Industrial Chemical Etching Services

Most popular to create metal nameplates for harsh environments, our chemical etching process creates eye-catching and durable permanent markings into various metals. Carefully completed under controlled conditions, the chemicals corrode precise patterns, shapes and words into a selection of materials including stainless steel. Once the surfaces have been chemically etched to the desired depth, they can be left as is or filled with paint for a vibrant finish.

Chemical Etching

At Icon Engraving, we specialise in the precise and detailed art of chemical etching, a process ideal for crafting durable and long-lasting markings on a variety of metals. Our expertise lies in transforming stainless steel, brass, copper, and aluminium into intricately detailed nameplates and signage, perfect for enduring harsh environmental conditions or weather.

Our chemical etching services include industrial signage, labelling, identification tags, and more, all designed to withstand demanding industrial environments. Beyond industrial applications, we can chemically etch metals to create elegant commemorative plaques and memorial plaques, perfect for honouring significant events, locations and individuals.

After achieving the desired depth, we offer a wide selection of vibrant paint fills, adding both visual appeal and enhanced durability to your industrial signage. Whether you are looking for a small collection of units for a specific space or a mass production order to cover an entire work site, get in touch with Icon today to find out how we can help.


Industrial Chemical Etching

How durable is chemical etching in extreme conditions?

Chemical etching is exceptionally durable in extreme conditions, which is why it is a preferred choice for applications that require longevity and resistance to weather exposure when outside or in harsh environments inside.

Starting with the material used, typically stainless steel or brass, are both highly resistant to corrosion. Chemical etching does not compromise the resistant properties of the material’s surface ensuring longevity of your designs. This also makes chemically etched surfaces water, temperature and weather-resistant, as the designs are now a part of the material.

To make chemically etched metal signage even more resistant and the colours more vibrant you can choose to paint-fill. This adds an extra layer of protection that is especially impervious to chemicals or UV radiation.

What metals can be etched using this chemical process?

At Icon Engraving we chemical etch metals that are valued for their durability, strength, and resistance to harsh conditions. The most commonly etched metals for industrial purposes include:

Stainless Steel: Highly resistant to corrosion and temperature extremes, it’s used in everything from machinery components to industrial signage.

Aluminium: Favored for its lightweight nature and resistance to corrosion, aluminium is used in aerospace, automotive, and manufacturing industries.

Brass: Known for its machinability and corrosion resistance, brass is often used in industrial machinery, electrical components, and decorative elements in industrial settings.

Copper: Essential in electrical components due to its excellent conductivity, copper is also used in plumbing, heating, and cooling systems.

Can chemically etched areas be coloured or paint-filled?

Yes, chemically etched areas can be coloured or paint-filled. A popular choice for making signage more visible and/or adding contrast, paint fills can also increase the resistance of the material to corrosion in environments with chemicals or high-UV exposure.

How does the paint-filling process of chemical etching work?

After the chemical etching process is complete, the recessed areas created by the etching can be filled with coloured paints or inks. This is done by applying the paint over the entire surface of the material and then wiping the excess off. This leaves the painting only in the etched areas and ensures an even fill and finish.

If more than one paint colour is to be added to the chemically etched material, sections may be covered and painted individually to prevent any crossover or mixing in painted areas.

Once the areas are paint-filled and the paint has dried, we carefully clean the surfaces and complete a final quality check before arranging delivery or collection.

What is Icon Engravings' capacity for chemical etching orders?

Icon Engraving is fully equipped to fulfil a diverse range of chemical etching orders. We have the capability and capacity to handle everything from small-batch orders on a limited run to large-scale mass production for entire work sites. This is also true for our additional etching services such as paint filling, a common add-on that we provide to enhance the visibility and aesthetic appeal of the etched areas and provide an added dimension of customisation. Whether it’s a small, personalised project or a large industrial order, we are committed to meeting our clients’ specific needs with flexibility and excellence.


What is the difference between etching and engraving?

Chemical etching and engraving are distinct methods for marking metal surfaces, each with different processes and end results. Chemical etching, also known as photochemical etching or chemical milling, employs a controlled chemical reaction to remove metal. This technique, starting with a CAD drawing, uses a mask to etch precise, intricate designs, especially on thin metal sheets. It’s less stressful on the material, preserving its original properties, making it ideal for industrial signage in harsh environments due to its durability and longevity.

Engraving, however, is a physical process that removes material by cutting or carving into the metal, often with lasers or tools. More suited for thicker materials, engraving is apt for deep cuts and grooves but can alter the metal’s structural integrity.

While etching focuses on metals, engraving is versatile, used on plastics, woods, leather, and acrylics, suitable for cable tags, general industrial signage, and defense asset tagging. At Icon Engraving we also offer Industrial Laser Engraving Services.





Request Chemical Etching Quote

Contact the Icon Engraving team with details of your chemical etching requirement including the type of metal, dimensions, thickness, quantity of final pieces, and any specific patterns or designs.

Chemical Etching Process

Upon receiving the order your chosen material will be procured and prepared for the chemical etching process. If you have opted for paint-filling, this stage will come after the chemical etching and involves multiple stages depending on the number of colours.

Pick-Up or Request Delivery

Finally, after the chemical etching and paint filler are complete, our team will check each unit thoroughly as part of our final quality check. Once complete we will notify you that your order is ready, for you to either pick up from our Winnellie depot or arrange delivery.
