Showing results 1-12 of 15
Profiled steel cladding – dust, dirt, air-borne salt
-
Lack of rain washing, or soffit prevents rain washing at top of walls
Profiled steel cladding – scratching
-
Trees or shrubs brushing against cladding
-
Sheets dragged rough surface during installation
-
Careless stacking before installation
Profiled steel cladding – dents/impact damage
-
Stones, balls, vehicles
-
Sheets damaged during installation
Profiled steel cladding – corrosion: white rust
-
Corrosion of the zinc when water is trapped between sheets at laps and joints, or during storage prior to installation
-
Insufficient rain washing
Corrosion: red rust on galvanised mild steel cladding
-
Galvanised coating has eroded to expose bare metal
-
Profiled metal cladding is in contact with or has run-off from cedar or redwood, or timber treated with copper-based preservative treatment
-
Galvanised mild steel cladding has run-off from translucent sheeting (PVC), glass, pre-painted roofing, glazed tiles, unpainted zinc/aluminium alloy-coated mild steel or aluminium
-
Damage to the galvanised coating during fixing exposing steel
-
Exposure to a corrosive environment such as a swimming pool, or in coastal, industrial or geothermal areas
-
Inadequately primed end and/or side laps
-
Cladding in ground contact
-
Insufficient rain washing
Red rust on zinc/aluminium or aluminium/zinc alloy-coated steel
-
Corrosion of the steel when zinc/aluminium alloy coating has eroded to expose the steel
-
Cladding material in contact with or has run-off from cedar or redwood, or timber treated with a copper-based preservative treatment
-
Cladding has run-off from translucent (PVC) sheeting
-
Corrosion of the steel in a highly corrosive environment such as a swimming pool, or in coastal, industrial or geothermal regions
-
For factory coated material, wrong coating specification for the in-use conditions
-
Inadequately primed end and/or side laps
-
Cladding in ground contact
-
Insufficient rain washing
Profiled steel – localised corrosion at the base of walls
-
Cladding covered by soil/foliage
-
The back surface of the cladding is too close to the ground/touching the ground and not drying properly
-
Concrete has been placed up to and against cladding
-
High sub-floor moisture levels behind the cladding
-
Bottom of cladding is too close to a waterproof deck surface, apron flashing and not drying properly
Profiled steel cladding – peeling, flaking or cracking paint
-
Weathering, UV light exposure
-
For factory coated material, wrong coating specification for the in-use conditions
-
Coating at the end of its serviceable life
Profiled steel cladding – chalking
-
Effect of weathering – chalking will be more visible with darker colours
Profiled steel cladding – fading
-
Effect of weathering – darker colours are more prone to fading
Profiled steel cladding – micro-cracking at bends
-
Effect of aging or exposure to weather
Profiled steel cladding – buckling
-
Inadequate allowance for thermal movement at fixings – this occurs more commonly with dark coloured claddings
