Galvanized Wire is made to ASTM B498; ASTM A 475; BS 183 etc. The metallic zinc coatings applied by the galvanizing process are an effective way of combating corrosion in steel. Galvanized wire for cable application is available in a Class A coating; Class B coating and Class C coating.
Product Description
Guy Wire ASTM A 475
Galvanized Wire is made to ASTM B498; ASTM A 475; BS 183 etc. The metallic zinc coatings applied by the galvanizing process are an effective way of combating corrosion in steel. Galvanized wire for cable application is available in a Class A coating; Class B coating and Class C coating.
Class A coatings are smoother, however less corrosion resistant than heavy galvanized coatings and are often used in normal wire working applications. Some typical end users include cages, bucket handles, coat hangers and baskets.
Class B and Class C coatings are used in conditions where atmospheric corrosion is severe. End users include crop support wires where chemicals are used, pool fencing or chain mesh in coastal areas.

Diameter Range: 1.57 -4.00 mm
Galvanised Wire Working Specifications
Given that galvanized wire is classified according to the amount of zinc coating, the following table outlines the difference between standard, heavy galvanized and extra-high galvanized wire.
| Nominal Diameter | Minimum Coating Mass (g/m2) | ||
| Standard Galv. | Heavy Galv. | Extra-highGalv. | |
| over 1.6 mm up to and incl. 1.90mm | 210 | 420 | 630 |
| over 1.90mm up to and incl. 2.30mm | 220 | 440 | 660 |
| over 2.30mm up to and incl. 2.70mm | 230 | 460 | 690 |
| over 2.70mm up to and incl. 3.10mm | 240 | 480 | 720 |
| over 3.10mm up to and incl. 3.50mm | 260 | 520 | 780 |
| over 3.50mm up to and incl. 3.90mm | 270 | 540 | 810 |
Tensile Strength (Mpa)
The tensile strength is defined as the maximum load achieved in the tensile test, divided by the cross-sectional area of the wire test piece. Galvanized Wire is produced using soft, medium and hard grade wires. The following table specifies the tensile range according to the grade:
| Nominal Wire Diameter | Stress at 1% Elongation (Mpa) | ||
| Class A | Class B | Class C | |
| over 1.6 mm up to and incl. 2.30mm | 1310 | 1240 | 1170 |
| over 2.30mm up to and incl. 3.05mm | 1280 | 1210 | 1140 |
| over 3.05mm up to and incl. 3.60mm | 1240 | 1170 | 1100 |
| over 3.60mm up to and incl. 4.80mm | 1170 | 1100 | 1070 |
| Nominal Wire Diameter | Tensile Strength (Mpa) | ||
| Class A | Class B | Class C | |
| over 1.6 mm up to and incl. 2.30mm | 1450 | 1380 | 1310 |
| over 2.30mm up to and incl. 3.05mm | 1410 | 1340 | 1280 |
| over 3.05mm up to and incl. 3.60mm | 1410 | 1340 | 1280 |
| over 3.60mm up to and incl. 4.80mm | 1380 | 1280 | 1240 |
Please note that the sizes mentioned above are indicative only and do not specify the size range available from my products range.
| Nominal Wire Diameter | 10in Elongation (%) | ||
| Class A | Class B | Class C | |
| over 1.6 mm up to and incl. 2.30mm | 3 | 3 | 3 |
| over 2.30mm up to and incl. 3.05mm | 3.5 | 3 | 3 |
| over 3.05mm up to and incl. 3.60mm | 4 | 3 | 3 |
| over 3.60mm up to and incl. 4.80mm | 4 | 4 | 4 |
Steel Chemistry
A combination of steel grades is used and heat treatment processes to manufacture soft, medium and hard tensile grades. The table below is indicative only of steel chemistries used.
| Tensile Grade | % Carbon | % Phosphorus | % Manganese | % Silicon | % Sulphur |
| Normal | 0.5~0.85 | 0.035 | 0.5 ~1.10 | 0.10~0.35 | 0.045 |
