Industry Leading Durability
Our Plastic signs are made from 55 mils thick, tear-resistant HDPE (High Density Polyethylene) material. Signs are perfect for indoors and limited outdoor use. These signs have a 2-year outdoor warranty, but most signs last longer. Our signs are laminated for enhanced performance. You can clean off graffiti and your graphics are protected. Our Safety First - Report All Accidents To Supervisor Bilingual signs are better than comparable styrene signs, which become brittle and break.

USA’s Oldest Sign Manufacturer
Family owned since 1918, we take immense pride in our signage. Being one of the oldest certainly means we know this business in and out. Our South Dakota factory is the oldest manufacturer of metal signs in the USA. We have been an integral part of safety and convenience our signs have provided over the years.

Signs Give a Warning – So You Don’t Have To
Personally warning people is not always the right solution. Say it with signs! Signs are the safest and the most effective medium to reach out to maximum people on your property.
