Micro Expanded Metal

We have developed an extensive range of products and offer expanded metal in steel, nickel, titanium, stainless steel, copper, and aluminum in various sizes, widths, and meshes. Micromesh is used for industrial applications in the filter, (petrol)chemical industry, aeronautics, automotive and electrochemical fields. Their superior strength and versatile size lead to improved performance at a minimal cost.

Micro Expanded Metal Advantages

• Outstanding mechanical strength (Anti-ravel and Flexible)
• Micro expanded metal is a cost-effective alternative to perforated metal – especially when using high-value raw materials
• Can be manufactured according to the end user’s exact requirements
• Precision expanded metal mesh product for specialist industry needs
• Can be used in many fields including engineering and manufacturing

 Terminology

• Flattened Expanded Metal V.S Standard Expanded Metal

1.1 Expanded Metal Terminology:

1.1.1 bond, the solid intersection of two strands.

1.1.2 camber, n-the bow of a side or edge from end to end from a straight line.

1.1.3 diamonds, n-open area of metal after expanding.

Most expanded metal open areas or patterns are uniform diamond-shaped, but they may also be hexagonal, louvered, asymmetric, square, or other shapes or combinations thereof.

1.1.4 edge configuration, n-refers to the edge condition of a sheet, whether it is closed diamonds (bonded) or open diamonds (random) produced by shearing.

1.1.5 expanded metal, n-a rigid sheet of metal that is simultaneously slit and stretched creating an open diamond pattern.

1.1.6 flattened, v (F)-expanded metal that has been cold rolled after expansion.

1.1.7 flattening, the process of producing flattened expanded metal.

1.1.8 grating, n-expanded metal that is produced from heavier sheet.

1.1.9 levelness, n-(flatness of sheet), sheets shall be free from waves or buckets that are more than 1–1/2 in. from a plane surface.

1.1.10 LWD, n-nominal dimension, Long Way of the Diamond.

1.1.11 LWO, n-Long Way of the Opening.

1.1.12 regular-raised-standard, n-(R) expanded metal as it comes from the press. The strands and bonds are set at a uniform angle to the plane of the sheet.

1.1.13 SWD, n-nominal dimension, Short Way of the Diamond.

1.1.14 SWO, n-Short Way of the Opening.

1.1.15 shearing, n-cutting the sheet to a specific size or tolerance.

1.1.16 squareness, n-the dimensional variance a side and edge are out of square.

1.1.17 strand thickness, n-thickness of the base metal.

1.1.18 strand thickness, n, and strand width n-can be varied to create different expanded metal products for different applications.

1.1.19 strand width, n-amount of material fed through top and bottom dies to produce one strand.

1.1.20 taper, n-edges of a sheet that deviates from parallel

How to order Micro Expanded Metal?

Please Specify:

• Material: Titanium, Nickel, Carbon Steel, Aluminum, Stainless Steel 304 Or 316, etc.
• Type: Standard/Raised, Flattened
• Quantity: number of pieces – full size or cut pieces required
• Piece Size: width (SWD) x length (LWD)
• Shearing: bond or random. Please check the below photo for reference
• Finish: hot-dipped galvanized, PVC coating, PVDF coating, Pt coating, special, if any

Item No.: typically expanded metal is specified like the following examples:

3/4 #16 S 3′ SWD x 6′ LWD Aluminum

• – 1/2inch= Short Way Of Diamond Dimension
• – #18 = Gauge (Usually not AWG, BWG, SWG, should be Washburn & Moen)
• – “S” = Standard (“F” would indicate flattened)
• – 3′ SWD x 6′ LWD = size of sheet width x length
• – Aluminum = material
