Step 1

Lay the piece of corrugated sheet metal on a flat surface and use a tape measure to determine where it needs to be cut. Draw a line down the length or width of the sheet metal using a pencil to mark the cut line. You can cut corrugated metal both parallel to the ridges, as well as across the ridges.

Step 2

Hold a magnet up to the sheet metal to determine if it is steel or aluminum. If the magnet is attracted to the sheet metal, then it is made of steel. If not, then it is made of aluminum.

Step 3

Place a pair of straight edge snips at the end of the pencil line, if the sheet metal is steel. Use a pair of tin snips at the line if the metal is aluminum. Both of these tools are basically industrial strength scissors.

Step 4

Cut along the pencil line with the straight edge shears or the tin snips until you have cut the enter piece of corrugated sheet metal.

You would need a diamond metal cutting blade. Has no teeth but diamond or carbide chips for the cutting edge. All blades are labeled on what they cut.

Hi! William is right about the blade. It would be something like this:

ALSKAR DIAMOND ADTVBT 7 inch All Purpose Metal Cutting Dry or Wet Cutting Segmented Diamond Blades for Metal and Plastic Materials (7") https://www.amazon.com/dp/B07H5Q4LXZ/ref=cm_sw_r_cp_apa_i_KYEsEbE8QM26T

For tin and sheet metal, we use tin snips. They are just a hand tool that comes in different profiles such as straight and curved. If you have a lot of tin to cut, try double cuts. They are electric tin snips
