Details and Specifications


Features and Benefits


  • Superior Wall Panels:   

Panels that use gypsum board have 2-pieces of 5/8 inch thick fire rated type X gypsum for superior sound and fire resistance (as opposed to 1/2 inch regular gypsum of our competitors).  Panels that use steel skins use 26 gauge - galvanized steel with a baked on acrylic enamel finish.  All wall panels are fully fabricated for quick and easy assembly, and are similar in size so that each wall panel is interchangeable with any other.

  • Universal Post Connections:   

Our wall panel connecting posts are universal, interchangeable and made from durable galvanized steel with a baked on acrylic enamel finish. Some competitors use different and non-interchangeable post types when electrical or doors are being used, and some don't have posts at all. The post connection is what gives the modular office its unique advantage over conventional construction - the flexibility to change the wall panels as needed. When components are not universal this benefit can be lost. 

  • Heavy Duty Over sized Doors:

The Door is the only moving and most often used part of a building.  A quality door will give you years of service, a cheap door can give you years of problems.  We only offer high quality doors.  Our doors are the best in the industry.  The door is the cornerstone of a building's quality.  Cheap doors do not last and are always causing operational problems.  Our doors are 20 Gauge Heavy Duty Steel, 1-3/4 inch thick, with a heavy 16 gauge steel frame.  We have an exclusive TiteSeal gasket system to seal out noise and dust.  Doors are over sized 3' wide x 7' high for easy access.  The finish is a powder coated durable finish for long lasting good looks.  Each door includes heavy duty steel mortised hinges, a stainless steel lever lock set, is pre-assembled, pre-hung and completely interchangeable with our other panels.  

  • Steel Roof Deck and Acoustical Drop Ceiling:

We provide a 22 gauge corrugated steel B-Deck for the roof over our modular offices to protect against noise and dust, and we provide a heavy duty industrial grade acoustical drop ceiling for lights and concealing mechanical duct or conduit in the plenum. 

  • Electrical Packages:

We offer two types of electrical packages, one with wiring, which is a modular quick connect WirePak system, not to be confused with a simple pre-wired system that still requires an electrician to do the bulk of the wiring work, and a standard package without wiring.  Each system includes lights, outlets and a breaker panel.

  • Wood Crates:

We use wood crates to ship our wall panels.  Some competitors use shrink wrap and hope for no freight damage. 

  • Easy Installation Instructions:

Our system is designed to be installed quickly and easily by your own personnel and with common hand tools.  If you do not have the personnel available we can arrange an installation crew to handle the assembly.
