Hardware cloth is a woven mesh product crafted by intertwining wire of various sizes to create a versatile metallic fabric. It's widely implemented in projects such as animal enclosures, fencing, sieves, and filtration screens. Differences in hardware cloth are determined by the wire type and gauge, finishing processes, and the technique for binding wire fibers at crossover points.
For hardware cloth, a higher gauge signifies a thinner wire. The typical wire gauges for this material include 16, 19, 23, 24, and 27, with gauge 16 being the thickest and largest. These gauges determine the robustness and applications of the mesh in different environments and usages.
Hardware cloth, also known as wire mesh or wire cloth, is constructed from a grid of parallel rows and columns of wire that intersect at right angles, forming square or rectangular openings. Although it may appear similar to expanded metal sheets or perforated metal, hardware cloth is manufactured using a unique wire fabricating process that differs significantly from those methods. This durable fencing and screening material can be made from a wide variety of wire diameters and mesh sizes, with smaller wire gauges and tighter mesh openings favored for applications requiring additional strength and protection. Hardware cloth is essential in multiple industries, including construction, agriculture, pest control, and HVAC, due to its versatility and adaptability.
A defining distinction between types of hardware cloth is how the wires are joined at the intersections. There are two major production methods: welding and weaving. The welding process uses specialized machines to fuse the wires at each crossing, creating a rigid, sturdy mesh that excels in applications requiring enhanced structural support. Alternatively, woven hardware cloth is produced through traditional weaving methods, in which wires are interlaced over and under each other, resulting in a flexible and resilient mesh with uniform openings. Understanding the difference between welded and woven hardware cloth is crucial for selecting the right type for specific projects, from garden fencing and animal enclosures to industrial filtration.
Hardware cloth can be produced from a wide range of metal wires, each offering distinct benefits depending on the intended usage. The most popular metal types are stainless steel, carbon steel, and galvanized steel. These metals provide exceptional durability, strength, and resistance to corrosion, making them ideal for both indoor and outdoor applications. In recent years, manufacturing advancements have introduced polymer-coated wires and alternative metal alloys for increased chemical resistance, further expanding the range of hardware cloth materials available for specialized environments.
Stainless steel hardware cloth is renowned for its long-lasting corrosion resistance and exceptional mechanical strength, making it an excellent choice for demanding environments where exposure to moisture or chemicals is common. Produced using grades like 304, 304L, 316, and 306L, stainless steel hardware cloth is available in both plain and twill weave configurations to suit different performance requirements.
Carbon steel hardware cloth is valued for its ductility and customizable strength properties, which are determined by varying its carbon content. This makes it ideal for applications requiring impact resistance and robust support. Hardware cloth can be manufactured from four main grades of carbon steel, each with its own physical characteristics:
Containing 0.05% to 0.25% carbon and up to 0.4% manganese, low carbon steel—also called mild steel—is highly malleable and often carburized for improved hardness. It is widely used in general-purpose mesh for screens, cages, and garden fencing.
Featuring a carbon content between 0.29% and 0.54% and manganese between 0.6% and 1.65%, medium carbon steel hardware cloth offers enhanced wear resistance and strength, making it suitable for heavy-duty barriers and machinery guards.
With 0.55% to 0.95% carbon and 0.3% to 0.9% manganese, high carbon steel produces exceptionally strong and durable hardware cloth used in applications with high tensile and impact demands, such as quarry and mining screens.
This grade contains 0.96% to 2.1% carbon, resulting in a strong but relatively brittle material best reserved for highly specialized uses.
Historically, galvanized steel hardware cloth has been the industry standard for fencing and protective barriers. Its zinc coating delivers powerful rust protection, extending the lifespan of the mesh in outdoor conditions. Many suppliers offer hot-dip galvanized, electro-galvanized, and vinyl-coated hardware cloth to provide even greater corrosion resistance tailored to user requirements.
Beyond these main metals, hardware cloth can be manufactured from an array of materials, including copper, aluminum, monel, and brass. Each metal offers unique performance benefits such as enhanced electrical conductivity, superior ductility, or specialized chemical resistance.
The image below features brass hardware cloth, appreciated for its pleasing appearance and excellent abrasion and wear resistance, composed of approximately 80% copper and 20% zinc. Brass mesh is often used in industrial filtration, decorative screens, and architectural mesh panels.
Welded wire hardware cloth is created by aligning horizontal and vertical wires to match the desired mesh opening, then passing the assembly through an automated welding machine. Each intersection is fused with electric resistance welding, forming a robust, permanent joint that adds immense rigidity and strength. Welded hardware cloth is preferred where structural integrity and security are priorities, such as in security fencing, animal enclosures, and building reinforcements. It is available in a selection of opening sizes, gauges, and metal finishes, supporting user requirements for pest exclusion, ventilation, and perimeter barriers.
Woven hardware cloth is manufactured by intertwining wires using specialized looms. This weaving method produces a mesh with uniform openings, excellent flexibility, and precise control over mesh size and wire gauge.

Manufacturing processes may be proprietary, but the primary goal is to achieve reliable mesh consistency and flexibility for a broad range of end uses.
The plain weave—also known as square weave—is the most common weaving pattern for hardware cloth. In this process, the warp (vertical) and weft (horizontal) wires alternate passing over and under each other, producing uniform square openings. This design is favored for fencing, aviaries, and general screening due to its balance of strength and versatility.
Each weft wire in a twilled weave pattern alternately passes above and below two successive warp wires, enabling the use of heavier gauge wire. This makes twilled weave mesh suitable for industrial filtration, heavy screening, and applications where extra durability is required.
Dutch weave hardware cloth involves combining a thicker warp wire with a finer weft wire to create very dense mesh with minimal open area. This pattern is commonly used for fine filtration, liquid-solid separation, and pressure-driven processes. Variations like reverse, twilled, and reverse twilled Dutch weave support specific industrial requirements.
The five heddle weave creates a series of parallel diagonal lines, increasing load capacity and impact resistance. Suitable for heavy-duty industrial screens and support mesh, this method ensures longevity in high-stress environments.
Besides these standard weaves, hardware cloth may also be manufactured using varied patterns such as oblong, multi-layer, cable, and spiral weaves to address unique requirements for ventilation, strength, or decorative appeal in custom mesh projects.
Knitted wire mesh forms hardware cloth with interconnected loops, resulting in a flexible and compressible mesh structure. Its honeycomb design offers durability, elasticity, and bi-directional stretch, making it practical for applications like air filtration systems, muffler packing, demisters, and EMI/RFI shielding. Knitted hardware cloth is available in round wire and flat ribbon forms with a variety of material options, and it is favored for uses demanding both flexibility and high strength in complex settings.
Crimped hardware cloth, produced from both ferrous and non-ferrous metals, features a range of crimping techniques—flat top, lock, double, and intermediate crimping—each designed to enhance mesh stability, increase rigidity, and support a variety of opening sizes. Crimped mesh is especially popular in industries such as mining, aggregate screening, architectural design, and security fencing, due to its ability to maintain shape under high-stress use and its customizable mesh size for specific separation or containment needs. Regular and heavy-duty options address everything from rodent-proofing to industrial sieves.
Flat top or pressed crimped hardware cloth produces a smooth mesh surface, ideal for conveying materials or architectural panels, by forming knuckles on the underside. Both warp and weft wires are crimped before weaving, guaranteeing consistent mesh alignment.
Lock crimping secures pre-crimped wires by pressing the knuckles firmly in place. The resulting mesh is highly rigid and resistant to movement—ideal for heavy-duty screening, guard panels, and partitions.
This crimping style incorporates crimps in both the warp and weft wires, producing a mesh with exceptional strength and dimensional stability. Double crimped mesh is widely chosen for gravel screening, livestock fencing, and structural reinforcement due to its tight, persistent pattern.
Available in single and double variations, intermediate crimping balances mesh strength and flexibility. In the single type, only the weft wire is pre-crimped, while the double version crimps both warp and weft wires—a popular option for screen decks, architectural panels, and industrial processes requiring tailored mesh solutions.
