Sign posts and light poles from Signature Streetscapes are extruded of solid aluminum, and coated with the highest grade long-lasting, rust-free powder coat finish. Both 3" and 4" aluminum posts are available in a smooth, fluted, or square design. Custom lengths and colors are available, so please give us a call or chat using our chat feature for more information! While designed for direct burial, the aluminum sign and light posts can be made breakaway-compliant by using the V-LocŪ breakaway system. Other post hardware available includes breakaway couplers.
