Quality & Durability

Worldwide Steel Buildings uses only American recycled steel, and our trusses are built on jig tables to maintain the same quality on every custom storage building. Each truss is then inspected and pre-assembled to ensure that your new metal garage kit goes together the first time. Each of our trusses is dipped in our rust inhibitor / primer tank to help your new mini storage buildings last for decades.

Offering a structural warranty of 50 years, your Worldwide Steel Building is set apart from the standard one to two year warranties offered by many other steel building companies. The premium sheet metal that we use also offers a 40 year warranty giving you a maintenance free building with the durability to last a life time.
