Cut — engraved lines
Laser-cut parts with engraved fold marks. You perform the folding yourself using your own method and equipment.
Geometric steel wall sculpture.
Industrial design by Rim Shamsin
Buying a simple DXF file and figuring it out on your own means finding a laser cutter, adjusting the thickness, managing folds, understanding angles, and fixing errors. It’s a real headache.
At 4A Métal, we deliver the complete solution: parts cut, numbered, engraved, optimized for the workshop, and provided with an assembly PDF. You save time, avoid errors, and assemble with peace of mind.
Same model. Same result. Choose your level of preparation.

Dashed micro-cuts
Small, discontinuous laser micro-cuts define the fold line and reduce the effort required. Depending on the part and the angle, folding can be done by hand, on the edge of a workbench, with pliers, or using a vise. No press brake needed.
The DASHED lines guide the fold precisely and reduce the necessary 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.

Examples of possible methods depending on the parts and folding angles. These methods only apply to option 2 — DASHED.
| Option 1 | Option 2 | Option 3 | |
|---|---|---|---|
| Laser cutting: | Yes | Yes | Yes |
| Fold marks: | Engraved | DASHED micro-cuts | Already folded |
| Folding performed by: | Customer | Customer | 4A Metal |
| Press brake required: | Depending on customer method | No | N/A |
| Easy folding: | Standard | Yes | Already done |
| Assembly / welding by customer: | Yes | Yes | Yes |
| Customer preparation time: | Highest | Reduced | Minimal |
| Folding to be done by customer: | Yes — customer's method | Yes — facilitated by DASHED | No — done by 4A Metal |
| Price: | Most economical | Intermediate | Full service |
Actual prices for each option are defined by the product variants in the shop.
Fold marks (engraved or DASHED, depending on the chosen option) are indicated on the provided plan. A clamp may be useful to hold certain pieces during assembly.
Positioning, tacking, welding, and finishing allow you to achieve the final geometry of the sculpture.
| Thickness | 1.5 mm |
|---|---|
| Sheet used | 125 × 233 cm |
| Material surface | 2.91 m² |
| Material | Raw steel, or Corten steel option (natural patina) |
| Finish | Design implemented on the visible exterior face of the assembled model |
| Design | Small parts for easy folding, regardless of the chosen option; design optimized for workshop production |
| Welds | Mostly on the exterior |
Folds are made at an approximate angle to allow for adjustments during assembly. Final adjustment may be necessary for a perfect result.
Since every workshop has its own tolerances, these adjustments allow for the final geometry to be achieved.
Because we are metalworkers before we are file sellers. We know what it means to deal with dozens of folds to adjust, a poorly conceived angle, or a badly numbered part. Our models are thought out for real production, not just for a 3D rendering.
