Corrugated Plastic Signs

Corrugated signs are 0.16” thick plastic panels made of coroplast. They’re waterproof and resistant to most weather conditions, so with proper maintenance, they’ll serve you for a long time. As a type of plastic signs, custom printed coroplast signs are commonly used for promotions in real estate, retail, and other industries, construction sites, and sporting facilities. Unique and durable, these sign options also make a cost-effective solution for informative use.

Square Signs offers single and double-sided printing options for corrugated plastic signs. The double-sided printing can be freestanding or hanging to ensure two-way visibility and amplify your message. Coroplast signs are portable and almost as lightweight as PVC signs.

Printing Technology of Coroplast Signs

Corrugated signs are printed using high-resolution UV ink technology that bonds directly to the corrugated plastic surface. This process ensures vibrant, long-lasting colors that resist fading, even in outdoor conditions. Designs are typically printed on flat 0.016" corrugated polypropylene sheets using full-color digital or screen printing, depending on the quantity and complexity.

The ink instantly cures under UV light, making the signs durable, weatherproof, and ideal for both short-term and extended use. Whether you're promoting a business, event, or real estate listing, corrugated sign printing delivers sharp graphics with professional quality at an affordable price.

Shapes for Corrugated Signs

We print corrugated plastic signs with these cutting options:

Square / Rectangle Cut - cut with 90-degree corners;
Custom cut - get your sign shaped like a house, key, or any other custom shapes;
Custom Cut with Border - cut in the shape of your design with a white border;
Circle/ Oval Cut - cut into a smooth circular or oval shape for a clean, symmetrical look;
Rounded Cut - cut with slightly rounded corners to soften sharp edges.

Popular Sizes of Corrugated Plastic Signs

Custom corrugated signs are available in a variety of popular sizes to suit any display need. Standard options include 18"x24", 12"x18", 24"x36", and 36"x48", making them ideal for yard signs, directional signage, and event promotions. Smaller sizes like 9"x12" are great for handheld use or tight spaces, while larger formats provide maximum visibility for roadside advertising or business branding. Whether you need horizontal or vertical orientation, these corrugated plastic signs can be customized to match your exact dimensions and design preferences.

Popular Applications for Coroplast Signs

Coroplast signs are a multipurpose medium used to attract the attention of passersby, be they on foot or in vehicles. They’re versatile with a wide range of applications. The most common uses for these plastic signs include, but are not limited to:

Promotional signs - These signs, similar to yard signs, are popular for displaying promotional messages. They capture the attention of passersby and reach a wide audience with vibrant graphics.
Informative signs - They can also be used to share any kind of information. Just like aluminum signs, they’re a great medium for relaying instructions, business hours, directions, and so on.

Note: Avoid folding your corrugated signs when storing to prevent damage.
