Your sheet metal parts,
cut, bent, assembled
Laser, punching, bending and assembly — in thin sheet as in thick plate, from prototype to series. A single point of contact, a network of workshops sourced and controlled in France, with no tooling to finance.

From the thin enclosure to the thick frame, every sheet has its rules
Thin sheet hinges on aesthetics, edges and flatness; thick plate on cutting, bending tonnage and distortion. The right process and the right workshop change the price and the lead time. CadNov steers and pilots.
No tooling
Cutting + bending: no tool to finance, ideal from prototype to series.
The right process
Fiber laser, punch or plasma depending on thickness.
Finished assembly
Welded/screwed assembly, insertion, coordinated finishing.
One contact
A project manager, from the blank to the finished part.
Integrator: the right workshop for the right thickness
CadNov is not an in-house sheet-metal shop — we are your integrator: we steer your part to the workshop equipped for your thickness and series, coordinate assembly and treatments, and inspect in France.
- Sheet-metal design advice (radii, flat pattern, accessibility)
- Workshop sourcing: fiber laser, precision and large-capacity press brakes
- Welded, screwed, riveted assembly, self-clinching nut insertion
- Coordination of finishes (paint, galvanizing, anodizing…)
- Material optimization (nesting) and cost
- Receiving inspection in France, traceability, reports
6 processes, from cutting to assembly
Fiber laser cutting
Precise and fast on thin to medium sheet, steel, stainless, aluminum.
Punching
Holes, repetitive shapes, local deformations (embossments, vents).
Plasma / oxy-fuel cutting
Heavy thickness, large formats, economical throughput.
Bending
Press brake: precision on thin, high tonnage on thick.
Assembly
Welding, screwing, riveting, self-clinching nuts, mounting.
Finishing
Deburring, shot blasting, painting, sub-assembly mounting.

Thin sheet or thick plate?
Two trades within sheet metal work. We steer your part to the right one — neither a precision laser for 20 mm, nor oxy-fuel cutting for a thin cover.
| Criterion | Thin sheet | Thick plate |
|---|---|---|
| Thickness | ~ 0.5 to 3 mm | ~ 3 to 30 mm (and more) |
| Cutting | Fiber laser, punching | High-power laser, plasma, oxy-fuel |
| Bending | Precision press brake | Large-capacity press brake (high tonnage) |
| Applications | Enclosures, covers, casings, thin sheet metal | Plates, frames, heavy brackets, boilermaking |
| Tolerances | tight, aesthetic requirement | wider, structure priority |
| Watch points | edges, flatness, marking | distortion, cutting time, straightening |
All sheets, thin and thick
Thicknesses from 0.5 to 30 mm depending on the process and workshop.
Steels
DC01 (thin), S235 / S355 (structure), pickled steel.
Coated steels
Galvanized (DX51D), pre-painted — protected from the raw material.
Stainless steel
304 / 304L, 316L — food, outdoor, decoration.
Aluminum
5754, 5083, 6082 — lightness, outdoor.
Brass · Copper
Decoration, electrical, connectors.
Other?
Heavy thicknesses, special grades: depending on application.
Cutting and bending precision
- Precise laser cutting, clean edges
- Bending tolerances (angle and flat pattern) controlled
- Welded-construction tolerances (EN ISO 13920)
- Flatness controlled, especially on thin sheet
Inspection
- Dimensional inspection, fixtures
- First article (ISIR) on recurring parts
- Material certificate EN 10204 3.1
- Receiving in France before delivery

Which surface protection / finish?
| Besoin | Solution | Substrat | À savoir |
|---|---|---|---|
| Corrosion protection from the material | Galvanized / pre-painted sheet | steel | protect cuts and welds |
| Corrosion protection after manufacturing | Zinc plating (thin) / hot-dip galvanizing (thick, outdoor) | steel | hot-dip galvanizing can distort thin sheet |
| Appearance / color | Paint, powder coating | steel, aluminum | any RAL |
| Stainless: appearance + corrosion | Graining / brushing, passivation | stainless | no zinc plating on stainless |
| Aluminum: deco / hardness | Anodizing | aluminum | — |
| Preparation before painting | Deburring, shot blasting | steel | adhesion and safety |
Cut cost from the drawing
Bend radius
A radius ≥ thickness avoids cracks and marks.
Minimum distances
Respect edge/bend/hole: otherwise distortion during bending.
Bend order
Check tool accessibility (collisions).
Inserts rather than tapping
On thin sheet, prefer self-clinching nuts.
Optimize the blank
Nesting reduces scrap: a big cost item in sheet metal.
Realistic tolerances
Don't demand machining tolerances on bent parts.
Inspected in France, committed ESG approach
Today, our guarantee rests on inspecting parts in France before delivery. In parallel, CadNov is gradually rolling out ESG criteria at its partners, starting with the low-cost supply chain.
Inspection in France
Receipt and check of parts in France before shipping. Real and verifiable.
Workshop selection
Technical qualification, capacity, quality: known, monitored partners.
ESG being rolled out
Environmental and social criteria being integrated — an approach, not an acquired label.
From prototype to series
- One-off part, prototype, small and medium series
- Ready-to-mount sub-assemblies
- Framework agreements for recurring parts
- Scheduled deliveries, stock on forecast
