Galvanized steel is one of the most commonly used metals in construction, automotive, and infrastructure development. That is because it has a protective zinc coating that makes it effectively resistant to weather elements and corrosion.
But this thin protective layer presents a challenge when it comes to adding permanent surface markings.
While aggressive marking methods like chemical etching and stamping may compromise the protection, others such as labeling and inking easily wear off or fade over time.
The best solution to this problem is to use laser marking on galvanized steel. With laser technology, businesses can get parts with durable, precise, and clear markings for their needs.
Laser marking on galvanized steel is a non-contact process that uses a highly focused laser beam to write markings on metal surfaces.
A laser beam of light alters the optical properties of the metal’s surface to create high-contrast markings.
Several laser technologies mark galvanized steel really well, but these two stand out:
| Fiber Lasers | This laser technology option comes at the top of the list as it delivers industrial-grade, precise, and durable markings faster. |
| MOPA Fiber Lasers | If very high-contrast markings are needed, then MOPA fiber lasers become a great option. It offers greater control over the pulse duration to mark galvanized steel without destroying its protective surface. |
Here’s what else’s worth knowing about laser marking galvanized steel.
Laser technology is a great method for marking metal. That is due to its ability to combine precision with permanence and speed.
Here are some of the biggest advantages of laser marking on galvanized steel.
One of the greatest benefits of laser technology is its ability to create permanent markings on metals. This is unlike ink, adhesive labels, and paintings, which wear off or fade with time.
Laser markings become a permanent part of galvanized steel, but maintain the metal’s resistance to abrasion, heat, moisture, chemicals, oils, and general wear and tear.
Laser marking produces consistent and detailed logos, serial numbers, QR codes, fine text, data matrix codes, barcodes, graphics, and identification symbols.
Even tiny parts made of galvanized steel receive crisp and readable markings that remain intact throughout the lifetime of the component.
Because the entire process is computerized, human error is minimized, and the markings are accurate and identical across production batches.
Laser marking technology requires very minimal manual human input to create markings. You do not need to waste time on cutting tools, engraving bits, or materials like inks and labels.
All that is needed is the appropriate settings for the target surface and a button press; the process then automatically begins and runs to completion.
Marking speeds can range from 200 to more than 15,000 mm per second, depending on the laser technology in use, material surface, and the marking details needed.
This means you get a scannable bar code onto galvanized steel parts in just a few seconds.
Laser marking of galvanized steel has several applications for businesses depending on the need. Here are some of the most common applications:
In modern manufacturing, it is required to make components traceable for quality control, regulatory compliance, and the management of supply chains.
Laser marking makes this possible through:
| Barcodes and Data Matrix Codes | For assembly lines and inventory management, laser marking creates high-contrast and easy-to-read 2D codes for automated camera reading. |
| Serial Numbers | To track life cycles, manage warranties, and conduct recalls effectively, laser marking etches permanent unit identifiers on galvanized steel panels. |
| Part Numbers | To streamline audits and sorting in warehouses, laser marking serves as a superior alternative to stamping, as it is faster to create, permanent, and easier to scan. |
Essentially, laser marking is a key component of effective asset tracking and management.
The construction industry greatly benefits from galvanized steel because it is strong and resistant to the elements. Quality construction happens with proper marking, and that is why laser marking remains the best option.
Laser marking labels structural components like beams, brackets, and load-bearing channels, guaranteeing the use of the parts in the right place. This ensures that structures are safe and durable in the long run.
Considering that laser marking does not affect the zinc coating on galvanized steel, these metal parts can be used outdoors without rust developing around the marks.
In addition, laser marking is used to add permanent markings on safety and warning signage.
When it comes to automotive and manufacturing, laser marking is applied to component surfaces, chassis parts, structural pieces, and brackets.
They are marked for regulatory reasons and recall tracking.
Also, brands use laser marking to create logos and identifier signs in manufacturing.
