1. Introduction
In the past 48 hours, architects and builders across North America have seen a surge in demand for sustainable, low-maintenance exteriors—driven by rising wildfire risks and energy efficiency mandates. Metal clad solutions like corten steel siding and zinc clad roofs are topping the list, thanks to their fire resistance, longevity, and modern aesthetic. If you’re considering upgrading your home with metal cladding, this guide will show you exactly how to install and maintain it properly.
Metal clad isn’t just a buzzword—it’s a versatile category that includes everything from corrugated steel facades to aluminum-clad stainless steel panels. Whether you’re building a new metal clad house or retrofitting an old one, getting the details right matters.
2. Understanding Metal Clad: What It Really Means
Before diving into installation, let’s clarify what ‘metal clad‘ actually means. The term ‘clad metal meaning’ refers to a composite material where one metal is bonded to another—like aluminum clad steel or copper nickel clad—for enhanced corrosion resistance, strength, or appearance. In construction, ‘metal clad’ often describes exterior systems such as metal clad wall panels, metal clad roofing, or even metal clad electrical wire used behind the scenes.
- Common types include: corten steel facade, zinc metal siding, copper siding, and vertical standing seam metal siding.
- Popular branded systems: Colorbond standing seam, PAC Clad HWP, and PAC Clad column covers.
3. Choosing the Right Metal Clad Siding for Your Project
Not all metal siding performs the same. Your climate, budget, and design goals should dictate your choice.
For rustic-industrial looks, corten steel siding is ideal—but be aware of corten siding cost, which can run $8–$15 per sq. ft. installed. Zinc clad dormers and zinc clad roofs offer self-healing patinas and last 80+ years. Aluminum clad sheet or aluminum diamond tread plate works well in coastal areas due to salt resistance. And for sleek modern homes, a standing seam facade in stainless steel plate or 6061 T6 aluminum plate delivers clean lines and durability.
Pro tip: If you’re comparing steel plate price vs. aluminum sheet for sale, factor in lifecycle costs—not just upfront expenses.
4. Step-by-Step Installation Guide
4.1. Prepare the Substrate
Ensure your wall framing is level and sheathed with a weather-resistant barrier (WRB). Use furring strips if needed to create an air gap—critical for moisture management behind metal clad wall systems.
4.2. Measure and Cut Panels
Use metal sheet cutting tools like aviation snips or a circular saw with a metal-cutting blade. For precision, mark cuts on aluminum clad steel or stainless steel 316 sheet using a straight edge. Always wear safety gear—metal edges are sharp!
4.3. Install Starter Strips and Flashing
Begin at the bottom. Attach corrosion-resistant starter strips and integrate PAC Clad coping or drip edges at transitions (e.g., roof-to-wall). This prevents water intrusion—a common failure point in metal clad buildings.
4.4. Attach the Cladding
For vertical standing seam metal siding, use hidden fasteners to avoid thermal bridging. With exterior corrugated metal siding, screw through the crest of the wave into structural framing. Maintain manufacturer-recommended expansion gaps—especially with materials like 7075 aluminum plate that expand significantly with temperature changes.
4.5. Seal Joints and Penetrations
Use compatible sealants at seams, windows, and utility penetrations. Never caulk tightly—allow movement. For electrical runs, metal clad electrical wire (like aluminum clad steel wire or CU clad wire) must be properly grounded and protected when passing through walls.
5. Common Problems and How to Avoid Them
One frequent issue is oil-canning—visible waviness in large flat panels. Prevent it by using stiffened panels or choosing textured finishes like diamond plate steel sheets.
Another pitfall: galvanic corrosion. Never directly join dissimilar metals (e.g., aluminum clad stainless steel next to untreated mild steel plate). Use isolation tapes or non-conductive spacers.
Also, avoid walking on thin-gauge metal during installation—it can dent or deform. Use walk pads or distribute weight evenly.
6. Maintenance Tips for Longevity
Metal clad siding is low-maintenance but not zero-maintenance. Rinse annually with water to remove debris and pollutants. For zinc or copper siding, never use acidic cleaners—they disrupt the protective patina.
Inspect fasteners yearly; replace any that show rust (especially on boiler plate steel or carbon steel plate components). Touch up scratches on color-coated systems like Colorbond to prevent underfilm corrosion.
If you live near the coast, consider electroless nickel or chromium electroplating on exposed hardware to boost salt resistance.
7. Conclusion
Installing metal clad siding correctly transforms your home into a resilient, stylish, and future-proof structure. From choosing between a corten steel plate accent wall and a full zinc facade to properly routing aluminum clad pipe insulation or metal clad wire, attention to detail ensures decades of performance. Whether you’re building a steel clad house or upgrading a metal clad shed, this guide gives you the foundation to do it right—the first time.
