At COUTH, we have more than 70 years of experience in the design and manufacture of industrial marking systems in the steel industry. We specialize in developing highly efficient marking solutions for demanding sectors such as steel, where traceability and quality are crucial.
Identification in the steel industry goes far beyond the marking of metal parts, as it is the basis for ensuring traceability, quality control, and protection against counterfeiting. Each marked part can be traced from its origin to its final destination, complying with international regulations and ensuring the integrity of the supply chain.
If there is one thing that has been learned throughout industrial development, it is that all parts and components of the machinery used, as well as the objects produced by it, must always be tracked. Therefore, proper metal marking is one of the most effective and common practices during the production of various parts.
Thanks to this tracking, the effectiveness of each part or element produced can be accurately determined, and appropriate safety measures can be taken in the event of loss, defect, or failure. In fact, in the case of the steel industry, due to the materials it works with, such tracking is crucial.
At COUTH, we provide marking solutions for the most difficult environments, such as the marking of metal or steel parts at over 500ºC, with a special focus on the quality and depth of the legible mark, even after the cooling process.
At COUTH, we offer different solutions for marking metal structures.
If it is a question of complying with certain mandatory characteristics in order to obtain the CE marking according to the EN1090 standard, at COUTH we offer different solutions for marking metal profiles, by dot-peen, scribing, or laser.
At COUTH, we offer ad-hoc solutions for marking the steel profiles of high-voltage towers.
In the vast majority of cases, deep marking is necessary because they are subsequently coated. This coating is necessary to comply with CE marking standards, where components exposed to the elements must meet the durability requirements defined in standard EN1090-2.
As with many other parts in the steel industry, train rails can be marked hot or cold.
Our markers can perform deep marking at high speed. Our solutions can be integrated into the rail production process, cycle times are shortened, and therefore the return on investment is very short.

Automobile marking with the COUTH laser is known for its high speed.
Thanks to its stability and output power, it gives the part a high-performance result that is long-lasting over time.
If you’re looking for speed, a deep mark, and reliability, this is your best option.
The built-in technology makes it the fastest on the market.
When you need a silent and effective method, the scribe method for marking automobile parts is a must-have.
It uses a diamond or tungsten carbide needle for a precise, deep results that would be difficult to achieve otherwise.
Marking metal parts is a process in which an engraving or mark is made on the material containing a series of data, either in the form of text or numbers, which provide various information about the manufacture of the part itself.
The materials that can be marked are diverse, however, in the steel industry, marking on stainless steel and metals such as gold, for example, are processes that have been standardized.
At COUTH, we manufacture markers with different marking techniques for metal and stainless steel:
One of the most innovative techniques used in the metal marking industry in the steel sector, especially for mass production. This system uses a laser to mark the material with high precision. One of its main advantages is the exceptional durability of the machine, which ensures consistent performance over time.
Laser marking in the steel industry uses a focused beam of light to modify the surface of the steel, creating permanent, high-contrast marks. It can be done by annealing (controlled oxidation), engraving (removal of material), or color marking, depending on the type of steel and the type of laser.
Advantages:
Applications in the steel industry:
This is a metal marking technique that uses dot impact on the metal surface. This technique produces accurate markings that are easy to read on the part.
How does it work?
Dot-peen marking in the steel industry uses a carbide punch, controlled by CNC (Computer Numerical Control), which impacts the surface of the steel, generating a series of micro-impacts that form characters, numbers, or codes. The depth and density of the marking are adjustable.
Advantages:
Applications in the steel industry:
Using a tungsten carbide or diamond stylus, metal parts and even certain types of resistant plastics can be marked by making fine, highly precise incisions. It is also a silent marking system.

Industrial marking is a fundamental pillar of the modern steel industry. At COUTH, thanks to our experience and advanced technology, we guarantee marking solutions tailored to the identification, traceability, quality, and safety requirements of steel.
The choice of the right technology—laser, dot-peen, or scribing—depends on the specific requirements of each application, but all share the reliability, durability, and integration capabilities that characterize us as a leading company in the sector.
Traceability in the steel industry is a fundamental pillar for ensuring quality, safety, and efficiency throughout the steel supply chain, as it allows the history, application, and location of each product or batch to be tracked, from raw material to final product, using recorded data and standardized procedures.
According to ISO 8402, traceability is “the ability to trace the history, application, or location of a product using recorded data.” In the steel industry, this involves documenting each stage of the process: from the receipt of the ore, through smelting, rolling, heat treatment, to the delivery of the final product to the customer.
Traceability is achieved through systems that document and track every step of the production process, using technologies such as barcodes, RFID, scanners, and specialized software.
These systems automatically capture information about materials, operators, dates, and locations, ensuring comprehensive, real-time tracking.
For all these reasons, in the steel industry, traceability is not only a regulatory requirement but also a strategic tool for ensuring quality, safety, and competitiveness. Implementing effective traceability systems allows companies to anticipate problems, optimize processes, and respond quickly to any eventuality, consolidating their position in an increasingly demanding global market.
Marking stainless steel, as well as marking metal on items such as gold ingots, is now an essential step in both the steel industry and in manufacturing and assembly processes as such.
By marking metal parts, for example, a large amount of information can be obtained that will be useful not only for the traceability of the company that manufactures the product, but also for the entire life cycle of the part, from distribution to its final use.
In short, industrial marking in the steel industry is essential for:
What can a code marked on a part contain? Various information depending on the part itself: the date of manufacture and expiration date, the batch and serial number to which it belongs, and some other important characteristics to be noted in the marking.
There are many ways to identify materials and parts. Over the last few years, this technology has also evolved to adapt to current needs and those of each sector. Some of the most commonly used are:
The marking of metal parts in the steel industry is evolving rapidly, driven by the need for traceability, efficiency, and regulatory compliance. The immediate and medium-term future (2030-2035) will be marked by the adoption of smart technologies, process automation, and digital integration, enabling companies to respond to the challenges of quality, sustainability, and global competitiveness.
The trend is clear: to migrate from traditional methods to digital and automated solutions to improve efficiency and reduce human error.
