Our prefabricated mid-rise modular in-plant offices for sale are ideal for separating office personnel from the rest of the warehouse or manufacturing plant. Adding a mid-rise industrial office to your facility offers ample space for workers to comfortably do their jobs, with plenty of room for desks, chairs, cabinets, and more. The elevated structure of these offices gives you the ability to store items underneath or over any on-the-ground obstructions, optimizing space utilization and organization.

With an elevated view of the workplace, your employees can easily monitor operations, identify and address any issues or safety concerns, and ensure that everything runs smoothly and efficiently.

This bird's-eye view also allows for better communication and collaboration between different departments, as employees can quickly and easily communicate with one another from their elevated positions.

Let us help you optimize your workspace with our top-quality mid-rise modular in-plant office structures. Contact our team at National Partition today to learn more about how we can create a customized solution that meets your unique needs and budget.

National Partitions Structural Design

Mid-Rise Inplant Offices Engineered To Be Better

  • 5/8" type "X" gypsum on both sides of the wall panels. This provides superior strength, fire, and noise protection
  • Structural steel columns 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

We only offer materials of the highest quality and performance, and every piece of the system is designed to be universal and reusable. Steel design shown is used on storage roofs and two story office structures.

  • 9' standard wall height, provides a more comfortable work area with higher ceilings. (other heights avail.)
  • MaxDoor: heavy duty and larger steel doors, 40"x 84", with a thicker 16 gage gasket sealed jamb
  • MaxLite: taller standard windows at 48" for maximum light and visibility
  • Matching wall components for a more attractive appearance (no zebra stripes)
  • Shipment from stock. We stock our most popular, 9' high beige walls for faster lead times
  • Delivery and Installation with our truck and factory trained employees

I have 5 National Partitions inplant offices in our factory. The offices are all good quality and built to last. They are truly modular as I have even moved one 7 years after it was originally installed...
