Expanded metal is sometimes considered an alternative to sheet metal or wire mesh. It combines some of the best features of both—providing a material that is stronger than thin wire mesh and has better air flow and drainage than sheet metal. In fact, it's an excellent option for custom wire baskets that need more tensile strength than wires can provide. Additionally, expanded metal cuts down on the need for extra welding operations compared to using individual steel wires, making it faster and easier to complete sturdy baskets.
Overall, stainless steel expanded metal baskets are incredibly tough and versatile—especially when made of highly-resistant metal alloys such as grade 316 stainless steel. They’ve got a variety of uses across just about every industry Marlin Steel works with and, for that reason, it’s worth exploring.
In bond shearing, the shear line falls through the bonds. The result is an edge configuration of all closed diamonds. For bond shearing the resultant dimensions must be in a multiple of the full diamond dimensions.
In random shearing, the shear line falls at random points on the mesh pattern. Edges are open and diamonds are not matched. Random shearing is necessary when the required overall dimensions are not a multiple of the full diamond dimensions.
Expanded metal is manufactured by slitting and stretching (expanding) the metal sheet with a die creating diamond / hexagonal shaped holes in one step. The connecting metal strands are called bonds that are lie on top of each other creating a raised effect.Raised expanded metals are also called “regular” or “standard” expanded metal.
What is Expanded Metal Mesh?
Stainless steel expanded metal mesh is made of a single solid sheet of compressed and stretched material. The expanded metal grating is useful for heavyweight custom parts washing applications, as well as providing open space for air flow and drainage.
Types of Expanded Metal Mesh
There are two distinct varieties of expanded stainless steel mesh used for baskets: standard and flattened. The term “standard expanded metal” refers to the metal as it comes out of the expanding machine. On the other hand, flattened expanded metal is what happens when standard expanded metal is put through a cold rolling steel mill to flatten the expanded stainless steel mesh.
Here is a brief list of useful stainless steel expanded metal terms:
EXPANDED MESH TERMINOLOGY AND TYPES
|Short Way Diamond
|Long Way Diamond
|Area where strands intersect
|Surface area of metal strips forming diamond
|Gauge of material being expanded
|Flattened short dimension diamond parallel to rolls
|Flattened long way diamond parallel to rolls
|Mesh passed through wire brushes to remove burns
|Mesh roller levelled to reduce curving
Measuring Expanded Metal Mesh
When measuring expanded stainless steel metal mesh, it’s important to consider the overall size of the metal plate after it is expanded, its long and short way of opening, and its strand thickness and width. This is because each of these factors will affect the basket’s performance.
For example, larger LWOs and SWOs mean the holes in the mesh are larger, which improves air flow for the expanded stainless steel mesh basket. On the other hand, thicker and wider strands tend to be stronger than thinner strands.
Comparing LWO and SWO against LWD and SWD helps to confirm the width of metal strands and overall open space of the mesh. For example, if the SWD and LWD of the mesh is 0.5” and 1”, and the SWO and LWO is 0.4” and 0.8”, then the width of the bond should be approximately 0.2” x 0.4”. This would provide a strand width of 0.1”. This would also create an open space of roughly 0.5 inches squared for each opening in the mesh.
Expanded Metal Mesh Uses
As noted above, stainless steel expanded metal mesh has a wide variety of applications across several industries. Some applications companies have used these incredibly tough and resilient baskets include:
Light weight, robust and fire resistant
Handling and construction are easy.
Significant slip-stopping effect
Economical prices and maintenance costs
Very beautiful appearance
Expanded metal is a one-piece metallic mesh without any welds, that reflects a series of uniform openings in diamond shapes. It’s main applications are:
Machine and window guards
Security walls and doors
Platforms and industrial flooring
Bird and animal cages
