3mm Maxmetal means the panel is approximately 3 millimeters thick from face to back. It is the most common specification for custom business signage because it delivers a strong balance of:
- Print quality
- Structural stability
- Outdoor lifespan
- Cost control
In most FIP Printing projects, 3mm is the default recommendation for year-round promotional use. It is rigid enough for clean presentation, but still manageable for mounting, transport, and quantity orders.
If your placement is high wind or oversized, you may need a heavier profile. For standard campaign and storefront use, 3mm usually covers the requirement.
