Aluminum Composite Material (ACM)

Low-cost ACM offers good dimensional stability and a metallic look, at half the weight of aluminum

Aluminum composite material (ACM) is a three-layer sandwich panel consisting of two pre-painted aluminum sheets bonded to a polyethylene (PE) core. ACM panels are an excellent material for indoor or outdoor applications that require good dimensional stability, low weight, and a sleek, brilliant look.

Eye-catching, durable, and only half the weight of aluminum, ACM metal panels are both attractive and practical for use in visual merchandising, framing, archiving, commercial interiors and exteriors, construction, and fine art applications.

Adventurous designs demand ACM for its aesthetic qualities combined with rigidity and ease of fabrication. DIBOND® aluminum composite panels are available in a wide range of color combinations, surface finishes, and thicknesses, and are suitable for printing or graphic mounting. Designers and engineers often substitute ACM panels for aluminum sheets or wood in interior and exterior signage, structural signage, architectural cladding, point-of-purchase (POP) displays, exhibits, and kiosks.

Industrial engineers also find ACM advantageous for OEM applications such as engine covers and housing.

Aluminum Composite Material (ACM) Options

DIBOND® — A longtime industry standard, DIBOND® comprises two pre-painted aluminum sheets (0.012 in thick each) sandwiching a solid polyethylene core. It is the flattest panel on the market, approximately one-half the weight of a solid aluminum sheet, durable for outdoor applications, and well suited for digital and screen-printed graphics. It can be routed and returned to add dimension, or roll-formed to create sweeping curves. Fabrication options also include cold mounting graphics, repositioning vinyl, painting, saw cutting, routing, and die cutting/punching. DIBOND® aluminum panel will not bow or experience “oil can” wrinkling.

DIBOND® is also available with a specialty mirror finish offering outstanding reflective properties similar to those of a conventional glass mirror, without the breakability of glass and at about half the weight. The mirror surfaces can be both screen and digitally printed as well as laser engraved.

DIBOND® exhibits long-term application life in exhibits and kiosks; standard or archival framing; and interior, exterior, and structural signage.

Fire rating: DIBOND® is Underwriters Laboratories® Inc. recognized for UL 94V-0 and is a UL-recognized component for electrical signage. All thicknesses meet the criteria for ASTM E-84 and are Class 1 or Class A materials.

E-PANEL™ — The aluminum facers in the E-PANEL™ material are slightly thinner, at 0.008 in, than those in DIBOND®. It is recommended for flat-panel applications only. It is suitable for cold mounting graphics, repositioning vinyl, both digital and screen printing, and painting. It can be saw cut, routed, or die cut/punched.

E-PANEL™ exhibits long-term application life in POP displays, exhibits and kiosks, standard or archival framing, and interior and exterior signage.

EPL-5™ — The aluminum facers are 0.005 in thick on EPL-5™, which is recommended for flat-sheet applications only. It is suitable for graphic mounting, repositioning vinyl, and both digital and screen printing. It can be saw cut, routed, or die cut/punched.

Like E-PANEL™, EPL-5™ exhibits long-term application life in POP displays, exhibits and kiosks, standard or archival framing, and interior and exterior signage.

Fire rating: EPL-5™ is not rated.
