Ten profiles folded from one strip of sheet: six trims, reveals and channels, and four complex shapes that only V-grooving folds sharp. Each one shows the section with its sizes, where the V-cuts go, the part in 3D, where it is used and how it is fixed.
Why every sample is V-grooved
An ordinary press brake wraps the sheet round its tool, so the outside corner comes out round. We first cut a V along each bend line, leaving a thin web of metal, then fold: the sheet closes into the V and the corner comes out sharp. Each sample below shows where its V-cuts go.
Every sample has a sample ID to quote, a free PDF datasheet (no registration) and its CAD file on WhatsApp.
What makes it different. Seven bends, most only 8 to 12 mm apart: a press-brake tool cannot reach between them without crushing the last step, and each corner would come out round. V-cut first, every step folds sharp.
Where it is used
Door and opening architraves
Wall moulding and panel frames
Mirror and art frames
How it goes up
Fix a timber or metal ground around the opening.
Bond the architrave to the ground; pin through the back legs where they are hidden.
Mitre the corners at 45° so the steps run round without a break.
A square tube folded from one strip: four sharp outside corners and a hidden overlap, no weld on the faces.

What makes it different. Closing a box means making the last bends inside a nearly finished tube, where a press-brake tool can hardly reach. With a V-cut at every corner line, the box closes with four sharp corners.
Where it is used
Slim frame members and screen grids
Furniture frames and legs
Decorative grids and dividers
How it goes up
Cut to length and close the ends with end caps or a mitred joint.
Fix with hidden screws or brackets inside the tube where it meets the structure.
A U channel only 8 mm wide inside and 40 mm deep: a slim reveal or a slot for a glass or panel edge.

What makes it different. A standard press-brake punch cannot reach into an 8 mm slot 40 mm deep. With V-cuts at both bend lines, the narrow base folds with sharp outside corners.
Where it is used
Slim reveals and recessed light slots
Edge channels for 6 mm glass or panels
Shadow slots in ceilings
How it goes up
Fix the channel through the back of its legs before the boards go up.
Set the panel or glass edge into the slot with the gasket or tape its supplier specifies.
