Design & Construction Options

Our modular buildings are designed to create highly functional space anywhere inside your facility. The pre-engineered components that we provide to construct our modular buildings are designed to be easy to install so your down time in the area of construction is dramatically reduced when compared to conventional construction. The result is a high quality, durable building that will provide years of trouble free service.

Versa-King 3″

Our most popular wall system. Versa-King systems can accommodate virtually any interior building application. Porta-King uses all extruded aluminum for the vertical post connection and other framing components used in the construction of our 3″ Versa-King modular system. Aluminum is a maintenance free material. Unlike steel post systems it will not rust when exposed to moisture. The extruding process enables tighter control of the tolerances of the various shapes used to create our modular systems. As a result you get a better fit and finish that is possible with a steel post system. The Versa-King post design provides an easy access wiring chase every four feet. Snap-on cover plates allow quick and easy wiring during and after set-up. Versa-King is load bearing making it perfect for two story and / or storage loading applications.

Framing Color Choices: Clear Satin Anodized, White & Beige

Versa-King 1 3/4″

This thinner version of our popular 3″ Versa-King is ideal for those on a budget. This system includes many of the same great features found in 3″ Versa-King but at considerabe cost savings. Porta-King uses all extruded aluminum for the vertical post connection and other framing components used in the construction of our Versa-King 1 3/4″ modular system. Aluminum is a maintenance free material. Unlike steel post systems it will not rust when exposed to moisture. The extruding process enables tighter control of the tolerances of the various shapes used to create our modular systems. As a result you get a better fit and finish that is possible with a steel post system. All components easily dismantle for relocation or increasing/decreasing size of structure -all parts are 100% reusable

Steel on Drywall

This panel includes a finished surface of smooth painted steel laminated to a layer of drywall and includes a UL Class 1 EPS foam insulating core. Like our painted steel on hardboard panel design, the multi-layer lamination design of this panel makes it another very durable panel surface. resistant surface. Additionally the drywall provides a 15 minute thermal barrier required by some building codes. This is another panel surface that is ideal for harsh plant environments. 3″ thick panel thickness has a thermal insulating value of R 10.

Roof Option

Roof Support Angle

Roof support angle is provided to support non-load bearing ceiling systems for structures that will utilize 1 or 2 existing walls to create the four wall enclosure. Our standard roof support angle consists of a thick extruded anodized aluminum angle that is permanently attached to the existing structure to create a secure and level surface for a metal deck or panelized ceiling system.

Roof Option

Panelized Ceiling System

Panelized ceilings are ideal for applications where a tight seal is required. These light weight panels are installed via a tongue and groove side connection. These panels are insulated with an EPS core and are available in 3″-6″ thicknesses to accommodate different span conditions. They include a white painted steel interior and exterior surface.

Roof Option

Load Bearing Ceiling System

Load bearing roofs can be designed by adding structural steel I-beams that are mounted at pre-determined centers to create the required design load. Some heavier load designs, expecially those with large clean span requirements may require additional support via columns either in the wall panels or inside the enclosure. In some cases we will recommend the use of a mezzanine in order to create the appropriate load bearing design.

Roof Option

Acoustical Ceiling System

Our standard acoustical ceiling system consists of a 2’x4′ acoustical tile. The tile is a 5/8″ mineral board with a non directional fissured pattern. The main runners and cross tees are an intermediate grade, white painted galvanized steel. Many other ceiling tiles and grid types are available as options to address specific application requirements.

Roof Option

Metal Decking

Our metal decking is a 1 1/2″ corrugated, painted B deck. We use 22 gauge or 18 gauge decking depending on the span and load design requirements.

Roof Option

Standard Non-Load Bearing Ceiling System

Our standard ceiling system consist of a corrugated metal deck that is anchored to the top of the wall panels. An acoustical ceiling system is then suspended via tie wires to create the finished interior. The gauge of the decking is designed to support the grid work acoustical tiles and lights. For larger spans a structural I-beam will be added to provide additional support.
