Expanded metal is sometimes considered to be an alternative to sheet metal or wire mesh. It combines some of the best characteristics of both - providing a stronger material than thin wire mesh and better airflow and drainage than sheet metal. In fact, it is a good choice for bespoke wire baskets that require higher tensile strength than the wire can provide. In addition, expanded metal reduces the need for additional welding operations compared to using a single wire, allowing for faster and easier completion of robust baskets.

What is Expanded Metal Mesh?

Expanded metal is a type of sheet metal that has been cut and stretched to form a regular pattern (often diamond-shaped) of a metal mesh-like material. It is commonly used for fences and gates, and as metallic lath to support plaster or stucco.

Types of Expanded Metal Mesh

Stainless steel expanded wire mesh for baskets is available in two different varieties: standard mesh and flat mesh. The term "standard expanded metal" refers to the metal that comes out of the expander. Flattened expanded metal, on the other hand, is what happens when the standard metal mesh is passed through a cold rolling mill to flatten the stainless steel mesh.

 

How is Expanded Metal Mesh manufactured?

The way in which stainless steel expanded metal is manufactured depends on the type. In the manufacture of standard steel expanded metal, the thickness of the expanded metal and the thickness of the expanded metal determine the exact dimensions of the expanded metal, although the thickness of the metal strands and the gaps between them are consistent and regular. Depending on the expansion equipment, standard expanded metal may have a slightly rounded appearance. This helps to reduce any risk of wash process runoff collecting in the expanded metal basket.

 

The flattened expanded metal is flattened by cold rolling the steel. This makes the expanded metal grille thinner, flatter and wider/longer. The dimensions of this expanded metal may differ slightly from any original estimate, as it is difficult to predict how much expansion will occur during the flattening process.

The choice between a flat expanded metal and a standard expanded metal mesh depends on the application. Standard expanded metal is usually more suitable for parts washing applications, as the bonded raised centres prevent liquids from collecting in the basket. On the other hand, a flattened metal mesh may be more suitable for certain parts handling applications or for making larger custom baskets lighter by making the mesh thinner.


    

Expanded Metal Mesh Terms

The following is a brief list of useful stainless steel expanded metal terms.

 

Stranded. This is the term for the solid metal part of an expanded metal grille.

Bonds. This is the term for the point at which the strands cross.


The Important Data of Expanded Metal

 The Important Data of Expanded Metal     


Short Simplicity of Design (SWD). The distance between the centres of the bonded strands in a grid when measured along the diagonal of a short diamond. To illustrate this, in a diamond pattern shape like "<>", the SWD will be measured from top to bottom.

 

The Long Way to Design (LWD). The distance between the centres of the bonded strands in the grid when measured along the diagonal of the long rhombus. In the diamond pattern shape "<>", the LWD will be measured from right to left.

 

Short open circuit (SWO). The distance between the inner edges of the keys when measured diagonally across a short diamond. The difference with SWD is that SWO measures the open space, whereas SWD measures the space from the centre of one bond chain to the next.

 

The Long Way Open (LWO). The distance between the inner edges of the bond strands when measured across the diagonal of a long diamond. As with SWO, the difference between LWO and LWD is that LWO only measures the open space, whereas LWD measures the centre of the bonding strands.
