Raised Vs Flat Expanded Metal

These raised strands can be flattened later in the process if desired.

Raised vs flat expanded metal.

This flattens the strands and bonds surface reducing the thickness gauge and elongating the pattern. My grates are 9 3 4 black carbon steel. 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. 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.

In many cases flattened expanded metal is a safer choice for these surfaces and is easier to clean. 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. The stretching creates a unique diamond pattern opening with one of the strands protruding at a slight angle. 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. Flat expanded metal sheets are lightweight carbon steel diamond shape openings with a raised surface for traction. This makes the expanded metal mesh thinner flatter and wider longer. In addition to food grates this product is particularly favored for charcoal.

Expanded grating is milled in a similar manner to expanded metal. Common applications include walkways screens grills and safety guards. Be sure you get the flattened expanded metal. 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.

They are never a problem for me. 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. 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 is what results when standard expanded metal is put through a cold rolling steel mill to flatten the expanded metal mesh out.

Hot rolled raised expanded metal sheets also referred to as grating or mesh is an excellent candidate for most processing techniques. Because it is sometimes difficult to predict how much expansion will occur in the mesh during the flattening process. Flattened expanded metal is manufactured by passing the raised expanded sheet through a cold roll flattening press. Expanded metal sheet is made by first creating multiple slits in the sheet and then stretching the sheet.

I keep them clean and well seasoned.
