Woven wire mesh is essentially a metal mesh screen. It comprises horizontal and vertical intersecting wires in a grid pattern. The individual wires can range in thickness, and the mesh openings vary in size, from small enough to filter particles to large enough to use in concrete patios.

To learn more about the basics of wire mesh, see answers to frequently asked questions below.
Wire mesh is made by weaving or welding intersecting metal wires. The horizontal and vertical wires are woven together on large industrial looms, most often resulting in a grid pattern with square openings called a plain weave. However, there's also hex mesh (aka chicken wire) that features hexagonal openings, as well as decorative variations.
Wire mesh is sometimes referred to as hardware cloth, metal mesh, wire fabric, or hardware mesh. The type with hexagonal openings is called chicken wire or hex mesh.
Wire mesh has a wide range of commercial (such as construction and building), industrial, agricultural, and residential uses. The most common applications involve filtration, ventilation, construction, fencing, landscaping, and pest control.
People often use the material at home for chimney caps, fireplace screens, gutter guards, foundation vents, soffit screens, gardening, craft papermaking, and food drying. It's also a top choice for decorative projects, like DIY cabinet doors, light fixtures, and infinite craft designs.
Wire mesh can be woven from various metals, including stainless steel, copper, bronze, brass, aluminum, and more. Steel mesh screens are available in two basic types of metal alloys, T-304 and T-316.
The material can also vary in terms of wire thickness (diameter), opening size, and mesh count (the number of openings per square inch). Some wire mesh is malleable and easy to cut, while other types are rigid. In addition to size and quantity, all these differences influence the cost.
Woven wire mesh is created with an industrial loom, which works by connecting horizontal and vertical wires with a one-over, one-under weave pattern. It’s a valuable material in a wide range of industries and applications due to its strength, durability, and ability to provide specific characteristics based on the weave pattern, wire diameter, and material used.
From chimney caps and craft papermaking to foundation vents and food drying, the mesh is a go-to for a variety of industries and DIYers.
With the welded variety, the intersecting wires are fused together with heat through a process called resistance welding. An electric current heats the metal while pressure is applied to bond the intersecting wires.
Welded stainless steel mesh is exceptionally strong, long-lasting, and resilient in various outdoor environments. It's often used in the construction and building sectors, but is also the perfect material for DIYers looking to build durable fencing, rodent proof their gardens and home, and more.
Galvanized wire mesh is a type of woven stainless steel mesh. Once the metal grid is created, the material goes through one of two galvanization processes. It can be dipped into molten zinc to form a strong, protective zinc-steel alloy over the surface.
The other option is electrolytic galvanizing (also called cold galvanizing). With this method, an organic zinc solvent is painted onto the mesh. When the solvent evaporates, zinc particles are left on the surface, which creates a chemical reaction to form the desired zinc-steel coating.
Galvanized hardware cloth is incredibly resistant to extreme temperatures, rust, and corrosion. The material is durable and somewhat stiff, but it can often be bent or manipulated by hand or with pliers. Its resilience and malleability make it a good choice for things like tomato cages, greenhouses, chicken coops, and spark arrestors.
Welded wire mesh is more rigid, so it's best for fences, automotive grills, building reinforcements, infill panels, gabions, and concrete driveways.

Galvanized stainless steel is an incredibly durable and resistant material. Pipes, nails, beams, plates, bars, rods, and other industrial products are often galvanized to ensure decades of strength and corrosion prevention.
Wire mesh plays a critical role in thousands of commercial and industrial applications. Galvanized screens, in particular, provide a lot of value, as they're adaptable, long-lasting, and reasonably priced.

A thick, robust outer layer of zinc is what makes galvanized hardware cloth so strong and resilient. How does it acquire this coating? It can be done in a couple of ways: hot-dipping and electrogalvanizing. Each process is outlined below.
1. The stainless steel is cleaned with a sodium hydroxide solution to remove dirt, debris, oil, and other residues.
2. An acidic solution is then used to remove any mill scale, rust, contaminants, and other surface impurities.
3. A zinc ammonium chloride cleaning agent (also known as a "flux") is applied to the surface to prevent oxidation. This solution remains on the steel, as it helps the zinc stick.
4. Next, the stainless steel is dipped into a vat of molten zinc (which has been liquified at an extremely high temperature).
5. The steel remains in the vat until it reaches the same temperature as the hot zinc.
6. After being removed from the vat, the stainless steel is rapidly cooled in a special tank.
Hot-dip galvanizing creates a physical and chemical bond between the steel and the zinc. This is what's called a zinc-steel alloy.
Unlike hot-dipping, electrogalvanizing (or electrolytic galvanizing) is a cold process. Zinc particles are used to create an organic solvent, which is applied to the steel surface.
This causes a reaction between the substances, resulting in a zinc-steel alloy. When the solvent evaporates, the zinc remains on the metal. Electrogalvanizing generally leaves a thinner zinc layer than the hot-dipping method.
When larger pieces of steel are galvanized, the zinc coating can often be seen with the naked eye. This is what's called "spangle," which has a crystalized, snowflake-like appearance. The crystallites are present with wire mesh screens, but they're usually too small to see.
Stainless steel can be galvanized either before or after it's fabricated into wire mesh. When galvanizing occurs first, the metal is drawn down the desired diameter. The individual metal wires are coated with zinc and then woven or welded into screens. Welding can burn the zinc layer off at the joints, in which case it may need to be galvanized again.
When fabrication comes first, pre-woven steel products are dipped into molten zinc or coated with a solvent. This is usually the more costly option, particularly if mesh products are custom ordered and then galvanized. However, it ensures the mesh screens retain their protective coating.
What is wire mesh used for after it's galvanized? Due to its notable durability and corrosion-resistance, the material is an important component of many industrial applications.
Galvanized stainless steel screens are used for:
- Agriculture and farming
- Archaeology
- Fencing, enclosures, and safety
- Gardening, greenhouses, and landscaping
- Gutter guards, soffit screens, and foundation vents
- HVAC applications
- Particle
- Pest-control
- Retention walls
- Roofing, ceilings, infill panels, drywall, and insulation
