24×30 C-Channel

Our 24×30 C-Channel is a great option if you're looking for an all steel building at a lower initial investment than an I-beam building. This building solution is popular among those who need to add a detached one car garage, storage or farm building. One important advantage this building package has over the I-beam alternative is that it comes with one 3070 man door and one framed opening that can be outfitted easily with a sectional door.

Frequently Asked Questions

What's the difference between a sectional and roll up door?

A sectional door opens manually or by motor along a track parallel to the ceiling. Roll up doors coil into a drum above the opening.

What types of insulation are common in metal buildings?

Batt insulation is the most economical and common followed by insulated panels. Spray foam is not recommended.

How do I make my steel building look less like a "steel building"?

We offer GenStone faux stone, rock and brick that can be installed directly to the metal siding. GenStone provides the look of these materials at a more economical price.
