Welded wire mesh
Welded wire mesh, or welded wire fabric, or "welded mesh" 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 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. 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 |
