Expanded Metal

Expanded metal is one of the most economical of all open metal products. Perfect for architectural, commercial and industrial uses, expanded metals come in a variety of forms including:

  • Flattened
  • Standard or Raised Expanded Metal
  • Catwalk Grating

We have expanded metal with diamond sizes ranging from .125″ x .75” to 1.5” x 3.4”. These materials are available in stainless steel, galvanized steel, carbon steel, aluminum, or copper

Unlike woven wire products, expanded metal won’t unravel if cut at one end; the remaining strands continue to hold. It is versatile, with a great variety of sizes, styles and weights offering many choices to suit your needs. Expanded metal presents a virtually impenetrable barrier when used behind drywall or in ceilings.

Our experience with small to large production runs enables us to meet the demands of our customers in a timely and efficient manner.

How to Order Expanded Metal

Quantity – Specify number of sheets

Diamond Orientation– Specify the size sheet required, listing SWD(Short Way of Diamond) first, LWD(Long Way of Diamond) second.
Example: 4’0″ SWD x 8’0″ LWD

Sheet Size – Specify the dimensions of the sheet.

Diamond Width and Length – Specify the nominal width of the diamond SWD
Example: 3/16″, 1/4″, 1/2″, 3/4″, 1″, 1 1/2″, 2″

Gauge – Specify the thickness of the material.

  • In stainless steel and steel this is listed as a number. EG #9, #13, #16, etc.
  • In aluminum this is listed as a decimal thickness. EG .032”, .081”, .125” etc.

Style – Raised or flattened

Type of Material – T304 and T316 stainless steel, arbon steel, both galvanized before and hot dip galvanized after, aluminum, brass, bronze, copper, Monel®, titanium, & other high temperature alloys

Example of typical order:
100 SHEETS…3/4″ …#9F
4′-0″ x 8′-0″ CARBON STEEL

Expanded Metal


Style Designation

A combination of numbers, letters and abbreviations permitting proper specifications of dimension, gauge, style and weight. In expanded metal products, the first number designates nominal dimension, short way of design. The second number completes the designation and may specify the gauge of metal, weight per 100 square feet, or may have some other significance.

Grating products are designated by weight of finished product per square foot.

Standard Expanded Metal

Standard expanded metal as it comes from the press. The strands and bonds are set at a uniform angle to the plane on the sheet. This gives added strength and rigidity, as well as skid resistant surface. Standard expanded metal is abbreviated XM.

Flattened Metal

Flattened expanded metal is manufactured by passing the standard expanded sheet through a cold roll reducing mill. Flattening expanded metal turns the strands and bonds down to provide a flattened surface, reducing the thickness (gauge) and elongating the pattern. Flattened expanded is limited in width (SWD) to 72 inches and sheet thickness may vary plus or minus ten percent form the published dimensions. Flattened expanded is abbreviated FXM.


Grating is a standard expanded metal pattern produced from heavier gauge low carbon steel plates. Strands and the openings of grating are considerably larger than other meshes. It is ideal for use wherever a strong, durable, light weight surface is needed. Although used primarily for pedestrian traffic, grating can accommodate heaviro loads if properly supported.

SWD: Nominal Dimension Short Way of Design LWD: Nominal dimension Long Way of Design

Expanded Ladder Guard

Design Size:

Actual dimensions SWD and LWD. Measured from a point to a corresponding point on the following design.

SWO: Short Way of Opening
LWO: Long Way of Opening
Strands: The sides of the expanded metal design
Strand Thickness: Gauge thickness of metal expanded
Strand Width: Amount of metal fed under dies to produce one strand
Strand Thickness and Width: Can be varied to create different openings. The width of the strand should equal or exceed the gauge of the strand thickness.
Bond: The solid intersection of two strands.
