Who this guide is for
- Homeowners drawn to a modern metal-clad look
- People building or re-cladding contemporary designs
- Renovators comparing metal against other cladding families
- Anyone coordinating metal cladding with flashing and trim
Why choose metal cladding
Metal cladding offers durability, clean lines and a wide range of finishes. It can form flat panels, profiled sheets or standing-seam looks, suiting both whole facades and accent areas.
Its appeal is as much about appearance and longevity as performance. The metal and coating together determine how that look holds up over time.
- Durable with a crisp, modern appearance
- Available as panels, profiled sheets or standing seam
- Suits whole facades or accent areas
- Finish and metal together drive longevity
Aluminium and steel
Aluminium is light, corrosion-resistant in many environments and available in many coated finishes. Steel cladding is strong and common, with coatings such as protective paint systems that govern its corrosion resistance and color.
Both rely on their coatings for color and protection, so coating quality is central. Damage to the coating can expose the metal, which matters in harsh exposures.
- Aluminium is light and corrosion-resistant
- Steel is strong, with coatings driving protection
- Coating quality governs color and durability
- Coating damage matters in harsh exposures
Zinc and copper
Zinc and copper are architectural metals that develop a natural patina over time, giving an evolving, premium appearance. They are durable and often chosen for design-led or heritage projects.
They are specialist materials with their own detailing and compatibility needs, which is another reason to involve experienced professionals.
- Zinc and copper develop a natural patina
- Both are durable, premium architectural metals
- Often chosen for design-led projects
- Specialist detailing and compatibility apply
Coatings, color and weathering
Coatings determine the color, finish sheen and much of the corrosion protection on coated metals. Different coating systems offer different fade and durability characteristics, and the choice affects long-term appearance.
Understanding the coating route helps set realistic expectations for color longevity and upkeep, especially in sunny or coastal locations.
Compatibility, drainage and detailing
Metal cladding must be detailed so water drains correctly behind it, and metals in contact must be compatible to avoid galvanic corrosion. Fixings, flashing and the drainage gap all have to suit the system.
These are detailing questions that depend on the specific products. A professional should confirm compatibility and the full assembly.
Metal cladding planning checklist
- 1Decide on the look: panel, profiled sheet or standing seam
- 2Match the metal and coating to your exposure
- 3Consider coastal or harsh environments for corrosion
- 4Check compatibility between metals and fixings
- 5Coordinate cladding with the drainage gap and barrier
- 6Plan flashing and trim integration
- 7Set realistic expectations for patina or fade
- 8Keep manufacturer guidance for coatings and warranties
- 9Consider accent versus whole-facade use
- 10Have the full assembly confirmed by a professional
Common mistakes to avoid
- Ignoring galvanic compatibility between metals and fixings
- Underestimating coastal corrosion exposure
- Treating cladding as the sole water barrier
- Overlooking the drainage gap behind the panels
- Assuming coatings never fade or need attention
- Choosing a profile without checking detailing
When to involve a professional
- A cladding or building professional should confirm the metal, coating and assembly
- Metal compatibility and drainage detailing should be reviewed by a professional
- Coastal and harsh exposures benefit from specialist advice
- Requirements vary by location and project, so verify the assembly before work begins
Frequently asked questions
Questions readers ask about this topic
Does metal cladding rust?
It depends on the metal and coating. Aluminium, zinc and copper resist corrosion in many settings, while coated steel relies on its coating for protection. Coating damage and harsh exposures raise the risk, so a professional should match the system to your location.
What is a patina on zinc or copper?
It is the natural surface layer these metals develop as they weather, changing their color over time. Many people choose them precisely for this evolving appearance rather than seeing it as damage.
Can I mix metal cladding with other materials?
Yes, metal is often used as an accent alongside other cladding. The key is detailing the junctions and ensuring metals in contact are compatible, which a professional should confirm.
Is metal cladding good in coastal areas?
Some metals and coatings handle coastal salt air better than others, but corrosion exposure is higher there. Specialist advice on the right metal, coating and detailing is especially valuable near the coast.
