NO PRESS BRAKE NEEDED

Most of our folds are done by hand. You fold at home, using simple tools.

This applies exclusively to sculptures designed and developed by 4A Métal — does not apply to other products or sculptures resold on this site.

Cut parts shipped flat — you fold, assemble, and weld at home.

Designed, tested, and cut in our workshop. It's up to you to give it shape.

A second look, from a different angle

Same piece, different perspective — to see the sheet metal grain, the fold lines, and the proportions from every angle.

78 parts. One color per part. One bull.

Each part of the kit is cut separately from a 1.5 mm steel sheet, then numbered and engraved. In this overview, each color represents a distinct part — exactly what you will receive flat, ready to fold.

XXL Bull — numbered part placement, overview and detail per part

78 laser-cut parts · 112 folds according to indicated angles · 194 welds to form the final sculpture · 1.5 mm steel sheet.

Designed for manual folding

Each fold line is laser-prepared with a light system that guides and facilitates manual folding, without a press brake. You bring each fold to its final angle using simple tools (pliers, mallet, locking pliers depending on the areas).

This system comes from our real-world workshop trials and has evolved through several prototypes to reduce complex folds and simplify assembly.

Our manufacturing method: 3D model, DXF flat parts, folding, engraving, welding assembly

Two PDF files provided with the kit

You don't just receive cut steel: each part is documented, including folding and assembly.

Folder 1

Folding folder

One sheet per part: fold direction (towards you or away), suggested folding order, and location of welds with neighboring parts — the method detail is illustrated just above. Everything you need to advance piece by piece without getting lost.

Folder 2

Assembly guide

Numbered views from all angles and assembly order in 7 steps — see the overview above. Each part finds its exact position in the sculpture, and the areas using our positioning systems are identified so you can weld perfectly the first time.

These two folders are provided only with the steel kit. The cutting file (DXF) is available separately, see below.
