Finishes and Coatings for Cladding Sheets

The right finish and coating can significantly enhance the durability and aesthetic appeal of metal cladding sheets. PVC plastisol coatings, for example, are recommended for buildings near the sea due to their higher resistance to salt air. This makes them an excellent choice for coastal structures, where corrosion from saltwater is a major concern.

Powder coating, which is another popular finish alongside polyester paint, can provide a guarantee of up to 25 years in normal environments. This makes it a durable choice for many applications. This type of coating not only provides a durable finish but also comes in a variety of colors, allowing for customization to match the building’s design.

Various types of finishes and coatings are available, each designed to enhance the longevity and visual appeal of metal cladding sheets.

Choosing the Right Thickness

It’s imperative to choose the right thickness for metal cladding sheets to guarantee optimal performance and structural integrity. Thinner sheets, such as those with a gauge of 0.5mm, are often more suitable for wall cladding applications. These sheets provide adequate protection without the need for enhanced structural support, making them a cost-effective option for exterior walls.

For roofing applications, thicker sheets are recommended due to their increased durability. Sheets with a gauge of 0.7mm are typically used for roofing, as they can withstand heavier loads and harsh weather conditions. The choice of thickness also affects the maximum length of the metal sheets, with 0.7mm sheets available up to 9 meters and 0.5mm sheets up to 7 meters.

Installation Techniques

Correct installation of metal cladding sheets guarantees a secure and weather-resistant finish. When positioning battens, it is important to ensure they are at least 50mm wide to easily fix sheets and spaced no further than 1.2m apart for 0.7mm thickness sheeting. This spacing helps in maintaining the structural integrity of the cladding.

Positioning each sheet so that it extends over the bottom purlin and eaves is essential for proper water drainage. This allows rainwater to drain into a gutter or beyond the wall, preventing water ingress. For end laps, a minimum sheet overlap of 250mm should be supported by a purlin beneath the lap. Using self-drilling TEK screws with a 5/16th hex-head and a stainless steel washer with a bonded neoprene pad ensures optimal performance and sealing.

When laying metal cladding sheets, follow these steps:

1. Start from the eaves and in the corner away from the direction of the prevailing wind.
2. Ensure the first few sheets are not fully fixed until correctly aligned to prevent side laps facing into the wind and water ingress.
3. These wall cladding sheets can be installed both vertically and horizontally, providing versatility in design.

Maintenance of Metal Cladding

Preserving the appearance and lifespan of metal cladding is straightforward. Here are some tips:

1. Regular cleaning is key to maintaining its appearance and prolonging its lifespan.
2. Use a soft bristle brush to clean the surface of metal cladding and remove dirt, cobwebs, and rain spots.
3. For stubborn dirt, only water should be used to avoid damaging the material and its coating.

For high-level cladding, the following steps are recommended for safety and effectiveness:

1. Use a ‘Reach and Wash’ system with purified water.
2. Regularly inspect the cladding to remove any debris, rust, and scratches during maintenance, preventing long-term damage.
3. Remove any excess material, known as swarth, to maintain the cladding’s integrity.

Overcoming Common Challenges

Tackling common challenges like thermal movement, wind loading, and corrosion is fundamental for the enduring performance of metal cladding systems. Movement joints must accommodate the combined effects of construction tolerances with thermal and moisture movements. This ensures that the cladding system remains intact despite temperature fluctuations and environmental conditions.

Wind loading is another significant challenge, especially for copings on parapet walls. These need careful design for load resistance and thermal movement. Securing the right attachment of fixings in heavy panels is necessary to avoid overloading fixings.

Additionally, understanding the interaction between cladding panels and supporting structures helps in avoiding misalignment and ensuring a robust installation.
