The popular 12X20 Metal Garage with Roll Up Door by DuraMax is now available in off white. It is constructed of durable galvanized steel and features a reinforced roof support truss system that can hold a snow load of 20 pounds per square foot. One of the top sellers at Shed Nation, the metal garage is a tremendous value at this size.
DuraMax metal buildings are much more affordable than similarly-sized custom built buildings and are backed by a long 10 year limited warranty. They are perfect for large vehicles, residential storage, commercial storage, or even a workshop studio.
Unlike other buildings which have thin, flimsy walls which are easily dented during assembly, DuraMax buildings uses reinforced steel walls which are 20% thicker and a special rib design for greater dent resistance and strength. The garage is low maintenance and won't fade, mildew, or rot as a wood structure may over time.
Designed for easy assembly with common household tools, the 12X20 Metal Garage can be put together in as little as half a day depending on how much help you have. Though the new off white with brown trim color scheme was developed due to customer requests, it can be easily painted any color to match your preference. It is certain to provide you many years of great use.

Liftgate For Delivery - The liftgate service is offered by the shipper to provide delivery off the truck to your curbside. The carrier will lower the packaged skid off the delivery truck to the ground with a forklift-type device. From there, it is ready for unpacking and moving in individual pieces to the assembly site.
As these kits are quite heavy, if you do not have a loading dock or a forklift available, the liftgate is a recommended option to speed up delivery. The pallet can then be opened at your curbside and each piece is lightweight enough so that they can be individually moved to the assembly site. This usually only takes about 30 minutes or less depending on how much help you have.
