The edges of thin sheet metals can be made safe and given additional rigidity by folding the top rim around a thick wire to create a wired edge type of hem.
Wire edge sheet metal.
Metal shaping guru lazze demonstrates how to make bead with a wire edge for fenders or other parts for so you can easily duplicate repair a fender or panel.
1 8 inch wire bead roll set.
Step 7 set the closing wheel to one thickness of metal about 1mm and run down the edge again to give a full length even finish.
Run along the length of the wired edge closing it sufficiently to securely trap the wire all the length.
Using simple hand tools to make a rolled wire edge to a piece of sheet steel.
Sheet metal knowledge menu sheet metal manufacturing and services.
A wire edge fig.
Rolling a hemmed wire edge into sheet metal.
We don t want to curl fully over we want to fold over and then lay the edge out flat against the main part of the sheet.
This stiffens the panel and is good for fender wells or any product details.
The metal in the areas where holes and slots are punched gets stretched and become more tensile which gives more structural rigidity to the sheet metal.
We have a need to put a wire inside the curled over edge of sheet metal thin sheet about 0 020 aluminum.
The difference here is that you put a small piece of metal wire near the edge of the panel and you fold the edge of the metal over it.
I ve started by bending the sheet up 90 degrees where i want to roll to start.
Making the joint mark out the development or pattern of the object to be made allowing an extra 2 5 times the diameter of wire to be used along its top edge plus any other allowances.
This process is similar to that of breaking an edge of the sheet metal in that you re manipulating the edge of the panel to give it rigidity.
These roll sets allow you to crimp a 1 8 inch diameter wire onto the edge of a panel.
Wire edging is a process in which the edge of the sheet metal is rolled over on a metal wire giving the sheet strong edges.
The following sheet metal gauge size reference chart gives the weight and thickness of sheet metal given as a gauge sometimes spelled gage and indicates the standard thickness of sheet metal and wire for most materials as the gauge number increases the material thickness.
