1. Introduction
In the past 48 hours, architects and builders across North America have reported a surge in demand for sustainable, low-maintenance exteriors—especially metal clad wall systems. Driven by both aesthetic trends and climate resilience needs, homeowners are increasingly choosing materials like corten steel facade, zinc clad dormer, and colorbond standing seam for their metal clad house projects. If you’re considering this sleek, industrial look for your home or shed, you’ll need a clear, step-by-step plan to install and maintain it properly.
Metal clad doesn’t just refer to one product—it’s a broad category that includes everything from corrugated steel facade panels to aluminum clad sheet siding and even metal clad electrical wire for internal systems. Understanding the clad metal meaning and selecting the right metal clad type for your climate and design goals is the first critical step.
2. Choosing the Right Metal Clad Material
Not all metal siding is created equal. Your choice affects durability, cost, and maintenance. Popular options include:
- Corten steel siding: Rustic, self-protecting finish; ideal for modern homes but comes with a higher corten siding cost.
- Zinc metal siding: Naturally weather-resistant with a soft gray patina; often used in zinc facade or zinc clad roof applications.
- Copper siding: Develops a green patina over time; premium look but expensive.
- Exterior corrugated metal siding: Affordable and widely available; great for metal clad sheds or industrial-style homes.
- Vertical standing seam metal siding: Clean lines, excellent water shedding; often seen in pac clad standing seam roofs or pac clad column covers.
Also consider clad metals like aluminum clad steel or stainless clad aluminum for enhanced corrosion resistance. For budget-conscious projects, aluminum sheet for sale in 5052 or 6061 T6 grades offers a good balance of strength and workability.
3. Preparing for Installation
Before you hang a single panel, ensure your wall structure is ready. Metal clad walls need a solid, level substrate—typically plywood or OSB sheathing with a proper moisture barrier. Never install metal siding directly over bare studs.
Gather your tools: metal snips, drill with metal bits, tape measure, chalk line, and safety gear (gloves and eye protection). If you’re using pac clad hwp or pac clad coping, follow the manufacturer’s specs for fastener spacing and overlap.
Pro tip: Order 10% extra material to account for cutting errors or future repairs—especially important with specialty items like zinc clad dormer or corten steel plate.
4. Step-by-Step Installation Guide
Start at the bottom corner of your wall and work upward. Here’s how:
- Install a starter strip or base flashing to direct water away from the foundation.
- Attach furring strips (if required) to create an air gap behind the panels—this improves insulation and prevents moisture buildup.
- Begin with your first panel: align it with the chalk line, then secure it with corrosion-resistant screws designed for metal siding. Don’t overtighten—metal expands and contracts with temperature.
- Overlap panels according to the system type: corrugated sheets typically overlap by one full ridge, while standing seam systems use hidden clips (like snap clad clips).
- Cut panels to size using a circular saw with a metal-cutting blade or metal sheet cutting shears. Always cut away from your body.
- Finish edges with trim pieces—pac clad coping works well for roof-wall transitions, while aluminum clad stainless steel trim handles corners cleanly.
For electrical or plumbing penetrations, use metal clad electrical wire rated for outdoor use and seal all holes with high-quality silicone or butyl tape to maintain weather resistance.
5. Maintenance and Long-Term Care
One major advantage of a metal clad building is low upkeep—but it’s not zero. Here’s how to keep it looking great:
- Rinse your metal clad wall annually with a garden hose to remove dust, pollen, and salt (if near the coast).
- For stubborn stains on stainless steel plate or aluminum diamond tread plate, use mild soap and a soft brush—never abrasive pads.
- Inspect fasteners yearly; replace any that show signs of rust or loosening.
- Touch up scratches on painted systems (like colorbond) with matching touch-up paint to prevent corrosion.
Note: Corten steel siding shouldn’t be painted—it relies on its rust layer for protection. Similarly, zinc and copper develop protective patinas—cleaning them aggressively can damage this natural shield.
6. Common Mistakes to Avoid
- Skipping the moisture barrier: This can trap condensation and rot sheathing from behind.
- Using incompatible fasteners: Mixing metals (e.g., steel screws on aluminum) causes galvanic corrosion.
- Ignoring thermal expansion: Leave room for movement, especially with long runs of steel plate or aluminum clad sheet.
- Overlooking insulation: Metal clad insulation (like aluminum clad pipe insulation principles) can be added behind panels for better energy efficiency.
7. Conclusion
Installing a metal clad wall system—whether it’s a corrugated steel facade, zinc metal siding, or a full steel clad house—adds modern style and decades of durability. By choosing the right clad metals, preparing properly, and following best practices for installation and care, you’ll protect your investment and enjoy a striking exterior that stands the test of time. Whether you’re building a metal clad shed or upgrading your home with a corten steel facade, this guide gives you the foundation to succeed.
