Sig-num Sign System

Outstanding Durability with Unified Presentation for Gardens, Arboretums and Parks

MPC's Sig-num Sign System is the first landscape signage system to answer the need for permanent environmental resistance. Sig-num is designed so that the information plate is predominant. Sign frames, stakes and hangers are engineered to provide maximum strength with minimal appearance.

Our sign system uses the proven durability of Metalphoto® coupled with discrete frames and hardware to identify flowers, plants, bushes, trees and other attractions in exterior or greenhouse settings. Metalphoto plates are imaged using a sans serif font for utmost readability. The frames are of sturdy ABS plastic in a standard black color with non-glare finish (other options available by request). Hardware options available for ground level identification, on tree trunks or branches, or bushes.
