Summary of Guidelines for using COLORBOND® steel

This page contains some basic recommendations for the use of COLORBOND® steel products. BlueScope Steel recommend that you:-

Always use the recommended steel grade to suit your environment and any special corrosive influences,
Store material clear of the ground and protect from rain and moisture prior to installation,
Always use fasteners with durability equal to the material being used and which have carbon-black-free washers,
Avoid materials and liquids which can cause corrosion, such as lead and copper, green or CCA (Copper-Chrome-Arsenic) treated timber, uncoated steel supports, fertilisers, pesticides and abrasive cleaners,
Avoid using galvanised gutters with roofing made from COLORBOND® steel,
Follow manufacturers recommendations for roof pitch, fastener spacings and type, support spacings and other laying procedures when installing products,
Avoid the use of black carbon ('lead') pencils for marking sheets,
Use a metal cutting saw or blade, or shears to cut sheets rather than angle grinder discs.
Use only neutral cure silicone rubber sealants,
Debris from cutting, piercing & screwing should be removed at the end of each day, and not left on the roof or in the gutters,
Avoid immersion in concrete, soil or water, or build up of debris against the product,
Avoid contact with brick cleaning acid,
Avoid using touch up paint,
Areas not washed by rainwater should be hosed down at least every six months (more frequently in areas with industrial fallout or high salt concentrations).
