Although visually they may seem similar, their composition and behavior over time make a difference.
🔩 304 Stainless Steel
It is the most commonly used in standard exterior signage.
✔ Good corrosion resistance
✔ Excellent polished or brushed finish
✔ Ideal for normal urban environments
It is an optimal choice for commercial facades in the city, shopping centres and protected interior/exterior projects.
🌊 316 Stainless Steel
It contains molybdenum, which gives it superior resistance to aggressive environments.
✔ Increased resistance to salt corrosion
✔ Recommended for coastal areas
✔ Ideal for industrial or high-humidity environments
In projects near the sea or with high environmental exposure, 316 guarantees greater long-term durability.
🎯 Which one do we recommend?
The choice should not be based only on cost, but on the environment where the sign will be installed.
At A1 Publicidad and Don Letra we analyse each project to advise our professional clients and guarantee the best technical and aesthetic solution.
Because in signage, the difference is often in what you can't see
