1. Introduction
Just 24 hours ago, a new eco-conscious housing development in Portland made headlines for using corten steel siding and zinc clad roofs across all its units—showcasing how metal clad systems are becoming the go-to choice for modern, durable, and visually striking architecture. This surge in popularity has sparked renewed interest in understanding what ‘metal clad’ really means.
If you’ve heard terms like metal clad wall, metal clad roof, or even metal clad electrical wire but aren’t sure how they connect, you’re not alone. ‘Metal clad’ is a broad term that spans construction, manufacturing, and engineering—and it’s more versatile than you might think.
2. What Does ‘Metal Clad’ Mean?
At its core, the metal clad meaning refers to a composite material or structure where one metal (or alloy) is bonded to another for enhanced performance. This process—known as cladding—can improve corrosion resistance, strength, aesthetics, or thermal properties.
The clad metal meaning isn’t limited to buildings. It applies to everything from stainless clad aluminum cookware to aluminum clad steel wire used in power transmission. In construction, however, ‘metal clad‘ most often describes exterior surfaces like walls, roofs, and facades.
3. Metal Clad in Architecture and Construction
3.1. Metal Clad Walls and Facades
Metal clad walls are increasingly popular in both residential and commercial design. Options like corrugated steel facade, standing seam facade, and corten steel facade offer durability and a sleek industrial look.
Designers love corten steel siding for its weathering properties—it develops a rust-like patina that protects the underlying steel. Meanwhile, zinc metal siding and copper siding provide timeless elegance with minimal maintenance.
- Corten steel siding cost varies but typically ranges from $8 to $15 per square foot, depending on finish and supplier.
- Zinc clad dormer and zinc clad roof installations are prized for longevity—some last over 100 years.
3.2. Metal Clad Roofs
A metal clad roof isn’t just functional—it’s stylish. Systems like colorbond standing seam and pac clad standing seam roof combine weather resistance with clean lines.
Vertical standing seam metal siding doubles as both wall and roof cladding in minimalist designs. Brands like PAC Clad also offer accessories like pac clad coping and pac clad column covers for seamless integration.
3.3. Metal Clad Houses and Sheds
From modern steel clad house designs to backyard metal clad sheds, homeowners are embracing metal for its resilience and low upkeep. A steel clad building can withstand extreme weather, resist pests, and reduce long-term maintenance costs.
Exterior corrugated metal siding remains a favorite for its rugged charm and affordability. And for those seeking a classic look with modern performance, metal weatherboard offers a nostalgic yet durable alternative.
4. Industrial and Technical Uses of Clad Metals
4.1. Clad Metals in Manufacturing
Beyond architecture, clad metals play a critical role in heavy industry. Aluminum clad stainless steel and stainless clad aluminum combine the best properties of both metals—lightweight strength with corrosion resistance.
Titanium clad and copper nickel clad materials are used in chemical processing and marine environments where extreme durability is essential. Alloy clad options like 2024 T3 clad and 7075 T6 clad are common in aerospace for their high strength-to-weight ratios.
4.2. Metal Clad Electrical and Insulation Systems
Metal clad electrical wire—often called MC cable—is widely used in commercial buildings for its fire resistance and mechanical protection. Aluminum clad wire and cu clad wire are variants designed for specific conductivity or shielding needs.
In piping, aluminum clad pipe insulation helps maintain temperature and prevent condensation. Similarly, metal clad insulation is used in HVAC and industrial systems to enhance efficiency and safety.
5. Common Materials and Plates Used in Metal Cladding
The backbone of many metal clad systems is the metal plate. Whether it’s mild steel plate, stainless steel plate, or aluminum plate, these substrates determine performance and appearance.
Popular choices include:
- Corten steel plate for weathering facades
- 316 stainless steel plate for marine-grade applications
- Aluminum 6061 T6 plate for structural components
- Diamond plate steel and aluminum diamond tread plate for slip-resistant surfaces
Thickness matters too—common gauges include 1/8 inch steel plate, 3/16 metal plate, and 1/4 metal plate, each suited to different load and environmental demands.
Processes like electroplating, chromium electroplating, and electroless nickel coating further enhance surface properties. Gold coating and nickel sulfamate plating are used in electronics and precision instruments.
6. Sustainability and Future Trends
With rising demand for sustainable building materials, metal clad systems shine. Most are 100% recyclable, require little maintenance, and have long lifespans—key factors in green building certifications like LEED.
Recent innovations include pac clad hwp (high-performance wall panels) and inconel weld overlay for extreme environments. Architects are also experimenting with perforated plate and alloy checker plate to add texture and airflow to facades.
7. Conclusion
So, what is metal clad? It’s a smart fusion of materials that delivers strength, style, and sustainability across countless applications. Whether you’re building a steel clad inc commercial space, installing a zinc facade, or running aluminum clad steel wire through a wall, understanding the versatility of clad metals opens up a world of possibilities.
