Product Description

The TMG Industrial 20’ x 30’ Straight Wall Storage Building features a heavy-duty polyethylene cover that is treated to be fire retardant, UV resistant, and water-resistant. The structure is made of commercial-grade galvanized steel tubes that are designed to be long-lasting and relatively easy to assemble. A dirt skirt along both long sides helps protect against crosswinds, giving this shelter increased durability. The roll-up door has a clearance of 10’ for both height and width. This shelter is great for cars, SUVs, boats, and ATVs, as a small shop, for storing farm equipment, and much more.

This shelter is not engineered to handle snow and wind load, the engineering drawing is not available. If you live somewhere snow and harsh winters are a concern, please select our DUAL TRUSS SERIES shelters.
