Improperly laying out bend locations on a steel plate will cause the bends to fall in the wrong place and render the piece of plate useless. This situation increases the cost associated with steel fabrication. Forgetting to deduct metal thicknesses from the bend locations during layout is a common reason for incorrect bend locations. Properly measuring the thickness of a steel plate and doing the proper math ensure the fabricated steel plate will have the correct dimensions.

Skill level:Moderately Easy

Things you need

Tape measureSheet metal shearAwlCenter punchHammer

Instructions

1 Lay a piece of steel plate flat on a stable worktable. Measure the thickness of the steel plate by pulling a tape measure across one plate edge. Deduct two times the metal thickness for each bend you will place on the steel sheet to determine its cut length. For example, deduct 1/2 inch for each bend on a 1/4-inch thick steel plate.

2 Cut the steel plate to the correct length with a sheet metal shear. For example, a finished bent piece of steel plate with two legs each measuring 6 inches would have a cut length of 11-1/2 inches if the plate has the thickness given in the earlier example.

3 Mark the location of the bend--minus one metal thickness--at two locations on one face of the steel plate with a tape measure and awl. Align the point of a centre punch with one of the awl marks. Hit the back of the punch with a hammer to make an indentation on the steel plate. Move to the other marked location and place a second punch mark.

4 Move along the steel plate laying out each bend location, ensuring to deduct the metal thicknesses between each bend.
