Tension Fabric Buildings, Space Frame & Prefabricated Frame-Supported Structures

Big Span Structures designs, engineers, fabricates and installs custom steel truss clearspan structures for various industry uses. Instead of form driving function, our structural solutions are developed to best satisfy the project’s needs. For construction conditions requiring large clearspan widths without intermediate posts or supports, we provide a range of structural solutions, including tension fabric buildings, space frames, and prefabricated frame-supported structures.

These structures are the perfect structural solution for large aircraft hangars, waste management, mining, fertilizer, minerals, and petroleum.

Tension fabric buildings

A tension fabric building, also known as a fabric structure or building, is constructed using a lightweight and flexible membrane material, typically made of polyester fabric coated with polyvinyl chloride (PVC) or polyethylene. The structural framework of a tension fabric building is made of steel or aluminum, and it consists of arches, trusses, or rigid frames.

Space frame structures

A space frame structure is a form of lightweight construction used in architecture and engineering. It consists of a three-dimensional framework of interconnected members, typically made of steel or aluminum, that work together to provide structural support. Space frame structures are known for their high strength-to-weight ratio, which makes them suitable for large-span and column-free spaces.

Prefabricated frame-supported structures

A prefabricated frame-supported structure refers to a construction method where the primary structural elements of a building or structure are manufactured off-site in a factory and then assembled on-site. The structure is typically supported by a frame system consisting of pre-engineered components, such as beams, columns, and trusses, that are manufactured and pre-cut to precise dimensions.

Aircraft Hangar Buildings

Big Span’s adept team of design principals and project managers have successfully designed, engineered, fabricated, and installed multiple aircraft hangars of varying styles and clad with PVC or PTFE membrane for applications from large commercial and passenger jets to light-weight, deployable, radar-ablative hangars for military aircraft to temporary and permanent wing/tail maintenance enclosures.

Optimized Installations

Big Span Structures designs and fabricates all of our rigid space frame systems utilizing highly specialized engineering techniques to optimize efficiency in terms of the time, manpower, and equipment required to complete the bolt-up installation process. Whether your design requirements call for a standard planar space frame or a dramatic, visually-striking rolled arched showpiece, Big Span’s world-class designers and engineers are uniquely equipped to deliver streamlined solutions that are ready to use in as little time, with the smallest expenditure of resources possible. We specialize in long-span framed structures with width spans of 250 feet and higher and lengths ranging anywhere from 100 feet and more.
