WELDED MESH FENCING / WIRE MESH FENCING
People are often confused when it comes to Welded Mesh Fencing so we put together this guide to help you understand a little more about Welded Mesh Fencing and it’s various uses.
Firstly to the name (or names). Welded Mesh Fencing / Wire Mesh Fencing / Paladin Fencing / 3D Fencing / 2D Fencing / V Mesh Fencing / Weldmesh are but a few of the differing names it’s often called. Most of the time in the Irish market these names refer to the type of green premiter fencing we often see around sports grounds, office buildings and schools.
To the untrained eye most Welded Mesh Fencing looks the same but there are some subtle but noticeable differences. Let’s separate these differences into to main categories, construction and design.
The two most common types of construction used in mesh fencing are Electro Galvanised Wire Mesh and Hot Dip Galvanised Welded Mesh. With Electro Galvanised Wire Mesh the fence panels are constructed of pre Electro Galvanised Steel Wire which then is placed in a jig and Electro Welded to form a single fence panel. After this it is sent to have it’s finish coat applied, which is most often powder coating.
The Welded Mesh Fencing supplied by Daniel Whelan Engineering Ltd is all Hot Dip Galvanised. Steel wire is cut into desired lengths and if it is for 3D welded Mesh Fencing it’s then profile formed into shape. Once this is complete all of the materials are placed in a jig and Electro Welded to form a fence panel. The entire fence panel is then Hot Dip Galvanised in molten zinc (at 450°C) to form a protective layer. Once the panel is cooled after galvanised it is then sent to have it’s power coat applied.
The construction two process do provide similar visual results but there are some important differences. Hot Dip Galvanised Welded Mesh Fencing panels are more expensive to produce but the end result if a superior product. When pre galvanised wire is Electro Welded the joint is prone to corrosion over time as the welding process remove the galvanisation at the location of the weld. When the panel is electro welded prior to galvanisation there is no denigration of the protective Zinc layer.
Daniel Whelan Engineering Limited only use the Hot Dip Galvanised method of construction for our fence panels so we can provide our clients with a superior product.
Yet again we can separate our fencing into two main types 2D & 3D. The best way to explain the differences is to view both welded mesh fencing panels side on.
As you can see the 3D Mesh Fencing panel has crimping at intervals along it’s axis which allow the panel to be manufactured using less materials while still achieving a high level of strength and rigidity. 3D Welded Mesh Fencing is an attractive and cost effective solution for perimeter fencing and other similar applications. Daniel Whelan Engineeirng Ltd can supply 3D Welded mesh fencing in panels of various sizes, to a maximum height of 2430mm and width of 3006mm, you can get more information on specification and sizes here.
2D Welded Mesh Fencing is often referred to as double wire fencing due to having horizontal wires on both sides of the panels. While the 2D / double wire construction does make these panels slightly more expensive there are substantial security and usage benefits. We supply both 8-6-8 and 6-5-6 2D Welded Mesh Fencing. Their design and construction is the same only that the 8-6-8 provides a higher level of strength and security do to the thicker steel wire used in it’s manufacturing. The double wire panel 8-6-8 (mesh size 100 x 200 mm) is the professional solution for setting up ball-stop fences up to 8 meters high.
While this is not exhaustive list to every detail about Welded Mesh Fencing it should certainly give you a good general idea about it. If you have any questions or comments please feel free to contact us
