What is Galvanized Woven Wire Mesh and Why Do We Use Them?

Galvanizing can be done before or after wire fabrication, for both woven and welded wire mesh types. If the individual wires themselves are galvanized before the woven or welded wire mesh, this is called "galvanizing before woven or welded material". This is usually the least expensive option (depending on the mesh or opening size), especially when custom fabrication is required.

"After galvanizing" woven or welded wire mesh, as the name implies, is done after fabrication. Typically, the mesh is made of carbon steel or plain steel and placed in a galvanizing bath to produce the "after galvanizing" woven or welded mesh specification. Typically, this option is the most costly of the two, depending on its availability, but the process offers the advantage of higher corrosion resistance. This reduced risk of corrosion is more likely to be seen at the joints of the "post-galvanized" welded wire mesh specification.

Wire Mesh After Galvanizing: Welded or Woven

Manufacturing post-galvanized wire mesh has advantages over manufacturing pre-galvanized wire mesh. The reason for this lies in the way it is manufactured. Post-galvanized wire mesh can be welded or woven. After welding or weaving is completed, the wire mesh is immersed in a molten zinc bath. The zinc bonds to the wire surface, completely sealing and preventing rust and corrosion.

Caution

When galvanizing prior to fabricating welded wire mesh, the zinc coating at the weld point can be damaged. It can be burned off, leaving the wire unprotected. And these intersecting areas tend to retain moisture longer than single strands of wire.

Woven wire mesh, especially in lighter gauges like chicken wire hexagonal mesh, also has its weaknesses. The twisted areas of the mesh tend to hold moisture, causing them to rust. Immersed in a zinc bath, these wire meshes will last a long time, even in corrosive environments.

The Importance of Releasing Coils of Galvanized Wire Mesh After Buying Galvanized After Wire (GAW) Mesh

Lasts a long time

Withstands rough use

Has an extra thick zinc coating

Thoroughly protects joints from rust and corrosion

More useful in areas where galvanized wire mesh would have decayed before

When you want to use galvanized wire mesh in your project, be sure to consider the advantages that GAW products offer. Consider the cost and labor involved in replacing GBW mesh that rusts quickly. Invest in a quality product.

Benefits of Galvanized Wire Mesh

One of the main advantages of galvanized wire mesh, especially the galvanized welded option, is the much larger range of wire diameters and opening sizes available. For example, most wire mesh suppliers tend to keep openings in 4 x 4, 2 x 2, 1 x 1, and ½ x ½ inches as well as a wide range of wire sizes.

Galvanized wire mesh is popular with industrial users because of its corrosion resistance and relative affordability. Galvanized wire mesh is usually recommended for areas of a project that require fairly large opening sizes. It is worth keeping in mind that galvanizing a relatively fine mesh may clog openings, which means it is useless for several types of applications. Because of this, a 10 x 10 or finer mesh is often manufactured as a form of wire mesh prior to galvanizing.

Woven and welded wire mesh may look similar to the untrained eye, but while they share some characteristics, the materials are distinctly different.

What is Woven Wire Mesh?

Woven wire mesh is a metal grid with intersecting vertical (warp) and horizontal (weft) wires that create square-shaped (or sometimes hexagonal) openings. Since the wires only intersect rather than being welded or otherwise fixed together, this type of mesh is typically flexible and easy to manipulate. Though woven mesh is often pliant, it can be more rigid when made with thicker wires.

How is woven mesh made?

The mesh is typically made using an industrial loom (sometimes called a weaving machine). Wires are wrapped around a warp beam, then placed into a heddle frame. This separates the warp wires so they can pass through another set of weft wires and create a grid pattern of a specified size.

What is it used for?

A wide range of applications call for woven wire mesh. This is especially true when it comes to home improvement and DIY projects. The material is a go-to for everything from gardening, composting, and craft papermaking to pest control, insect screens, and food drying. Artistic DIYers can even use this bendable mesh to create decorative sculptures.

In the industrial sector, it's often used for filtration, screen printing, and particle analysis.

What is Welded Wire Mesh?

Welded wire mesh is a stainless steel grid with intersections fused together with heat. This material is not malleable but rather rigid and notably strong, maintaining its structure under heavy pressure.

How is welded mesh made?

Welded wire mesh is made by first feeding opposing (warp and weft) wire spools through a special welding loom. The machine lays the horizontal wires over the vertical wires to create a grid, then it applies heat to the intersections to fuse the crossing wires together.

What is it used for?

Unlike woven wire mesh, the welding process calls for thicker metal wires. This sturdy, inflexible material is ideal for fencing, chicken coops, and animal enclosures. It can also be used for soffit screens, foundation vents, chimney caps, gabions, trellises, and automotive grills.

In the engineering and construction sectors, stainless steel welded mesh is used for infill panels, landslide mitigation, and highway reinforcement.

Which Wire Mesh is Best, Woven or Welded?

Welded wire mesh is constructed with thicker wires and is available in larger opening sizes. This material can be used for structural purposes when projects call for durable metal grids.

Woven wire mesh, on the other hand, is available in much finer weaves (including many decorative styles), which makes it useful for cabinet inserts, insect screens, and more. 

If you need a large, rigid metal mesh panel with reliable strength, go with welded mesh. If you need something with much smaller openings or that can be manipulated into different shapes, woven mesh is a better choice.
