Attractive. Versatile. Durable


Unique frameless steel building system offers visual appeal, creative versatility, and durability. While capitalizing on a construction technique that saves time, labour and materials.
Frameless steel buildings constructed with an engineered panel system. Eliminating the need for structural steel. This unique system allows us to offer low cost, energy efficient solutions.
Frameless steel buildings offer obstruction-free spans of up to 95 m (313’). Completely independent of structural elements such as columns and rafters. This provides our customers with unparalleled flexibility.
The lack of structural steel helps give our buildings an insulation advantage. Inexpensive batt insulation installed to the interior with insulation supports. Minimizing the energy loss caused by thermal bridging. The wall system also accepts a variety of types of insulation. From spray-on to strapping and batts.

Energy Savings Benefits

Clean Ceiling & Attic System

Natural ceiling providing a bright clean interior allows for fewer light units and lower energy bills. Natural ceiling means no exposed roof trusses, while providing a bright clean interior with high reflectivity.

This allows for a reduction in the lighting requirements resulting in reduced energy costs. Our obstruction-free interiors offer easy climate control, which also delivers lower operating costs for our customers.

The attic cavity can easily accommodate inexpensive, blown-in insulation with an R-Value up to R60 which offers excellent protection against extreme heat or cold.

Additionally, the ventilated attic helps deliver lower energy bills and eliminates the risk of wet, saturated insulation.

Foundation & Erection Process

The FRAMELESS wall system uniformly transfers the load to the foundation eliminating expensive, heavy foundations, piers and columns, found with other buildings methods. No heavy lifting equipment is required for erection since there is no structural steel.

Benefits to our Panel and Wall System

The entire system is manufactured from heavy gauge engineered panel with an exclusive roll form corrugation process that provides structural integrity.

  • 41″ wide panel are bolted together at 6″ intervals on the seam and footing channel with 3/8″ plated bolts.
  • Walls and roof panel are manufactured from galvanized, galvalume or stainless steel depending on requirements and are available in a variety of colors in both 4 ½” and 71/2″ corrugation
  • No heavy lifting equipment is required since there is no structural steel.

Our wall system uniformly transfers the load to the foundation eliminating expensive heavy foundations, piers and piles that are required with other building methods

  • Footing channel manufactured from galvalume material, eliminating the potential for corrosion.
  • Wall system can incorporate windows, overhead doors, glass, wood, pre-cast masonry abs cladding materials to provide creative design flexibility.

Benefits to the Roof & Ceiling System

The frameless technology delivers lower costs because of its uniquely versatile roof system.

  • Roof system consists of a corrugated roof and ceiling panels, joined by a lightweight, bolt together truss.
  • Roof system provides a ventilated attic that lowers energy cost and eliminates the potential for wet insulation caused by condensation or leaks in light gauge roof cladding found in other building systems.
  • Air movement is provided through die stamped louvers in end panels.
  • In more extreme environments, mechanical ventilation can be easily incorporated.
  • Attic cavity easily accommodates cost effective blown in insulation.
  • Sealer applied on ceiling panel seam lines creates a vapor barrier and on roof panel, seam lines provide a weather-tight system.
  • The cavity can also accommodate wiring, HVAC ductwork and pipes.
  • Unlike other construction methods, attic trusses can be designed for varying load by changing the gauges. This allows the roof system to accommodate heavy loading capacity roof equipment; there is no need to change the building’s interior or exterior dimensions.


Ideally suited to rinks, arenas and other recreational facilities. The FRAMELESS convex style offers surprisingly low-cost construction for clear spans up to 100 meters.

A lightweight strut system separating the roof and ceiling provides partial load stability. Electrical lines can be hidden in the attic area, providing clean, clear surfaces for maximum appeal.

Insulating the attic is simple with the use of blown-in materials.

  • Cost effective design allows for low construction cost
  • Energy efficient attic
  • Roof system can be designed and installed on other conventional load bearing wall systems
  • A roof can accommodate heavy roof equipment


Our flat roof systems offer clear spans of up to 350’ (106.7 m), with the option of cantilevering up to half of the building’s width with no structural steel columns.

The DUBL-PANL roof is composed of two separate, continuous chords of steel panels, joined by a lightweight strut assembly. Both are long-wearing. A factory-applied finish of durable “silicone Polyester” may be ordered too.

  • Roof incorporates a slight slope to provide drainage
  • Roof system can be designed and installed on other conventional load bearing wall systems
  • Roof system can accommodate HVAC and other roof equipment
  • The system can incorporate interior beam and columns to achieve greater building widths


The BEHLEN Single Panel design is a simple economical method for building clear spans ranging to a maximum of  25′ or 7.6 meters.

  • Roof and wall panels bolt together to form a self-supporting structure. Wider spans can be achieved with the use of structural beams and columns.

    The Single Panel system leads to considerable savings in construction time and materials.

    The cost of a built-up roof is avoided, and the roof can be strapped and insulated with economical fiberglass bats and finished to any desired appearance.

    For smaller commercial structures where construction efficiencies and budgets are the consideration, BEHLEN’s Single Panel design is the answer.

    The pleasing look of the flat roof blends in well with modern industrial or commercial developments making it an excellent choice for workshops, garages and small commercial operations.

    • Roof panel is supported by the FRAMELESS structural wall panel
    • Can incorporate beam and column to expand wider
