Tensile Fabric Structure

Tensile fabric structures are lightweight, flexible, and durable buildings made from fabric or membrane materials, typically supported by a framework of cables, masts, or arches. These structures resist external loads through tension, rather than compression or bending. Tensile structures (otherwise known as tension structures) can hold many forms, although it is generally based on two basic building designs: the Saddle and the Cone. This creates dramatic structural architecture and offers a variety of free-form designs. The tensioning of the fabric eliminates and creases in the membrane and is strong enough to withstand any severe weather and potential damage.Tensile membranes can be used in a variety of situations. They use less material than traditional structures and as a result, weigh less and are easier to transport. They are flexible, robust and can be tailored to your exact requirements. As well as being practical, tensile fabric structures are a showpiece feature that offers an impressive local focal point.
