Outdoor signage is an investment in your business’s visibility and first impression. From store facades to informational markers, the materials you choose will determine how your sign performs against weather, time, and city life. Let’s dive into the top contenders—especially the standout—and why your choice matters.
Why Does Metal Matter for Outdoor Signs?

Metals are highly favored for signage because they offer:
- Durability and weather resistance
- A professional, polished visual finish
- Versatility in custom fabrication
- Little to no maintenance
- Strong resistance to vandalism and UV exposure
But not every metal is created equal. Here are the top metals commonly used, and why one consistently leads the pack.
Top Metals for Outdoor Signs
1. Aluminum — The #1 Choice
Aluminum is the industry’s go-to for outdoor signs, and for good reason. It’s lightweight, making installation simple and reducing wear on building facades. Aluminum’s real advantage, though, is its rust-proof nature and resistance to weather extremes, from hot sun to heavy rain.
Key benefits include:
- Will not rust, unlike iron or untreated steel
- Can be powder-coated or painted any color
- Suitable for coastal, urban, and rural environments
- Easy to cut, shape, and customize
- Low maintenance—just occasional cleaning
- Affordable for most commercial budgets
This is why most NYC exterior business signs are fabricated in aluminum.
2. Stainless Steel
Stainless steel comes next when strength and an upscale look are priorities. It’s heavier than aluminum but brings high resistance to corrosion and physical impacts. It’s ideal for humid or salty environments and lends a sleek, modern appearance.
- Withstands moisture and harsh environments
- Excellent for luxe or high-traffic locations
- May cost more and install with more effort than aluminum
3. Bronze & Brass
Bronze and brass shine where elegance and tradition matter—think historic buildings or high-end establishments. These materials develop a patina over time, which can add character but may require more care.
4. Other Metals
- Corten Steel (weathering steel) develops a rugged, industrial rusted finish intentionally.
- Coated Steel can be durable but requires finishes to resist rust.
Choosing the Right Metal for Your Location
Three quick tips:
- Environment: Coastal and very rainy locations should opt for aluminum or stainless steel.
- Budget: Aluminum typically gives the best mix of durability and cost.
- Customization Needs: Both aluminum and stainless steel support a wide range of graphics, colors, and shapes.
