Zinc and zinc alloy wire

Wire for metalization


Zinc wire and zinc alloy wire is used to apply zinc coatings by metal spraying process on steel products in order to protect them against corrosion. The wire also finds its application in the electronics industry. SHG zinc of the highest purity (99,995%) is used in the production process.

The application of zinc coatings by spraying is a method of anticorrosive protection. It has the following advantages over hot dip galvanizing or electroplating:

  • possibility to metalize structures at the construction area,
  • no dimension limitations as regards the dimension of coated elements,
  • possibility to mend the coating on construction site (welding areas, mechanical damages, etc.),
  • high resistance against mechanical defects,
  • sprayed zinc coating has higher durability and its thickness can be easily adjusted to suit the operational requirements,
  • zinc spraying eliminates the risk of thermal deformations of protected elements

Zinc spray is applied by use of electric arch or combustion guns. Depending on the type of the guns it is recommended to use zinc wire or zinc-aluminium wire with appropriate physical parameters.

Endless:
Cardboard barrels with a weight of 100, 150, 200, 250 kg .The wire is placed in a film bag and the barrels are capped.  The barrels are packed in pairs or as a group of four on a wooden pallet and protected with polyethylene bands. In case of regular customers, barrels can be reused at the customer’s consent. On request steel barrels also available.

Coils:

  • Coils, 20 or 25 kg, protected against uncoiling with polyethylene bands and put into cardboard boxes. The boxes are stacked on a wooden pallet, protected with polyethylene bands and wrapped with stretch foil.
  • Coils, 20 or 25 kg, protected against uncoiling with polyethylene bands and put into cardboard barrels. Barrels with a weight of 200 or 250 kg are packed in pairs on the pallet and protected with polyethylene bands.
  • Coils, 20 or 25 kg, protected against uncoiling with polyethylene bands, wrapped with heat-shrink foil, stacked on a wooden pallet, protected with polyethylene band and wrapped with stretch foil.

Spools:
Wire coiled on plastic or metal spools weighting 15 or 20 kg each and put into cardboard boxes. The boxes are stacked on a wooden pallet and protected with a polyethylene band.
