Galvanized steel has been in use in the United States since 1870, and can be found in most houses that were constructed prior to the 1950s. Galvanized steel is still a popular option for roofing and siding on commercial and residential buildings. When cutting galvanized steel, it can be challenging to produce a smooth clean-cut edge. With the proper tools, you can cut both galvanized pipes and sheets with precision.
Cutting Galvanized Pipe
Step 1
Secure the pipe in either a pipe vise or a solid bench vise.
Step 2
Place the rotary pipe cutter on the galvanized pipe, centering the line you need to cut with the blade of the cutter.
Step 3
Apply cutting oil and tighten the knurled handle of the pipe cutter until the blade touches the pipe.
Step 4
Turn the cutter in a circular motion, tightening the knurled handle with each revolution, until the pipe has been cut. Add oil as needed during the process.
Step 5
Smooth any rough edges with a steel reamer.
Cutting Galvanized Sheets
Step 1
Clamp the sheet of galvanized metal securely using a bench vice with your guide lines facing up.
Step 2
Use a circular saw fitted with a 7 1/4-inch fiber blade to cut the galvanized metal, following your guide lines.
Step 3
Smooth any rough edges with a steel reamer.
Warning
Gloves and protective eyewear should be worn at all times when cutting galvanized metal.
Always wear a proper mask to protect your airways when cutting galvanized metal with a circular saw or any other powered device.
