General Steel prefab steel buildings are the perfect solution for those looking to build a cost-effective, durable, and fully customized three-car garage.

Whether you’ll be storing cars, trucks, ATVs, or something completely different, an engineered steel building from General Steel will give you the flexibility to design and build a three-car garage that will last for decades.

The Power of Clear-Span Framing

C-channel or I-beam construction of your new steel three-car garage results in a building that is as tough as nails while also providing ample interior space to park vehicles, store equipment, and even add an office or administrative area.

Pre-kitted steel buildings from General Steel allow for up to 200 feet of uninterrupted interior space, giving you more design options and floor plan choices to bring your three-car garage dream to life.

For more than 30 years, General Steel has been designing, kitting, and supplying the highest-quality steel buildings in the industry. And, today, we’re proud to offer an unmatched 50-year structural warranty on all the engineered steel buildings we sell.

That’s long-lasting confidence you can feel great about!
