TSN Wires : The Best of technology

TSN Wires employs state-of-the-art technology from New Zealand which is designed to among the highest level of environmental sustainability and lowest carbon emission process in the world in the areas of:

-Stress Relieve Annealing Process : The electric furnace is designed with a closed Chamber and uses hydrogen to prevent oxidation of the wire surface.

-Pickling Process : TSN uses non-acid in the pickling process, which does not generate acidic waste and is very environmental friendly.

-Pre Coating Process: The machine transfers wire without flux chemical and is designed to use input hydrogen to prevent oxidation reaction on the wire surface.

-Galvanizing Process: The process uses the heat remaining in the wire during the annealing process to help melting zinc.This will reduce energy usage significantly.

-Zinc Coating Mass Control Process:The electromagnetic wiping(EMW) technology employed has the ability the control thickness of zinc coating with small tolerance to produce the highest quality coating and minimize material wastage.


We are confident that our products.

  • Have excellent corrosion resistant properties.
  • Are uniformly galvaized with smooth wire surface
  • Provide premium quality coated wire quality with sacrificial anti-corrosion effect and remarkable adhesion.
  • Are designed and developed for high workability
