Fencing for residential areas and gardens; securing agricultural and livestock areas; fencing off construction sites, industrial and sports facilities; reinforcement of floor screeds and roofing slabs. These are just some of the possible uses of electrowelded wire mesh, a type of mesh that is essential in building, industrial, and agricultural sectors.
Here we analyse its particular characteristics and the contexts in which it is most commonly used, with the aim of providing you with the necessary information for an informed purchase.
Electrowelded wire mesh consists of steel wires welded together at the points of intersection. The welding guarantees a high level of resistance and security.
This type of mesh is more rigid than loose mesh, which makes it more suitable for installation on flat terrain, and in combination with a concrete wall. In the case of uneven terrain and major differences in height, it is better to opt for a loose mesh net, which is more flexible.
The diameter of the wires and the type of mesh determine the degree of strength and resistance of the welded mesh. The meshes are typically square or rectangular in shape, of different sizes (50 x 50mm, 50 x 25mm, 50 x 75mm, 25 x 25mm) and made with linear or moulded wires. Some types of nets also have additional reinforcing wires and bands to provide greater strength and resistance.
The most commonly used materials and their coatings
Electrowelded wire mesh consists of steel wires with zinc and PVC coatings. The quality of the wire coating has a significant impact on the strength and durability of the mesh, which is why Cavatorta has a Research and Development department that has developed exclusive technologies for coating wires over the years, with the aim of offering high performance in different contexts of use. Here, we briefly describe the different types of coating we have developed.
The coating obtained with a zinc (95%) and aluminium (5%) alloy, gives the final product an excellent corrosion resistance and an effective cathodic protection after cuts and abrasions.
A heavy galvanising process developed by Cavatorta. The main advantage with material coated in this way is that the coating never cracks even when bent 180°. Every product treated with this process is guaranteed to be corrosion free for 10 years.
An exclusive PVC coating process by sintering, developed by Cavatorta to give the base wire or the galvanized wire mesh excellent characteristics of durability and corrosion resistance.
Seaplax Process is a combination of Galvafort Process and Galvaplax Process and offers a further advantage given by the special formulation of the PVC coating; in fact, the protection obtained can withstand constant immersion in salt water and corrosive environments, even in extreme temperature changes.
Electrowelded mesh in panels and mesh in rolls
Electrowelded wire mesh is sold in rolls or panels. Nets in rolls are characterised by smaller wire diameters, so that they can be wound around themselves. In our catalogue you will find electrowelded nets in rolls made with wires of different diameters, designed to best meet the specific needs of each context of use.
Electrowelded wire mesh in panels, on the other hand, is characterised by larger wire diameters and a high degree of strength.
Both types (rolls and panels) can be characterised by differentiated meshes, reinforcing wires, and anti-removal spikes in contexts where they need to guarantee greater solidity and safety.
Contexts of use
Welded mesh is used in a wide range of contexts, from residential to industrial to agricultural applications. This product is an excellent choice for fencing and securing agricultural and livestock areas, sports facilities, temporary construction sites, residential zones and industrial areas.
In our catalogue you will find lighter configurations that are suitable for common fences and high-security nets with very tight meshes, anti-skimming spikes and cathodic protection against cuts and abrasions, designed to protect against any intrusion attempt.
