What We Do
Welded Mesh Panel and Grill Manufacturing
We manufacture mesh suitable for a variety of purposes including recreation areas, restricted areas, high security areas and machinery guarding. Read more »
Specialist wire components are made on our 2D and 3D CNC wire forming machines. Read more
Wire Cutting and Straightening
NZ Wire & Mesh have 5 dedicated wire straightening machines which can straighten and cut wire pieces to almost any length. Read more
Welded mesh design and manufacture
NZ Wire & Mesh Ltd are specialist manufacturers of custom-designed welded mesh panels. We will work to standard specifications or individual specifications provided by customers for private work and/or by designers, architects and engineers. We have the ability to fabricate almost any mesh gauge, pitch (aperture) and size in raw steel, pre-galvanised steel and stainless steel.
Our set-up times and manufacturing rate are designed to work within a very short turn-around time to produce multiples of welded mesh products and have them ready for despatch directly to the customer.
The mesh itself is manufactured here at our factory in New Zealand on a dedicated CNC Ideal GAM116 automated mesh making machine. We have direct control over weld temperature, duration and pressure to ensure that every single weld point is the strongest it can be and meets AS/NZS 1554.
Our facilities also include bending, rolling and folding panels to make a finished product such as guarding assemblies, balustrade inserts, framed panels, rock-baskets and gabions.
Wire straightening and cutting
Our cutting and straightening department provides a rapid and accurate service for buyers requiring specific lengths of straight wire. Typically we supply this service to manufacturing companies looking to add value to the wire as part of an end-product component such as pest traps and calendar hanger wire.
Buyers can choose to supply their own wire or choose from our standard stock.
Powder and thermoplastic coating
Tell me about Powder Coating
Powder coating is a system of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form.
The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a “skin”. The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.
We have in-house powder and plastic coating facilities. This service is also available for goods and materials made elsewhere such as aluminium extrusions.
What are the advantages of using powder coating instead of other coating treatments?
- Powder coatings emit near zero volatile organic compounds (VOC).
- Powder coatings can produce much thicker coatings than conventional liquid coatings without running or sagging.
- Powder coated items generally have fewer appearance differences between horizontally coated surfaces and vertically coated surfaces than liquid coated items.
- The wide range of speciality effects are easily accomplished using powder coatings that would be impossible to achieve with other coating processes.
What about Thermoplastic Coating? What is the difference?
The dipping of metal components into thermoplastic powders or, Fluidised Bed dipping, as it is sometimes known, is the oldest form of plastic coating and goes back to 1952.
Thermoplastic coating material is ground into a fine powder and kept in a steel box (Fluid Bed) open at the top and with a fine gauze across the bottom, fine enough not to let the powder particles through. Air is then introduced up through the gauze which makes the powder particles rise and act like a box of fluid, hence ‘Fluidised Bed’.
Metal components are pretreated, heated up to between 250° and 400° C depending upon the coating required, then dipped into the fluid bed of plastic. The powder particles melt onto the metalwork forming a smooth continuous coating.
Coating materials we use include Low Density Polyethylene and the PPA ® range. The resultant appearance is a matte finish.
What are the advantages of using plastic coating instead of other coating treatments?
- Thicker coatings than powder coating
- Smooth continuous coating
- Very long service life
- Extreme corrosion resistance
- Excellent chemical resistance
- Excellent UV and weather resistance
- Non-toxic coatings
