Materials Calculator

Enter your size and get posts, trusses, roof and wall metal, slab concrete and a gravel estimate.

These tools give planning-level estimates from typical values. They are not quotes, engineering or final designs, and results depend on your actual land, local rules and choices. We confirm everything with a free site visit and precise drawings.

How do you count panels?

By covered area divided by the panel width, with an allowance for waste.

How is concrete calculated?

Length times width times thickness, divided by 27 to get cubic yards.
