High Quality Arch Buildings by Duro Steel. Duro Span hut is defined as any self-supporting structure, usually in an "arch" or curved shape. There are no interior posts, trusses or support beams of any kind.
The exterior sheeting is the building. To assemble an Duro Span building, you first layout each individual section of the arch on the ground each section is usually no bigger then 8-12 feet long (3-4 meters).You bolt all the sections together to make the first arch. You pull up the assembled arch and attach it to its foundation. Each additional section is assembled in the same manor and attached to the other standing arches. Each arch is usually about 2 feet wide (1/2 meter). To make the building longer, just add more arches. There is no limit as to how long this building can be.
Unique to the Duro Span arch type steel building is you can leave one or both ends completely open without losing the integrity of the structure.
