Our design team can create a inplant office to abide by your industry’s specific requirements, whether its sound, fire, or insulation factors.

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.

Differences That Matter For Your Mid-Rise Inplant Office

  • Diamond Coat: 8 Mil vinyl wall finish that's durable and maintenance free (33-100% thicker than our rivals)
  • Easily cleanable smooth wall finishes so particulate does not get trapped in a coarse surface (like it does with our rivals products)
  • ToughWall: great value option, 24 gauge galvanized steel wall facing, finished with baked-on acrylic enamel paint
  • 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...
