Property site signs are often constructed using 1/2" thick MDO (Marine Density Overlay) plywood, Alumalite (1/4" thick coragated material sandwiched inbetween 2 pieces of aluminum or Alu-Panel (1/8" thick material with a solid sheet of pvc sandwiched inbetween 2 sheets of aluminum. These materials are a popular choice for site signs, as the surface is a smooth, shiny, roller- polished paint finish. Available in all sizes, one-sided or two-sided, MDO and Alumalite signs are usually mounted to 4" x 4" posts with your choice of vinyl lettering and/or digital graphics while Alu-panel signs are best suited for mounting on building or other stationary surface. These types of signs are often found advertising lease space information at commercial developments, displaying company information at construction job sites, and for announcing new developments.
