WHAT IS INNOGAL™?
  • INNO vative GAL vanizing - wide range of value added wire by products
  • Alloy of Zinc-Aluminum at 95% Zn and 5% AI
  • Presence of aluminum in the INNOGAL™ coating leads to an adherent aluminum oxide layer formed on the surface
  • This protective aluminum oxide layer slow down the active reaction of the zinc in the alloy and increases the life of INNOGAL™ considerably
  • Additional corrosion protection by the Fe/Zn/Al layer (formed on the steel when aluminum diffuses into steel) after Zn/Al is fully corroded
INNOGAL1
DOUBLE DIPPING PROCESS
  • Properly annealed, cleaned and fluxed steel acquires a galvanized coating in the first bath
  • Transforms into aluminum-iron-zinc in second molten INNOGAL ™ bath to achieve coating composed of 95% zinc and 5% aluminum eutectic alloy
THE SPECIFICATIONS

BS EN 10244 - 2 : 2009

Steel wire and wire products

Non-ferrous metallic coatings on steel wire

ADVANTAGES OF THE PROCESS
  • Corrosion resistance up to FOUR times that of galvanized wire
  • Can be extensively redrawn and subjected to severe wire forming operations (Superior ductility)
  • A cost effective alternative to higher prices anti-corrosion materials and coating
  • Environmental friendly
  • 14 dedicated INNOGAL ™ lines to meet volume demands and fluctuating requirements
ILLUSTRATION OF ZINC GALVANIZED AND INNOGAL™ WIRE COATING
INNOGAL2
  • Zinc galvanized wire is formed by Fe + Zn layer and an outer layer of pure Zinc.
Picture1
  • INNOGAL ™ is formed by a layer of Fe+Al+Zn acting as sacrificial coating.
  • Outer layer composed of fine, alternating layers consist of Zn and Al in the form of lamellae.
CORROSION OF WELDING POINTS
INNOGAL7
Zinc Galvanized Steel Wire
  • Welding points are exposed to the air as the coating is melted during the welding process
  • As a result red rust appear
    • innogal-u69349-fr
    iinogal
  • With the layer of sacrificial protection or cathodic protection (FeAl3 ), welding points are protected from rusting.
