Coroplast is also known as corrugated plastic or corflute.
2.5mm – thin coroplast is primarily for bus bench printing where the coroplast sign needs to fit in a tight frame.
4mm – the most common thickness for yard signs as it works perfectly with wire H stands and grommets. 4 mm coroplast signs are the standard choice for most applications.
6mm – heavier coroplast signs are often preferred for sandwich boards or signs exposed to more severe weather conditions. Wire H stands do not work with 6mm corrugated plastic.
If selected, a hole is punched in the coroplast sign and lined with a metal grommet. Grommets can be place on just the top corners, or all corners of the coroplast sign, and as is often the choice or realtors, an anchor grommet may be added to the left side. Â
This fifth grommet is used to connect the sign to the signpost to keep it from swinging in the wind.
By far, 4mm coroplast signs are the product of choice. Most common sizes are 24″ x 32″ or 24″ x 36″. Many customers include corner grommets and attach the sign to a fence with zap straps.
Lawn signs are usually 12″ high and 24″ wide and are ordered with wire H stands. 4mm coroplast lawn signs are usually ordered in large numbers as they are inexpensive. Their message is amplified by placing several of them in close proximity to each other.
These are the cheapest signs, even when printed on both sides.
Enlarging raster graphic files often results in pixilation and unsatisfactory print results. For the best quality output, submit a pdf vector file.  Ensure that your artwork is designed in the size you want printed.
Artwork files for coroplast signs should have a .5″ bleed on each edge. If you need the corrugate plastic flutes to be vertically oriented, please include a note in your cart instructions.

Signs were slightly “not level” to the cut. The orange for my design was very vivid. Overall, signs turned out great and I would order again.
