Why Plastic Letters?

Plastic letters three-dimensionally show off your business or event. You typically see these types of letters used for business signs. They are affordable, weather-proof, and customizable.

Compared to other materials, plastic letters often prove to be more durable and affordable than other signage options. Plastic letters for signs are made of durable plastic that doesn’t crack, fade, or chip. Every letter comes with a lifetime guarantee. Letters are available in a variety of materials, fonts, and colors. Large plastic letters for outdoor signs can even mimic more expensive materials such as cast metal. Most plastic letters are suitable for outdoor or indoor use and lighting options are available.

And don’t let the idea of “plastic” concern you, our large plastic letters are made of organic ingredients, the plastic is recyclable, and all by-products are recycled. We care about our environmental impact as much as you care about your audience impact.

Installing the plastic letters is simple. Most customers can install the letters themselves without having to hire a sign company or contractor. Every order comes with an instructional installation video. If you have questions, you can contact our customer service team for installation assistance.

Common Uses of Plastic Letters

How plastic letters are used is only limited by imagination. But the most common uses include business signs and event signage. Business lettering may be installed on the business building or on external street or parking lot signage. For events, letters may be used outside the event or connected to event booths. For displays that are meant to be large, free standing letters rather than mounted letters, check out our custom large 3D letters.

Plastic letters help highlight and call attention to your event or business. They also help promote your branding.

Plastic Letters Edging Options

Plastic letters are available with a variety of edging options. Edging most often refers to the sides of the letters, but may also refer to the surface of molded plastic letters.

Laser cut acrylic: clean polished edges
These letters feature laser cut polished edges. The edges are precisely cut and clean looking.

Formed plastic: shaped edges
Formed plastic creates 3D looking letters with formed, shaped edges. Molded edges may be straight or curved. You may add painted borders, flames, and returns.

Injected molded: fully formed edges and surface
Injected molded letters are typically flat on the back and shaped on the front. The formed sides and surface of the letter are formed to create a 3D effect.

Plastic vs Metal Letters

While plastic and metal letters differ in materials and finish, it is also notable that plastic letters are the more affordable option. If you are on a tight budget, cost may be a consideration. However, even though they are lower-priced, plastic letters are durable and suitable for outdoor or indoor uses.

Metal letters are more often used for businesses such as banks or medical offices due to its sharp design and sophisticated look.

Plastic vs Interior Letters

We offer letters specifically intended to be used indoors as well as plastic letters. As you may infer, interior letters or “lobby letters” are designed to be installed indoors. While interior letters are “weather resistant,” they are not designed to withstand intense weather conditions and are made with different materials. Whereas plastic letters are suitable for indoor or outdoor use and include UV protection.

While interior letters can include pigmented colors, the primary finishes available are GemLeaf colors such as brushed brass or polished aluminum and wood imitations such as cherry or walnut. Interior finishes are suitable for upscale applications where you want a “classy” finish such as for medical, beauty, or legal offices.

Mounting Options Explained

When ordering letters, you’ll need to consider how they will need to be mounted. Will you be mounting the letters outside to brick or inside to drywall? Mounting options are available to suit any situation including outside and indoor environments. Mounting packages include required pieces such as screws, pads, plastic blocks, stand-offs, adhesives, strips, nuts, and studs.

Your sales rep will help you choose which mounting option will be best for your situation. Mounting is an additional cost to your basic order. Keep in mind that if you do not install using an approved method, your warranty may not apply. Self-installation is surprisingly easy. In most cases, you will not need to hire a sign company or a contractor. Most customers install the plastic letters on their own. We have a range of mounting options, from plastic mounts or adhesive glue or tape, depending on where your letters will be installed. Your sales rep will discuss the best options for your situation. We send instructional videos and templates on how to install the plastic letters along with your order. We are available to help you with your mounting questions and concerns.

Some mounting options include,

No mounting:

Flat and light letters may be installed using adhesives or double face tape. We have tested and approved Chem-Calc 1200 or GE RTV108 squeeze tubes of clear silicone. Otherwise, always test your adhesive for the installation situation. Heavier and larger letters should be installed with a stronger adhesive than silicone. If in doubt, use a stronger industrial adhesive or epoxy – along with appropriate anchors and/or additional structural support.
