Put an extra layer of protection around stock in coolrooms and food preparation areas.
COLORSTEEL® CP ANTIBACTERIAL steel is a prepainted, galvanised New Zealand Steel product used to make insulated panels for coolrooms and other hygiene sensitive environments.
COLORSTEEL® CP Antibacterial incorporates Microban® to put an extra layer of protection around stock in coolrooms and food preparation areas. The world’s leading anitbacterial technology, Microban® complies with food contact regulations in Australia and New Zealand, and is approved by the U.S FDA and the European Union Scientific Commmittee For Food.
Microban® is an imbedded ingredient in the paint system used on COLORSTEEL® CP ANTIBACTERIAL. This means it won’t wash or wear off, and will last for the whole life of the coating.
COLORSTEEL® CP ANTIBACTERIAL is available in Titania, an off-white colour for easy cleaning.
COLORSTEEL® CP Antibacterial coated steel has been specifically developed for the food and related industries. The paint system consists of a ZINCALUME® steel substrate to which a customised, prepainted finish system containing Microban® is applied.
The system is particularly suited for internal applications where its anti-bacterial properties will be most effective.
COLORSTEEL® CP Antibacterial steel is only available in the colour Titania.
Other colours are available in the COLORSTEEL® CP steel range, however only the Titania paint system contains the Microban® anti-bacterial additive.
Microban® is the world’s leading anti-bacterial technology. Incorporated into the paint system, it inhibits the growth of bacteria that come in contact with COLORSTEEL® CP Antibacterial, including organisms that can cause odours, stains, contamination, food poisoning and allergies.
The specially formulated backer coat has been developed to combine with readily available adhesives to form a strong bond with the panel core.
For sandwich panel applications requiring colours other than Titania, the product should be ordered as COLORSTEEL® CP steel, which does not contain the Microban® anti-bacterial additive.
It is generally recommended that lighter colours be utilised for insulated panel applications. This is because the higher surface temperatures achieved on dark coloured panels, which are externally exposed in service, can cause degradation of the insulation core material, and ultimately result in delamination of the steel skin from the core. However, given that the maximum temperature of different colours can vary according to climate, and that the maximum service temperature of the core will depend upon its composition, it may still be possible to develop a suitable sandwich panel system utilising dark coloured skins. It is therefore recommended that you contact your nearest New Zealand Steel insulated panel supplier, for assistance in determining the suitability of other colours for your proposed application.
COLORSTEEL® Endura™ prepainted steel is identified by a brand applied to the reverse surface, indicating product type and date of manufacture.
COLORSTEEL® Endura™ prepainted steel is available ex stock from most roofing distributors in a range of COLORSTEEL® Endura™ colours. Where a colour is not available, delivery is normally within two to four weeks, depending on the location of the distributor.
When rollformed, installed and maintained in accordance with New Zealand Steel’s recommendations, COLORSTEEL® Endura™ prepainted steel is warranted by New Zealand Steel to meet the performance requirements of NZBC B2.3(c) for a 15 year durability when used for the manufacture of roof and wall claddings. COLORSTEEL® Endura™ products are expected to fade uniformly over the surface, the extent being no more than 8 Hunterlab units on the Delta E scale, and have a chalk rating of 4 (AS 1580 481.1.11, 1998) after 10 years exposure.
The COLORSTEEL® CP Antibacterial prepainted steel substrate is steel strip, commonly 0.40 mm or 0.55 mm thick and coated with a 45% zinc, 55% aluminium alloy to a nominal coating mass of 150g/m2 manufactured in accordance to AS1397:2001. A range of thicknesses, widths and strengths are available. Following pretreatment, a corrosion inhibitive primer and top coat are applied to the outer surface and a corrosion inhibitive primer and a backer to the reverse side. These coatings are oven cured to provide colour and corrosion performance.
All COLORSTEEL® products are supplied to conform to the appropriate NZ standards.

COLORSTEEL® CP Antibacterial, CP and CPz prepainted steel must be carefully handled during transport and fabrication to avoid damaging the high quality surface finish. Examine the material carefully when it is delivered. Any faults in the product should be reported immediately and shall be made good by the supplier. Experience has shown that roll-forming lubricants have an adverse effect on the decorative and physical properties of prepainted steel. New Zealand Steel does not recommend the use of roll-forming lubricants on COLORSTEEL® prepainted steel products.
If COLORSTEEL® CP Antibacterial, CP and CPz prepainted steel is to be stored for any time prior to manufacture or placement, it must be stored in dry, well-ventilated conditions. Incorrect storage promoting water entrapment between panels (including condensation) may irreparably damage the coating system or promote color change.
Listed below are factors you should consider:
The runoff from condensers should not be allowed to discharge via copper pipes over COLORSTEEL® prepainted steel products. All run off should be diverted away from the COLORSTEEL® prepainted steel surface.
Note: It is a condition of the New Zealand Steel warranty that your design, construction, installation and ongoing maintenance prevent moisture ingress into panel cores and joins throughout the life of the product.
Various panel manufacturers have different methods of joining panels. Most employ a variation of a male/female slip joint. Both corrosion performance and the efficiency of the coolroom will be affected if particular attention is not paid to these joints, which must fit snugly together to stop the ingress of moisture. Most panel manufacturers stipulate that sealants be incorporated into all slip-joints. This is especially important if the panels are to be washed down regularly. Mastic type vapour barriers are also recommended for some installations.
The following good practice is recommended:
