The World’s Leading Supplier of Precision-Engineered Steel Container Cover Kits
The Evolution of the Seacan Roof: From the Original Inventors to Modern Masters
In 2003, our sister company, Future Buildings, revolutionized the storage industry by inventing the original Arch-style (Quonset) Seacan Roof. For over two decades, that design set the global standard for durability.
Today, Toro Steel Buildings has taken that legendary engineering DNA and evolved it. By merging decades of customer feedback with our specialized expertise in modern Cold-Formed Steel Buildings, we have engineered the new and improved M-Model Container Cover.
The M-Model isn’t just a roof; it is a precision-engineered structural system modified to be stronger, sleeker, and significantly faster to assemble than traditional models.
It’s a simple and practical roofing solution for your home or business as it reimagines what would otherwise be unused space and transforms it into something more functional like a storage area or covered workspace. The lack of beams, trusses, or interior supports means that you will have a completely open space to transform in any way you’d like.
Choose your ideal width – 20, 25, 30, 35, 40, 45, 50, 55,60, 65, 70, 75 or 80 feet. They can be designed to any length.
