A fabric building is a structure with steel or aluminum frames enclosed by tarps or woven fabric covers. Fabric structures with metal trusses are available in a variety of materials and quality levels, including pre-engineered fabric buildings, "off the shelf” buildings sold at local big box stores and non-engineered structures. All Tentsen Tent fabric storage buildings are pre-engineered to ensure building safety and structural integrity. Our fabric covers are made of UV protected woven polyethylene fabric for maximum longevity. And our steel trusses are hot-dip galvanized after all welding and fabricating, to ensure lifelong corrosion protection.
