Thin Metal Plates and Signs

Thin Metal Plates offer unmatched versatility, precision, and durability across a wide range of applications. Crafted from ultra-thin sheets of stainless steel, aluminum, brass, copper, or nickel silver, these signs combine premium materials with custom finishes and imprinting techniques — perfect for wayfinding, identification, branding, and large-volume production.

Each thin-gauge sign is engineered for long-term indoor or outdoor use and backed by our Lifetime Guarantee.

What Are Thin Gauge Metal Signs?

Thin-gauge metal signs are made from high-quality sheet metal ranging from 0.015 inch to 0.125 inch thick. Despite their slim profiles, they deliver exceptional strength, fine detail, and professional appearance.

Available sizes: from 1 inch × 1 inch up to 23 inches × 36 inches (maximum 5.75 sq ft / 828 sq in)
Available thicknesses: eleven options between 0.015 in and 0.125 in

Ideal uses:

• Wayfinding and room identification

• Sequential numbering and data plates

• Branding and product labeling

• High-volume architectural or industrial applications

Corner and Shape Options

Thin-gauge plates can be customized with four standard corner shapes or custom-cut contours upon request. Corners can be rounded or chamfered to fit your design or mounting style.

Fonts, Artwork & Customization

• Custom text, logos, and graphics may be supplied in vector artwork (AI, EPS, PDF, or SVG).

• Text and artwork can be raised or recessed when etched.

• Small type, serial numbers, and intricate designs reproduce accurately due to the precision of the thin-metal process.

Finishes and Imprinting Techniques

Our thin-metal signs can be customized using a range of imprinting methods, each suited to specific aesthetics and environments.

Etched and Color-Filled

Chemical etching creates recessed designs that are filled with durable paint for contrast.
Available in etched and color-filled, etched and frosted, or etched and antiqued finishes.

Sublimated (Full-Color)

Sublimation permanently infuses inks into the metal surface, producing vibrant, photographic images.

• DynaSub™: Interior use only (satin silver or gloss white finish)

• DuraLuxe™: Exterior-grade sublimation — UV-resistant, scratch- and graffiti-proof

Screen Printed

Screen printing applies ink through a fine mesh stencil, one color at a time. This process yields vivid, colorfast, high-resolution graphics ideal for branding or product labeling.

Chemical Etching

Used on stainless steel, brass, and aluminum, this process etches the design into the surface using a photoresist and acid bath, creating a recessed, durable image. After etching, plates are painted, baked, and sealed for longevity.

Installation Environments

Thin-gauge metal signs are suitable for indoor and select outdoor installations depending on the metal type and finish.

Mounting Options

Choose the mounting method that best fits your installation surface.

• Thru-Hole Mount: Two or four holes (1/16″, 1/8″, or 3/16″ diameter). Hardware sold separately.

• Double-Face Tape Mount: 2-mil industrial tape applied to the back. For interior use only.

Sublimation Process Overview

Sublimation is a heat-transfer process where solid ink transforms directly into gas, bonding permanently with the metal coating.
During production:

1. Artwork is printed on sublimation paper.

2. The paper and metal plate are pressed together under heat and pressure.

3. The ink vaporizes and embeds into the coating, creating a durable, full-color image.

This process delivers unmatched image sharpness and fade resistance for both photographic and graphic applications.

Screen Printing Overview

Screen printing transfers ink through a mesh stencil using a squeegee. Each color requires a separate screen, allowing multi-color designs with excellent opacity and consistency.
Screen-printed signs offer bold color, excellent adhesion, and high resolution suitable for identification and branding.

Etching Process Overview

Chemical etching uses a printed resist to protect specific areas of the metal, exposing the rest to acid.
After etching, recessed areas can be paint-filled, antiqued, or left natural, then baked and sealed for a lasting finish.
Etched metal signs provide timeless beauty and durability, especially in stainless steel and brass.
