Reflective Signs Are Hard to Ignore
Our Magnetic High Intensity Reflective Signs offer extra visibility in dark and dim light conditions. Reflective surface means light thrown from headlights will reflect back making the sign more readable.br>
3M High Intensity [“HI”] Reflective
3M High Intensity reflective signs offer exceptional reflectance - especially when approached at an angle.

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.

Industry Leading Durability
NFPA Sign Kit includes a set of fifteen 3" digits (three each 0-4) and six NFPA symbols (one each: Acid, Alkaline, Corrosive, Oxidizer, Use No Water and Radioactive). This kit is most popular for chemical tanks. The 32 mil thick magnetic NFPA placards snap permanently onto steel surfaces. This is the same material that we use for our truck signs (that stay on at highway speeds). But, as ratings or chemicals change, signs can be removed without damage. Ratings are applied to the top of the sign. Just remove the liner from the die cut digits/symbols you want to use and apply them to the NFPA sign.
