Applications of Aluzinc & Prepainted Aluzinc coils

 

AluzincZincalume and Galvalume are different trade names of one product. Aluzinc is cold rolled galvanized steel with metal coating composed of Aluminium (55%), Zinc (43.4%) and Silicon (1.6%). It is formable, weldable and readily accepts paint finishes . DANA STEEL has a state of the art Galvanizing with DUAL POT system at it’s Continous Galvanizing Line  facility in Dubai UAE. Herein Aluzinc Coils are manufactured in it’s Manufacturing Facility .

 

Aluzinc is used in applications where long life is an essential requirement. Aluzinc coated steel has superior long term corrosion resistance in most atmospheric conditions. This is achieved through the combination of the sacrificial protection of the zinc and the barrier protection of the aluminum. Corrosion rates vary according to the severity of atmospheric conditions. Aluzinc steel coatings out-perform galvanized coatings from 2 – 6 times. The protective mechanism for Alu-zinc and hot-dip-galvanized steel are such that the hot-dip-galvanized coating initially protects better but the zinc coat will gradually corrode away more and more in the vicinity of the edge and the protective effect will be lost. Then the aluminum part of the Aluzinc coating will persist for a longer period of time, and the protection will thereby remain

 

 

The main properties of Alu-zinc are:

  • Excellent resistance to corrosion and perforation
  • Aesthetic appearance -silvery metallic spangle
  • Good abrasion resistance due to its surface hardness
  • Excellent thermal and light reflectivity
  • Excellent resistance to high temperatures (up to 315°C)
  • Ease of working: profiling, deep drawing, bending etc
  • Environment-friendly product – 100% chromium free passivation
  • Product recommended for food storage

 

 

APPLICATIONS

Nowadays Alu-zinc is commonly used for construction projects

  • Roofing and flashings
  • Façades – traditional, architectural and industrial
  • Wall claddings
  • Gutters and downpipes
  • Fences
  • Steel house frames
  • Garage doors
  • Garden sheds
  • Vehicle exhaust components
  • Flues
  • Interior cladding,
  • Solar shading
  • Water drainage systems (gutters, drainpipes etc), as well as for many
  • Indoor applications -ceilings, partitions etc.
