Case Study: Backlit Aluminum Exterior Signs and a Full Interior Sign Package for DC BLOX in North Augusta

When DC BLOX built its new data center at 11144 Atomic Road in North Augusta, South Carolina, they needed signage that could do two very different jobs. Outside, the building had to be easy to identify from across a large site, day or night. Inside, staff, contractors, and visitors needed clear, code-compliant signs to move through offices, secured corridors, and technical spaces. Optic Signs handled both: two halo-lit aluminum logo signs on the building, address and lettering signs on the exterior, and a full interior package of 26 ADA room identification and wayfinding signs. The result is a facility that carries the DC BLOX brand from the parking lot to the data hall door.

The Project at a Glance

• Client: DC BLOX, North Augusta, SC
• Building type: Data center with a metal panel exterior
• Primary exterior signs: Two halo-lit aluminum logo and wordmark signs, one on the north elevation and one on the west elevation
• Overall sign size: About 16'-10" wide, with a 50" tall logo mark and 36" tall letters

The Exterior: Halo-Lit Aluminum Logo Signs

Large commercial and industrial buildings have a branding challenge. The walls are big, the colors are neutral, and the building is often seen from a long way off. A small or flat sign gets lost. That's why each of the two main signs on the DC BLOX building is built at real scale: a 50" tall logo mark and 36" tall letters that span almost 17 feet.

Every piece is fabricated from aluminum, 2" deep, and painted with satin finishes matched to the DC BLOX brand guide. The logo mark's stacked blocks are painted in a satin red and a satin purple, and the "DC BLOX" wordmark is finished in a dark satin gray that stands out sharply against the light metal panels. The purple ties into the purple accent panels on the building itself, so the sign and the architecture look like they were designed together.

Then there's the lighting. With halo lighting (also called reverse-lit or backlit lettering), the LEDs sit inside each letter and aim back toward the wall. The letters stand 1-1/2" off the facade, so the light spreads out behind them and outlines every character. That means the signs work around the clock:

• In daylight, the dark letters and bold logo colors read crisp and dimensional against the building.
• At night, the halo outlines the logo and wordmark, so the building stays identifiable and looks sharp after dark.

Putting a matching sign on two elevations means the building is branded from more than one approach, whether visitors are coming in from the road or across the site.

Address Signs That Help People Find the Building

On a large site, a logo alone isn't enough. Delivery drivers, contractors, and emergency responders need to find the right building and the right door quickly. We added three more exterior elements to handle that:

• Dimensional address numbers. The "11144" numbers are 8" tall, pan-formed from 1/8" aluminum, 3" deep, and painted to match the brand gray. They sit right below the wordmark, so the brand and the address read together.
• Non-illuminated building lettering. A 36" tall set of fabricated aluminum letters, flush-mounted to the north facade in the same satin gray, extends the branding across the building.
• An illuminated address sign over the entrance. Above the entry canopy, a set of 5" deep, internally lit, front-lit channel letters displays the address in brand red. The aluminum returns and trim cap are painted satin red, and the acrylic faces are covered in digitally printed 3M vinyl matched to the brand color, so the address glows clearly at the door after dark.

Mounting Signs on Metal Buildings

Metal panel buildings are common for data centers, warehouses, manufacturing plants, and other commercial facilities, and they need a different approach than brick or stucco. The ribbed panels aren't flat, and the panel skin alone isn't meant to carry a sign's weight. A good install accounts for that:

• Secure stud mounting. Every letter is stud-mounted to the facade so it stays straight and secure through wind and weather.
• Consistent stand-off distance. For halo lighting to look even, every letter has to sit the same distance off the wall. On DC BLOX, that's 1-1/2" across the ribs and valleys of the panels.
• Weather-tight penetrations. Every fastener and wire that goes through the wall is sealed so water stays out of the building.
• Field-verified layout. Placement was verified on site against the building elevations, so each sign lands exactly where it was designed to go.

These details aren't the first thing people notice, but they're what keeps a sign straight, lit, and leak-free for years.

The Interior: 26 ADA Room ID and Wayfinding Signs

A data center has more than offices. It has meet-me rooms, power rooms, electrical rooms, a CRAC gallery for cooling equipment, a man trap at the secured entry, and the data hall itself. Every one of those doors needs a clear, consistent, code-compliant sign. We built a sign schedule that mapped every door on the floor plan to the right sign type and copy, then fabricated three sign types:

• Room identification signs (Type A, 20 signs). These mark rooms like Security, OPS Office, Conference Room, Riser Room, MMR-A and MMR-B, POE-A and POE-B, CRAC Gallery, IT, ELEC-A, ELEC-R, and the Data Hall.
• Directional corridor signs (Type B, 4 signs). These guide people from one zone to the next with copy like "Corridor to Data Halls," "Corridor to Offices," "Corridor to Loading," and "Corridor to Generator Yard."
• Restroom signs (Type E, 2 signs). These include ADA icons along with the room name.

All three types share the same layered construction. A 1/8" acrylic face, painted silver on the second surface (the back side, so the paint is protected behind the acrylic), sits on a frosted white acrylic backer. The copy is raised black Rowmark lettering in Gill Sans, the typeface from the DC BLOX brand guide, with clear raised Braille below it. Each sign is mounted with double-sided tabs and silicone adhesive, so it sits clean on the wall with no visible hardware.

The silver, white, and black palette looks modern and technical, which suits a data center, and using the brand typeface means the interior feels like the same company as the sign on the outside of the building.

Why ADA-Compliant Signs Matter

Under the Americans with Disabilities Act, permanent room signs generally need tactile raised characters, Grade 2 Braille, high contrast between the text and background, a non-glare finish, and proper mounting height and location next to the door. Getting this right matters for a few reasons:

• It helps you pass inspection. Missing or non-compliant signs can hold up a certificate of occupancy or lead to costly rework.
• It makes your building accessible. People who are blind or have low vision rely on tactile signs to find their way.
• It protects your business. Accessibility issues can lead to complaints and legal exposure.

Working with a sign company that builds ADA signs every day means the details, like character height, Braille spacing, and mounting location, are handled for you.

What a Complete Sign Package Does for Your Business

It makes your building easy to find. Clear, well-lit exterior signs with address numbers help customers, vendors, delivery drivers, and emergency services get to the right place quickly, especially on large or multi-building sites.

It shows you're established. A new facility with professional signage looks like a business that's here to stay. That matters to clients, partners, and the people you're hiring.

It keeps your brand consistent. When the exterior, the entrance, and the hallways all share the same colors and typeface, your brand feels intentional everywhere people go.

It keeps people moving safely. In facilities with secured areas, clear wayfinding helps staff and visitors get where they need to go without confusion.

It works 24/7. Illuminated exterior signs keep your building visible after dark, every night, without any ongoing ad spend.

It's simpler with one team. Doing interior and exterior signs together means one sign schedule, one point of contact with your general contractor, and one schedule to manage.

Is a Halo-Lit Building Sign Right for Your Business?

Halo-lit aluminum letters are a great fit when:

• Your building is visible from a road, parking lot, or across a large site, as with data centers, warehouses, manufacturing plants, office buildings, and medical facilities.
• You want the building identifiable at night for security, deliveries, shift changes, or simply brand visibility.
• You have a solid wall surface, including metal panels, block, brick, or EIFS, that can support the letters with proper mounting.
• Power is available at the sign location, or can be run there during construction.

If you only need daytime visibility, non-illuminated dimensional letters like the ones on the DC BLOX north facade are a cost-effective option. If you need maximum brightness and color at night, front-lit channel letters like the DC BLOX entrance address sign may be a better fit. We're happy to walk you through the options and what local sign codes allow.

FAQ

How much does a halo-lit exterior building sign cost? Pricing depends on letter size, number of characters, logo complexity, finishes, mounting height, wall type, and electrical conditions on site. We provide a detailed quote after reviewing your logo, building, and local sign requirements.

Do I need a permit for an exterior illuminated sign? In most cases, yes. Exterior signs usually need a sign permit, and illuminated signs also involve electrical requirements. Rules vary by city and county, and property owners may have their own approval process. We help you figure out what's needed before fabrication begins.

Can you install signs on a metal panel building? Yes. Metal buildings need secure stud mounting, consistent stand-offs for even halo lighting, and sealed penetrations to keep water out. We plan all of that before install day.

Can you match our exact brand colors? Yes. We work from your brand guide to match paint and vinyl colors to your Pantone specs, just as we did with DC BLOX's red, purple, and gray. We can also provide color samples for approval before production.

What's included in an interior sign package? It depends on your building. Most packages include ADA room identification signs, directional and wayfinding signs, and restroom signs, and some add lobby logo signs or safety signs. We build a sign schedule from your floor plans so every door gets the right sign.

Are your interior signs ADA compliant? Yes. Our ADA signs include raised tactile lettering, Grade 2 Braille, high-contrast copy, and non-glare finishes, and we install them at the required height and location.

Can you work with our general contractor on a new build? Absolutely. We regularly coordinate with contractors on new construction so power, layout, and schedules are lined up ahead of time, and your signs are ready for opening day.

Do you work outside of Metro Atlanta? Yes. As the DC BLOX project in North Augusta shows, we take on projects across Georgia and South Carolina. Reach out and let us know where your project is located.
