Corr-Span Buildings

Corr-Span Buildings
The frameless steel building concept.

One of the secrets of Colony's success in the steel building industry is our unique frameless steel building concept the Corr-Span building. Corr-Span buildings were first introduced in 1949 and subsequently modified and improved as part of a continuous assessment, our frameless steel building concept is still unique in the industry.

The support strength of a Corr-Span steel panel can equal that of a steel girder of the same length and weight. The strength lies in our exclusive "compound" corrugation process which rolls forms sheet steel into 4½" or 7½" deep corrugations embedded with a series of smaller corrugations. These small corrugations enhance the strength achieved with normal corrugation.

Using the finest made galvanized steel in thicknesses of up to 13 gauge for its wall panels. (This is as much as five times the thickness often used in frame buildings), joined together with sturdy 5/8" diameter bolts and polyethylene washers at 41" intervals, and sealed with top-quality strip caulking, Corr span panels form a completely weather tight load bearing shell. Because of this, Corr-Span buildings can be insulated to produce R values leading to significant savings in heating and cooling costs over traditional means of construction including Rigid Frame.

The lack of interior framing allows total use of the building interiors. Costs normally incurred for working around framing are now eliminated. All surfaces are clear and clean for maximum aesthetic appeal and functionality. The Corr-Span wall panels are strong enough to resist normal knocks and scrapes that can damage conventional frame structures. If damage does occur, replacement of individual damaged panels speeds repair and keeps costs to a minimum.

Corr-Span steel building construction also offers tremendous advantages over conventional building construction methods. Because the system doesn't utilize heavy frame components, heavy-duty lifting equipment is not required.

Corr-Span Benefits:

Energy Saving
The exterior shell of a Corr-Span building provides an airtight, watertight seal against the elements. The interior remains dry and comfortable.

In fact, the Corr-Span roof system is so easy to insulate and offers such a substantial improvement in energy efficiency that many conventional buildings install the Corr-Span roofs, which can be purchased as a separate unit.

The frameless, galvanized steel walls will also accept a variety of insulation techniques from spray-on to strapping and batts. The high insular factors attainable with obstruction-free interiors means easy temperature maintenance and fast heating and cooling in Corr-Span buildings, which in turn means lower energy costs.

Cases have been documented where energy consumption in a Corr-Span building was one-half to two-thirds less than in comparable conventional buildings. Savings like that can go a long way toward quickly recovering the capital costs of the building.

Clear Span Ability
The absence of interior posts, beams, wall framing and exposed ceiling trusses allows total design flexibility within a Corr-Span structure. All interior partitions are free-standing and can be altered anytime without structural changes. Interior components can extend fully, wall to wall or ceiling to floor, for maximum space used. The unobstructed ceiling affords better air circulation, better lighting, a pleasant appearance and an unencumbered view.

Uniform Foundation Loading
Since the supporting walls of a Corr-Span building spread the design loads uniformly along the foundation, less elaborate foundation systems are required than for frame buildings, which concentrate significant loads at column locations.

And "less elaborate" translates into "less expensive."

Depending on building size and soil conditions, one alternative that can be considered is the inexpensive floating slab foundation.

Low Maintenance
Maintenance costs for Corr-Span buildings are minimal over a long life span. Corrosion-resistant, galvanized, colour-coated panels stand up admirably to wear and aging. The strong corrugated panels resist dents and roof or ceiling surfaces can be walked on without danger of damage.

Corr-Span all steel construction assures you of years of dependable, maintenance free service.
