1. Introduction
Just 24 hours ago, global architecture firm Foster + Partners unveiled a new eco-campus in Copenhagen featuring a striking corten steel facade paired with vertical standing seam metal siding—a bold statement in sustainable design that’s reigniting interest in metal clad building systems. This move underscores a growing trend: architects and builders are increasingly turning to clad metals not just for durability, but for their evolving aesthetic and environmental credentials.
But what exactly does ‘metal clad’ mean? And how do different types stack up against each other in real-world applications? Whether you’re considering a metal clad house, a steel clad shed, or even aluminum clad pipe insulation, understanding the nuances between options is key to making smart, long-lasting choices.
2. Understanding Metal Clad: Meaning and Basics
The term ‘metal clad‘ (sometimes written as ‘metalclad’) broadly refers to a composite material where one metal is bonded—mechanically or metallurgically—to another. This process enhances performance by combining the strengths of both materials. For example, stainless clad aluminum offers corrosion resistance from the stainless layer while retaining aluminum’s light weight.
Clad metal meaning isn’t limited to construction. You’ll find metal clad wire in electrical systems, aluminum clad steel wire in fencing, and even cu clad wire in electronics. But in architecture, ‘metal clad’ most often describes exterior surfaces—like a metal clad wall, metal clad roof, or metal facade.
3. Popular Types of Metal Cladding in Architecture
3.1 Corten Steel Facade and Siding
Corten steel siding has surged in popularity thanks to its weathering properties—it forms a stable rust-like appearance that eliminates the need for painting. A corten steel facade delivers industrial-chic aesthetics and exceptional longevity, though corten siding cost remains higher than alternatives. Expect to pay a premium for corten steel plate, especially in custom thicknesses like 1/4 steel plate or 3/16 metal plate.
3.2 Zinc and Copper Cladding
Zinc metal siding and copper siding offer timeless elegance with natural patinas that evolve over decades. A zinc clad roof or zinc clad dormer resists corrosion beautifully, while copper siding develops a distinctive green verdigris. Both are low-maintenance but come with high upfront costs. Zinc facade systems often use standing seam profiles for clean lines, while copper is favored for intricate detailing.
3.3 Aluminum and Steel Systems
Aluminum clad sheet and aluminum clad steel dominate commercial projects due to their light weight and recyclability. Colorbond standing seam and PAC Clad HWP (High-Performance) systems—like PAC Clad standing seam roof or PAC Clad column covers—are engineered for extreme weather resistance. Steel clad options, including corrugated steel facade and exterior corrugated metal siding, provide rugged durability ideal for metal clad sheds or industrial buildings.
4. Performance Comparison: Strengths and Trade-offs
When choosing between clad metals, consider climate, budget, and design goals. Corten steel excels in dry climates but may stain adjacent surfaces in wet zones. Zinc performs well in coastal areas but dents more easily than steel. Aluminum won’t rust but can corrode in alkaline environments.
- Corten steel siding cost: High initial investment, minimal maintenance
- Zinc clad roof: Moderate to high cost, excellent lifespan (80+ years)
- Aluminum clad steel: Affordable, lightweight, but less impact-resistant
- Copper siding: Premium pricing, unmatched longevity and beauty
For structural backing, builders often pair cladding with robust substrates like mild steel plate, carbon steel plate, or stainless steel plate. Thicker options—such as 1/8 inch steel plate or 3/16 steel plate—are common in base plates or load-bearing elements.
5. Beyond Facades: Other Metal Clad Applications
Metal clad isn’t just skin-deep. In piping, aluminum clad pipe insulation improves thermal efficiency. In electrical work, metal clad electrical wire (often armored) meets code requirements in commercial settings like Pennsylvania, where surface-mounted MC cable is permitted with proper fittings.
Industrial sectors rely on specialized clad metals too: titanium clad for chemical reactors, nickel brass clad copper for marine hardware, and alloy clad sheets like 2024-T3 clad or 7075-T6 clad for aerospace. Even boiler plate steel can be enhanced with chrome carbide overlay for wear resistance.
6. Installation and Material Sourcing Tips
Whether you’re installing vertical standing seam metal siding or rendering a metal cladding wall, precision matters. Use compatible fasteners to avoid galvanic corrosion—especially when mixing metals like aluminum and steel. For DIYers, pre-finished products like PAC Clad coping or colorbond panels simplify the process.
When sourcing materials, search for ‘steel plate near me’ or ‘aluminum sheet for sale’ to compare local pricing. Grades matter: 316 stainless steel plate outperforms 304 in salty air, while 6061-T6 aluminum plate offers superior strength for structural uses. Don’t overlook finishes—diamond plate steel, perforated plate, or aluminum tread plate add slip resistance and visual texture.
7. Conclusion
From the sleek steel facade of a downtown office to the rustic charm of a corten steel siding home, metal clad systems blend form, function, and future-readiness. Understanding the differences between clad metals—whether you’re comparing zinc vs. copper, evaluating corten siding cost, or selecting the right steel plate thickness—ensures your project stands the test of time. As sustainability drives innovation, expect clad metals to play an even bigger role in the buildings of tomorrow.
