In welded mesh the weft and warp wires are mechanically welded where they intersect, yielding great strength and keeping the mesh size precise. This type of mesh may be preferable in a lot of cases, as it can combine a relatively large mesh size with relatively thin wire. An important property of welded mesh is its high permeability. In most cases it is hot dip galvanized after fabrication. The apertures in welded mesh can be square or rectangular, the mesh sizes range from 5mm to 50mm, and the wire diameters from 0.50mm to 2.70mm.
We can supply spot-welded mesh in the following materials:
• Welded stainless steel
• Welded uncoated iron wire
• Welded galvanized iron wire
• Welded uncoated iron wire, hot dip galvanized
The last three types can also be coated with PVC or epoxy if required.
Spot-welded mesh is used e.g. in horticulture, agriculture and the building industry. Dinxperlo regularly produces spot-welded mesh for animal cages and plant support netting. We supply plant support netting in two versions, plastified and galvanized. Mesh for animal cages is made mainly of stainless steel, and can be supplied on the roll or in panels.
Some materials can be specially treated to improve quality. The options include:
Galvanising: applying a protective layer using a galvanising process:
• This protects corrodible materials (e.g. iron) against atmospheric corrosion; the most common product is galvanized iron mesh.
Plastification: applying a coating of PVC material:
• This protects the woven wire product against atmospheric corrosion.
• It brightens up the appearance with different colours.
Epoxy-coating: applying a coating of epoxy material:
• The same improvements as plastification.
Annealing: heating the material until it starts to glow:
• This removes the hardness in the product caused by the weaving process, making the material more deformable.
