1. Introduction
In the past 48 hours, architects and builders across North America have seen a spike in demand for sustainable, fire-resistant, and long-lasting exterior finishes—prompted by new wildfire resilience guidelines in California and Oregon. Among the top solutions gaining traction? Metal clad siding. From sleek corten steel facades to classic corrugated steel and modern colorbond standing seam panels, metal cladding offers both aesthetic appeal and rugged durability.
But if you’re new to working with metal clad walls or planning a renovation on your metal clad house, you might be wondering: How do I actually install it correctly—and keep it looking great for decades? This guide breaks it all down in simple, actionable steps.
2. Understanding Metal Clad Meaning and Types
First, let’s clarify what ‘metal clad‘ really means. The term ‘clad metal meaning’ refers to materials made by bonding two or more metals together—like aluminum clad steel or stainless clad aluminum—to combine strength, corrosion resistance, and cost-efficiency. Common types include:
- Corten steel siding (ideal for rustic-modern looks and self-weathering rust patina)
- Zinc metal siding (low maintenance, elegant gray finish that ages beautifully)
- Copper siding (premium option with natural green patina over time)
- Exterior corrugated metal siding (classic industrial look, often used on sheds and cabins)
- Vertical standing seam metal siding (clean lines, excellent water shedding)
- Aluminum clad sheet or steel plate options for custom applications
Whether you’re building a metal clad shed, a steel clad house, or upgrading a commercial metal clad building, choosing the right clad metal type is crucial for performance and longevity.
3. Step-by-Step Installation Guide
Installing metal clad siding isn’t DIY-friendly for beginners, but with proper prep, it’s manageable for experienced handymen or contractors. Here’s how to do it right:
3.1. Prepare the Wall Surface
Ensure your sheathing is flat, dry, and covered with a weather-resistant barrier (like Tyvek). Install vertical furring strips if using rainscreen systems—this creates airflow behind the metal to prevent moisture buildup.
3.2. Measure and Cut Panels
Use metal snips or a circular saw with a metal-cutting blade to trim panels. Always wear safety goggles. For precision, mark cuts on aluminum diamond tread plate or stainless steel plate using a straight edge. Remember: leave expansion gaps (about 1/8 inch) between panels to handle thermal movement.
3.3. Start at the Bottom
Begin installation at the lowest point of the wall. Use a level line as a guide. Attach starter clips or base flashing first—many pros use pac clad coping or pac clad hwp trim pieces for clean transitions.
3.4. Secure Panels Properly
Fasten panels with concealed clips (for standing seam) or exposed screws with neoprene washers (for corrugated styles). Never over-tighten—this can warp thin-gauge metal. For pac clad standing seam roofs or facades, follow manufacturer specs for clip spacing.
3.5. Handle Corners and Penetrations
Use pre-formed corner trims or custom-bent pieces from aluminum clad stainless steel stock. Seal around windows, vents, and pipes with compatible sealants. For pipe penetrations, aluminum clad pipe insulation sleeves help maintain thermal and moisture barriers.
4. Common Problems and Fixes
Even the best-installed metal clad systems can face issues. Here’s how to troubleshoot them:
- Rust spots on corten steel before full patina forms: Wait—it’s part of the process. Avoid painting or sealing unless specified.
- Oil-canning (waviness in large flat panels): Minimize by using narrower panel widths or adding stiffeners.
- Scratches on stainless plate or aluminum tread plate: Light marks can be buffed; deep ones may require panel replacement.
- Loose fasteners: Re-tighten or replace with longer screws anchored into framing.
- Corrosion at cut edges: Apply zinc-rich primer or use factory-coated edges when possible.
5. Maintenance Tips for Longevity
Metal clad siding is low-maintenance, but not zero-maintenance. To extend its life:
- Rinse annually with water to remove salt, pollen, or pollution buildup—especially near coastal areas.
- Inspect seals and fasteners every 2–3 years.
- Avoid abrasive cleaners on copper or zinc facades—they disrupt natural aging.
- For steel clad inc or alloy-clad surfaces, touch up scratches with matching paint pens if the coating is compromised.
6. Cost Considerations
Wondering about corten steel siding cost? It typically ranges from $7 to $12 per sq. ft. installed—higher than vinyl but comparable to high-end wood. Zinc clad dormer or pac clad column covers add architectural flair but increase budget. Always get quotes based on your local steel plate price and labor rates.
7. Conclusion
Metal clad siding blends industrial strength with modern design—making it perfect for everything from a minimalist steel facade to a rugged metal clad shed. By choosing the right clad metals, installing with care, and performing light upkeep, your metal clad wall will stand strong for 50+ years. Whether you opt for a zinc clad roof, corrugated steel facade, or vertical standing seam metal siding, this guide gives you the foundation to succeed.
