Corrugated Plastic Signs Are...

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 0.16" 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.
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.

A double-sided corrugated sign I ordered for my house sale turned out amazing. I’ve only had it up in the yard for a few days now, but it’s already drawn a lot of people in. Thanks for the professional service and the quality product.
Our partner recommended that we work with Square Signs to get corrugated plastic signs for our promotional campaign. We were pleasantly surprised with the quality work and timely delivery. It was a pleasure to work with a team as competent as yours.
Many thanks for the eye-catching and quality sign. It looks perfect and serves its purpose. Our clients don’t seem to face difficulties finding their way to the right spot any longer.
