Raised Vs Flat Expanded Metal

This flattens the strands and bonds surface reducing the thickness gauge and elongating the pattern.

Raised vs flat expanded metal.

Standard expanded metal is often more useful for parts washing applications because the raised centers of the bonds prevent liquids from pooling in the basket. Expanded metal is also produced in a flattened form which is created by rolling standard or raised expanded metal. My grates are 9 3 4 black carbon steel. Because it is sometimes difficult to predict how much expansion will occur in the mesh during the flattening process.

Be sure you get the flattened expanded metal. Expanded metal sheet is made by first creating multiple slits in the sheet and then stretching the sheet. Flattened expanded metal is what results when standard expanded metal is put through a cold rolling steel mill to flatten the expanded metal mesh out. Flat expanded metal sheets are lightweight carbon steel diamond shape openings with a raised surface for traction.

Common applications include walkways screens grills and safety guards. Hot rolled raised expanded metal sheets also referred to as grating or mesh is an excellent candidate for most processing techniques. When considering construction type keep in mind that raised standard expanded metal will have rougher edges around the diamond that can tear meat and foil packs. In many cases flattened expanded metal is a safer choice for these surfaces and is easier to clean.

Standard expanded metal sheets are passed through a cold roll reducing mill parallel to the diamond pattern lwd to form flattened expanded metal. Flattened expanded metal abbreviated f is manufa ctured by passing the metal through a cold roll reducing mill parallel to the lwd. I keep them clean and well seasoned. By flattening the sheet the bonds and strands are turned down to produce a smooth and flat surface reducing the overall thickness and elongating the diamond pattern.

Flattened expanded metal on the other hand may be more useful for certain parts handling applications or for making larger custom mesh baskets slightly lighter by thinning out the. These raised strands can be flattened later in the process if desired. The difference is in the thickness gauge of the strand. This makes the expanded metal mesh thinner flatter and wider longer.

The stretching creates a unique diamond pattern opening with one of the strands protruding at a slight angle. There are standard expanded metal styles and numerous variations in strand width and opening sizes can be produced to create whatever architectural or industrial pattern is required. Expanded grating is milled in a similar manner to expanded metal. Otherwise you will have slivers of steel sticking up that will cause your meat to the grate and can also cause a nasty cut on your hands while handling them.

They are never a problem for me.
