1. Introduction
Just 24 hours ago, a major architectural firm in Chicago unveiled a new downtown office tower featuring a striking corten steel facade—a bold example of how metal clad design continues to dominate modern construction. As sustainability and durability drive building trends in 2024, metal clad systems are surging in popularity across residential, commercial, and industrial projects.
But what exactly does ‘metal clad‘ mean? And why are architects, builders, and engineers increasingly choosing metal clad solutions? In this guide, we’ll unpack the metal clad meaning, explore its many forms—from metal clad siding to clad steel—and highlight the top applications you should know about.
2. What Is Metal Clad?
The term ‘metal clad‘ (sometimes written as ‘metalclad’) broadly refers to any structure, component, or surface that is covered or reinforced with a layer of metal. This technique—also known as cladding—combines the strength, corrosion resistance, or aesthetic appeal of one metal with the structural or cost benefits of another.
Clad metal meaning isn’t limited to buildings. It spans electrical wiring (like metal clad electrical wire), piping (aluminum clad pipe insulation), and even cookware. In construction, however, ‘metal clad’ most commonly describes exterior finishes such as metal clad walls, roofs, and facades.
3. Popular Types of Metal Clad Building Materials
3.1. Steel and Corten Steel Options
Steel clad systems are among the most durable choices for modern exteriors. A corten steel facade develops a rust-like patina over time, offering both weather resistance and a distinctive industrial look. Corten steel siding cost varies but is often justified by its longevity and low maintenance—making steel clad houses increasingly trendy in urban and rural settings alike.
- Corten steel plate is ideal for sculptural elements and accent walls
- Corrugated steel facade panels add texture and visual rhythm
- Steel plate (including 1/4 steel plate or 3/16 steel plate) is used for structural backing or decorative cladding
3.2. Zinc and Copper Cladding
Zinc clad roofs and zinc metal siding are prized for their self-healing properties and sleek, matte finish. A zinc clad dormer or standing seam facade using zinc offers elegance with minimal upkeep. Similarly, copper siding ages gracefully into a green patina, often seen on high-end metal clad houses.
3.3. Aluminum and Colorbond Systems
Aluminum clad steel—whether as aluminum clad sheet, aluminum clad wire, or vertical standing seam metal siding—is lightweight and corrosion-resistant. Products like Colorbond standing seam and PAC Clad HWP (High-Weather Performance) systems are widely used for metal clad roofs and wall panels. PAC Clad coping and column covers also provide seamless architectural detailing.
4. Industrial and Technical Applications of Clad Metals
Beyond architecture, clad metals play a critical role in engineering and manufacturing. Clad steel often combines stainless steel with carbon steel for cost-effective corrosion resistance—common in chemical plants and marine environments.
Examples include aluminum clad stainless steel (or its inverse, stainless clad aluminum), titanium clad components for aerospace, and copper nickel clad alloys for heat exchangers. Even metal clad wire—such as CU clad wire or aluminum clad steel wire—is used in electrical and telecommunications infrastructure.
Specialized products like 2024 T3 clad or 7075 T6 clad aluminum plates are standard in aviation, while alloy clad materials like Inconel 625 weld overlay protect high-stress industrial surfaces.
5. Metal Clad in Residential and Commercial Construction
Metal clad buildings are no longer just utilitarian sheds. Today’s metal clad shed or steel clad building can feature premium finishes like perforated plate accents, diamond plate sheet detailing, or even brass plates for engraving on entryways.
Homeowners are embracing metal weatherboard and exterior corrugated metal siding for their modern aesthetic and resilience. A steel clad house might use stainless steel metal plate for trim or base plates, while aluminum diamond tread plate adds slip resistance to porches or ramps.
For insulation, metal clad insulation wraps pipes and ducts, with aluminum clad pipe insulation being a common choice in HVAC systems.
6. Choosing the Right Metal Clad Type
Selecting the right metal clad type depends on climate, budget, and design goals. For coastal areas, 316 stainless steel plate or zinc-coated options resist salt corrosion. In fire-prone zones, non-combustible steel plate or boiler plate steel adds safety.
Popular sheet and plate materials include:
- 6061 T6 aluminum plate for structural frames
- 304L or 316L stainless steel plate for high-corrosion areas
- Mild steel plate for cost-effective backing
- Aluminum 5052 sheet for marine applications
Always verify local codes—especially when using metal clad electrical wire in commercial buildings, as regulations vary by state (e.g., Pennsylvania permits it with proper grounding).
7. Maintenance and Longevity
One reason metal clad systems are trending is their low maintenance. Corten siding cost may be higher upfront, but it eliminates painting needs. Zinc and copper develop protective patinas. Aluminum and Colorbond finishes resist fading for decades.
Regular cleaning with mild soap and water is usually sufficient. Avoid abrasive tools on delicate finishes like chrome metal or electroplating surfaces such as chromium plate or gold coating.
8. Sustainability and Future Trends
Metal clad materials are highly recyclable—stainless steel plate, aluminum plate, and even brass metal plate can be reused indefinitely. This aligns with green building standards like LEED.
Innovations like electroless nickel plating and zinc nickel alloy coatings are enhancing durability without toxic byproducts. Expect more hybrid systems, like PAC Clad standing seam roofs paired with solar panels, to emerge in 2024.
9. Common Misconceptions
Many assume ‘metal clad’ means cold, industrial looks—but modern options like vertical standing seam metal siding or zinc clad dormers offer warmth and texture. Others confuse metal clad wire with armored cable, though both serve protective electrical functions.
Also, not all ‘clad’ metals are the same: aluminum clad steel differs from stainless clad aluminum in performance and application. Always check material specs like ASTM A387 for alloy plate standards.
10. Conclusion
From the sleek lines of a corten steel facade to the hidden strength of clad steel in pipelines, metal clad is far more than just a surface treatment—it’s a smart, sustainable, and stylish solution across industries. Whether you’re building a metal clad house, specifying a zinc facade, or selecting clad metals for engineering, understanding your options ensures durability, beauty, and value for years to come.
