1. Introduction
Just 24 hours ago, a major architectural firm in Portland unveiled a new residential project featuring a striking corten steel facade that’s already gone viral on design forums. The home showcases how modern metal clad exteriors blend durability with bold aesthetics—a trend accelerating across North America as homeowners seek weather-resistant, low-maintenance alternatives to traditional wood or vinyl siding.
If you’re considering upgrading to metal clad siding—or already have it and need maintenance tips—you’ve come to the right place. This guide breaks down exactly how to install, repair, and care for various types of metal cladding, including corrugated steel facade panels, vertical standing seam metal siding, zinc clad dormers, and more.
2. Understanding Metal Clad: What It Is and Why It Matters
Metal clad meaning refers to any exterior surface where a base material is covered or ‘clad’ with a layer of metal for protection, aesthetics, or performance. Clad metals can include aluminum clad steel, stainless clad aluminum, titanium clad sheets, or even copper nickel clad composites. These materials combine strength, corrosion resistance, and visual appeal.
Common applications include metal clad wall systems, metal clad roofs, metal clad sheds, and full metal clad buildings. Whether you’re using pac clad standing seam roof panels or exterior corrugated metal siding, knowing your metal clad type ensures proper installation and longevity.
3. Step-by-Step Guide to Installing Metal Clad Siding
3.1. Choose the Right Material
Start by selecting your preferred metal. Popular choices include:
- Corten steel siding (ideal for rustic, weathering looks; note: corten siding cost averages $8–$15/sq.ft)
- Zinc metal siding or zinc clad roof panels (self-healing patina, long lifespan)
- Aluminum clad sheet or aluminum diamond tread plate (lightweight, rust-proof)
- Colorbond standing seam or pac clad hwp (pre-finished, durable color options)
- Copper siding (premium look, ages beautifully)
For high-wind or coastal areas, consider stainless steel plate or 6061 T6 aluminum plate for added resilience.
3.2. Prepare the Wall Surface
Ensure your substrate is flat, dry, and structurally sound. Install a quality weather-resistant barrier (like housewrap) over sheathing. Add furring strips if needed to create an air gap—this improves drainage and reduces thermal bridging, especially when using metal clad insulation behind the panels.
3.3. Measure, Cut, and Handle Panels Safely
Use metal sheet cutting tools (e.g., aviation snips or a circular saw with a metal-cutting blade) to trim panels. Always wear gloves—edges can be sharp. For precision, mark cuts on the backside to avoid scratching visible surfaces.
3.4. Install Starting Strips and First Panel
Begin at the bottom corner. Attach a starter strip level and secure with corrosion-resistant fasteners. Slide the first panel into place, aligning it vertically. Use spacers to maintain consistent expansion gaps (typically 1/8 inch).
3.5. Continue Upward with Proper Overlap
For corrugated or standing seam systems, follow manufacturer specs for lap length. With vertical standing seam metal siding, clip systems often eliminate exposed fasteners—enhancing both looks and water resistance. Secure every 12–24 inches depending on wind load.
3.6. Finish Edges and Penetrations
Use pac clad coping for roof edges and pac clad column covers around posts. Seal around windows, vents, and doors with compatible flashing and sealant rated for metal movement.
4. Common Problems and How to Fix Them
4.1. Rust or Corrosion on Steel Cladding
Even clad steel can corrode if the coating is scratched. Clean affected areas, apply rust converter, then touch up with matching paint. For long-term protection, choose zinc-coated or stainless clad aluminum options.
4.2. Oil Canning (Wavy Appearance)
This occurs when panels aren’t properly supported. Add intermediate clips or reduce span distances between furring strips to minimize flexing.
4.3. Poor Insulation Performance
If your metal clad house feels drafty, check for missing insulation behind panels. Consider adding rigid foam or mineral wool with a vapor barrier. Aluminum clad pipe insulation can also help on exposed conduits.
4.4. Loose or Noisy Panels
Tighten fasteners—but don’t over-torque. Use neoprene washers to dampen sound and allow for thermal expansion.
5. Maintenance Tips for Longevity
Rinse your metal facade annually with mild soap and water. Avoid abrasive cleaners—they can damage protective coatings like chromium electroplating or gold coating finishes. Inspect seams and fasteners every spring, especially after storms.
For corten steel siding, let the natural patina develop—don’t paint it unless you want to halt oxidation. If you prefer a consistent look, opt for pre-rusted panels.
6. Conclusion
Metal clad siding offers unmatched durability, modern style, and minimal upkeep—making it a smart investment for any metal clad building. Whether you choose a zinc facade, corrugated steel facade, or pac clad standing seam system, proper installation and routine care ensure decades of performance. With trends leaning toward industrial-chic exteriors, now’s the perfect time to clad your home in metal.
