FAQs
Q: Why is this aluminium sheet suitable for outdoor signage?
A: It features a PVDF coating with exceptional UV resistance and colorfastness, enduring sun, rain, and harsh outdoor conditions. The 25 gauge thickness balances flexibility and stability, ideal for shaping into various sign designs while maintaining durability.
Q: Does the 36-inch width fit common outdoor signage needs?
A: Yes. The 36-inch (914mm) width is a standard size for outdoor signs, supporting single-panel use for small signs or seamless for larger displays. It reduces material waste and simplifies fabrication for most signage projects.
Q: What does ASTM standard guarantee for this product?
A: ASTM compliance ensures consistent quality, including uniform thickness (25 gauge), reliable material composition, and adherence to industry performance standards. It guarantees the sheet meets strict requirements for durability and processability in signage applications.
Q: How long will the pre-painted finish last outdoors?
A: The PVDF pre-painted layer offers long-term color retention and adhesion. Under typical outdoor conditions, it resists fading, peeling, and corrosion for 10–15 years, minimizing the need for repainting or replacement.
Q: Can this sheet be easily cut, bent, or printed for signage?
A: Absolutely. The 25 gauge aluminium is lightweight and highly processable, supporting cutting, bending, and digital printing. It works with common signage fabrication tools, enabling quick customization for logos, text, or graphic displays.
