Why Arch

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.

There are wide variations in the quality of Duro Span hut steel buildings based on the type of steel
(gauge, grade coatings, tensile strength) used, the end wall configuration, door options (sliding doors or
overhead garage doors), door openings on the end wall, foundation attachments, interior height, and the
amount of on-site work needed to erect the building. When your shopping for an Duro Span steel
building, be sure you address these important features.

or skill.
• Good choice of buildings with a maximum width of 100 feet.
• Very Secure. Very hard to break into. *Excellent for storing hay, grain or crops, their shape gives
