Top 9 Durable Materials for Outdoor Signs

October 10, 2024 Business Signs

Did you know that 76% of consumers enter a store they’ve never visited before based solely on its signs? This statistic highlights just how crucial outdoor signs are for businesses.

High-quality outdoor signs do more than just catch the eye. They create a professional image for your business, increase foot traffic, and improve the overall customer experience. On the flip side, poor signage can lead to missed opportunities and lost sales as people walk past the store without noticing it.

Given how important outdoor signs are, choosing the right material is a big decision – you’ll want something that looks great, lasts a long time, and fits your budget. Let’s get to it!

Best outdoor sign materials

We’re going to explore top choices for outdoor sign material, from classic options like aluminum and wood to modern alternatives like Dibond and Coroplast. We’ll look at what makes each material stand out, how well it holds up outdoors, and what kind of signs it works best for. 

1. Aluminum

Aluminum is a top pick for outdoor signs, and for good reason. It’s tough, light, and doesn’t rust – a winning combo for signs that need to brave the elements.

Being lightweight means it’s easy to handle and put up, saving you time and hassle during installation. Secondly, aluminum strikes a nice balance between cost and durability. It’s not the cheapest option out there, but it won’t break the bank either. Plus, its long lifespan means you won’t be shelling out for replacements anytime soon.

Want to get creative? Aluminum’s got you covered. You can jazz it up with different finishes, colors, and graphics to match your brand perfectly.

2. Bronze

Bronze has been used for centuries for outdoor signage because this classic metal is built to last.

First off, bronze stands strong against rust and weathering, making it a great option for long-term outdoor use. Rain or shine, coastal breeze or city smog, bronze plaques can take it all in stride. As time goes by, bronze develops what’s called a patina, changing color slightly and taking on a rich, distinguished look. 

If you are worried about it looking too old-school, don’t. Bronze is surprisingly versatile. You can go for a polished shine, a brushed finish, or an antique look. And when it comes to engraving, bronze is hard to beat. It’s perfect for those detailed historical markers or fancy business signs.

On the flip side, bronze can cost more upfront. But think of it as an investment. This material is in it for the long haul, needing little TLC along the way. So while you might spend more now, you’ll save on replacements and touch-ups down the road.

3. Stainless steel

With a modern and professional look, stainless steel is strong, sleek, and ready to take on tough environments. It’s the best material to resist corrosion, even in harsh conditions. Got a beachfront business? No problem. There are special types of stainless steel, like alloy 316, that can handle salty sea air with ease.

Stainless steel brings a modern, high-end vibe to any sign. It’s the kind of material that makes people stop and take notice. Plus, it’s low maintenance. A quick wipe-down now and then is all it needs to keep looking sharp.

Last but not least, stainless steel is pretty flexible when it comes to design. You can get different finishes, such as shiny and polished or more subdued and brushed. And there are various ways to shape and style it, so your sign can be as unique as your business.

4. Acrylic

Acrylic has a crystal-clear appearance that makes it look like your sign is floating on air. It comes in various colors and finishes, with the most popular options being frosted and backlit LED lighting in neon colors. By itself, though, acrylic can be slightly fragile for outdoor use. We recommend using painted acrylic letters instead for longer-lasting outdoor signage.

A big plus is that acrylic is extremely light. You can create big, bold signs without worrying about them being too heavy to hang. It also has built-in UV protection, so it resists yellowing and keeps its clarity year after year.

Cleaning acrylic is fairly simple. A little soap and water, and it’s good as new. No special cleaners or complicated care routines are needed.

5. Vinyl

Vinyl is all about flexibility, both in how it looks and where you can use it. It can stick to pretty much anything – metal, plastic, glass, you name it. This makes it super versatile for all kinds of outdoor signs.

Now, you might be wondering, “But can it handle the outdoors?” Absolutely. Vinyl’s tougher than it looks. It can take on sun, rain, and even snow without breaking a sweat. It’s especially good at shrugging off the harsh UV rays that make other materials fade.

The best advantage of vinyl is, it’s budget-friendly. The material is perfect for those temporary promotions or when you need to switch up your message often. Installing vinyl does not require heavy lifting or complicated tools. Just peel and stick, and you’re good to go.

Plus, the design possibilities are endless. From sparkly letters to photo-realistic images, vinyl is a blank canvas where the only limit is your imagination.

6. 3D Plastic Letters

3D plastic letters bring a dynamic element to outdoor signage. Crafted from high-quality plastics like acrylic or PVC, these dimensional characters offer both visual appeal and practicality.

These letters boast impressive weather resistance, standing up to UV rays and various outdoor conditions. Their three-dimensional nature creates depth and shadow, enhancing visibility and brand impact.

Customization is their key strength. Available in a wide array of colors, sizes, and fonts, 3D plastic letters allow for precise matching to brand aesthetics. Some options even incorporate LED lighting for enhanced visibility in low-light conditions.

Compared to metal alternatives, 3D plastic letters often come at a more accessible price point. Their lightweight nature simplifies installation, reducing structural requirements and labor costs.

7. Wood

There’s something about a wooden sign that just feels right. It’s got that natural, rustic charm that can make your business stand out in a sea of plastic and metal.

Let’s start with the obvious: wood looks good. It’s got a warmth and character that other materials just can’t match. If you’re going for that cozy, artisanal vibe, wood is your best bet.

But here’s the thing about wood – unlike some other materials, wood requires some prep work to stand up to the elements. You’ll need to seal it properly to keep moisture out and prevent warping or rotting.

Also, wood can be a bit of a mixed bag cost-wise. Some types are pretty affordable, while others (like high-end hardwoods) can be pricey. And don’t forget to factor in those maintenance costs over time.

8. Dibond

Dibond combines strength and style in outdoor signage. This aluminum composite material features two thin metal sheets with a polyethylene core, creating a durable yet lightweight option.

Its resistance to corrosion and UV rays ensures longevity in various climates. Dibond maintains its shape well, avoiding warping or delamination over time.

The smooth surface is ideal for high-quality printing, making it suitable for storefronts, directional signs, and branding panels. While not the most economical choice, Dibond offers good value considering its durability.

9. Alumalite

Alumalite’s structure consists of aluminum sheets sandwiching a corrugated plastic core, providing rigidity without excess weight. As a result, this material excels in outdoor settings, resisting weather effects and temperature fluctuations.

Its flat surface allows for crisp, detailed graphics, making it popular for large-scale displays like billboards and construction site signage.

Compared to similar options, Alumalite provides comparable durability often at a competitive price point. Its lightweight nature simplifies installation, even for expansive signs.

Maintaining Alumalite is uncomplicated – periodic cleaning with gentle soap suffices. Like its counterparts, the aluminum elements can be recycled, contributing to sustainable practices.

Types of outdoor signs

Now we’ve looked at the materials available for outdoor signs, let’s explore the different types of  signs you might encounter. Each type serves a unique purpose and works best in specific situations.

Panel signs 

Panel signs are flat, sturdy boards that businesses often use for storefronts or to guide people around. They’re great because they can handle tough weather and look professional. While they cost more upfront and require proper installation, they’re a solid choice for long-term use.

Illuminated signs

As the name suggests, these are signs that light up. You’ll often see them on restaurants, hotels, or shops that stay open late. They grab attention, especially when it’s dark out. The downside? They need electricity to work and might need more upkeep than non-lit signs.

Channel letter signs

Picture those big, 3D letters you see on buildings. That’s what we’re talking about here. Channel letters make a bold statement and can be shaped into almost any design. They look impressive but keep in mind they’re usually pricier and trickier to install than panel signs.

Temporary signs

Need to advertise a quick sale or event? Temporary signs are your go-to. They’re cheap and easy to put up and take down. The trade-off is that they won’t last long in harsh weather.

A quick note about installation: no matter which type of sign you choose, how you put it up matters a lot. Good installation helps your sign last longer and stay safe. It’s not just about looking good – it’s about making sure your sign can handle wind, rain, and whatever else comes its way.

At Impact Signs, we offer expert installation for all types of outdoor signs, right across the US. We make sure your sign is set up right so it stays visible and durable for years to come.

Factors to consider while choosing outdoor signage material

Picking the right material for your outdoor sign isn’t just about looks. There are several key factors you need to think about to make sure your sign does its job well and lasts a long time. Let’s break these down:

  • Durability: Choose a material based on how long the sign needs to last—short-term event or permanent storefront—since different materials have varying lifespans.
  • Weather resistance: Ensure the material can withstand your local climate’s challenges, such as rain, heat, or snow, without fading, warping, or deteriorating.
  • Cost: Balance upfront costs with long-term value; cheaper materials may need frequent replacement, while high-end options might not be necessary for temporary signage.
  • Maintenance: Consider how much upkeep the material requires—some need regular care, while others are low-maintenance and stay in good condition with little effort.
  • Environmental impact: Opt for eco-friendly materials that are recyclable or sustainably produced, benefiting both the environment and your brand’s image.
