Stainless Steel Woven Wire Mesh & Screen Overview
A Stainless Steel Woven Wire Mesh, Wire Cloth & Screen Overview
Wire mesh is a fabric-like material used in countless industrial and commercial applications. Its versatility is due in part to its availability in a broad range of variations, which differ in regard to opening size, wire diameter, material, and construction.
Wire mesh materials can be categorized into two main classifications based on construction: woven or welded. The following page provides an overview of woven wire mesh, outlining what it is, key features and benefits, how it differs from welded wire mesh, and typical applications.
What Is Woven Wire Mesh?
Woven wire mesh—also sometimes referred to as woven wire cloth—is created by weaving wire strands in an over-under or under-over method to form different patterns with varying specifications. Some of the most common weave patterns employed include:
Plain/square weave
Rectangular weave
Plain Dutch weave
Twilled Dutch weave
Intercrimp weave
The weave pattern of mesh significantly influences what use cases for which it is suited. For example, plain square weaves are ideal for use in general-purpose applications, while Dutch weaves are more appropriate for use in air and water filtering applications.
In addition to weave, woven wire mesh varies in regard to size and material. It is available with openings ranging from a few microns to 4 inches and metals such as aluminum, brass, bronze, copper, Monel, and (most commonly) stainless steel.
Benefits of Woven Wire Mesh
When used in industrial and commercial applications, woven wire mesh offers a number of advantages, including:
Strength: The interwoven and clinched design of woven wire mesh results in a durable and reliable material that retains its structural integrity during use even when subjected to impact and other stresses.
Ventilation and visibility: The numerous openings in woven wire mesh allow light, air, and sound to pass through relatively unobstructed, resulting in better visibility, circulation and ventilation, and acoustics in the facility.
Safety and security: The open design allows employees to maintain a direct line of sight throughout the facility, enabling them to act accordingly in the event of an emergency. For example, if there is a fire, they can stop any equipment and spray extinguishing fluid through the mesh. In addition to facilitating visibility, woven wire mesh also protects employees and equipment from large debris that flies outward or inward, respectively, without sacrificing any of the above qualities.
Easy cleaning and maintenance: Woven wire mesh is easy to clean and maintain, resulting in smaller time and labor costs for such operations.
Low investment cost: Many manufacturers have optimized the manufacture of woven wire mesh to decrease waste and increase production efficiency, which translates to a lower price point for customers.
Broad availability and customizability: As indicated above, woven wire mesh comes in many patterns, materials, and sizes. While there is an extensive selection of standard options available, some manufacturers offer custom solutions to customers with highly specific or unique needs.
Woven vs. Welded Wire Mesh
Wire mesh comes in both woven and welded variations, both of which offer unique advantages that make them suitable for different industrial applications. For example:
Woven wire mesh has a much wider range of possible specifications compared to welded wire mesh, resulting in applications ranging from micronic filtering capabilities using fine woven mesh to fencing and security screens using coarse woven mesh. It is also more flexible, making it ideal for use with parts and products with unusual or irregular contours.
Welded wire mesh is stronger and more durable than woven wire mesh, making it suitable for use for protective or barrier purposes. As the individual wire strands are welded in place, the mesh as a whole is more rigid and uniform, both qualities which suit this type of mesh for use in parts and products with strict dimensional tolerances.
Common Applications for Woven Wire Mesh
Woven wire mesh is highly versatile. It sees uses in a wide range of industrial applications, such as the following:
Architectural elements (e.g., infill panels)
Baskets (e.g., fry baskets)
Cages (e.g., livestock and security cages)
Fencing
Filtration and separation components (e.g., drain filters)
Grills and grates
Handrails and safety guards
Medical centrifuge screens
Racks (e.g., drying racks)
RFI and EMI shielding
Screens (e.g., fireplace, insect, security, and splatter screens)
Shelving and stands
Ventilation fan screens

Welded Steel Reinforcing Mesh for Concrete Construction
Concrete reinforcing mesh is a Welded Mesh Sheet designed in different sizes and materials. Welded Reinforcement Mesh for construction is regularly used for concrete slab construction, for roadways, in curved structures in domes and concrete pipes. It help enhance the strength and reduce the shrinkage of the concrete structures.
Benefits of Using Welded Wire Mesh used in concrete reinforcing:
Concrete is an excellent choice for steel structures, cladding systems and floor slabs on grade.
Although concrete is an excellent building material and is extremely strong in compression, it has one limitation - concrete is weak in tension. By combining concrete with material that is strong in tension, a composite building material greatly reinforced is formed. The reinforcement can minimize shrinkage cracking in the surface of the concrete. This type of steel reinforcement used in concrete is welded wire mesh (WWM) or welded wire fabric (WWF).
Using reinforcing welded mesh also saves cost, time and labor compared with traditional tied rebar reinforcing.
Structure of Welded Reinforcing Mesh:
Welded Wire Mesh for Reinforcement can be made of ribbed bar or steel wire welded together.
Welded wire mesh panels made of ribbed steel bars bonded via spot welding are popularly used for slab and wall constructions. The ribbed steel rod used can improve bonding to the concrete and minimize any concrete cracking that may occur as a result of concrete shrinkage. This feature enables the ribbed steel weld mesh widely used as building materials for block slab structure reinforcing, and hollowed slabs reinforcement, building wall reinforcement and support wall reinforcement. In practical uses, it is commonly used with bar chairs as supports.
The popular panel size of wire reinforcing mesh is 6m length ×2.4m width. It comes in a variety of bar thickness and the internal square or rectangular sizes. Common square mesh is either 200×200mm or 100×100mm.

Wire Mesh Welding & Soldering Services
Wire mesh is a prefabricated grid of interlocked metal strands that are spaced at even intervals to create a symmetrical pattern of spaces. It typically consists of two layers of parallel metal strands, with the second layer perpendicular to the first, forming a grid. The individual strands are generally welded or woven together to ensure the material’s overall stability. Afterward, the material can then be subjected to further welding and soldering operations to create product components and complete product assemblies.
The welding and soldering processes rely on similar elements—i.e., high heat and filler materials—to connect components. However, the end result of each process is different. Welding is used to form a strong and durable joint between two or more components of the same material. Soldering also joins metal components together, but the bond formed is not as strong as a welded bond. Both processes are used to manufacture parts and products from wire mesh.
Materials for Wire Mesh Welding and Soldering Operations
Wire mesh comes in a variety of metals, all of which can be welded and soldered to form various components and assemblies. Some of the metals that are commonly used for wire mesh are:
Carbon steel – Carbon steel is the least expensive wire mesh option. It is an iron alloy with levels of carbon, molybdenum, and other metals to enhance particular features. Due to its high iron content, it is more prone to degradation than other steel blends. When exposed to oxygen and humidity, it will rust, corrode, and pit, so it is best suited for indoor applications where it will be exposed to little or no moisture.
Stainless steel – Stainless steel is an iron ore with a minimum chromium content of 10.5% by weight and sometimes molybdenum and nickel. The presence of chromium in the material creates a corrosion-resistant oxidized surface layer. While it is more expensive than other steel alloys, it exhibits similar strength and greater corrosion resistance, which makes it a reliable long-term option, especially for outdoor settings or applications where moisture and humidity may be present.
Galvanized steel – Galvanized steel is also corrosion-resistant. However, unlike stainless steel, which has a built-in chromium oxide covering, it has been treated with a layer of protective zinc. Zinc is more durable and corrosion-resistant than steel, which allows for additional protection from the elements. Galvanized steel mesh is not as expensive as stainless steel and can be used in many of the same applications.
In addition to the base wire mesh material, wire mesh welding and soldering operations require filler materials. These materials are melted and applied to wire mesh to connect separate pieces. As such, they must exhibit melting points that are attainable and bond with the wire mesh once they solidify. Once a wire mesh assembly is fully welded or soldered, coatings and finishes can be added to improve its functional or aesthetic surface qualities.
The Wire Mesh Welding and Soldering Process
The process of welding and soldering wire mesh to manufacture product components and assemblies is similar to the process of welding and soldering metal strands to produce wire mesh. Both processes employ heat, pressure, and filler material to form welded or soldered joints. The main difference between them is that the end result of wire mesh welding and soldering operations is a usable part or product rather than a raw material.
Welding and soldering are generally used in conjunction with other fabrication operations — e.g., punching, shearing, cutting, notching, slitting, and seaming — to manufacture various wire mesh components and assemblies. For example, the material can be mounted and welded to a frame to create a basket or rolled and welded into a cylinder. Other examples of welded or soldered wire mesh parts and products include:
Architectural elements
Cages
Dividers, partitions, and screens
Fencing
Filters and separators
Grills and grates
Shelving
Advantages of Wire Mesh Welding and Soldering
Wire mesh offers a number of benefits when used in welding and soldering operations, including in regard to the following:
Wire mesh offers an aesthetically pleasing design that makes it suitable for use in decorative applications.
Wire mesh is available in several types of metals, which allows manufacturers to choose the material that best accommodates the requirements and restrictions of the intended application.
Cost – Compared to other fabrication materials used in the same applications, wire mesh offers greater durability and reliability and easier cleaning and maintenance requirements, both of which result in lower operational costs over time.
