ZINCALUME ®

Zincalume® coated steel has long-term corrosion resistance in moderate conditions. It offers a blend of versatility and durability. Zincalume® combines 55% aluminium alloy coated steel and 45% zinc, giving advantages of both metals. The resulting alloy coating enhances corrosion resistance, making it ideal for applications such as roofing and cladding.

 

 

Zincalume® has a finely spangled silvery matte finish. After exposure, the surface finishing darkens over time as the resin coating weathers away. This change is a natural one and visual only. The protective properties of the product are not affected.

Zincalume® is readily paintable using good quality primer and water-based acrylic topcoats. Paint manufacturers instructions should be followed. Dirt, grease and any loose material must be cleaned off the surface so the surface is clean and dry prior to the first coat being applies.

If your Zincalume® product becomes wet during storage, the product should be immediately separated, wiped clean with a cloth and placed in a position where it can completely dry.

The fasteners durability should equal (or exceed) that of the roofing or cladding product and should be suitable for the environment. Stainless steel fasteners and lead headed nails should not be used.

Flashings and ridge capping should be manufactured from the same coating system as used for the main roof area to ensure equal durability.

Your warranty is dependant on two things: having the right product for the right environment and ensuring it is maintained in line with the manufacturers maintenance recommendations.

Zincalume® product are recommended for use in moderate environments only. A moderate environment is characterised by:

  • Little or no salt deposits

  • The occasional smell of salt in the air

  • Typically starts 500m-1000m from breaking surf such as is found on exposed coasts, or in the immediate vicinity of clam salt water such as estuaries

Zincalume® coated steel performs well in most areas not regularly washed by rainwater. However, regular washing of areas not naturally rain washed is essential to the longevity of the product and not voiding the product warranty.

Maintenance recommendations for Zincalume® used as roofing and wall cladding as is follows:

In almost all applications, Zincalume® will out perform galvanised steel. There are, however, a small number of applicatipns for which galvanised steel is more suitabke.

 Zincalume® coated steel must not be used for:

  • Formwork in contact with wet concrete

  • Products to be embedded in concrete

  • Animal shelters where ammonia levels are constantly high

  • Fertilizer storage sheds and containers

  • Culverts, or where Zincalume® coated steel would be buried in the grund

  • Water tanks

  • Highly alkaline environments (e.g. cement manufacturing)

  • Coolroom products
