Your outdoor signage is more than a wayfinding sign to direct traffic into your door; it represents your brand’s personality, values and professionalism long before they walk through the door. But when your sign is exposed to sun, wind and rain, getting the right material matters.
Aluminum vs Acrylic Signs: Which One Is Best for You? Two of our most popular sign choices are aluminum and acrylic signs — both offering unique qualities in terms of aesthetics, longevity, and maintenance. But which one really has the more lasting power for use outdoors?
In this comparison, we’ll cover the 7 major differences between aluminum and acrylic signs — including practical elements such as weather-proofing, price, and mounting. By the end, you’ll have a clear sense of which material is best for your site, design goals and budget.
Outdoor conditions push any sign to the max—especially in areas with extreme heat, cold or humidity.
Aluminum signs are known for their lightweight durable nature. The metal is naturally rustproof and won’t warp, peel or crack in temperature extremes. Its coating layer further protects the aluminum from damaging UV rays and helps keep text pure, clear, and legible over time even in extreme weather conditions.
Acrylic signs, however durable, are not quite as weatherproof. Acrylic is a stiff thermoplastic that does not yellow or fade, but over time UV light and temperature variations can lead to brittleness or tiny cracks.
Key durability insights:
The bottom line: For year-round outdoor use,aluminum is the tough(est) and longer-lasting choice.
Visual appeal of a sign can help create your brand image and, in this aspect acrylic signs take the lead.
Acrylic has the appearance of glass, and provides a clear, polished surface that complements colors as well adds an element of sophistication. It’s ideal for contemporary-looking brands that aim to deliver a shiny, high-end appearance.
By contrast, aluminum provides a neat matte or brushed look that speaks of professionalism and permanence. It’s widely used for architectural signage, corporate head offices and wayfinding systems.

Longevity isn’t just about how long a sign will last — it’s also about the ease with which you can keep a sign looking great.
Aluminium signs are very easy maintenance. They are anti-rust, never get stains and fade.If it is dirty, simply wipe with a soft cloth and mild soap followed by rinse under cold water to clean the rack. I like them because they are coated for protection so they're perfect to leave outdoors unattended.
Acrylic signs require a bit more work, on the other hand. They can become dusty, fingerprinted and scratchy due to their polished surface. And although they do wipe clean with a microfiber cloth and non-abrasive cleaner, abrasive force can dull the finish and aggressive chemicals should be avoided.

Not only the installation but also outdoor for security and exterior performance, the physical attributes of your sign matter.
Acrylic signs are light weight and easy to hang. But because they are relatively stiff, they risk cracking or chipping if not installed properly. Acrylic blocks in particular require to be fitted with support systems that accommodate thermal movement and the resultant stress fractures.
Aluminum is a bit heavier, yet much more bendable and impact-proof. They cannot be broken by wind, vibration and public handling. Mounting options also include posts, standoffs, or wall mounts that can provide a strong and secure solution in virtually any location.

Tip: Never skip professional installation on long-term signs. Correct installation prevents the warping, leaking and safety hazard.
Price is not irrelevant but it is rather the ratio of performance you get for the price which should be considered as value.
Acrylic signs are typically cheaper up front. They offer a luxurious appearance but do not carry the expensive price tag of glass or metal, so is it no wonder that these planters are becoming increasingly common in businesses aiming to add style without breaking the bank?
Aluminum Signs, while costing more upfront, are a perfect solution long term because of their longevity and little to no maintenance. Aluminum is often less expensive over the long run (over 10 or more years) because it is not replaced as frequently.
Cost and value comparison:
Aluminum signs and Acrylic signs both provide outstanding quality while achieving similar affects with different strengths.
If durability, weather resistance and low maintenance are your top concerns, choose aluminum. It is resistant to the sun, rain and time with little care and offers durability for any outdoor installation.
On the other hand, if you are into contemporary design, popping colors and a glossy finish, then an acrylic sign is far more visually appealing plus better suited for semi-outdoor or sheltered areas that don’t have so much outdoor exposure.
But the better choice depends on where your business is located, its brand personality and budget. The most innovative and effective outdoor signs use a combination of the two materials — aluminum for hardiness and acrylic for decorative, or lighted, elements.
