The simple, step-by-step construction process allows you to erect your building in just days without heavy equipment or high-priced skilled labor. The award-winning Miracle Span engineers have also designed your building to withstand the worst that nature and time can dish out. With Miracle Span, you can rest assured that your valuables are protected by the best building money can buy.

The Miracle Span W-Series steel building is our most economical building. Its "round-top" design has proven to be completely reliable through decades of use, from military applications to agricultural, industrial and commercial uses. Today, the W-Series steel building is also being used for everything from bulk and grain storage to workshops to housing with the same great success and longevity that has made it the standard of the Quonset-style building industry.

W-Series steel buildings come in widths from 25'-70', with lengths available in whatever two-foot interval you decide is needed.

Every Miracle Span Building System comes with the arch panels, all-weather caulking and industrial grade bolts with accompanying ballistic nylon washers for a weather-tight fit. Beyond that, you choose your desired endwall configuration, doors and/or any other accessories to customize the building to your needs. You can choose to build your own endwalls and doors, too. Miracle Span can work with you, whatever you choose to do.
