1. Introduction
Just 24 hours ago, global architecture firm Foster + Partners unveiled a new sustainable office tower in Copenhagen featuring a striking zinc clad dormer and vertical standing seam metal siding—a bold move that’s reigniting interest in high-performance metal cladding systems. As cities push for greener, longer-lasting exteriors, understanding the nuances of metal clad materials has never been more critical.
Whether you’re specifying a steel clad house, designing a commercial metal clad building, or selecting exterior corrugated metal siding for a shed, the choices matter. Not all ‘metal clad’ solutions are created equal. In this deep-dive listicle, we break down seven major types of metal clad systems, comparing their real-world performance, costs, and ideal use cases.
2. Corten Steel Facade: Rust That Works for You
Corten steel siding is beloved for its self-protecting rust patina that eliminates the need for painting. This weathering steel forms a stable oxide layer that shields the base metal—ideal for dramatic, low-maintenance exteriors.
However, corten siding cost remains higher than standard options, averaging $8–$12 per sq. ft. installed. It’s also unsuitable for humid coastal zones where salt accelerates corrosion beyond control. Still, for urban lofts or artistic installations, a corten steel facade delivers unmatched character.
- Best for: Sculptural architecture, industrial-style homes
- Watch out for: Staining on adjacent surfaces during initial weathering phase
3. Zinc Metal Siding and Roofing: The Quiet Performer
Zinc clad roof and zinc facade systems offer exceptional longevity—up to 100 years—with minimal upkeep. Naturally antimicrobial and 100% recyclable, zinc develops a soft gray patina over time that architects prize for its subtlety.
A zinc clad dormer or full zinc metal siding installation typically costs $15–$20 per sq. ft., placing it in the premium tier. But its fire resistance, non-combustibility, and compatibility with rainwater harvesting make it a favorite in EU green building codes.
- Best for: High-end residential, institutional buildings
- Bonus: Often used with pac clad standing seam profiles for seamless aesthetics
4. Copper Siding: Timeless but Pricey
Copper siding ages gracefully from shiny penny-red to deep green verdigris. While stunning, it’s among the most expensive metal clad options—often exceeding $25 per sq. ft.
Its main drawback? Theft risk due to scrap value. Yet, in historic restorations or luxury builds, copper remains irreplaceable. It’s also highly malleable, perfect for curved metal clad wall elements.
- Best for: Heritage projects, boutique retail facades
- Pro tip: Pair with stainless clad aluminum substrates to reduce material use without sacrificing appearance
5. Aluminum Clad Systems: Lightweight and Versatile
From aluminum clad steel wire to aluminum clad sheet panels, this category dominates modern cladding. Aluminum’s light weight, corrosion resistance, and ease of fabrication make it ideal for everything from pac clad column covers to metal weatherboard.
Colorbond standing seam and pac clad hwp (horizontal wall panel) systems often use pre-painted aluminum sheets, offering vibrant, fade-resistant finishes. Aluminum clad pipe insulation also leverages these properties for HVAC efficiency.
Crucially, aluminum clad stainless steel and stainless clad aluminum hybrids combine strength with surface durability—common in marine and chemical environments.
- Best for: High-rises, coastal builds, modular construction
- Note: Avoid galvanic contact with untreated steel to prevent corrosion
6. Steel Clad Solutions: Strength Meets Style
Steel clad inc products—like corrugated steel facade panels or standing seam siding—are workhorses of commercial construction. Using mild steel plate or corten steel plate, they deliver structural integrity plus design flexibility.
Options range from 1/8 inch steel plate for lightweight siding to thick steel plate for blast-resistant walls. Stainless steel plate grades (like 316 or 304L) add corrosion resistance for harsh climates.
Boiler plate steel and carbon steel plate remain popular for metal clad sheds and industrial enclosures due to affordability and availability near local suppliers (‘steel plate near me’ searches are up 32% this year).
- Best for: Warehouses, agricultural buildings, urban infill
- Trend: Perforated plate and diamond plate steel sheets add texture and function
7. Specialty Alloy Clad: The Future Frontier
Beyond traditional metals, alloy clad systems are gaining traction. Think 7075 T6 clad aluminum for aerospace-inspired facades or inconel 625 weld overlay for extreme environments.
Copper nickel clad and cupro nickel clad composites resist biofouling—ideal for waterfront structures. Meanwhile, titanium clad and nickel sulfamate-plated plates serve niche roles in labs and cleanrooms.
Even electrical applications benefit: metal clad electrical wire (including cu clad wire and aluminum clad steel wire) uses layered conductors for enhanced safety and conductivity.
- Best for: Labs, offshore platforms, high-tech facilities
- Emerging: Electroless nickel and chromium electroplating enhance wear resistance on metal nameplates and base plates
8. Conclusion
Choosing the right metal clad type isn’t just about looks—it’s about lifecycle cost, climate response, and sustainability. From the raw drama of a corten steel plate to the sleek reliability of a pac clad coping system, each material tells a story. As seen in Copenhagen’s latest build, the future of architecture lies in smart cladding choices that balance beauty, performance, and planet.
