Cut — engraved lines
Laser-cut parts with engraved fold marks. You perform the folding yourself using your own method and equipment.
Industrial geometric steel sculpture.
Compact format, strong presence.
Buying a simple DXF file and figuring it out yourself means finding a laser cutter, optimizing nesting, adjusting thickness, recalculating folds, and understanding angles. It's a waste of time.
At 4A Metal, you receive the pieces pre-cut, numbered, with engraved fold lines, a production-optimized file, a PDF of folding angles, a welding instruction PDF, and an ultra-precise assembly PDF. Delivery included. You don't have to look for anything; you just assemble.
| Sheet metal required | 1 sheet of 106 × 125 cm |
|---|---|
| Total surface area | ≈ 1.3 m² |
| Thickness | 1.5 mm |
| Material | Raw steel, or Corten steel option (natural patina) |
| Finish | Drawing made on the outer visible face of the assembled model |
| Design | Parts dimensioned to facilitate folding operations |
| Welds | Mostly on the outside |
Fold lines are engraved. Depending on the chosen option, the angles are created with varying degrees of precision, leaving room for final adjustment during assembly.
Since every workshop has its own tolerances, a final adjustment may be necessary.
Same model. Same result. Choose your level of preparation.

DASHED micro-cuts
Small, discontinuous laser micro-cuts define the fold line and reduce the required effort. Depending on the part and angle, folding can notably be done by hand, on the edge of a workbench, with folding pliers, or using a vise. No need for a press brake.
The DASHED system precisely guides the fold line and reduces effort. The final angle remains under the user's control.
We cut and form the parts in our workshop. You receive the elements already folded, but still unassembled: assembly and welding remain your responsibility.

Actual prices for each option are defined by the product variants in the shop.
Fold marks (engraved or DASHED depending on the option chosen) are indicated on the provided plan. A clamp may be useful for holding certain parts during assembly.
Positioning, tack welding, welding, and finishing allow you to achieve the final geometry of the sculpture.
Optimized cutting, engraving included, provided technical PDFs, delivery included: everything is designed for surprise-free assembly.
