Selecting the right material for an engraved sign can be critical – not only for durability, but also for readability, safety, and a professional appearance. At Knutwall, we help customers every day from sectors such as electrical installation, construction, industry, and automation to choose the right signage solution based on environment, function, and technical requirements.
In this post, we’ll guide you through the most common materials for engraved signs and what to consider when making your choice.
Engraved plastic signs (often made of acrylic) are a popular option thanks to their low weight, durability, and cost-effectiveness. They are halogen-free and UV-resistant, making them suitable for both indoor and outdoor use – such as in technical rooms, electrical panels, or building systems.
Advantages:
✔️ UV- and weather-resistant
✔️ Available in various colors and thicknesses
✔️ Easy to mount with tape, adhesive, or screws
Perfect for electrical installations, facility labeling, and marking of control systems.
In exposed or demanding environments – such as industrial plants, offshore facilities, ventilation systems, or food production – engraved signs in stainless steel are essential. They are extremely durable and resistant to chemicals, moisture, UV light, and dirt.
Advantages:
✔️ Extremely long lifespan
✔️ Clear and permanent laser engraving
✔️ Ideal for environments requiring high hygiene and durability
Commonly used in production lines, industrial machinery, water systems, and outdoor environments.
Aluminum signs combine durability with a visually appealing look. At Knutwall, we offer full-color printed aluminum signs – perfect for including logos, product numbers, or clear symbols. These signs are suitable for use on electrical cabinets and in production areas.
Advantages:
✔️ Lightweight and highly stable
✔️ Sleek brushed silver surface
✔️ UV-laminated for outdoor durability
An excellent choice for brand-conscious environments where appearance matters.
