How To Bend Corrugated Sheet Metal

One downside is that the metal sheets have a susceptibility to denting both in installation and during hailstorms.

How to bend corrugated sheet metal.

Draw a line along the section you want to bend using a black felt tip marker. Line up the edge of your plywood with the bend marks on both sides and put something very heavy on it. To clamp efficiently lay your sheet metal on the top surface of your straightedge with the drawn line perfectly aligned with the outside edge of the sheet metal. Step 2 move the metal to the edge of a table.

Once the corrugated tin roofing is secured use a piece of wood with an angled end and a hammer to create a flattened line across the bend. Set a straight edge along the section as you work so your line is straight. A corrugated metal roof is quieter than pvc when it rains. Use a rolling technique to bend sheets of metal roofing.

Some metals such as steel can be heated prior to rolling to promote an elastic effect. If your sheet metal is too thick you may need special machinery like a brake or a torch to bend your sheet into the desired shape. Clamping your sheet metal to the straightedge is a must. Otherwise the sheet metal is almost certain to shift as you bend it resulting in a bad bend.

You can use a tape measure or ruler to measure the thickness of your sheet metal. Then slip another sheet of plywood underneath the sheet metal all the way back to as close to. Determine the thickness of your sheet. Rolling can produce a maximum bend of 360 degrees in most forms of metal.
