Assembly and Care

When putting together your Duramax Imperial Metal Garage, use hand gloves and eye protectors to prevent injury. Besides the parts sent in the kit, tools you’ll need to assemble the shed include a drill, screwdriver, adjustable pliers, level, tape measurer, plumb line and carpenter’s square.

Be sure to assemble your garage shed on a solid, level foundation that allows water to drain away from the site. We also recommend clearing your large metal shed of snow after each snowfall.


Duramax garages come with a limited 10-year warranty from the date of purchase. In the event of a material defect or workmanship that happens during normal use, the manufacturer will send the original buyer a replacement part, free of charge, with proof of the date of original purchase.
