Metal Storage Built to Last

All of our top quality metal storage buildings are designed with durability in mind.  An Elephant Structure is built to last for years to come, with very little maintenance or upkeep required.  We only use premium American-made galvanized steel for our buildings, and we reinforce the frames with added bracing in the corners and center.  The roof and wall panels are 29 gauge heavy duty steel sheets.  The regular style roof is guaranteed to be free of leaks and other defects.

Easy Steel Building Installation

We provide two outstanding options for installation.  If you would like us to install your new steel building for you, we offer FREE delivery and installation with every purchase!  Only a small down payment is needed to secure your order, and the balance is due on the installation date.  On the date of installation, all you need is a level building site.  We recommend a concrete pad or concrete footers for ease of installation, but we will install your new metal storage building on almost any surface.  We include concrete-specific anchors at no extra charge, but non-concrete anchors are available upon request.  If you prefer a DIY project, ask about our steel garage kits!  Any of our building designs can be ordered as a kit building for self installation.  Our steel garage kits are made to be constructed with common household tools, meaning you don’t need to be an engineer to build your own metal building!  Have questions?  Give us a call to speak with a building advisor, or shop online for your steel building today!
