COLORBOND® coated steel should not be installed in contact with non-galvanised steel, copper, brass, lead, stainless or monel metal. Do not use lead flashing with COLORBOND® products.
If nestable profiles become wet while closely stacked, formation of wet storage stain or ‘white rust’ is possible. To minimise the possibility of inadvertent damage:
The substrate under the paint film is ZINCALUME® coated steel which complies with the Type AM, and AZ coatings requirements of AS1397:2011. The colour coat complies with AS2728.
COLORBOND® products are not suitable for use in the following situations:
COLORBOND® products cannot be soldered.
COLORBOND® products 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. Colour change during service will depend on the colour chosen, aspect, design of the structure and the environment.
Class 4 fasteners are recommended for outside conditions when using COLORBOND® coated materials.
To ensure appropriate quality products are used in construction, comprehensive specifications from Stramit's relevant Product Technical Manuals should be included in the design documentation, including reference to COLORBOND® material.
COLORBOND® material can be easily cut, where required, using a power saw with a steel cutting blade or a power nibbler and, for localised cutting, tin snips. Avoid the use of abrasive discs as these can cause burred edges and coating damage. Please dispose of any off-cuts carefully.
Please refer to the SA HB 39:2015 Installation code for metal roof and wall cladding for correct installation guidelines, particularly in regard to underlays/building papers, penetrations, flashings, fasteners and pitch.
Where sealed joints are required, use only neutral cure silicon rubber sealant together with mechanical fasteners such as aluminium rivets. Do not weld or solder.
The service life is extended by regular washing. A mechanical wash every six months is recommended, more often if contaminants build up. At these times inspect for damage and failing fasteners, and repair these.
