1. Introduction
Just 24 hours ago, a major architectural firm in Chicago unveiled a new mixed-use development featuring a striking corrugated steel facade combined with vertical standing seam metal siding—showcasing how metal clad design is surging in popularity for its durability, sustainability, and modern aesthetic. Homeowners and builders alike are increasingly turning to metal clad walls for everything from steel clad houses to commercial metal clad buildings.
But if you’re new to working with metal cladding, you might be wondering: How do you actually install it? And how do you keep it looking great for decades? This guide breaks down the entire process—from choosing the right clad metal meaning for your project to troubleshooting common installation issues.
2. Choosing the Right Metal Clad Material
Not all metal clad systems are the same. The term ‘clad metals‘ refers to composite materials where a base metal (like steel or aluminum) is bonded with a corrosion-resistant layer—such as zinc, copper, or stainless steel. Popular options include:
- Corten steel siding: Rustic, self-weathering, and ideal for modern exteriors (though corten siding cost can be higher).
- Zinc metal siding or zinc clad roof: Long-lasting with a soft gray patina that evolves over time.
- Aluminum clad steel: Lightweight, corrosion-resistant, and often used in standing seam siding.
- Copper siding: Premium look with natural aging; great for accent walls or zinc clad dormers.
- Colorbond standing seam or PAC CLAD standing seam roof panels: Pre-finished, low-maintenance, and widely available.
For residential projects like a metal clad house or shed, exterior corrugated metal siding offers affordability and quick installation. Commercial builds might opt for a steel facade or stainless clad aluminum for enhanced performance.
3. Preparing the Wall Substructure
Before installing any metal clad wall, ensure your substructure is sound. Use pressure-treated wood or metal studs with proper spacing (typically 16–24 inches on center). Install a high-quality weather-resistant barrier (WRB) like housewrap to prevent moisture intrusion behind the cladding.
Check local building codes—especially if you’re using metal clad electrical wire or aluminum clad pipe insulation nearby. Your wall must support the weight of materials like thick steel plate or stainless steel metal plate without sagging.
4. Installing the Metal Cladding
Follow these steps for a clean, watertight installation:
- Start at the bottom: Install a starter strip or PAC CLAD coping along the base to direct water away.
- Use proper fasteners: Stainless steel or coated screws compatible with your cladding type (e.g., aluminum clad sheet vs. corten steel plate).
- Maintain expansion gaps: Metal expands and contracts with temperature. Leave small gaps at joints or use slotted holes for vertical standing seam metal siding.
- Overlap panels correctly: For corrugated steel facade or metal weatherboard, ensure overlaps follow the manufacturer’s specs—usually 1–2 corrugations.
- Seal penetrations: Around windows, doors, or PAC CLAD column covers, use compatible sealants to prevent leaks.
Pro tip: If you’re working with PAC CLAD HWP (High Wall Panel) systems, follow the manufacturer’s clip spacing guidelines to avoid oil-canning (visible ripples in flat panels).
5. Common Problems and How to Fix Them
Even the best metal clad installations can face issues. Here’s how to troubleshoot:
- Rust spots on clad steel: Usually from scratches exposing the base metal. Touch up with matching paint or let corten steel develop its protective patina naturally.
- Loose panels: Caused by improper fastening or wind uplift. Re-secure with longer screws into solid framing.
- Condensation behind cladding: Improve ventilation or add metal clad insulation with a vapor barrier.
- Fading or chalking: Common with lower-grade finishes. Choose PVDF-coated products like PAC CLAD or Colorbond for UV resistance.
Avoid using abrasive cleaners on zinc facade or copper siding—stick to mild soap and water.
6. Maintenance Tips for Longevity
Metal clad walls are low-maintenance but not zero-maintenance. Inspect annually for:
- Loose fasteners or damaged seams
- Debris buildup in corrugations (especially on metal clad roofs)
- Signs of galvanic corrosion (e.g., where aluminum clad steel contacts untreated steel)
Clean gently with a soft brush and rinse. For stainless plate or brass metal plate accents, use manufacturer-recommended cleaners to preserve luster.
7. Conclusion
Whether you’re building a sleek steel clad building or updating a backyard metal clad shed, understanding how to properly install and care for your metal clad wall ensures decades of performance and curb appeal. From choosing between aluminum clad stainless steel and titanium clad panels to mastering the nuances of standing seam facade installation, this guide gives you the practical know-how to succeed. Remember: the key to a great metal clad project lies in preparation, proper materials, and proactive maintenance.
