What is Expanded Metal Mesh?

Our Expanded Metal Mesh is a durable material often used for machine guarding, trailer floors, filters, separators, baskets, awnings, storage bins, rack floors, fencing and walkway floors. Galvanized, aluminum and stainless steel sheet metal mesh are not easily damaged by environmental factors such as water damage and corrosion, making it the perfect choice for outdoor applications. Expanded metal can provide greater traction through its exposed edges, which leads to its use for fashion shows or drainage covers.

Although expanded metal is a strong product, it is a very light material compared to other materials, which makes it an easy-to-install option for security applications. It is also very conductive, which means it can conduct heat and electricity due to the fact that the original sheet has no welds or fractures.

How Expanded Metal Mesh is Manufactured?

Expanded Metal Mesh is manufactured in two ways -- flattened and raised. Raised expanded metal, also known as standard expanded metal, is steel, aluminum or stainless steel in the format in which it has been pressed and placed through expansion. The shearing and stretching of the expansion process create wire bundles and bonds at a uniform angle to the sheet plane. This increases the strength and stiffness of the material while providing a directional non-slip surface. Flat Expansion Metal is manufactured by passing the raised foam sheet through a cold roll flattening press. This flattens the strands and bonding surface, thereby reducing thickness (gauge) and elongating the pattern. Expanded Grating Milled in a similar manner to expanded metal. The difference is in the thickness (gauge) of the strands. Due to the thicker strand gauge, expanded gratings have better load-bearing characteristics and are therefore suitable for a wider range of applications.

 

Expanded Metal Mesh Terms

Here is a brief list of useful stainless steel expanded metal terms:

▴Strands. This is the term for the solid metal portions of the expanded metal grating. In the diagram at the top of the article, the strands are 0.107" wide.

▴Bonds. This is the term for intersections of strands.

▴Short Way of Design (SWD). The distance between the centers of bond strands in the mesh when measured along the short diamond diagonal. To illustrate this, in a diamond pattern shape like “<>,” the SWD would be measured from top to bottom. In the diagram above, the SWD would be approximately 0.372" (0.265" SWO plus 0.107" of strand thickness).

▴Long Way of Design (LWD). The distance between the centers of bond strands in the mesh when measured along the long diamond diagonal. In a diamond pattern shape “<>,” LWD would be measured from right to left. In the diagram above, the LWD would be approximately 1.107" (1" LWO plus 0.107" of strand thickness).

▴Short Way of Opening (SWO). The distance between the inside edges between bonds when measured across the short diamond diagonal. The difference from SWD is that SWO measures open space, while SWD measures the space from the center of one bond strand to the next. In the diagram above, the SWO would be 0.265".

▴Long Way of Opening (LWO). The distance between the inside edges between bond strands when measured across the long diamond diagonal. Like with SWO, the difference between LWO and LWD is that LWO measures open space only, while LWD measures to the center of a bond strand. In the diagram above, the LWO would be 1".

▴Strand Thickness. A measure of the thickness of a strand of expanded metal.

▴Strand Width. How wide a strand of expanded metal is.

Expanded Metal Weights

Expanded metal weights are considered with certain criteria.The weights of these metals are measured by the calculator. The determined weights are of great importance for the strength of the product. If the weight per square meter is not high, it creates a more reliable use depending on the quality design.

As an expanded metal company, we meet with you with many types of products. When you visit our site, you will have the opportunity to review our wide range of products with durable, high quality, cost effective, mild steel, sharp edges, hot rolled metals.

 

Uses of Expanded Metal Mesh

Expanded Metal sheets are used in industrial structures, elevator protection, food industry, chemical and pharmaceutical industry, cement factories, dams, power plants, ship and yacht construction, social facilities and various decoration works.

Since ancient times, people have created barriers from stone or bush to protect vegetables and orchards, as well as animals, and to protect their borders. These are the ancestors of the current wire mesh. It has started to gain importance in elegance on top of the wire mesh used for security purposes today.
