Since 1967 National Partitions has been an industry leader in prefabricated construction for modular offices, enclosures, and cleanrooms.

Illus system


The National Partitions patented systems fully utilize universal components, and a non-progressive design for independent wall panel access.

This design allows you to install the system from inside or outside of the building, and can include a 1-hour fire rated option.

Our interchangeable post and panel connections serve multiple functions, including:

  • Providing a tight seal between connections
  • Concealing wiring for data/communication, electrical, etc.
  • Concealing structural steel so that it’s independent of walls
  • Providing a thermal break
  • Acting as a wall start section to attach to existing structures

Our systems are available in custom and extended heights of up to 40 feet. They are color coordinated so components match the walls, and can be vinyl wrapped to match vinyl-faced walls exactly. We also conceal our structural steel roof beams in the plenum for a better looking structure, which is much nicer than our rivals exposed beam design.

We offer delivery with our trucks, common carrier shipping worldwide, and factory installation, creating a convenient experience for you – no matter where you are located.

Illus performance


National Partitions systems outperform all of the competitors typical designs. We only offer materials of the highest quality and performance, and every piece of the system is reusable! Our designs are easily assembled, redesigned and relocated, protecting your investment for years to come.

These designs are stronger than traditional walls, and the steel designs are solid and safe. They have been sound and fire compliance tested for class "A" flame spreads (E84), and have options for 1 Hour fire ratings (E119), and 4880 compliant walls as required.

We also offer:

  • Sound Deadening – STC 25, STC 35, STC 45 (Hush Core)
  • Durable finishes – Choose from an 8-mil vinyl, galvanized steel with baked-on enamel, a USDA-approved option, fiberglass reinforced plastic and more.

Company Profile

Since 1967, National Partitions has been the leader in pre-engineered industrial products.

No one has built more modular warehouse rooms than National. As the pioneers in industrial modular construction we conservatively estimate that we have produced over 75 million square feet of our products. This makes us the largest and most preferred manufacturer in the nation by far.

Many successful companies are discovering that construction is an area in which they can gain a competitive edge through increased efficiencies and lower costs. With modular construction from National Partitions, you will be able to reduce your costs, improve your productivity and strengthen your control of overall operations costs. Our products are found in manufacturing plants, warehouse and distribution centers, on military bases and in educational systems, among other industries.
