About Wholesale Aluminum Sign Printing
Aluminum is the premium substrate for permanent and semi-permanent exterior signage. Its smooth, rigid surface accepts UV inks beautifully, producing sharp text, vivid colors, and crisp logos that hold up for years in direct sunlight, rain, and temperature extremes. Unlike coroplast or plastic, aluminum has the polished, professional look that high-end clients expect on architectural signs, compliance signage, and premium retail displays.
We offer aluminum in three thicknesses to match your application. Lightweight .024 aluminum is ideal for car tags and small riders where flexibility is needed. The industry-standard .040 gauge provides excellent rigidity for most sign applications — parking signs, realty signs, ADA panels, and general wayfinding — while keeping weight manageable. Heavy-duty .080 aluminum is the choice for maximum rigidity in large formats or high-wind environments where durability is non-negotiable.
For clients who want the structural rigidity of thick aluminum at a lower price point, ACM (Aluminum Composite Material) is the answer. ACM consists of two sheets of .015 aluminum bonded to a solid polyethylene core, creating a panel that is extremely rigid, lightweight, and perfectly flat — ideal for dimensional letters, cabinet faces, and architectural signage up to 4 by 8 feet. ACM is significantly less expensive than .080 solid aluminum and delivers comparable performance for most applications.
We also produce .024 aluminum car tags using a 4-picoliter dot size, achieving ultra-high resolution prints on pre-punched blanks. Whether you need a single custom tag or a bulk run for an auto dealership client, SignMaster delivers with the same 24-48 hour turnaround and free shipping that applies to every order.
