Cladding Coatings Explained

Cladding Coatings are used to protect against corrosion or improve insulation in buildings, and can be applied in a wide range of colours and finishes to create a unique design and aesthetic for any building. They are low maintenance, with a simple wash being sufficient to keep them looking clean and new. This also reduces the risk of bacteria build-up and mould, which is ideal for hospitals, offices, and other commercial buildings.

While coating and cladding are both effective solutions for protecting metal surfaces from corrosion, the context in which they’re employed can have a big impact on their effectiveness and suitability. For example, while cladding provides better protection against corrosion than coating, it’s not suitable in situations where the metal is exposed to high temperatures. In these circumstances, a coating might be a better choice, as it can be applied in more resistant materials such as ceramics.

Cladding can be made from a number of different materials, including steel and PVC. These are often preferred by builders due to their durability, energy efficiency, and aesthetic appeal. They are also watertight and provide a seal that prevents moisture intrusion, reducing the risk of damp, mold, and fungus growth.

Choosing the right material is crucial for both functionality and aesthetics, as the surface of the cladding will be visible in most cases. This is why both cladding and coating are available in a wide range of colours, textures, and designs to allow the user to choose the best option for their project. For projects involving metal surfaces that will be exposed to harsh environments, ceramic or refractory cladding is typically chosen. These materials are designed to withstand high temperatures and are resistant to chemical damage.

Laser cladding is a process that uses a laser to melt and deposit metal onto substrates, creating protective or functional coatings. The process differs from other cladding methods in that it leaves fewer heat-affected zones, requires less material waste, and can be used to create intricate geometries. Additionally, laser cladding is compatible with a wide variety of materials.

There are two main types of laser cladding: wire-fed and powder-fed. Wire-fed laser cladding involves melting and depositing metal from a metal wire, while powder-fed laser cladding uses lasers to melt and deposit metal from a powder. The latter is also known as direct energy deposition (DED).

Cladding can be applied to machine parts in order to repair damage, enhance performance, or to increase the lifespan of the part. Cladding is particularly useful for machines that operate under high temperature and pressure, as it helps to mitigate wear and corrosion. Cladding can also be applied to reduce heat loss, which is an important factor when it comes to reducing energy costs.
