Longlife technology




The wire lifespan is determined by the lifetime of the coating layer that protects the wire.



  • The coating is subject to damages depending on the corrosive potential of the air and on the aggressiveness of the chemicals used for treatments.
  • Pioneer in the heavily galvanized wires manufacturing, WireSolutions has invested steadily in the research of new coatings. Today, WireSolutions is well-known worldwide for the quality of its Crapal® coated wires.



  • Alloy of zinc, aluminium and magnesium.
  • Zinc gives an active and sacrificial protection while aluminium provides passive protection in covering zinc and significantly slowing down its sacrificial reaction.
  • Magnesium gives to the CrapalOptimum® coating an even higher resistance to corrosion.



  • Durable smooth surface
  • Increased lifespan
  • Concentricity: the required protection is only guaranteed if the protective layer is constant all around the wire.
  • Less zinc oxides in the soil.
  • CO2 footprint over time.
