Price Increase Notification - 03/26/2018

Due to the recent tariffs on aluminum sheeting, we are implementing a 5% increase on all aluminum signs effective March 29, 2018. We hope the tariffs are short-term in nature, and if so, we will return to our previous price points in the future. This price increase will not affect hardware, posts, decals or faces.

We do apologize for the short notice on this price increase but will honor any prior quotes until April 6, 2018. If you have any questions, please contact our Customer Service office at 800-332-7922.
