42x30 Steel Barn
Building Description
The 42x30 Steel Barn blends strength and beauty in one fully enclosed design. It features Forest Green walls and roof with crisp Polar White trim. This fresh, classic look stands out on any farm or homestead. The center bay holds vehicles, boats, or tractors with ease. One lean-to fits four-wheelers, mowers, or motorcycles. The other lean-to makes a handy tack room, shop, or supply area. Windows bring in light while you work. Use it as a horse barn or a loafing shed for your animals. It also suits agricultural storage, a home garage, or a workshop. The galvanized steel frame is made to last. Every ProBuilt barn is made in the USA. Delivery and installation are free. Customize it in our 3D designer to make it yours.

42x30 Steel Barn FAQs
Answers about the 42x30 Steel Barn, including pricing, delivery and installation, dimensions, access, and project planning.
The 42x30 Steel Barn is currently listed at $21,155. Final pricing varies by state, certification requirements, and customizations. Free delivery and installation are included. Request a quote for your chosen layout and installation address, and confirm site preparation and foundation costs separately.
The supplied overall size is 42’W x 30’L x 12’H. The layout lists center building: 22’W x 30’L x 12’H (Roof Length 31’); left & right lean-tos: 10’W x 30’L x 9’H, 2/12 Roof Pitch, Center Aligned, Ends & Side Closed. Overall dimensions can include open lean-tos, so use the final drawings to distinguish enclosed storage from covered outdoor space.
The supplied layout encloses the 22-by-30-foot center building and both 10-by-30-foot lean-tos. A front roll-up door serves the center, another serves the right lean-to, and a walk-in door serves the left lean-to. Confirm how you will move equipment between areas when choosing the final layout.
Free delivery and installation are included with this ProBuilt building, so you do not need to assemble the supplied structure yourself. Prepare the site to the agreed installation requirements before the crew arrives. Use the 3D designer to review options, then confirm the configuration and scope in your quote.
Vehicle doors: 10’x10’ Roll-Up on Front Wall (White, Certified); 8’x8’ Roll-Up on Right Lean-To Front Wall (White, Certified). Walk-in access: 36”x80” Solid Door on Left Lean-To Front Wall. Confirm actual clear openings, approach space, and any additional access you need before ordering.
The supplied specifications list 150 MPH Wind Load (Incl. Lean-tos). This does not establish approval for every location. Confirm required wind, snow, and seismic design criteria, permits, setbacks, and foundation requirements with your local building department. Ask ProBuilt which engineering and certification documents are available for your installation address.
