What diameters and thicknesses do you bend?

We bend tubes from Ø 10 mm to Ø 90 mm, in thicknesses from 1 mm to 6 mm, depending on material and application.

What is the minimum bending radius?

Our minimum radii depend on the material and diameter, but we can reach up to 1.5 × diameter in steel and 2 × diameter in aluminum.

Do you work with customer's material?

Yes, we can bend customer-supplied tubing or we can bend our own tubing for complete projects.

What is the usual delivery time?

For samples or prototypes, the lead time is usually 5-7 working days. For industrial series, 2-3 weeks, depending on volume.

Carbon Steel Welding | COES SL - Industrial Precision and Robustness

Steel welding with industrial quality

At COES we have more than 30 years of experience in carbon steel welding, using both manual and robotic techniques. We offer safe and durable joining solutions for sectors that require precision and resistance. Our technical team at Terrassa (Barcelona) guarantees consistent results adapted to every need.

What is carbon steel welding?

Welding consists of joining two or more pieces of metal by means of heat and filler material. At COES we specialize exclusively in welding. d'acer al carboni, the most widely used material in metal structures, industrial equipment and technical components. We work with processes manuals (MIG/MAG or TIG) i robotitzats to guarantee both quality and repeatability in large productions.

Types of welding we perform

Manual welding

Ideal for parts that are difficult to robotize due to their size or geometry. Our qualified welders master MIG/MAG and TIG techniques, adapting to each geometry or project requirement.

Robotic welding

Ideal for large series, where speed and precision are required.

Welding equipment

We have a versatile machinery park that includes:

Manual MIG/MAG welding stations for versatile jobs
TIG equipment for cleaner and more technical welds
Automated welding robots with positioners
Customized tools for serialized fishes

Sectors that need our welding

Automoció: xassis, reinforcements, supports and welded structural components.
Industrial machinery: structural fishes and vàris components.
Metal construction: metallic structures and subassemblies.
Commercial equipment: xassis for supermarket carts, Stackers and components for exhibitors.

Advantages of welding with COES

Wide experience in welding. Knowing the usual problems and their solutions.
Total flexibility: manual or robotic welding
Certified screeners and validated processes
Resistant, clean and non-deforming joints

Frequently asked questions about carbon steel welding

What is the difference between manual and robotic welding?

The manual one is better adapted to large or difficult to automate fish, while the robotized one offers more speed, precision and repeatability in series.

Do you accept welding work from customer's material?

Of course. We can work with our own materials as well as with pieces supplied by the client, depending on the project.

Can I send you a design to validate its feasibility?

Yes, you can send us a plan or sketch and our technical team will review it. We also offer recommendations to facilitate the process.

Can you make small series or prototypes?

Our company is specialized only in the manufacture of large series, however, as part of the project, we also make the prototypes and the necessary pre-series.
