While a variety of materials are used to create cladding, metal cladding is the top option for many homeowners and business owners due to its form, functions, and advantages.

But what is metal cladding, and what should you know about it? This article discusses the fundamentals. Read on!

What is Metal Cladding?

Metal cladding is a product made of layered metal. It performs the same function as other cladding options — protecting the exterior walls (or the interior) of a building. Metal cladding may also be used for roofing material.

Aside from structural protection, the metal cladding also has aesthetic and design purposes, adding versatility to any structure.

Types of Metal Cladding

Compared to other types, — such as stone, concrete, and wood — metal cladding strikes an optimal balance between function and aesthetic. Various metals can be made into cladding, offering versatility and other mechanical properties:

Aluminum

Some projects opt for aluminum cladding, as aluminum offers more resistance against rust and corrosion. It is often used for homes, commercial centers, and other buildings in humid climates.

Aluminum cladding offers other benefits, such as being lightweight and highly versatile when it comes to coating and painting. However, it is not as strong as other metals, so it may not be applicable in harsher environments.

Steel

Steel cladding’s most important advantage is its high strength. When it comes to rust resistance, steel may not be the best option — but certain grades of steel offer good protection.

As it is extremely durable, it is popular for exterior and interior cladding. This type is best applied in buildings where long-lasting strength is required, such as in industrial settings.

Copper

Copper cladding offers adequate protection against the elements but oxidizes quickly — turning from shiny orange to light green — unless a protective coating is applied. Thus, it is often chosen for its aesthetic appeal rather than any protective advantage it may offer. It is typically used for roofing and other finishing work.

Beneficial Properties

All metal cladding systems offer more or less the same properties:

Protection and Strength

Metal cladding can protect and shield a structure from ever-changing and harsh elements that may damage it — such as rain, winds, pollution, and temperatures. They’re strong and durable enough that they improve the stability and lifespan of a structure. Often, metal cladding products are long-lasting and manufacturers sell them with warranties as long as 30 years or more.

Weight

Metal cladding can be quite lightweight, reducing the load of the building, and also making this material much easier to transport, install, and repair.

Non-Combustible

All metal building materials must be resistant to fire. This puts metal cladding above other materials — such as wood panels — in terms of protective advantages.

Aesthetics

Metal cladding is often used for architectural and design purposes. While there are many practical benefits to using this product, it offers many aesthetic benefits as well. Installing cladding can change the overall look of a building. Both material and installation choices may be used in such a way that it creates varying styles.

Environmentally-Friendly

As it is made from common materials, metal cladding can easily be recycled at the end of its life. As a result, you can reduce your building’s carbon footprint.

Installation Options

There are two main ways to install metal cladding:

  • Single-skin — The cladding alone is applied to the building, and acts as the protective barrier to external elements.
  • Double-skin — Insulation is installed in between two layers of metal cladding, improving ventilation and energy efficiency.

Aside from that, there are many different ways to configure metal cladding. Configuration is important as it affects the overall look of the building.

Common setups include panel, strip, brickwork, mesh, cassette, textile, tube, shingle. Some configurations offer better thermal insulation, protection, and durability.

Finish Options

Aside from configuration, there are multiple finishes to choose from that will affect the aesthetics of your building. The most popular options are: polished, smooth, natural, textured, ribbed, perforated, matte, oxidized, and lacquered. The best choice for your building will depend largely on your personal preference and budget.

Other kinds of finishes a manufacturer may offer are: grooved, patina, painted, high-gloss, brushed, sandblasted, 3D-printed, aged, oiled, brush-hammered, metalized, lozenge-patterned, and mirror.

Additional Characteristics

There are options for metal manufacturers to add additional characteristics to metal cladding projects. Aside from offering non-combustible, sturdy, and weather-resistant protection, your metal cladding may have other characteristics.

Common additions include LED lighting, backlighting, and planters (to grow plants like moss, ferns, vines, etc.). These additional characteristics improve the aesthetic appeal and help create better-looking facades and environments.

Maintenance Needs

Depending on the material, configuration, finish, and additional characteristics you choose for your building, your metal cladding will have different maintenance needs.

Here are a few pointers for taking care of metal cladding to extend its lifespan:

  • Remove dirt and stains — Using metal cleaning products, remove any traces of dirt from your cladding to prevent rust or pollutant build-up.
  • Apply to coat or paint — When the surface is completely clean, apply a new coat of protective paint to keep your metal cladding looking good as new. You may also treat it with weather protection coatings, such as sealant or glue, to keep it intact in harsh weather conditions.
  • Replace broken pieces immediately — When you spot damage, have the cladding replaced immediately.

Key Takeaway

Now that you know what metal cladding is and the structural and aesthetic benefits it offers, you may be interested in learning more about this product and how it may be applied to your construction project.

Introduction to Clad Metals: Uniting Diverse Properties for Advanced ...

In the ever-evolving landscape of material science, clad metals stand out as a revolutionary innovation that combines the best attributes of different metals and alloys. This article is the introduction to a series about clad metals that will discuss how what they are, how they’re made, their benefits, and their applications.

By employing advanced metallurgical bonding techniques such as plating, welding, roll bonding, and heat treatment, clad metals bring together materials with contrasting properties to create a unified product with a completely new set of capabilities. This unique amalgamation allows for the development of materials that can meet the stringent demands of modern engineering and industrial applications.

Clad metals are engineered to harness the strengths of their constituent materials, resulting in combinations that were previously thought to be incompatible. For instance, imagine a material that offers both high electrical conductivity and high strength, or one that combines high thermal conductivity with exceptional stiffness. These seemingly conflicting properties can be unified into a single material which enables a completely new set of properties (see also Figure 1).

The versatility of clad metals opens a plethora of possibilities across various industries. Here are some compelling examples of the unique property combinations that clad metals can achieve:

  • High Electrical Conductivity + High Strength: Ideal for applications in the electronics and power transmission sectors, where materials need to conduct electricity efficiently while maintaining structural integrity.
  • High Electrical Conductivity + High Wear Resistance: Perfect for components that require both excellent electrical performance and durability, such as connectors and switches.
  • High Thermal Conductivity + High Stiffness: Essential for heat exchangers and thermal management systems, where efficient heat transfer and mechanical stability are crucial.
  • High Corrosion Resistance + High Strength: Suitable for harsh environments, such as marine and chemical processing industries, where materials must withstand corrosive elements while maintaining strength.
  • High Strength + High Formability: Beneficial for manufacturing processes that require materials to be both strong and easily shaped, such as automotive and aerospace components.
  • High Conductivity + Good Surface Wettability: Important for applications in electronics and coatings, where materials need to conduct electricity and interact well with other surfaces.

Two aspects are particularly important for clad metals: the selection of the material components and the process of metallurgical bonding (electroplating, laser or electron beam welding or roll bonding). The material components are chosen based on which properties are needed in the final material.

Several aspects are relevant when choosing the appropriate cladding method:

  • The clad material combination
  • The metal clad geometry (material arrangement, layer thicknesses)
  • The effect of the cladding method on bulk and interface properties

Some of these aspects are summarized in Table 1.
