The Modular In-Plant Office Designed to Enhance Your Experience

  • 5/8" type "X" gypsum are present on both sides of the wall panels. This provides superior strength, fire, and noise protection
  • Our modular in-plant offices come with structural steel columns that are designed with safer anchored and bolted connections for roof beams
  • End wall steel supports for two story and storage roof designs
  • No exposed steel roof support beams like our rivals have
  • WirePak: modular wiring system for lights, switches, and outlets (not partially wired like our rivals)
  • The Gripper: patented steel wall connection that tightly seals out noise, dust, and temperatures
  • Full 3" or thicker walls (no flimsy thin walls)
  • Galvanized steel wall components finished with baked-on acrylic enamel paint

You can only find quality materials in our products. Each reusable piece is interchangeable between units. The steel design shown is used on storage roofs and two-story office structures.
