This product is composed Coroplast plastic material — a smooth, bright white rigid plastic that is lightweight, yet very durable and weather resistant. These signs are great for both indoor and outdoor use, and have a low-glare, matte appearance. At regular temperatures, oils, solvents and water have no effect on Coroplast which also lends nicely to the endurance of the sign.
Please be aware that the corrugated flute structure results in a very subtle linear effect (faint lines) on the product’s surface.
Heavy-duty large steel H-stakes available as an option on this product. They are black in color, measure 8-1/2″ wide by 36″ tall, and are constructed of sturdy 5/16″ steel.” If using H-Stakes, make sure to place your Coroplast order with vertical flutes. H-stakes are best used on soft ground such as dirt, soil, grass, etc.
