Galvanized Wire Mesh

Today, galvanized wire mesh is used in countless applications. As a result of galvanization, customers receive better value from products with longer lifespans and less upkeep.

Methods for Creating Galvanized Wire Mesh

The strength and resilience of galvanized wire mesh are due to a thick, substantial zinc outer layer. There are two methods for coating: hot- dipping and electro-galvanizing. Hot-dipping, or putting the wire mesh through a bath of molten zinc-based alloys, is the typical procedure for galvanizing metals. Electro-galvanizing, in which the zinc alloy and steel mesh are joined by opposing electrical charges, can be utilized for protective coatings that are lower in weight. Below is a description of each process.

Hot-Dipping

Steel and zinc are joined together chemically and physically during hot-dip galvanizing, or hot-dipping. The process is explained below.

1. To remove dirt, debris, oil, and other leftovers, the stainless steel is washed using a sodium hydroxide solution.
2. Any mill scale, rust, pollutants, and other surface impurities are cleaned using an acidic solution.
3. To stop oxidation, the surface is coated with a cleaning substance called a "flux" that contains zinc ammonium chloride. This mixture stays on the steel because it makes the zinc adhere.
4. The stainless steel is then submerged in molten zinc (liquified at an extremely high temperature).
5. Once the steel reaches the same temperature as the hot zinc, it is left in the vat.
6. The stainless steel is swiftly cooled in a special tank after being taken from the vat.

Electro-Galvanizing

As opposed to hot-dipping, electro-galvanizing (also known as electrolytic-galvanizing) is a cold procedure. An organic solvent is made from zinc particles which is subsequently applied to the steel’s surface. The chemicals react with one another, to create a zinc-steel alloy. The zinc stays on the metal after the solvent evaporates. In comparison to hot-dipping, electro-galvanizing typically leaves a thinner zinc coating.

Spangles

Larger steel objects that have been galvanized frequently have a visible zinc coating. This visible layer has a crystallized, snowflake-like appearance and is referred to as a "spangle." Wire mesh screens can contain crystallites, but they are typically too small to notice.

Meshing Size

Given mesh parameters may vary by maker and product type. One way to identify a certain mesh is by the opening size, like 1-½” mesh. However, even typical chicken wire from the same manufacturer might have openings ranging in size. Mesh size is better expressed as the number of spaces within a square inch because the opening between wires will vary based on the product and wire diameter. This range in opening size is done to meet the demands of various clients. For example, the openings in fencing might be 2x4, 2x2, or 4. For example, a typical window screen will have a mesh size of about 18x16 and be designed to keep out insects as small as gnats. Accordingly, there are 16 apertures in a 1-inch vertical measurement and 18 openings in a 1-inch horizontal measurement. Numerous manufacturers across the sector may standardize sizes and apertures. For example, a product requiring No. 2 mesh will have a 0.42” hole with 0.08” diameter wire. This mesh is also known as each area having 70.5 percent unoccupied space.

Benefits of Galvanized Wire Mesh

A more affordable alternative to panels or board fences is galvanized wire mesh. It comes in rolls that can be split into desired lengths or sizes, with the leftovers being rerolled for simple storage. Most meshes can be easily cut to fit any needed dimensions using wire cutters or power-cutting equipment like grinding wheels. Various fasteners, such as nails, screws, clips, and smaller bits of wire, can hold them in place. Compared to other mesh materials, galvanized steel mesh is much stronger and more resilient. Compared to corrodible materials that need to be changed regularly, galvanized wire mesh costs less in the long run. It can be bent back into shape and offers increased resistance to impacts thanks to its flexibility. Greater security and tranquillity are also provided. Mesh is available in so many variations that it can support the aesthetics of other property components. Large rolls can be bought to provide consistency across a property or large-scale project. It can be painted, bent, and sculpted to fit various areas, angles, and curves.

Industrial Applications of Galvanized Wire Mesh

The material plays a significant role in numerous industrial applications due to its exceptional durability and resistance to corrosion. Uses for galvanized stainless steel screens include:

• farming and agriculture
• archaeology
• safety enclosures and fencing
• landscaping, gardening, and greenhouses
• soffit screens, gutter guards, and foundation vents
• applications for HVAC
• substance screening
• pest management
• retention walls
• insulation, drywall, infill panels, roofing, and ceilings
