Aluminum Signs
At ShieldCo, aluminum is one of our go-to materials for a reason. It provides strength and long-term resilience while being light weight, making it ideal for both indoor and outdoor signage.
Why We Love Working with Aluminum
We use marine-grade 5052 aluminum, carefully selected for its superior adaptability, corrosion resistance, and ability to hold finishes flawlessly.
5052 marine-grade aluminum resists warping, withstands extreme weather, and offers better finish adhesion than standard commercial grades. It cuts cleanly, forms seamlessly, and provides a perfect canvas for powder coating, brushing, or anodizing.
From office signage to architectural exteriors, aluminum performs exceptionally well in harsh environments, including coastal regions, due to its built-in corrosion resistance. Combined with crisp fabrication and clean aesthetics, and this is a premium material worthy of top brands.


How We Work with Aluminum
We approach every aluminum sign with an artist’s eye and a fabricator’s precision. Using high-powered CNC equipment and fiber lasers, we produce crisp edges, clean cuts, and detailed logos with razor-sharp accuracy. This precision allows us to expertly produce signage from large exterior panels to intricate interior lettering.
Our 3D layering techniques give aluminum signs standout depth and bold visibility, creating natural shadows and layered contrast that flat signs simply can’t replicate. By combining multiple aluminum layers in contrasting finishes such as brushed silver over matte black, we deliver signs with dimension, readability, and huge visual impact.
Does your design need curves, cutouts, beveling, or sharp geometric forms? We do it all. Our team bends, forms, and mounts aluminum with purpose, bringing structure and sophistication to every design.
Finish Options and Customization
Aluminum is a blank canvas that accepts a wide variety of finishes, and we optimize each piece to suit your brand, environment, and application.
Popular finishes include:
- Brushed aluminum for sleek, modern appeal
- Anodized coatings for enhanced corrosion protection
- Powder coating in any color imaginable, perfect for matching company branding
- Polished or matte textures for refined detail or bold contrast
Each finish we apply adds durability while creating rich, high-end visual texture for your lobby, storefront, or exterior wall. Our custom aluminum signs are built to shine, literally and figuratively.

Custom Aluminum Sign FAQs
Metal signs come in various types including aluminum, stainless steel, brass, and copper. Styles range from flat panels and dimensional letters to multi-layered 3D designs. They can be used indoors or outdoors, with finishes like brushed, polished, powder-coated, or painted. Customization options include cutouts, backlighting, and engraving.
Aluminum signs are highly durable and corrosion-resistant. On average, they last 7–10 years outdoors, even longer indoors. With proper care and UV-resistant coatings or finishes, their lifespan can extend up to 15 years or more, making them a smart, long-term investment.
Street signs are typically made from 5052-H38 aluminum or Aluminum Grade 6061, known for their strength, corrosion resistance, and ability to withstand outdoor elements. These grades are ideal for road signage due to their durability, weather resistance, and reflective coating compatibility.
