Dimensional letters & logos
Making your business stand out
Adding dimensional letters and logos to your business adds depth, visibility, and a sense of permanence.
OPA is a regional Gulf South leader in enhancing your brand through custom logo elements.
What is a dimensional letter?
Give your brand depth
A dimensional letter or logo is a non-illuminated, three-dimensional sign made from materials like metal, acrylic, PVC, high density foam or wood. These pieces rely on ambient or directed lighting, using depth, shadow, and finish to create visual impact.
Outdoors, dimensional letters provide a durable option for building signage where lighting may not be needed. Indoors, they are popular in lobbies, reception areas, and retail spaces, where they serve as refined branding features with a polished, architectural feel.

Staying Power
Quality matters
Dimensional letters should do more than look good on installation day. When shortcuts are taken, adhesives fail, and letters shift. What starts clean can quickly become uneven, faded, or loose.
The longevity of signage is determined by its material quality. Lower-grade finishes can fade, peel, or corrode with prolonged exposure to harsh Gulf South environments.
Withstanding Gulf South conditions
At OPA, installation and longevity is part of the build. We rely on mechanical fastenings, not temporary adhesives, to ensure each letter is securely mounted and will hold over time.
We also use automotive-grade clearcoats on painted elements for lasting color and durability, and cast laminates on printed graphics to resist fading and wear.
Paired with strong fabrication and attention to detail, the result is signage that maintains its appearance and integrity for years.
YOUR SPECS
It’s all in the details
OPA fabricates each piece to exact brand standards, with accurate letterforms and consistent color matching across paint and printed elements.
Finish options include gloss, satin, and matte, along with custom textures and a wide array of metal finishes, including antique, mirror and chrome, to suit your needs.
Letters can be produced in thin or thick profiles, flush-mounted for a minimal appearance, or standoff-mounted to add shadow and dimension.

aluminum
Traditional channel letters use illuminated acrylic faces to project bright, highly legible light outward. This style offers maximum visibility and is ideal for storefronts, retail centers, and roadside signage. Also called front-lit.
-
![]()
ACRYLIC
Also known as reverse-lit letters, halo-lit channel letters project light behind the letterforms, creating a soft glow on the wall surface. This approach produces a refined architectural effect and emphasizes depth and dimension.
-
![]()
PVC
Chunky, playful letters made from thick acrylic for full-bodied light. Used primarily in modern shopping and dining districts, this is a fresh approach to lighted signage.
-

SPECIALTY METAL
Open-face channel letters expose the lighting element itself often neon, led tubing or marquee bulbs. This style is especially popular for restaurants, bars, and entertainment districts.
-

HIGH DENSITY FOAM
Crisp outlines of light are created using concealed LEDs that illuminate the edges of acrylic or translucent materials. Often used for contemporary architectural signage where a refined glow and sharp letter definition are desired. Also called side-lit.
FINISH

MIRROR, CHROME & METAL
Highly polished metal faces create a reflective surface that interacts with surrounding light and architecture. Mirror finishes are often used in hospitality, retail, and contemporary storefronts.

PAINTED
Custom painted aluminum letters ensure color accuracy with brand standards. Automotive-grade coatings provide long-term durability and resistance to fading, corrosion, and weather.
Face Lit lettering Options

![]()
Traditional
A time-tested construction method using colored acrylic faces framed by plastric trim caps. This approach provides clean edges and strong nighttime brightness and is often used in shopping centers and high-traffic districts.
-
![]()
Trimmless
Trimless letters eliminate the traditional trim cap, creating a smoother and more contemporary appearance with acrylic that runs to the edge of the letter face.
-
![]()
Fabricated
Acrylic letter faces can be framed with custom cut and fabricated metal trim for a sleek, modern look. Often metallic or mirrored, these are commonly found in high-end shopping and pedestrian districts.
-
![]()
BEVEL
Fabricated edges with jewelry-like beveling for added play of light and character. Used for refined applications where details matter, such as high-end dining and retail.
-
![]()
Printed
High-resolution backlit prints of photos or branded patterns can be applied to faces of channel letters for a unique, custom effect. Often suited for interiors where details can be appreciated, but resilient enough for outdoor use.
LAYERING
Color-changing
Optional RGB LED illumination can shift colors dynamically, giving businesses the flexibility to match branding, highlight promotions, or create eye-catching nighttime effects. Programmable lighting adds energy, visibility, and modern impact to traditional channel letter signage.
Day/night transitional
Day/night transitional acrylic and perforated vinyl allow channel letter faces to display true brand colors during the day while illuminating brightly after sunset. This technique also improves contrast by day on light-colored storefronts, ensuring signage remains bold, legible, and visually consistent 24 hours.
Installation methods
Flush-mounted
Custom-fabricated raceways provide a clean, secure mounting solution for channel letter signage, especially in high traffic areas where service access matters. Raceway installations reduce the number of electrical penetrations through the building and are often required by landlords or property managers.
OPA can fabricate raceways to precise client specifications and finish them to match your building, allowing the structure to blend seamlessly into architecture while protecting electrical components.
Backing panels
OPA can custom-fabricate channel letter backing panels in virtually any shape or size, allowing signage to align with brand elements or adapt to complex architectural features.
These backers can be painted, digitally printed, or enhanced with additional design elements such as complementary neon or LED piping, turning a simple letterset into a more dynamic storefront feature.
Standoff-mounted
Direct-to-facade channel letter mounting creates a clean, architectural look by allowing each letter to appear individually integrated into the building surface.
This approach requires careful pre-planning, as every letter needs its own electrical pass-through into the façade. When executed properly, it delivers a refined installation with minimal visible hardware and maximum visual impact.
Awnings & rail-mounted
Channel letters can also be mounted vertically to custom-fabricated rails or installed downward into awnings, creating the illusion that the letters stand above the structure or roofline.
This bold approach adds height, visibility, and dimension while integrating signage into architectural features for a bold, elevated storefront presence.
UL LISTED
OPA Signs & Graphics is a UL Listed sign manufacturer, meaning our illuminated signage is fabricated in accordance with rigorous safety and electrical standards verified by Underwriters Laboratories.
This certification ensures our channel letters and electrical components meet nationally recognized safety requirements, helping streamline permitting, satisfy landlord and municipal codes, and ensure reliable long-term performance.
put IT ON AN AWNING
Turn your storefront into a landmark
Channel letters are often the centerpiece of a storefront, but pairing them with a custom fabricated awning can transform simple signage into a complete architectural statement. OPA designs awnings specifically to support and frame illuminated letters and logos, creating a cohesive storefront.
By designing awnings and channel letters together, we account for structural support, wind loads, attachment points, and electrical routing from the beginning.
This integrated approach results in cleaner installations, concealed wiring, and a more durable, code-compliant system.
