Metal portable storage buildings (horizontal) have a size limit of 24’ in length.
12’ wide buildings and wider are measured eave to eave due to Department of Transportation hauling restrictions (excluding Texas).
Derksen portable buildings offers a 5-year limited warranty on materials and workmanship on our standard line of products, and a 3-year limited warranty on our Best Value line of products. We value our long-standing reputation for craftsmanship and quality. We will repair or replace any construction or material defect that does not fall within the reasonable expectation of an outside storage building. Our building materials, such as metal, shingles, treated lumber and siding, are covered by manufacturer’s warranties. There is no warranty on used buildings.
