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 sparking conversations across design forums. The home uses vertical standing seam metal siding paired with zinc clad dormers—a perfect example of how modern builders are embracing metal clad exteriors for both aesthetics and durability. If you’re considering a metal clad house or need to repair an existing one, you’re not alone. Metal cladding is surging in popularity thanks to its weather resistance, minimal upkeep, and contemporary appeal.
But what exactly does ‘metal clad‘ mean? In simple terms, metal clad refers to any building surface—wall, roof, or structure—covered with sheets or panels of metal. This includes everything from corrugated steel facade systems to aluminum clad sheet siding and copper siding accents. Whether you’re working with clad steel, stainless clad aluminum, or even titanium clad panels, proper installation and maintenance are key to longevity.
2. Choosing the Right Metal Clad Material
Not all metal clad siding is created equal. Your choice depends on climate, budget, and desired look. Here’s a quick breakdown of popular options:
- Corten steel siding: Rustic, self-protecting finish; ideal for modern industrial designs. Note: corten siding cost can be higher upfront but saves on painting.
- Zinc metal siding: Naturally patinas over time; excellent for coastal areas due to corrosion resistance.
- Colorbond standing seam: Pre-painted Australian steel with UV and fade resistance—great for metal clad roofs and walls.
- Exterior corrugated metal siding: Budget-friendly and easy to install; often used on metal clad sheds or accent walls.
- Copper siding: Premium option with rich aging characteristics; pairs well with pac clad column covers for high-end finishes.
Also consider alloy clad options like 2024-T3 clad or 7075-T6 clad if structural strength matters. For insulation, don’t overlook metal clad insulation wraps, especially when using aluminum clad pipe insulation in mixed-material builds.
3. Step-by-Step Installation Guide
Installing metal clad wall panels correctly prevents leaks, warping, and premature wear. Follow these steps:
3.1 Prepare the Substrate
Ensure your wall framing is level and sheathed with a moisture barrier (like housewrap). Never attach metal directly to bare wood or concrete without a drainage plane.
3.2 Measure and Cut Panels
Use aviation snips or a metal shear for clean cuts. For thicker materials like 1/4 steel plate or corten steel plate, a plasma cutter may be needed. Always wear safety gear—metal edges are sharp!
3.3 Install Starter Strips and Flashing
Begin at the bottom. Use pac clad coping or compatible flashing at transitions (e.g., where wall meets roof). This directs water away and prevents infiltration.
3.4 Attach Panels Properly
Use corrosion-resistant fasteners designed for your metal type. For vertical standing seam metal siding, clip systems (like snap clad clips) allow thermal movement. Never over-tighten—metal expands and contracts with temperature changes.
3.5 Seal Joints and Penetrations
Apply butyl tape or silicone sealant rated for metal at seams, around windows, and where pipes penetrate. This is critical for a watertight metal clad building envelope.
4. Common Problems and Fixes
Even the best-installed metal clad siding can face issues. Here’s how to troubleshoot:
- Rust spots on steel facade: Caused by scratches exposing raw metal. Sand lightly and apply a matching touch-up paint or rust converter.
- Oil-canning (waviness): Often due to improper panel support spacing. Add intermediate clips or braces behind affected areas.
- Noise during rain: A common complaint with metal clad roofs. Install insulation or use a standing seam system with hidden fasteners to dampen sound.
- Galvanic corrosion: Happens when dissimilar metals (e.g., aluminum clad steel next to copper) contact in wet conditions. Always use dielectric separators or compatible alloys like stainless clad aluminum.
5. Maintenance Tips for Longevity
Metal clad exteriors are low-maintenance but not zero-maintenance. Every 1–2 years:
- Rinse with a garden hose to remove dust and pollutants.
- Inspect fasteners for loosening—especially after storms.
- Check sealants around windows and joints; reapply if cracked.
- For zinc clad roof or copper siding, avoid pressure washing—it can strip the natural patina.
If you have a steel clad house near coastal zones, rinse more frequently to prevent salt buildup. And never use abrasive cleaners on stainless steel metal plate or aluminum diamond tread plate surfaces.
6. Conclusion
Whether you’re building a new metal clad house or upgrading an old facade, choosing the right material and installing it correctly makes all the difference. From corten steel siding cost considerations to selecting between pac clad hwp panels and standard corrugated steel facade systems, attention to detail ensures decades of performance. With proper care, your metal clad wall won’t just look stunning—it’ll stand strong against wind, rain, and time.
