These signs are printed on 4mm Coroplast (also known as Corrugated Plastic), which makes them both durable and lightweight. They are easy to carry, store, and install without any tools needed. Enhance your clients’ 4mm Coroplast Signs with various coating options. Choose Gloss Film Lamination to add a shiny and protective layer.

Various standard and custom sizes are available to match the specific needs of your clients.
Material
Material
Coroplast® (also known as Corrugated Plastic, Corr-X, Flutecorr, Hi-Core, and Fluted Polypropylene) is a lightweight, budget-friendly material commonly used for outdoor signage.
Its fluted structure adds rigidity while keeping the material lightweight, making signs easy to transport and handle.
It is also water-resistant and stain-resistant. So, with proper care and maintenance, they can last a long time.
The material used for these signs has a thickness of 4mm.
Printing Type
Printing Type
Coroplast Signs are printed using full-colour CMYK digital printing with UV ink that bonds directly to the Coroplast surface. Our high-quality printing delivers vibrant colours, clear text, and vivid graphics.
UV inks help improve resistance to fading, scratches, and moisture. The ink instantly cures under UV light and makes signs durable and suitable for both indoor and outdoor use.
Single and double-sided printing is available. Double-sided signs can have the same design on both sides or different designs on each side.
Coating Options
Coating Options
Choose from our three coating options to match your clients’ needs. When choosing film laminations, leave at least a 1-inch white margin on all sides of your artwork. This way, the laminate sticks better and lasts longer.
Select Gloss Film Lamination to add a 3mil shiny layer that creates a reflective surface. This scratch-resistant coating adds extra durability and protection.
Choose Dry-Erase Film Lamination to add an extra 2mil layer and create a writable surface compatible with whiteboard markers.
Pick UV Liquid Lamination to add a protective layer that shields the sign and creates a writable surface compatible with whiteboard markers.

Choose the Right Size
We offer various sizes for our 4mm Coroplast Signs, from 6" × 24" up to 60" × 120". Custom sizes are also available up to 60” × 120” to match specific client needs.
Larger Coroplast Signs can be made using multiple panels when the required size is bigger than a single sheet (up to 5' × 10'). Your artwork is divided into separate sections and printed individually. You should mount the panels side by side and align them to form one continuous oversized sign. This process is known as tiling.
Cutting
Straight Cut and Contour Cut Options
Coroplast Signs are easy to cut into standard and custom shapes, making them a flexible choice for a wide range of uses.
Straight-cut Coroplast Signs are cut into standard rectangular and square shapes.
Contour-cut Coroplast Signs are custom-cut to follow the shape of your client’s design.
To order contour-cut Coroplast signs, request a custom quote or contact your account manager or our customer service team for assistance with artwork requirements and pricing.

Flute Direction and H-Stand Options
Flute Direction and H-Stand Options
Coroplast Signs are made from corrugated plastic sheets that contain hollow channels called flutes. These flutes run in a single direction across the sheet, parallel to the longest side. Choosing the correct flute direction ensures the sign fits your clients’ preferred application.
Vertical flutes run from the top to the bottom of the sign. This flute direction is required when using H-stands. This orientation is also preferred when the sign will be mounted without full horizontal rear support, as it helps reduce bending or folding.
Horizontal flutes run from side to side across the sign. This flute direction provides additional stability across the sign's width. This orientation is often preferred when the sign will be mounted without full vertical support, as it helps reduce bending or folding.
No preference means the flute direction will be determined during production based on the most efficient sheet layout. In this case, signs may be produced with either vertical or horizontal flutes, and a consistent direction across all signs cannot be guaranteed.
We offer two H-stand options for our 4mm Coroplast Signs. Both H-stands provide easy ground installation, while the heavy-duty option offers increased durability and slightly more stability in windy conditions.
Regular H-Stand (H-Stake) 10” × 24” 9-Gauge
Heavy-Duty H-Stand (H-Stake) 10” × 30” 1/4” Metal Base and 9-Gauge Upper Posts
