CNC V-grooving channel milled into stainless steel sheet before bending

The difference is in the edge

Laser → V-groove → bend → weld → finish → inspect. One chain, one workshop, your drawing.

V-grooving vs normal bending

Design samples · louvers

Louver samples,
ready to build

Four louvers planned blade by blade: the elevation of the opening, the blade section to scale, one blade in 3D and the quantities. A geometric plan only: no airflow, rain or sun ratings are claimed.

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.

Z-blade privacy screen

Overlapping Z blades at 45° in a window opening: no straight-on view through, and the folded lips stiffen each blade.

What makes it different. The Z section is folded from flat sheet, so the blade length and lip sizes are free to suit the opening.

Where it is used

  • Window and balcony screens
  • Service yard and AC ledge screens
  • Stair-core openings

How it goes up

  1. Fix the U support channels to the wall or frame at the sides and between.
  2. Slide or set each blade into place and screw or rivet it to the channels.
  3. Work from the bottom up so each blade laps the one below.

What makes it different. The two lips turn a flat fin into a stiff C section, so a deep fin can be made from thinner sheet.

Where it is used

  • Façade fins and vertical sun breakers
  • Car-park fronts
  • Feature bands on towers

How it goes up

  1. Fix horizontal support channels to the façade structure at the spacing shown.
  2. Fix each fin to the channels through its back lip.
  3. Check the fins plumb as they go up; the even pitch is what makes the façade.

What makes it different. The blade angle and pitch are set together on the drawing, so the view through can be planned before cutting.

Where it is used

  • Rooftop plant and chiller screens
  • Generator (DG set) enclosures
  • Parking and service openings

How it goes up

  1. Fix the support channels to the frame.
  2. Fix each blade to the channels at the set angle with brackets or screws.
  3. Keep the blade ends clear of the frame by the clearance shown.

Sun-shade fins over a window

Level flat fins standing out over a window, laser cut from 3 mm sheet.

What makes it different. Flat fins need no bending; they are cut to any outline on the fibre laser and can carry a pattern of holes.

Where it is used

  • Shading over windows and shopfronts
  • Canopy blades
  • Pergola tops

How it goes up

  1. Fix brackets or support channels to the wall above the window.
  2. Bolt or screw each fin to the supports.
  3. Check the fins level before tightening.
