Metal cladding: a guide for exterior solutions
Types of Metal Panels
When it comes to exterior solutions, metal cladding stands out as a flexible and reliable choice. You’ll find a wide variety of materials and finishes, so it’s easy to match different architectural or construction needs. The main types of metal panels you’ll come across are:
Aluminum
Steel
Zinc
Galvanized steel
Each of these brings its own set of qualities, advantages, and best uses. It’s worth considering that the right type of metal panel often depends on your project’s climate, the kind of building, your budget, and, of course, the look you’re aiming for. Here in the U.S., metal cladding is a familiar sight on office buildings, schools, hospitals, industrial facilities, and more and more on residential homes, which just shows you how adaptable it really is.
Aluminum cladding
Aluminum cladding is especially popular in today’s construction scene, and for good reason. Its lightweight design, resistance to corrosion, and flexibility in design make it a top pick for both commercial and residential projects. If you’re looking for something that’s easy to install, looks great, and lasts, aluminum is hard to beat.
Key advantages include:
Wide range of shapes, sizes, and colors for custom designs
Non-combustible and meets important fire safety codes (including International Building Code - IBC)
Excellent weather resistance, meaning less maintenance over time
Particularly suitable for high humidity, rainy, or coastal environments
Completely recyclable, supporting sustainability and LEED Certification
Long-term warranties from U.S. manufacturers
Malleability for creative curves and geometric patterns
Steel cladding
Steel cladding is known for its strength and ability to handle impacts, which is why it’s often used for industrial buildings, warehouses, and any facility that needs tough protection from the environment. You’ll find steel panels in all kinds of profiles and finishes, including those coated or painted for better corrosion resistance.
Prone to rust if not properly coated or maintained
Modern powder coatings and metallic finishes improve longevity
Fluoropolymer-based paints or PVDF coatings help preserve color and surface quality
Fire-resistant and meets ASTM International standards
Ideal for large-scale projects (stadiums, transit centers) due to wind and impact resistance
Can be specified with insulation backing for better energy performance
Zinc cladding
If you want a look that stands out and actually gets better with age, zinc cladding is worth your attention. Zinc panels develop a natural patina over time, which not only looks unique but also helps heal minor scratches, keeping the surface looking consistent.
Durable, low maintenance, and highly resistant to corrosion
Patina acts as a self-healing shield
Works well with rainscreen systems for moisture management
Higher upfront cost, but long lifespan and low maintenance balance the investment
Commonly used in museums, libraries, and civic buildings for a distinctive look
Non-ferrous (won’t rust) and fully recyclable
Galvanized steel cladding
Galvanized steel cladding brings together the strength of steel and the protective power of zinc. The galvanization process—usually done by hot-dipping—coats the steel with zinc, giving it solid resistance to corrosion.
Practical for environments with moisture, chemicals, or pollutants (agricultural, industrial, commercial)
Meets a range of ASTM International standards
Affordable, easy to install, and compatible with other building systems
Develops a weathered look over time, which many find visually appealing
Modern panels can have extra factory-applied coatings for added durability
Benefits of Metal and Aluminum Cladding
There are plenty of reasons why metal cladding is a smart choice for exteriors in the U.S.:
Durability: Handles impacts, weather, and fire for long-term protection. Especially valuable in areas with severe weather (hurricanes, hailstorms), as highlighted by FEMA and the American Institute of Architects.
Design Flexibility: Customizable for complex curves, textures, and a wide range of colors and finishes. Great for businesses and schools wanting unique exteriors.
Energy Efficiency: Supports insulation and rainscreen technologies, improving thermal performance and helping meet energy codes and LEED Certification. Reduces thermal bridging and supports continuous insulation.
Low Maintenance: Aluminum and zinc require minimal cleaning and resist mold, mildew, and pests, reducing operating costs.
Sustainability: Recyclable at the end of their useful life, supporting sustainability and landfill reduction. Some cities and states offer incentives for using recyclable materials.
Aluminum Cladding Systems
aPlank is a trusted name when it comes to aluminum cladding systems in the U.S. Their solutions are designed to meet both the technical and visual demands of modern construction. The aPlank system uses extruded aluminum panels that are engineered for a precise fit, easy installation, and long-term durability.
Built to meet U.S. building codes, including fire safety and wind load requirements (IBC)
Wide range of finishes and colors for creative flexibility
Compatible with rainscreen installation methods for moisture management and enhanced building envelope performance
Used on major office towers, schools, and healthcare facilities nationwide
If you’re researching metal cladding, aPlank offers resources and technical documents to help you make informed decisions at every stage of your project. They provide detailed guides, CAD drawings, and compliance certificates so you can confidently integrate aPlank into your plans.
Use of Sustainable Products in Aluminum Cladding
Sustainability is more important than ever in U.S. construction, and aluminum cladding systems can play a big role in helping projects meet green goals.
Many aluminum panels are made with a high percentage of recycled content (up to 90% for some U.S. manufacturers)
Fully recyclable at the end of service life, supporting a circular economy and reducing landfill waste
Manufacturers often aim for LEED Certification and other green standards (WELL Building Standard, Green Globes)
Advanced coatings reduce energy absorption, helping lower the heat island effect and improve energy efficiency
Reflective finishes and cool roof coatings can lower air conditioning costs in cities like Los Angeles or Houston
High-reflectance materials may be required by local codes, making sustainable aluminum cladding a smart compliance choice
Key Considerations for Achieving an Optimal Aluminum Panel Design and Performance
When designing and choosing an aluminum cladding system, keep these factors in mind:
Ensure materials meet ASTM International standards for quality and follow the International Building Code (IBC) for safety and performance
Integrate rainscreen systems properly to manage moisture, prevent water intrusion, and allow ventilation behind panels
Consider panel thickness, attachment methods, and finishes based on your location (coastal, industrial, high-wind areas may require extra protection)
Pay close attention to installation details—using the right fasteners, sealing joints properly, and aligning panels correctly is critical
Work with experienced professionals and follow manufacturer guidelines; consider third-party inspections for large or complex projects
Plan for maintenance: regular cleaning, checking joints and fasteners, and touching up damaged finishes will help maximize your investment and keep your building looking its best
