Frequently Asked Questions

1. Which Gauge Standard does Concept Wire Industries Use?

We only sell and use wires quoted in millimetres. Customers are welcome to use our Wire Gauge Reference converter that will convert their wire gauge into millimetres. As there are different gauges used around the world, it is difficult to ensure that both customer and supplier are using the same gauge standard. Millimetres on the other hand is a standard size used world wide.

2. Millimetres or Inches?

All lengths of wire will be measured, cut and invoiced in millimetres or metres. Customers may quote in inches or feet, but keep in mind these measurements may be rounded up or down to meet the metric equivalent. To ensure exact dimensions of ±0.5mm it is best to quote length requirements in millimetres/metres.

3. What tolerances can I expect?

All straight and cut measurements are accurate to ±0.5mm millimetres. Customers can request a maximum or minimum limit.

4. What are the thinnest and thickest wire diameters I can order?

The thinnest wire we currently stock is 0.46mm. The thickest wire we stock is 12.7mm. Not all wires types are available in certain diameters. Please check with the office prior to placing your order.

5. What are the longest and shortest wires I can order?

The longest straight and cut measurement is 6 metres. The shortest straight and cut measurement is 50mm. These measurements do vary depending on the wire diameter, so please check with the office prior to placing your order.

6. What are Concept Wire Industries operating hours?

Our dispatch and inwards goods are open from 6.00am and close at 4.00pm Monday to Thursday, and 6.00am to 3.00pm on Fridays. Pick-ups and deliveries outside of these hours can be arranged by contacting the office.

7. What are the lead times for customised products?

Generally we try and offer a 3 day turnaround from placement of your order. This can vary depending on prior orders and wire diameters. To ensure lead times are kept to a minimum, Concept Wire Industries have 10 straight and cut wire machines with the capability of straightening wire from 1.0mm up to 15mm.

8. What is the difference between HDLC, annealed, spring and galvanised wire?

HDLC (Hard drawn low carbon) Wire has been cold drawn to the required diameter and not subjected to any subsequent treatment process. It will take moderate bending or flattening, machineability is fair and the wire can be roll threaded.

This is a general purpose manufacturing wire suitable for a large range of applications. Various applications include supermarket trolleys, shelving, baskets, racks, hooks and general automotive parts. HDLC can be plated and plastic coated. Tensile strength and chemical properties can be obtained from the Onesteel® website www.onesteel.com.

Annealed wire is similar to HDLC with the exception that it is heated to extremely high temperatures for around 8 hours in an annealing furnace. This process results in an extremely soft and ductile wire which is suitable for manual tying purposes in the building and manufacturing industries.

Mechanical Spring Wire is manufactured as either bright (hard drawn) or drawn galvanised wire. Careful selection of steel feed grades, correct heat treatment of the feed, and subsequent cold
drawing to finished size under controlled conditions combine to produce wire capable of withstanding the deformation and operational stresses inherent in spring manufacture and use. Spring wire differs from HDLC mainly due to an increase in the carbon content which results in significantly higher tensile strengths.

Galvanised Wire is made using a base HDLC wire and then coating the wire with molten zinc. This method is known as hot dip galvanising. The metallic zinc coatings applied by the galvanising process are an effective way of combating corrosion in steel. Galvanised wire for general manufacturing purposes is available in a standard galvanised coating (Class W02) or a heavy galvanised coating (Class W10). Ultra Heavy Galvanised (Class W25) is also available on request.

Standard galvanised coatings are smoother, however less corrosion resistant than heavy galvanised coatings and are often used in normal wire working applications. Some typical end uses include
cages, bucket handles, coat hangers and baskets.

Galvanised wires are also available in a range of different tensile strengths including soft, medium and hard. Specialised tensile strengths are also available for specific products including curtain
hooks, bucket handles and staples.
