<p>Features and Applications
A copper coated solid wire suitable for single pass or multipass welding of unalloyed and low-alloyed carbon-manganese steels.
The higher Si-Mn content increases the weld metal strength and leaves a good bead appearance.
Designed for semi-automatic and full-automatic GMAW applications.
Good mechanical properties at sub-zero temperatures down to -40ºC.
Vacuum-sealed aluminium foil packaging to prevent moisture absorption.
Precision layer wound for superior wire feeding characteristics.
Typically used on boilers, industrial machinery, bridges, shipbuilding, automotive, rail, structural and engineering fabrications etc.
Green wire is produced using virgin raw materials sourced from specialised steel mills, which ensures consistent reliability and quality.

<p>Features and Applications
Solid wire suitable for welding weather resistant structural steels like Corten and other high strength low-alloy steels.
Alloyed with copper and nickel which gives a high resistance against atmospheric corrosion.
This wire provides a unique aesthetic appeal and can be identified by its typically reddish rust or patina look for structural and artistic applications.
Precision layer wound for superior wire feeding characteristics.
Typically used on the construction of containers, tanks, bridges, building panels, chimneys, means of transport, offshore platforms etc.
Green wire is produced using virgin raw materials sourced from specialised steel mills, which ensures consistent reliability and quality.
