Comparison of materials for QR code support
| Material | Code Rendering (Contrast) | Resistance & Usage |
|---|---|---|
| 316L (Marine Grade) or 304 Stainless Steel | Black on stainless steel grey (matte / glossy) |
Extreme. Resistant to corrosion, acids, saline atmospheres and food environments. The sustainable industry standard. |
| Anodized Aluminum | Color on aluminum gray | High resistance. The best optical contrast for shower heads. Very good scratch resistance. |
| Bi-layer plastic (Gravoply) | Heart color on surface |
Medium to high resistance. Economical and electrically insulating solution. Ideal for identifying indoor assets, with the option of high-strength, bi-layer plastic material for industrial environments. |
| PMMA (Plexiglas) | All colors available, printed on the back | Very aesthetically pleasing. Suitable for signage or printed back panel (window decal). |

Certifications and Quality Control (ISO & DPM)
Since 1997, we have subjected our manufacturing processes to strict standards to meet the requirements of specific sectors.
- NF EN 9132: marking standard in the aeronautical sector.
- ISO/IEC 29158 (AIM-DPM): standard for reading codes engraved directly onto the material.
- ISO/IEC 15416: standard for linear (1D) barcodes on labels.
