COLORSTEEL® Bounce®

Using a unique primer and a highly advanced top coat system COLORSTEEL® BOUNCE® delivers optimised solar reflectance of 77%! That’s great for the environment and can lead to significant savings on your power bill.

In summer, COLORSTEEL® BOUNCE® increases the amount of solar heat that is reflected, making a building’s roof, and the environment inside, much cooler. In essence it acts like an extra layer of insulation, meaning air conditioning doesn’t have to work as hard to keep inhabitants comfortable.

Lower thermal stresses also add to the long lifespan one can expect from COLORSTEEL® BOUNCE®.

Features

Features

The COLORSTEEL® BOUNCE® paint system consists of a ZINCALUME® steel substrate to which a prepainted finish system is applied. The system is designed to provide protection against corrosion in areas where moderate to severe environmental conditions are experienced. COLORSTEEL® BOUNCE® product is suitable for rollformed roofing applications. The COLORSTEEL® BOUNCE® paint system will exceed the service life of most traditional post painted systems.

Durability

When rollformed, installed and maintained in accordance with New Zealand Steel's recommendations, COLORSTEEL® BOUNCE® 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 roofs. COLORSTEEL® BOUNCE® 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® BOUNCE® 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 minimum 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.

Appearance

COLORSTEEL® BOUNCE® is a product optimised for solar reflectance and is available in one colour only. The backer coat is Perpetual Grey™.

Identification

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

Availability

COLORSTEEL® BOUNCE® prepainted steel is available from roofing distributors throughout New Zealand. Delivery is normally within two to four weeks, depending on the location of the distributor.

Drinking Water

Rainwater collected from roofs clad with products made from ZINCALUME® steel and COLORSTEEL® prepainted steel, will comply with the provisions of NZBC G12.3.1, provided the water is not contaminated from other sources.

The first 25 mm of rainfall from a newly installed roof must be discarded before drinking water collection starts. Where a paint or paint system is applied to the roof, its suitability for the collection of drinking water must be established.

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

Limitations Of Use

COLORSTEEL® BOUNCE® prepainted steel products are designed for use in moderate or severe environments, see the Environmental Categories, Warranty & Product Maintenance Brochure for more information. Before using COLORSTEEL® BOUNCE® prepainted steel products near sources of industrial pollution or in geothermal areas, consult New Zealand Steel's Technical Market Manager.

COLORSTEEL® BOUNCE® prepainted steel products should not be used in the following applications:

  • As a building cladding
  • As rainwater goods
  • As a roofing fascia
  • Embedded in concrete
  • In contact with permanently wet materials
  • Water tanks
  • In contact with soil, bark or similar
  • As concrete formwork
  • In intensive animal shelters

Copper or brass pipes must not be allowed to discharge onto COLORSTEEL® prepainted steel products or be allowed to come into contact with them.

The use of other materials in proximity to COLORSTEEL® BOUNCE® prepainted steel products must be in accordance with the New Zealand Steel Specifiers and Builders Guide.

Mixing of brands of prepainted material on the same building is not recommended by New Zealand Steel Limited.

Marking with lead pencils is not advised, and sealing washers should be low carbon non-conducting. 

Maintenance

Areas of COLORSTEEL® BOUNCE® prepainted steel not regularly washed with rain water, such as around solar voltaic panels, aerials or under trees, must be routinely washed to remove surface deposits to ensure satisfactory life is obtained from the product. Specific maintenance recommendations are given in the table below. Always wear soft soled shoes when walking on COLORSTEEL® BOUNCE® prepainted steel surfaces to avoid causing damage.

Maintenance Recommendations for COLORSTEEL® Bounce® Products Used For Roofing

 Environment
Moderate ISO Category 3Severe ISO Category 4Very Severe ISO Category 5
Roof Rain washing Rain washing Not Recommended
Unwashed and High Risk Areas Manual washing every 6 months Manual washing every 3 months Not Recommended

Fixings

  • Aluminium and factory painted fixings are acceptable
  • Stainless steel, Monel or other copper alloy fixings must not be used
  • Lead-head nails must not be used
  • Fixings that meet AS3566 class 3 and 4 are acceptable

Sealing & Joining

  • Use only neutral-cure silicone rubber sealants
  • Do not use abrasive cutting wheels
  • Do not weld, braze or solder

Touch-up Paints

These paints should not be used, as air drying paints have different weathering characteristics to the COLORSTEEL® prepainted steel coating. For more information, see Installation: Touch-up Paints.

Clean-up

All debris (particularly from roofing installation) must be removed from COLORSTEEL® BOUNCE® prepainted steel product surfaces at the end of each day's work. Take care not to damage the coating when removing sharp fixing debris. For more information, see Installation: Swarf Staining.

External Moisture

COLORSTEEL® BOUNCE® prepainted steel roof cladding must be installed at a minimum of 3° or over the minimum pitch given for the profile by the profile manufacturer, whichever is greater. Factors likely to affect the resistance of COLORSTEEL® BOUNCE® prepainted steel to external moisture include the quality of the installation, severity of the climate, roof configuration, material profile and design and execution of junctions between similar materials and other elements.

Hazardous Building Materials

The use of roofing manufactured from COLORSTEEL® BOUNCE® prepainted steel in accordance with New Zealand Steel's instructions will meet the nonhazardous performance requirements of NZBC F2.3.1.

Handling & Storage

If COLORSTEEL® prepainted steel products are to be stored for any time prior to forming or installation, they must be stored in dry, well ventilated conditions. Storage which allows water (including condensation) to be trapped between the sheets may damage the coating beyond repair. COLORSTEEL® BOUNCE® prepainted steel products must be handled carefully during transport, fabrication and fixing to avoid damaging the surface.
