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.
