Clearspan tents use a semi-permanent box beam to support the fabric. These freestanding structures can cover areas of up to 120 feet wide by 300 plus feet long to produce large unobstructed interior spaces. Clearspan tents are a superior enclosure system with flexible design configurations. The kedered roof fabric is fed into special grooves built in the frame. This makes clearspan structures sturdier and more resilient than standard frame tents and allows them to withstand snow loads up to a certain extent.
