Raised Vs Flat Expanded Metal

Standard expanded metal sheets are passed through a cold roll reducing mill parallel to the diamond pattern lwd to form flattened expanded metal.

Raised vs flat expanded metal.

These raised strands can be flattened later in the process if desired. Because it is sometimes difficult to predict how much expansion will occur in the mesh during the flattening process. Flattened expanded metal abbreviated f is manufa ctured by passing the metal through a cold roll reducing mill parallel to the lwd. They are never a problem for me.

The stretching creates a unique diamond pattern opening with one of the strands protruding at a slight angle. 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. Flat expanded metal sheets are lightweight carbon steel diamond shape openings with a raised surface for traction. 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.

This makes the expanded metal mesh thinner flatter and wider longer. The difference is in the thickness gauge of the strand. Expanded metal is also produced in a flattened form which is created by rolling standard or raised expanded metal. In many cases flattened expanded metal is a safer choice for these surfaces and is easier to clean.

Expanded metal sheet is made by first creating multiple slits in the sheet and then stretching the sheet. In addition to food grates this product is particularly favored for charcoal. 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. By flattening the sheet the bonds and strands are turned down to produce a smooth and flat surface essent ially elongating the lwd of the diamond.

Hot rolled raised expanded metal sheets also referred to as grating or mesh is an excellent candidate for most processing techniques. Flattened expanded metal is manufactured by passing the raised expanded sheet through a cold roll flattening press. My grates are 9 3 4 black carbon steel. 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 grating is milled in a similar manner to expanded metal. I keep them clean and well seasoned. 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. Be sure you get the flattened expanded metal.

Common applications include walkways screens grills and safety guards.
