Select Your Alloy:Stainless SteelM12Z-34 in Stainless Steel
Stainless steel is often used for both architectural and industrial wire mesh applications. The vast number of specific stainless steel grades can be manufactured into wire mesh to improve it's performance in corrosion resistance, formability, and aesthetics. Stainless steel is steel with the addition of chromium and other traces elements. The chromium produces an oxide layer at the surface that is known as the “Passive layer”. This passive layer protects and prevents further corrosion. Other metals such as nickel, molybdenum, titanium, manganese are added throughout the many types of stainless steels.
Specifying stainless steel wire mesh provides a natural silver tone aesthetic with the added benefit of corrosion resistance. Banker Wire uses top quality EPQ quality drawn stainless steel wire in all of its wire mesh patterns. Care must still be taken to choose the appropriate grade for it’s intended application. Rule of Thumb: T304 for interior and T316 for exterior. Both grades will have the same aesthetic, however T316 includes molybdenum to its chemistry, increasing its corrosion resistance to salts and acids. Stainless steel can sometimes show rust spots however this is almost always due to cross contamination with carbon steel where free iron is embedded into the stainless steel creating a disruption in the material’s “Passive Layer”. Understanding the alloy and using proper fabrication methods are essential to maintain the desired appearance and longevity of the product.

Plain SteelM12Z-34 in Plain Steel
In the wire mesh industry, plain steel, also known as carbon steel, is a widely used metal available in both woven and welded wire mesh forms. It primarily consists of iron (Fe) with a small amount of carbon (C) and other trace elements, making it a cost-effective and versatile option.
Plain steel wire mesh is manufactured from a wide range of wire diameters directly cold drawn from hot rolled rod. Known for its strength, durability, and magnetic properties, the material represents very good value. Plain steel is widely used in applications where its weld-ability and economy make it a popular option. Its appearance can range from black to gunmetal to silver but is susceptible to rusting when exposed to wet or moist conditions. Plain steel wire mesh is often finished with a secondary coating such as plating, powder coating or hot dipped galvanized to beautify and/or protect it from further corrosion.
Plain steel can be further categorized into two groups known as low carbon steel and high carbon steel depending on the percentage of carbon content. The amount of carbon content affects strength and hardness characteristics in the wire.
While cost and overall workability make plain steel wire mesh a popular choice, corrosion resistance is lacking. Rust will occur rapidly in the presence of moist and salty conditions. Plating or Powder coating are both options to finish this base material for interior applications. For a woven wire mesh specification used in an exterior application, a powder coated plain steel wire mesh will rust at the wire mesh intersections. Please consider a pre-galvanized or aluminum wire mesh as a suitable alternative when a powder coated finish is desired in an exterior application.

Weathering SteelM12Z-34 in Weathering Steel
Compared to plain steel, weathering steel contains a mix of alloying elements that increases its resistance to atmospheric corrosion. Made popular to the industry by trade name Corten, it is meant to rust under the influence of weather. A242 weathering steel develops a patina that acts as a protective layer to prevent corrosion of the steel. Corrosion rates are significantly reduced up to 8 times better than plain steel, making this material suitable to be used in many exterior applications in its unpainted condition. If the surface is damage, weathering steel has self-healing characteristics by its ability to replace the patina naturally.
Weathering steel has an appearance much like plain steel prior to forming a protective patina. After exposure to the elements, the transformation will begin to take place over many shades or rust color. Trace amounts of oils and other lubricants during the wire mesh manufacturing process could remain on the surface impeding the rate of patina. Once removed either chemically or naturally, the development of the patina naturally begins to develop. During this time, surrounding areas of the installation (Like concrete) could be subject to staining. However, once fully developed the patina will be stable and will not rub off onto hands or other materials. If looking to use raw material for interior applications, the patina can be chemically accelerated and sealed once the desired color is achieved.

Pre-GalvanizedM12Z-34 in Pre-Galvanized
Banker Wire offers wire mesh in two types of Pre-Galvanized wire; “Regular coating” and trademarked “Galfan”. The term pre-galvanized means that the wire already has the zinc coating applied to it prior to the manufacture of wire mesh. This is different than “Galv-after” where the galvanizing is done after manufacturing in a tank of molten zinc. Also known as “Hot Dip” galvanizing, the entire finished product emerges from the molten tank fully coated with a layer of zinc.
Regular coating “Pre-Galv” wire is carbon steel which has been coated with a very thin layer of Zinc during the wire drawing process. Pre-galv wire is only slightly more expensive than plain steel wire, but offers improved corrosion resistance. Pre-galv wire is a great base material if considering a wire mesh with a powder coated finish in an exterior application.
For exterior powder coated wire mesh applications, pre-galv wire should be specified so that there is a layer of zinc protecting the bare steel under the wire intersections. The powder coating process does not fully cover this area of the wire mesh, which is why the pre-galv wire is recommended.

Stainless Steel (A)/Brass (B)M12Z-34 in Stainless Steel (A)/Brass (B)
Combining stainless steel with brass wire within a sheet of woven wire mesh creates a striking blend of color that will change as the viewer changes their viewing angle. The contrast of silver and gold tones together can make a subtle statement to any interior space.
Brass wire is drawn bright and exhibits a gold like color. Brass has a subtle contrast woven together with Stainless Steel. The brass wire will tarnish over time as it is considered a "Living Finish". Care when handling the wire mesh when it is in the bare condition must be taken to avoid hand prints that will be difficult to remove. A lacquer topcoat should be considered as a way to preserve the bright finish.

Copper, Brass and Bronze are “Living Finishes”. The finish will oxidize in the presence of air, moisture, and even by natural oils from the skin. Introducing a clear topcoat like lacquer will create a barrier and prevent the material from tarnishing. If left bare, the color will continue to change at a rate and intensity unique to that of its surroundings and amount of handling. Learn more.

Secondary Finishes
Banker Wire has researched a number of secondary finish processes that work well with woven and welded wire meshes. Since different materials react to varying local environments, such as bare steel rusting in wet conditions, appropriate finishes for interior and exterior applications should be considered.
Many secondary finishes can be applied to help achieve the desired color, reflectivity, or corrosion resistance characteristics required.
Important Note Regarding Color
Please note that due to the limitations and relative inconsistencies of digital displays, the original and artificially colorized photography above is intended to only be a representation of the raw materials Banker Wire uses and is not a substitution for physical samples. Banker Wire manufactures all wire mesh in a bare mill finished condition. Please always confirm size, color, and finishes of wire mesh patterns with physical samples.
Powder Coating
Powder coating is a cost effective way to add an unlimited range of colors to wire mesh. Powder coating uses an electrostatic charge to attract a finley ground powder evenly across all surfaces of the wire mesh. The electrostatic charge holds the pigmented powder until it passes through an oven where it cures and adheres permanently to the wire mesh. After curing, the wire mesh has a colorful and durable coating that adds to the desired aesthetic of the project.
Decorative Plating for M12Z-34 wire mesh
Associated with Plain Steel Base
Decorative plating is an electrodeposition process where a thin layer of brass, nickel, chrome, or copper is deposited on the wire mesh surface in a tank-dipped procedure. A decorative antique plated finish can really bring out the texture of a woven wire mesh in ways that other coatings cannot. The thin layer of metal does not mask the detail of the wire mesh but rather highlights it. The antique plated finish process introduces a dark oxide layer over top of the bright plated alloy. Then, visual depth is removed by a human with an abrasive pad to get the desired effect on the high points of the wire mesh allowing the bright plated alloy to show through. A thin layer of lacquer is applied after plating to help preserve the finish from further tarnishing.
Maximum Dimensions: 42″x96″
Interior use only.
Special Considerations: The antique finishes undergo an abrasion process by hand to relieve the brighter alloy underneath the darker oxidized layer. The contrast between dark and bright alloy is unique to that of the various woven wire mesh patterns. The pictures above demonstrate how the different textures of the mesh patterns affect the same color finish. It should be noted that with any metal finish that is done by hand, a degree of variability will be inherent in the outcome. Samples of the finish will generally provide a good representation of color and detail however the brightness and darkness of the antique process may be different from job to job. This variability should be factored into the final design decision.

Designing with copper based alloys
US10A
The US10A finish physically removes the tarnish from the top layer of the bronze, brass or copper and seals it with a clear lacquer topcoat (For interior applications).
Special Considerations: US10A and US10B are not coatings. They are transformations of the existing base metal finish performed using a batch process. Deviations of color are inherent in these processes from job to job and no two metal finishers performing the same process are likely to arrive at the same color outcome. The time in solution, the base metal and the humidity in the area are just a few variables that prevent two separate outcomes to be the same. If consistency and a targeted color is what matters most to you, consider a powder coat that mimics the color instead like Prismatic Powders “Oil Rubbed Bronze”.
