Outdoor seasonal programs need panels that hold up to weather swings, handling, and repeated install cycles. Maxmetal® 3mm ACM is the manufacturer substrate Seasonal Metal Signs builds holiday boards on — chosen for published durability advantages versus common alternatives.
Lighter and more durable than MDO or solid aluminum
Maxmetal® states that the product is lighter in weight and more durable than both MDO and solid aluminum panels. For holiday storefront, lobby, and curb-facing programs, that combination supports easier handling while retaining a rigid ACM structure with two .15 mm pre-painted aluminum faces bonded to a solid polyethylene core.
Temperature, water, and surface resistance highlights
From the manufacturer surface and product properties tables:

UL Recognized or Listed is Yes. Digital Substrate remains No for standard 3 mm — finishing methods should follow manufacturer guidance rather than assuming digital-substrate marketing claims.
How Seasonal Metal Signs uses ACM for holiday programs
Stock Maxmetal® sheets are fabricated into finished 24″ × 36″ seasonal boards — a safe max print and cut size cut down from manufacturer sheet sizes (4′ × 8′, 4′ × 10′, and 5′ × 10′ in panel dimensions). Premade holiday art covers the calendar; upload-your-design paths support brand-specific messaging. Retail price is $266.67 per seasonal board.
Production sits under the First Impressions Printing umbrella, with Seasonal Metal Signs as the brand storefront for Maxmetal® holiday SKUs.
