On a standard-sized single-story home, you can anticipate to pay $3.50 to $6.50 per square foot or $350 to $650 per square installed. On a double-story home, expect to pay $5 to $10 per square foot or $500 to $1,000 per square foot installed. The price varies depending on the type of material you get and where you buy it. Flat-packed metal is available in various sizes and shapes. It's usually sold by the roll or pallet and typically contains 10-20 layers of metal with an average thickness of about an inch. You'll generally need a lot more flat-packed metal for large projects because each panel isn't as thick as rolled metal. Sheet metal usually comes in 40-foot rolls and consists of 1/4-inch thick steel plates that are roughly 20 feet long. The price depends on the type of metal you want and where you buy it but it's usually $125 to $200 per linear foot. For example, if you wanted to make a kitchen countertop from sheet metal, you could spend around $60,000 for a quality product that will last for years if properly maintained. Corrugated metal is similar to cardboard in appearance and composition but it's stronger and can withstand heavier loads.
