Metal Profiled / Standing-Seam Cladding
Technical product reference for steel and aluminium profiled facade cladding — Colorbond profiled sheet, mini-orb, and standing-seam metal cladding systems for NCC 2022 compliant facade remediation. Includes concealed-fix standing-seam aluminium, Colorbond corrugated/trimdeck for facades, and trapezoidal steel profiled cladding.
What is metal profiled and standing seam cladding?
Metal profiled and standing seam wall cladding systems use roll-formed or flat sheet metal panels fixed to a structural subframe to form the outer weather skin of a building. Steel (Colorbond), zinc, copper, and aluminium are all non-combustible metal options available for NCC 2022 compliant Class 2 building facades.

Colorbond Steel — Standing Seam Wall Cladding
Colorbond steel standing seam wall cladding — non-combustible — roll-formed
System Description
Colorbond pre-painted Zincalume steel standing seam wall cladding from BlueScope Steel is the benchmark metal profiled cladding system for Australian industrial, commercial, and Class 2 residential buildings. Roll-formed from Colorbond steel (Zincalume base with pre-painted PVDF or acrylic coating), it is non-combustible under NCC 2022 and available in a range of standard Colorbond colours. Standing seam profiles use a concealed clip system with no exposed fasteners on the weather face, creating a clean vertical or horizontal facade expression. Available in a range of standard profiles including 25/75/150/200 mm flat-seam and curved profiles through local rollformers. AS 1562.1 compliant design. Widely used for cladding replacement on Class 2 buildings in industrial precincts and contemporary residential towers.
Technical Properties
- Non-combustible steel substrate — NCC 2022 compliant for external walls of Class 2–9 buildings
- Colorbond pre-painted finish — PVDF or polyester coating — Colorbond standard colour range
- Standing seam concealed-clip fix — no exposed fasteners on facade weather face
Limitations
- Thermal expansion is significant — a 6 m Colorbond panel expands approximately 6 mm over 50°C temperature swing — must be accommodated in clip and joint design
- Metal facades transmit sound — rain noise on metal profiled cladding is a known amenity issue in occupied Class 2 buildings
- Colorbond colour range is fixed — custom colours not available; colour must be selected from standard Colorbond palette

Rheinzink Standing Seam — Zinc Wall Cladding
Zinc standing seam wall cladding — titanium zinc — pre-weathered finish — non-combustible
System Description
Zinc (titanium zinc) standing seam wall cladding is the premium architectural metal facade option, widely used in Europe and increasingly in Australian high-end residential, commercial, and Class 2 remediation projects. Rheinzink (Germany) is the leading titanium zinc facade product, available in pre-weathered blue-grey (prePATINA bluegrey) and graphite-grey finishes that replicate decades of natural zinc patina from day one. Non-combustible and NCC 2022 compliant. Service life of 80–100+ years in normal atmospheres. Zinc naturally re-seals minor scratches through the patination process. Suitable for coastal environments (confirmed with Rheinzink Australia for specific marine exposure categories). Standing seam concealed-clip fixing eliminates exposed fasteners. Zinc expands significantly — expansion provisions are more critical than steel and must be designed by the installer.
Technical Properties
- Titanium zinc alloy — non-combustible — NCC 2022 compliant for all Class and height combinations
- Pre-weathered finish available from day one — eliminates the 5–15 year natural weathering period
- Service life: 80–100+ years in normal atmosphere — 60+ years in coastal environments
Limitations
- High material cost — titanium zinc is significantly more expensive than Colorbond steel per m²
- Significant thermal expansion — zinc expands 2.2× more than steel per °C — expansion clips and joints must be carefully designed
- Specialist installers required — zinc standing seam is a trade skill not common to standard roofing/cladding contractors

Fielders KingFlor / Panelrib — Profiled Steel Wall Cladding
Profiled steel wall cladding — Fielders — face and concealed-fix — NCC 2022
System Description
Fielders Steel is one of Australia's leading profiled steel cladding manufacturers, offering a range of wall cladding profiles in Colorbond pre-painted steel including Panelrib (ribbed wall profile), Longline (flat-seam profiled panel), and concealed-fix profiles. All profiles are manufactured from BlueScope Colorbond steel and are non-combustible under NCC 2022. Fielders has a national rollformer network providing project-specific panel lengths and profiles cut to order. Face-fixed profiles use standard Colorbond screws; concealed-fix profiles use clip systems. The wider Fielders range also includes box-rib and corrugated profiles suited to industrial and contemporary residential facades. Popular for Class 2 building remediation where industrial aesthetic and rapid installation are preferred over premium architectural panels.
Technical Properties
- Non-combustible Colorbond steel — NCC 2022 compliant for external walls
- Range of profiles: Panelrib, Longline, concealed-fix — confirm profile availability with local Fielders rollformer
- Panel lengths: roll-formed to project-specific lengths — no joints in long runs
Limitations
- Industrial aesthetic — profiled steel facade appearance does not suit all Class 2 building design contexts
- Face-fixed profiles have exposed fasteners — specify concealed-fix profile where clean appearance is required
- Thermal expansion must be managed in screw-fix joints — over-tightening of screws causes pull-through on thermal cycling

KME Copper — Standing Seam Facade
Copper standing seam wall cladding — premium architectural — patinating finish
System Description
Copper standing seam wall cladding is the most distinctive and long-lasting metal facade option — a premium specification for landmark, heritage, or architecturally significant Class 2 buildings. Pure copper is fully non-combustible and NCC 2022 compliant. Over time, copper develops a natural green-blue patina (verdigris) that is stable and protective — the patina is often the desired design outcome. Pre-oxidised and pre-patinated copper is available from KME and Aurubis where immediate natural weathered appearance is required. Service life of 100+ years in most environments. Specialist copper-working contractors required — copper requires soldering, not welding, and different tools from steel. Copper run-off stains adjacent materials green — this is a critical design consideration for drainage routing.
Technical Properties
- Pure copper — fully non-combustible — NCC 2022 compliant for all Class and height combinations
- Service life: 100+ years — natural patina provides stable long-term corrosion protection
- Pre-oxidised and pre-patinated grades available — immediate natural weathered appearance from installation
Limitations
- Extremely high material cost — copper is one of the most expensive facade metals per m²
- Copper run-off creates green staining on adjacent materials (concrete, render, glass) — drainage routing critical
- Specialist copper-working contractors required — not interchangeable with standard metal cladding contractors

Do not confuse metal profiled / standing-seam facade cladding with:
- Profiled steel roofing sheet — roof-grade corrugated or trimdeck sheet designed for horizontal fall and roof loads; different structural design, spanning capacity, and weather-sealing details from facade-rated profiled cladding
- Insulated metal sandwich panels — composite panels with metal faces and foam insulation core; different product category with different fire performance, spanning, and fixing system — listed separately from profiled sheet cladding
- Metal cladding on exposed timber framing — timber subframe is combustible and not suitable for Type A or Type B NCC 2022 buildings; metal profiled facade cladding must be fixed to a non-combustible or engineered subframe system
- PVDF-coated flat sheet — flat aluminium or steel sheet for custom-fabricated cassette cladding; different product form from profiled standing-seam — different structural behaviour and fixing method
Disclaimer
Information is general only. Metal profiled and standing-seam cladding must be confirmed against NCC 2022 and AS 1562 for facade application. Thermal movement provision and concealed-fix system design require facade engineering review. Engage a facade engineer before specification.
