About Non-Combustible Construction

Non-combustible construction refers to a building composed of fire resistant materials, designed to minimize the possibility or spread of fire.  Non-combustible construction is available as an option on Whitley Manufacturing's line of modular buildings.

About ISO Container Based Buildings

ISO Container based buildings can either utilize existing shipping containers that have been retrofitted to your specification, or can be custom fabricated to meet your space planning requirements while utilizing ISO corner blocks and maintaining ISO pick compatability.

ISO containers allow for multi-modal transit of the unit to the site and are exportable for international project sites.  The units are stackable and sustainable (being composed of high recycled / recyclable steel).  Containers can be outfitted to meet your needs and incorporate complex MEP and electrical systems.

Base Frame

Base Frame Shipped Seperate


Base Frame and Lid (Up Over Installation)

Whitley Manufacturing custom designs and builds mechanical enclosures that meet your specifications for a variety of applications. 

Equipment Easily Installed on the Base Frame

Our mechanical enclosures increase productivity by simplifying the installation process. The modular building can be shipped in two sections: the base frame (also referred to as the skid base) and the "drop over" lid module (walls and roof).

Lid Installed After Equipment

Each base frame is engineered and fabricated specifically to fit your equipment. The design considers equipment weight and location, integrated utility conduits and spill containment channels. Once the equipment is installed, the lid section containing the walls and roof structure, is lowered into place and fastened to the base.
