A building worker is spraying shotcrete on welded wire mesh

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.

Welded wire fabric (WWF) for concrete slab reinforcement

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:

Imperial Size Metric Equivalent Weight Imperial Weight Metric 6x6 W1.4/W1.4 152x152 MW9.1/MW9.1 20 lb/100 sf 0.98 kg/m2 6x6 W2.1/W2.1 152x152 MW13.1/MW13.1 30 lb/100 sf 1.47 kg/m2 6x6 W2.9/W2.9 152x152 MW18.7/MW18.7 41 lb/100 sf 1.99 kg/m2 6x6 W4.0/W4.0 152x152 MW25.8/MW25.8 56 lb/100 sf 2.73 kg/m2 6x6 W5.4/W5.4 152x152 MW34.9/MW34.9 76 lb/100 sf 3.72 kg/m2 4x4 W1.4/W1.4 102x102 MW9.1/MW9.1 30 lb/100 sf 1.46 kg/m2 4x4 W2.1/W2.1 102x102 MW13.3/MW13.3 43 lb/100 sf 2.40 kg/m2 4x4 W2.9/W2.9 102x102 MW18.7/MW18.7 61 lb/100 sf 2.96 kg/m2 4x4 W4.0/W4.0 102x102 MW25.8/MW25.8 83 lb/100 sf 4.06 kg/m2 4x4 W5.4/W5.4 102x102 MW34.9/MW34.9 119 lb/100 sf 5.82 kg/m2

Electro galvanized welded wire mesh with square opening

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.

What Is 358 Fencing?

 

If you are doing research about high security fencing, you have probably asked yourself what is 358 fencing? That's because 358 mesh is very common in high security applications around the world.

While 358 mesh is relatively new in Canada, Rite-Way Fencing is one of the few fence companies that are actively growing our product line in this area, and we're happy to tell you what you need to know.

What Is 358 Mesh?

358 Mesh is a welded mesh panel that is used in fencing, combined with a steel support structure. It is considered one of the best choices for high security fencing around the world, because it is hard to cut and hard to climb, but it still allows enough visibility through the fence. All of these are important factors in designing a high security fencing system.

Why Is It Called 358 Mesh?

Many people wonder why 358 mesh is named that, but the answer is actually very simple.

358 Mesh is called that because of the dimensions and materials it is manufactured with. Apertures are 3 inches long and 0.5 inches high, and the panels are manufactured from 8 gauge wire. Similarly, you can choose 356 mesh and mesh in some parts of the world.

What Finishes Do 358 Mesh Come In?

358 Mesh panels are almost always galvanized, but in some cases, they can be zincalum coated instead, or powder coated after galvanizing.

While most people in Canada are familiar with galvanizing and powder coating, zincalum is a lot less common here. This alloy of zinc and aluminim is applied the same way zinc is in a hot dip galvanizing setting, but offers far superior corrosion resistance.

Where to Get 358 Mesh Panels

Many of the worlds best fence manufacturers offer 358 fencing systems. They may have different posts and other structural design changes, but they all offer superior security for customers who want to invest in the best possible perimeter security.

One important thing to remember, however, is that while there are many manfacturers and suppliers for high security fencing, it takes a special contractor to properly install it. These fences demand accuracy in three dimensions, and if your contractor isn't experienced, you might not get the best result.

Rite-Way Fencing is an experienced fence contractor, and we have installed every high security fence system you can think of (and several more besides!) We'd love to talk to you about your project, so get in touch with our team!
