp architectural edge and a soft, rounded one.
Capabilities
- Near radius-free folds
- Calibrated press-brake bending
- Repeatable, accurate angles
- Seamless cladding returns and trims

Where it is used
Cladding corners and returns, column wraps, trims and any surface where a sharp, seamless edge matters.
Quality control
Folded parts are first-article checked to a millimetre-accurate tolerance for angle and dimension before batch production.
V-grooving & bending — frequently asked questions
What is V-grooving and why is it used for cladding?
A V-shaped groove is machined into the back of the sheet before folding, so the fold closes into a crisp, near radius-free corner instead of a rounded bend. It is how cladding returns, column covers and box sections get sharp, seamless edges.
Which materials can be V-grooved and bent?
Stainless steel, aluminium and brass sheet. The sheet is grooved and then folded on a calibrated press brake, which keeps the angle repeatable across every panel of a project.
How accurate are the folds across a batch of panels?
Each fold is set on the press brake from the approved shop drawing and checked on the first-article panel before the batch runs, so returns and angles repeat from panel to panel.
Does bending happen before or after finishing?
Usually after cutting and before welding and finishing, so that the polished or PVD surface is never bent after coating. Where a design needs pre-finished sheet, protective film stays on through the fold.
