Signs By Benchmark is the only composite-sign manufacturer that controls the sign making process from molding to finishing. A composite sign combines expanded polystyrene (EPS) and a polyurea hard coat to create a seamless surface that is strong, durable and will not rust or rot.

We produce a strong, yet lightweight foam core for each sign. Each can be easily cut and shaped into designs that are almost impossible to create from metal – and more affordable than conventional methods. We spray each sign with our signature polyurea hard coat, giving it uncompromised strength and durability.

We offer several different finishes or decorative elements as a final touch to customize your sign, including:

  • EIFS Brick or Stone
  • Stucco
  • Engineered Stone
  • Sprayed Granite
  • Pole Covers
  • Sign Tops
  • Sign Bases
  • Columns
  • Cornices
  • Logos
  • Lettering
  • Replicas
  • 3D Accents
