Welded wire mesh, or welded wire fabric, or "weldmesh" is an electric fusion welded prefabricated joined grid consisting of a series of parallel longitudinal wires with accurate spacing welded to cross wires at the required spacing.

Machines are used to produce the mesh with precise dimensional control. The product can result in considerable savings in time, labour and money.

Uses of welded wire mesh

[

The welded wire mesh is a metal wire screen that is made up of low carbon steel wire or stainless steel wire. It is available in various sizes and shapes. It is widely used in agricultural, industrial, transportation, horticultural and food procuring sectors. It is also used in mines, gardening, machine protection and other decorations.

Weld mesh is the term given to the kind of barrier fencing that is manufactured in square, rectangular or rhombus mesh from steel wire, welded at each intersection.

Welded wire fabric (WWF) is also sometimes used in reinforced concrete, notably for slabs.

Types of welded wire mesh

There are several types of welded wire mesh which can be categorized according to their structure, use, and characteristics.

This type of mesh is a square grid of uniformly placed wires, welded at all intersections, and meeting the requirements of ASTM A185 and A497 or other standards.[1] The sizes are specified by combining the spacing, in inches or mm, and the wire cross section area in hundredths of square inches or mm2. The common sizes are in the following table:

This type of welded wire mesh is designed for building fencing and in other infrastructural purposes. It is a corrosion resistant wire mesh that is largely used in structural building. It is also available in different forms like rolls and panels for industrial uses.

Hot dipped galvanized welded mesh

]

This type of mesh wire is generally made up of plain steel wire. At the time of processing it goes through a hot zinc covering process. This type of welded mesh ware with square opening is ideal for animal cage structuring, fabricating the wire boxes, grilling, partition making, grating purposes and machine protection fencing.

PVC coated welded mesh

[

PVC coated welded mesh with plastic covering is constructed with galvanized iron wire of high quality. It has PVC powder covering that is processed by an automatic machine. The smooth plastic coating on this corrosion protective wire is attached with a strong adhesive which make increases durability of the wire. It is used in fencing residential and official properties like gardens, parks, building etc. The PVC coated welded mesh which is available as both rolls and panels, is also available in different colors like white, black, green etc.

Welded stainless steel mesh

This kind of welded mesh wire is basically used in industrial fencing purposes. It is made up of stainless steel that has high strength and integrity. This corrosion resistance meshed wire is long lasting and is widely used in transportation, agricultural, mining, horticulture, entertainment and other service sectors.

When cement is poured, it needs reinforcement from galvanized wire mesh in order to take shape. In addition to helping form platforms, roadways, and structures, this helps prevent cracking and architectural failure.

Steel mesh can be galvanized in one of two ways. The first method is referred to as hot-dipping, and it involves dipping the metal into liquified molten zinc. This results in the formation of a zinc-steel alloy, which coats the material's surface with a protective layer.

The other technique is electrolytic galvanizing (also called electrogalvanizing or cold galvanizing). With this method, an organic zinc solvent is applied to the steel, which evaporates and leaves a thin layer of zinc-steel particulates on the surface.

Durable galvanized metal is a go-to for the construction industry. However, how long will it last in concrete, and will it rust? Ahead, answers to these questions, along with insight into the benefits of this ultra-strong, versatile material.

How Long Do Galvanized Wire Mesh Panels Last in Concrete?

Galvanized wire mesh panels can last several decades&#;potentially over a century&#;before they begin to corrode in concrete. The exceptionally durable, resilient material will also resist rust for 50 to 75 years.

The unique durability and environmental resistance of galvanized steel make it ideal for buildings and infrastructure, especially in concrete applications. An accumulation of rust and corrosion can eventually lead to structural collapse, but the concrete will show signs of wear prior to this scenario.

Rebar vs. Galvanized Mesh for Concrete

As noted, concrete needs reinforcement to ensure it takes the intended shape and holds up for decades. Rebar (short for reinforcing bar) is often embedded into cement before it hardens. While these steel bars have long been the standard, galvanized welded and woven wire may be a better alternative.

Galvanized stainless steel mesh is:

• Consistently sized and spaced

• Highly durable with exceptional tensile strength

• Preassembled for convenience

• Relatively easy to lay in the proper position

• Resistant to rust and corrosion for decades

Galvanized steel mesh is also often more affordable than traditional rebar, helping developers and builders save substantial money. For roadways, vehicle storage, and large buildings, a combination of the two materials may be necessary for dependable reinforcement against the continuous weight.
