High Quality I-Beam Buildings by Duro Steel
Highly versatile and perfect for any commercial industrial, farm, or consumer application. Each building is custom designed to your specification, and still accommodates your county wind and snow load. It will meet or exceed industry standards and regional requirements.
Our steel commercial buildings, with few width limitations, allow you to erect huge metal buildings with clear spans widths of 100 to 200+feet (30-60+ meters). An excellent choice of American-made structures: from airplane hangars to mini-storage type buildings with multiple interior units with individual exterior doors.
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. End walls may be provided by the manufacturer, or you can build your own. 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.
