Span Systems, Inc.

Over 30 years of broad international experience in the design, fabrication and installation of tension membrane structures!

Architectural tensioned membrane structures are today’s preferred choice whenever a dramatic, unique architectural statement is called for. We at Span Systems fluently speak the language of curvilinear, anti clastic surface geometries. Whether the initial concept is developed in house or provided by the architect or owner, our expertise can turn any concept into a structurally sound, economic reality. Our complete in- house responsibility from start to finish results in a finished product that is outstanding in every sense of the word. Span Systems provides complete design-build expertise for unique tensioned membrane projects worldwide!

Our Tensioned Membranes are fabricated using the highest quality coated fabrics available today!

PTFE (Teflon®) Coated Fiberglass

PVC Coated Polyester (with Acrylic, Tedlar® or PVDF surface treatment)

  • Complies with all applicable fire-code requirements
  • High translucency for excellent filtration of diffuse, natural light inside and, with interior lighting, creates a glowing signature structure at night
  • Maintenance-free
  • Unaffected by extreme high and low temperature variations
Design
Our certified Structural Designs meet building code requirements for snow, wind and seismic loads as well as fire safety, energy conservation, etc.

Structural Analysis and Design is performed in-house using state-of-the-art large deflection, non-linear finite element analysis, with computer-aided form-finding and patterning of the membrane surfaces.

Design Flexibility
At Span Systems, we work with the designer/architect to turn vision into reality. Options are not limited by specific sizes, widths or configurations.

Spandomes require supports only at their corners. The walls are structurally independent from the roof. Therefore, walls are non-load-bearing and can be made of a variety of materials, including:
  • Fabric
  • Galvanized Steel
  • Masonry
  • Glass
  • Reinforced Concrete
  • Kalwall® Translucent Sandwich Panels
  • Netting and Chain Link Fencing
Wall openings can be of virtually any width and wall systems can be designed to be openable or removable to allow natural climate control. Sunshade/canopy structures without walls are also available.

Fully insulated structures (up to R=30) are optional. Lighting and HVAC can also be provided with any structure.
Structural support members may be fabricated from steel, aluminum, wood or fiberglass.
