Chemical or ‘photo’ etching is a manufacturing process that permanently removes text or characters into a surface with depths ranging from 0.1mm to 0.5mm.
Many industries use this method to create intricate designs and parts: the text can either be indented or protruding above a material’s surface, and is normally filled with paint to ensure it can be easily read. Multiple colours can be used to produce a professionally branded aesthetic finished product.

Chemical etching has been around since the 1960’s. The process creates components that pass quality control seamlessly enabling AQUASIGN to manufacture customised oilfield signage in short lead times. Chemical etching is one of our most popular manufacturing methods as it complements the oil and gas industry’s requirement for permanent, high accuracy, reliable signage.

Examples of Chemically Etched Oilfield Signs
Chemically etched metal plates are suitable for the harsh offshore environment providing fit for purpose solutions for certification or nameplates. Most commonly used topside, these signs don’t require anti-fouling technology, but what they do require is an accurate finish to convey clarity on information such as:
- The equipment type and number
- Manufacturer batch and traceability numbers
- Critical positions: open or closed
- The date the equipment was last tested
- Company logo’s
- Contact details

The Benefits of Chemically Etched Signage
Metal integrity: chemical etching has the advantage over other methods such as stamping or punching of leaving the internal structure of the metal unchanged. The material’s hardness, grain structure, or ductility of the metal is not compromised. This creates an exacting manufacturing standard every time and creates reliable, fit for purpose signs for offshore environments.
Metal Compatibility: silver, stainless steel, copper, brass, aluminium…chemical etching will etch perfectly on these metals.
High accuracy doesn’t come at a price: A nameplate can be simple or complex in design regardless of the information contained, the process is the same so too is the cost.
Read our blog where we talk about why signage is so important for health and safety policies offshore.
Fast turnaround: designs are confirmed digitally and applied using a vacuum, removing room for errors. The entire process is relatively fast, flattering the tight deadlines offshore companies often work within.
Professional aesthetic: company logos in colour, part numbers or other identifying marks can easily be etched into the surface during manufacture at no extra cost.Chemical etching providespermanent marking on metal even in the harshest offshore environments: the coloured paint may be removed after many years however the information on the plate would still be readable.
Easy to install – chemical etched plates can be attached to surfaces in a variety of ways. For a mechanical fix, precision cut bolt holes can be added during manufacture. Another option is an offshore approved adhesive – Biohesive®225 – which can bond and seal many materials to a wide range of .

Chemical etching is becoming more and more popular because of the above benefits. The oilfield signage section of our website provides an overview of a few manufacturing methods commonly used in oil and gas, but if chemical etching is suited to your project needs, why not contact us today?
Numerous amounts of designs can be manufactured from one sheet of metal during the chemical etching process: It’s an economical choice for creating accurate signage for offshore companies and fosters better asset tracking and traceability.
