Laser marking and engraving of metal parts
We identify parts, batches, logos, codes and technical references with permanent, clean and legible marking on a range of metals.

What is laser marking?
Laser marking writes the information directly onto the metal, with no ink, adhesive or label that can come away. The mark is part of the component and survives handling, cleaning and industrial use.
It answers the need for traceability: knowing which part this is, which batch it came from and which drawing it belongs to throughout its service life. It is also used to mark product identity with a logo, or to add machine-readable codes for production control.
It can be applied to parts we have manufactured ourselves or offered as a service on existing parts, and it fits into the same workflow as every other process.
Materials and thicknesses for laser marking
Metals and sheet thicknesses we work with as standard. If your industrial project needs a material that is not in the table, say so in your enquiry and our engineering office will confirm whether we can handle it.
This service works with the same materials and thicknesses as the rest of the plant. The full table is on the Sheet metal laser cutting page.
CAD file formats accepted for quoting
- DXF
- DWG
- STEP / STP
- STL
- IGS / IGES
- PNG
- JPG
With DXF, DWG or STEP we work straight from your file geometry: no need to redraw the part, and the quote comes back sooner.
We do more than check the drawing: we advise you on nesting (how the sheet is used) so you get the lowest possible price per part before anything is cut.
How our engineering office works
If you would rather not fill in the form, send the drawing straight to cata@catagermans.com.
Confidential handling. Your drawings are only used to prepare the technical assessment and are not shared with third parties. If you need a signed non-disclosure agreement, send it over.
Technical capabilities for laser marking
| Mark types | References, serial numbering, logos, codes and technical text |
|---|---|
| Materials | The same metals we laser cut |
| Durability | Permanent marking, integral to the material |
| Volumes | From a single part to full batches |
Applications and types of custom metal parts
- Traceability of parts and manufacturing batches.
- Serial numbering and drawing references.
- Logos and brand identity on finished product.
- Codes for production control and maintenance.
- Technical or assembly instructions marked on the part itself.
Sectors we manufacture for
We manufacture for industrial companies across very different sectors. These are some of the most common ones, but not the only ones: if yours is not listed, tell us about the part and we will confirm whether we can make it.
- Automotive
- Food industry (stainless steel)
- Agricultural machinery
- Construction
- Steel structures
- Energy
- Street furniture
Why work with Catà Germans
- Every process under one roof
- Cutting, forming, machining, welding and finishing in the same plant. We handle the whole logistics side so you receive the parts palletised and protected at your own factory, anywhere in Catalonia and the surrounding area, on the agreed lead time.
- In-house engineering office
- We review the drawing before manufacturing and prepare production from CAD/CAM. If something does not add up, we ask you instead of interpreting it ourselves. And if what you have is a sketch or a question, we will help with that too: advice is part of the service.
- From drawing to finished product
- Some finishes, such as painting or zinc plating, are done with specialist workshops. We handle the coordination and deliver with our own fleet: a single order and a part ready to fit.
- Raw material in stock
- We keep sheet and tube permanently in stock, so many standard jobs can start without waiting for material.
- Over 65 years of the trade
- A family business founded in 1958, specialised in industrial subcontracting of metal parts. You deal directly with the people who make the part.
Frequently asked questions
Does the marking fade over time?
No. The laser acts on the metal surface itself, so the mark is not an added layer and cannot peel or fade the way a label or ink would.
Can you mark parts you did not manufacture?
Yes, this can be arranged as a standalone service. Send us the part and the content you want marked and we will assess feasibility and price.
Can each part carry a different number?
Yes. Laser marking supports variable numbering within a batch, which is what makes unit-by-unit traceability possible.
Which file formats do you accept?
We accept PDF, DXF, DWG, STEP/STP, STL, IGS/IGES and also PNG or JPG images. If you do not have a final drawing yet, send us a dimensioned sketch and we will review it all the same.
Do you make one-off parts or only production runs?
We handle one-off parts and prototypes as well as small, medium and large batches and repeat production. You can specify this in the quote request.
How quickly do you reply to an enquiry?
We send the technical response as soon as possible once we have the drawing and the part details.
Do you offer painting, zinc plating or other surface finishes?
You can include them in the order. These finishes are carried out with specialist workshops we work with regularly, but we handle the coordination and the transport: you place a single order and receive the finished part.
Can I combine several processes in one part?
Yes — that is the normal way we work. A part can go through laser cutting, bending, welding and finishing inside the same plant, under a single order and a single point of contact.
