ColorCote ZinaCore (formerly known as ZR8)

ColorCote ZinaCore is pre-painted steel with hot-dipped aluminium and zinc alloy, designed for excellent durability, colour retention and formability.

It is the innate ability to be easily re-formed offers profile options to suit any overall design aesthetic, all at an affordable price.

Option of 70% PVDF top coat, for greater paint protection in industrial environments where corrosive chemicals are present.

Key Features
  • Baked on colour will give many years of vibrant life without any signs of fading, cracking or peeling, under normal conditions.
  • Can be pliably roll-formed to the profile of user's choice.
  • Only a fraction of the weight of concrete, meaning it is safer in the event of an earthquake, and also lowers labour, infrastructure and material costs of installation.
  • Provides excellent gloss and colour retention.
  • Option of 70% PVDF top coat, for when you need greater paint protection.
  • Available in over 40 colours.
Scope of Use

ZinaCore has very good colour and gloss retention and is suitable for roofing, cladding, and rainwater goods. It is ideal for interior uses and exterior environments where corrosion levels are moderate. It is also suitable for fencing applications. 

ColorCote ZinaCore X is ideal for industrial sites where there is a high risk of deterioration from corrosive elements in the environment. 

Limitations on Use

ColorCote ZinaCore and ZinaCore X are not suitable for use in the following situations:

  • Animal shelters where excessive ammonia fumes can accumulate due to inadequate venting, or where direct contact with animal effluent can occur.
  • Water tanks or areas where a constantly wet environment is maintained.
  • In direct contact with concrete or where lime deposits are evident.
  • In contact with soil (allow a 75mm run off below cladding sheets to ground level).
  • Roofs with pitches less than three degrees (eight degrees for standard corrugated profile).

ColorCote no longer warrant ZinaCore for rainwater goods and fascia, as MagnaFlow or AlumiGard products are more durable for these uses.

3° Minimum Roof Pitch Required
Statement of Building Code Compliance

ColorCote ZinaCore and ZinaCore X, under normal well washed conditions of exposure, can be expected to show no cracking (other than that which may occur during forming), flaking or peeling of the paint film for 15 years from the date of installation.
