Clamp the aluminum siding, leaving the part that you want bent hanging over the table.
Grab the siding with both hands.
Pull the aluminum siding toward you until you have reached the angle that you want.
Grasp the siding with sheet metal pliers and continue to pull toward you to form a steeper bend with a greater angle.
Continue pulling in the same direction until your siding piece is bent to your satisfaction. Don't alternate the direction in which you pull, as this can cause the aluminum to break.
Things You Will Need
- Work table
- When bending aluminum siding, do not bend it at an angle greater than 90 degrees. A greater bend can compromise the quality of the aluminum and cause it to tear.
