1. Introduction
In the past 48 hours, a surge in sustainable home design has spotlighted metal clad houses across North America, with architects increasingly specifying corten steel facades and zinc clad roofs for their durability and low environmental impact. As more homeowners explore modern, industrial-style exteriors, questions about installation, cost, and upkeep of metal cladding have spiked online.
If you’re considering a metal clad house—or already own one—this guide gives you clear, step-by-step instructions on how to install and maintain your metal exterior. Whether you’re working with corrugated steel facade panels, vertical standing seam metal siding, or even pac clad column covers, we’ve got you covered.
2. Understanding Metal Clad Meaning and Materials
Before diving into installation, it’s essential to grasp what ‘metal clad‘ actually means. The term ‘clad metal meaning’ refers to a composite material where a base metal (like mild steel plate) is bonded with a corrosion-resistant layer—such as stainless steel, copper, or zinc. This creates durable, long-lasting surfaces ideal for exteriors.
Common types include:
- Aluminum clad steel: Lightweight and rust-resistant, often used in metal clad siding.
- Corten steel plate: Forms a protective rust patina; popular for corten steel facade projects.
- Zinc metal siding: Self-healing surface that ages gracefully; great for zinc clad dormers or roofs.
- Copper siding: Offers a distinctive look and excellent longevity.
- PAC CLAD standing seam systems: Premium pre-finished options like PAC CLAD HWP or coping for clean architectural lines.
3. Step-by-Step Installation of a Metal Clad Wall
Installing a metal clad wall isn’t just about aesthetics—it’s about weatherproofing and structural integrity. Follow these steps:
3.1 Prepare the Substrate
Ensure your wall framing is level and sheathed with a moisture barrier. Use plywood or OSB rated for exterior use. Install furring strips if needed to create an air gap behind the cladding—this improves ventilation and prevents condensation.
3.2 Choose Your Cladding System
Decide between systems like exterior corrugated metal siding, vertical standing seam metal siding, or flat panel systems (e.g., corten steel siding). Measure your wall area carefully to minimize waste during metal sheet cutting.
3.3 Cut and Fit Panels
Use aviation snips or a metal shear to cut aluminum clad sheet or stainless steel metal plate to size. Always wear gloves and eye protection. For precise cuts on alloy plate or 6061 T6 aluminum plate, consider professional metal sheet cutting services.
3.4 Attach the Cladding
Start at the bottom and work upward. Secure panels using hidden fasteners for standing seam systems or exposed screws with neoprene washers for corrugated styles. Leave expansion gaps (typically 1/8 inch per 10 feet) to accommodate thermal movement.
4. Maintaining Your Metal Clad Exterior
Metal clad buildings are low-maintenance but not zero-maintenance. Here’s how to keep yours looking sharp:
- Rinse annually with water to remove dust and pollutants.
- For zinc or copper siding, avoid harsh cleaners—they disrupt natural patina formation.
- Inspect seams and fasteners yearly; tighten loose screws and replace corroded ones.
- Touch up scratches on colorbond standing seam or PAC CLAD products with manufacturer-approved paint.
5. Common Problems and Quick Fixes
Even the best metal clad house can face issues. Here’s how to troubleshoot:
5.1 Rust Spots on Steel Clad Surfaces
If you spot rust on a steel facade that isn’t corten, it likely means the protective coating was compromised. Sand the area lightly, apply a rust-inhibiting primer, and repaint with a matching finish.
5.2 Leaks Around Windows or Penetrations
Ensure all flashings (like PAC CLAD coping or custom trim) are properly sealed. Use high-quality sealant compatible with your metal type—silicone for stainless, polyurethane for aluminum.
5.3 Noise During Rain on Metal Clad Roof
A well-insulated roof assembly minimizes drumming. Add metal clad insulation beneath the decking or choose thicker gauge panels (e.g., 24-gauge instead of 29-gauge).
6. Cost Considerations
Corten siding cost varies widely—typically $8–$15 per square foot installed. Aluminum clad steel is more affordable ($5–$10/sq ft), while zinc clad roof systems can exceed $20/sq ft. Always get quotes from experienced contractors familiar with steel clad building techniques.
7. Conclusion
A metal clad house offers unmatched durability, modern style, and sustainability—especially when using materials like corten steel plate, zinc facade panels, or PAC CLAD standing seam roofing. By following this guide, you’ll ensure a professional-looking installation and extend the life of your investment for decades. Whether you’re building a metal clad shed or a full steel clad home, the right prep and maintenance make all the difference.
