COLORSTEEL® CP-Antibacterial

CP-Antibacterial acts like an extra layer of protection against stock contamination, providing peace of mind to everyone from restaurants and commercial kitchens to manufacturers and exporters. 

Much of its effectiveness can be contributed to antibacterial technology that’s incorporated into its production.

CP-Antibacterial is available in Titania, an off-white colour, to help with ease of cleaning. 

Features

Features

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 system is applied.

The system is particularly suited for internal applications where its anti-bacterial properties will be most effective.

Appearance

COLORSTEEL®  CP-Antibacterial steel is only available in the colour Titania. Other colours are available in the COLORSTEEL® CP steel range.

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.

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.

Identification

COLORSTEEL® ENDURA® prepainted steel is identified by a brand applied to the reverse surface, indicating product type and date of manufacture.

Availability

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.

Durability

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.

Composition

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 AS1397:2011. 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.

Applicable Standards

All COLORSTEEL® products are supplied to conform to the appropriate NZ standards.

Dimensional Tolerances:

  • AS/NZS 1365

Organic Finishes:

  • AS/NZS 2728: Prepainted and organic film/metal laminate products – performance requirements for interior/exterior applications in buildings
  • AS/NZS 4020: Testing of products for use in contact with drinking water

Guidelines For Use

Guidelines

Handling and Forming

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.

Storage

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 colour change.

Design

Listed below are factors you should consider:

  • The lightweight nature of a composite panel coupled with a structural capability may make the need for an internal frame for smaller projects obsolete.
  • In a coolroom, moisture is ever present. It is paramount to the overall corrosion performance that water must be allowed to drain freely away from a composite panel. This is critical at the base of the panel where poor detailing can allow water to come in contact with the foam core. Once moisture is trapped in a panel, corrosion will be accelerated.
  • It is recommended that a dwarf masonry wall be incorporated in the coolroom design. This will allow water to drain away and also protect the base of the coolroom wall.
  • Bottom channels of the walling should be manufactured from compatible materials and be designed to allow water to drain freely.

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.

Good Practise

The following good practice is recommended:

  • The use of soft nylon bristle brooms coupled with water pressures of less than 400psi (2760kPa) is recommended.
  • Regular inspection of slip joints and the general detailing of the coolroom will highlight problems before they become major concerns.
  • Monitoring of sealant performance at the base of the panel is critical to prevent water ingress.
  • Once the moisture has entered the panel, it will expand when frozen, causing the panel to bulge. This causes the seals to be broken and moisture-laden air to enter the panel, causing the panel to bulge further, greatly diminishing the efficiency of the coolroom.
  • Bulging of panels could indicate that moisture has entered the panel through the following means:
    - A poorly sealed slip joint
    - A gap that has developed between the bottom channel and the panel
    - A panel has been punctured by, for example, forklift tines
  • Consideration should be given to means of preventing damage to coolroom walling incurred whilst handling stock stored within and around the coolroom.
