1. Introduction
Just 24 hours ago, the American Institute of Architects (AIA) released its 2024 Material Trends Report, highlighting a 37% surge in demand for sustainable, long-lasting exterior cladding—especially metal clad systems like corten steel facades and zinc clad roofs. With climate resilience and low maintenance topping client wishlists, understanding the nuances of metal clad options has never been more critical.
Whether you’re designing a steel clad house, renovating a metal clad shed, or specifying materials for a commercial metal clad building, not all clad metals are created equal. In this guide, we’ll compare real-world performance, costs, and aesthetics of today’s top metal clad types—so you can make smarter, future-proof choices.
2. What Does Metal Clad Mean?
The term metal clad (or metalclad) broadly refers to structures or components covered with a layer of metal for protection, durability, or visual appeal. This includes everything from metal clad wall panels and metal clad roofs to specialized products like aluminum clad pipe insulation or metal clad electrical wire.
Clad metal meaning hinges on the concept of layering: a base material—often steel, wood, or insulation—is bonded or coated with a more resilient or decorative metal. Common combinations include aluminum clad steel, stainless clad aluminum, and titanium clad plates used in aerospace or chemical processing.
3. Popular Metal Clad Types for Exteriors
When it comes to building exteriors, your choice of metal clad siding or facade dramatically impacts both longevity and curb appeal. Here’s how top options stack up:
- Corten steel facade: Known for its rust-like patina, corten steel siding offers unmatched weather resistance without painting. Corten siding cost runs $8–$15/sq.ft., making it pricier upfront but low-maintenance long-term.
- Zinc facade: Elegant and self-healing, zinc metal siding develops a soft gray patina. A zinc clad roof or zinc clad dormer lasts 80+ years. It’s ideal for standing seam facade systems and pairs well with modern architecture.
- Copper siding: Timeless and antimicrobial, copper ages to a green verdigris. Though costly ($12–$20/sq.ft.), it’s prized for heritage projects and high-end metal clad houses.
- Exterior corrugated metal siding: Affordable and industrial-chic, corrugated steel facade systems (often in Colorbond or PAC Clad finishes) are popular for sheds, barns, and urban lofts. PAC Clad standing seam and vertical standing seam metal siding offer sleek alternatives.
4. Structural and Industrial Clad Metals
Beyond aesthetics, clad metals play vital roles in infrastructure and manufacturing. Aluminum clad stainless steel and stainless clad aluminum combine corrosion resistance with strength—common in food processing and marine environments.
For high-stress applications, alloy clad plates like 2024-T3 clad aluminum or 7075-T6 clad are used in aviation. In heavy industry, chrome carbide overlay plates or Inconel weld overlay protect against abrasion and extreme heat.
Even electrical systems rely on metal clad wire—such as aluminum clad steel wire or Cu clad wire—for grounding and durability in commercial buildings. Note: metal clad electrical wire can be surface-mounted and used outdoors when rated for wet locations.
5. Comparing Performance and Cost
Not all metal clad solutions deliver the same ROI. Corten steel plate requires no painting but may stain adjacent surfaces during weathering. Zinc and copper are low-maintenance but sensitive to acidic rain in polluted areas.
Aluminum clad sheet (or aluminium clad sheet) is lightweight and corrosion-resistant, perfect for PAC Clad column covers or coping. Meanwhile, steel plate options—like 1/4 steel plate or 3/16 metal plate—are foundational for structural frames but often need zinc coated or electroplating treatments (e.g., chromium electroplating) for exterior use.
For budget-conscious builds, exterior corrugated metal siding or metal weatherboard in Colorbond finishes offer style without the premium price. PAC Clad HWP (High-Weather Performance) systems provide enhanced durability for coastal zones.
6. Installation and Compatibility Tips
When installing a metal clad roof or wall, always consider thermal expansion—especially with aluminum or copper. Use compatible fasteners to avoid galvanic corrosion (e.g., don’t pair untreated steel with aluminum).
For standing seam systems like Colorbond standing seam or PAC Clad standing seam roof, ensure proper underlayment and ventilation to prevent condensation. And remember: a metal clad building still needs insulation—metal clad insulation with aluminum-faced barriers boosts energy efficiency.
7. Conclusion
From corten steel siding to zinc clad dormers and aluminum clad pipe insulation, the metal clad universe offers tailored solutions for nearly every architectural and industrial need. By matching material properties to your climate, budget, and design goals, you’ll create structures that are not just beautiful—but built to last decades. Whether you’re sourcing 6061-T6 aluminum plate or specifying a stainless steel facade, understanding clad metal meaning and real-world performance is your best tool for success.
