MDM Products 30x40 Buildings are designed for heavy commercial, agricultural and industrial use. From the heavy steel galvanized frame to unique dual cover tensioning system, the building is heavy duty from front to back. Typical uses include large workshop areas, animal protection, long term jobsite storage, and multiple truck or car storage. Completely packaged and ready for quick assembly, the frame is the heaviest available in single tube construction. All frame components are made from heavy galvanized materials. Main Cover, Door, and All Fabrics are made from Long-Life UV Resistant, Fire Retardant Polyethylene with woven backing.

All fabric components feature heat-welded seam construction. Unit features a unique dual cover tensioning system that allows quick adjustment both front-to-back and side-to-side. The easy-up Door can be winched up from outside the building with little to no effort. Wind release flaps on both sides allow for wind absorption. Long lasting cover design provides for run-off of rain, or melting snow, to avoid water getting in through the perimeter of the cover. Each unit comes equipped with both a set of 14 earth anchors and a set of Auger style anchors to secure the unit at all strategic points.
