Comparing lawn bag signs and lawn coroplast signs, bag signs are slightly bigger – 24″x20″ instead of 24″x18″. Bag signs are less expensive than coroplast signs with print on both sides. Besides H-wires (Step Stakes) for coroplast are thinner than U-wires for bag signs and H-wires bend easily under the strong wind. You can see coroplast lawn signs lying on the grass when strong wind happens. They just bend! Usually it doesn’t happen with lawn bag signs if you push a wire frame 4-7″ deep into the ground (7″ is max depth for 30″x10″ Step Stakes).
