Charleston Sign Manufacturing offers exterior directories and readerboards that are perfect for signage applications requiring information on a wide variety of subject matters.

These directories and readerboards can be used in either illuminated or non-illuminated configurations, and they are custom-made to suit your specific application.

You can choose from either single or double-face configurations, and a variety of message media options are available, from corkboard to changeable sign letters.

All units are built to withstand tough outdoor environments and can be either anodized or finished with our standard acrylic polyurethane finish.
To ensure durability, all Charleston Sign Manufacturing exterior directories feature the same durable extrusions used in all of our products. Additionally, they come with weather-resistant aluminum backing, silicone sealant, and requisite ventilation.

A readerboard is a visual display board that can convey information about products or services, travel, news, or event information.

While traditional readerboards often use simple block letters that must be physically manipulated to change the message, many modern versions use LEDs that can be instantaneously updated to reflect changes to the displayed information.

System Features & Design
The beauty of GPP-CI architectural signage systems are their inherent versatility. Utilizing modular components, the systems can be adapted to virtually any signage application ranging from monolithic designs to interior wall-mounted directories. The GPP-CI systems offer design integrity, aesthetic quality and remarkable economy.

GPP-Charleston Industries maintains a complete in-house paint facility. As a result, we are able to offer single source responsibility and a high level of quality control. In addition, our color matching capabilities are without equal. We take pride in providing full color matching services, usually in a week or less.

Our standard paint finish is an acrylic polyurethane, the most recognized coating for quality, brilliance and longevity in architectural signage systems. 6063 T5 aluminum extrusions are mechanically pre-treated, primed and electrostatically painted.

The finish is then baked on in an oven-accelerated air-dry system. The resulting hard, slick surface makes it impact resistant and able to withstand exposure to most solvents and chemicals as well as heavy traffic or abuse. In addition, the finish maintains

its "just painted" look years after exposure to sun, salt, and corrosive industrial environments.

Beyond our standard acrylic paint finish, GPP-CI can also provide anodized, Kynar 500® or other premium coatings as required. Please call us directly with your inquiries.

All posts and frames are manufactured from heavy duty 6063 T5 aluminum extrusions produced to Aluminum Association standards. Standard sign panels are supplied in .063 to .125 aluminum. Acrylic, fiber glass, Lumasite® or polycarbonate panels may also be specified.

There are a number of ways for a sign to effectively convey the proper graphic image. GPP-Charleston Industries employs state of the art graphics equipment and technology. This allows the architect/specifier the freedom to choose from a number of processes for producing a graphic image. Some of the processes used by GPP-CI include:

  • Applied vinyl copy
  • Precision routed copy
  • Push-through copy
  • Frisketed copy
  • Back sprayed copy
  • Routed dimensional letters
  • Digital print


Our graphics capabilities allow us to offer a variety of options such as logo reproduction, corporate identity programs and sitewide uniformity of graphics.

The Series 750, 750 pylons and Series 1200 are designed for either Illuminated or non-illuminated applications. All units and ballasts are UL approved and are available in 120 or 277 volt configurations.
