Corrugated Roofing Sheets

Corrugated Roofing Sheets by Cladco are one of the more traditional Profiles from our range of Metal Roofing Sheets. Made from high-quality Galvanised Steel, they feature 13 round corrugations across their width - which improves their structural integrity and provides an authentic waved appearance.

13/3 Corrugated Profile Sheets have been popular among agricultural building projects and barns for many years thanks to their long-lasting, durable structure. Now, they are seeing an increase in popularity when used as a Metal Wall Cladding material on more contemporary domestic and commercial building project styles, especially in a black finish.

Cladco 13/3 Corrugated Roofing Sheets are a cost-effective roofing option, with their lightweight yet robust profile making them quick and easy to install.

Sheets are produced in both 0.7mm and 0.5mm thicknesses depending on their end use. If being used for cladding buildings, we recommend 0.5mm thick Sheets as they do not need to support any load-bearing weight as a Roof Sheet would.

Corrugated Roof Sheets are available in plain Galvanised finishes as well as a range of Colours and Coatings to suit your project requirements. These include:

  • PVC Plastisol; a 200-micron thick coating of high-quality PVC Plastisol, with an embossed leather grain finish. This Coating is available in a range of 11 colours.

  • Polyester Paint; a 25-micron thick, smooth enamel coating. This Coating is available in five colours.

Advantages of Corrugated Sheets

Cladco 13/3 Corrugated Roof Sheets are a durable and long-lasting Metal Roofing option. Sheets are custom-made to order in our Okehampton-based warehouse.

The 13 round corrugations along the width of each Sheet provide additional strength to the already robust steel material, whilst the waved profile provides excellent rainwater run-off and prevents any leaves and debris from building up on your Roof in poor weather conditions.

When used in Roofing applications, construction can be safely undertaken down to a pitch of 10 degrees using Self-Drilling Screws.

For additional strength, a range of Coatings including PVC Plastisol and Polyester Paint can be applied to the Sheets during the manufacturing process, to improve longevity, durability, and add aesthetic appeal.

Corrugated Sheets can also be used as Metal Side Cladding Sheets and offer a modern alternative to traditional wall cladding materials, such as timber or bitumen tiles, making for a cost-effective cladding solution due to their excellent longevity (when PVC Coating is applied) and low-maintenance properties.

Cladco Corrugated Metal Roofing Sheets give a 990mm Sheet coverage when lapped, giving more scope compared with other roofing brands on the market - with their lightweight profile making for a quick and easy installation with minimal tools. Install Corrugated Roofing Sheets for your next DIY project to create a stylish versatile roof to suit your building.

PVC Plastisol

PVC Plastisol coated sheeting is manufactured from a pre-finished steel sheet with a 200-micron thick coating of high-quality, PVC Plastisol, featuring an embossed leather grain finish.

This Coating improves the longevity of the Sheet and adds a lifespan of approximately 15-25 years to the first maintenance or repaint, with a life in excess of 40 years in normal environments. PVC Plastisol also improves the Sheet's resistance to scratching and external damage.

PVC Plastisol produces a Roofing Sheet with excellent corrosion resistance and climatic protection, together with abrasion resistance and high strength. We provide an extensive variety of eleven colours, where choice and aesthetic appeal can be matched to environmental and performance requirements. These colours include: Anthracite, Black, Chestnut, Goosewing Grey, Slate Blue, Vandyke Brown, Merlin Grey, Juniper Green, Moorland Green, Olive Green, and White.

PVC Plastisol colour choices

Polyester Paint

Polyester Paint Coated Sheeting is manufactured from a 25-micron thick, smooth enamel-coated Steel Sheet, which is economical to use and gives excellent weather resistance. This Coating has longevity of typically 8 to 12 years to the first maintenance or repaint, with a life in excess of 20 years in normal environments.

We provide a variety of five colours in our Polyester Paint Coating, where choice and aesthetic appeal can be matched to environmental and performance requirements. These colours include: Slate Blue, Juniper Green, White, Black and Light Grey.

Galvanised

The coated steel strip we form into Roofing Sheet Profiles and Flashings is produced by leading suppliers, giving us control over the quality and traceability of the material we use. To produce high-quality, pre-coated Sheeting, a system of multi-layered Coatings is applied to a zinc-coated, high-tensile steel strip and oven-cured to ensure optimum adhesion.

How Many Sheets Do I Need?

We don’t want to leave you guessing on how many Sheets you will need to order, especially if you are encountering your first Roofing project using 13/3 Corrugated Roofing Sheets. Providing a 990mm width coverage once installed, it's important to order the right number of Sheets for your project.

Our handy Roofing Sheet Calculator will guide you through how many Sheets to order, as well as what potential Flashings and Accessories you may need. Our Calculator will also provide you with the total cost of your upcoming project.

Installing Your Corrugated Roofing Sheets

Providing you with great products you can work with is one thing but having the right guidance and know-how to complete the job relies on the best help and advice.

For a single-pitch roof, the minimum pitch we recommend is 10 degrees. Laying Metal Sheets in runs is normally the ideal way to achieve the best start to your Roofing project. We recommend starting at the eaves and in the corner away from the direction of the prevailing wind (if it’s a single-Sheet run).

For more information and further installation help and advice, take a look at our Corrugated Sheet Installation Guide or our Roof Help and Advice page.

Additional Materials

Roof Flashings are used to finish the ends and corners of a run of Corrugated Roof Sheets, helping to protect your building against water intrusion as well as being an integral component of your Corrugated Roof. Flashings are also a good way to enhance the aesthetics of your project.

Additionally, we stock a selection of Roofing Accessories and Purlins that complement and support your Roof, helping to achieve a professional and durable finish. Accessories include Screws, Screw Caps, Foam Fillers and more.

Frequently Asked Questions

What are the benefits of a Corrugated Roof?

Corrugated Metal Roofing Sheets are available in up to 12 colours with three coatings, and are suitable for use on almost any agricultural, industrial and commercial project. They can be cut to custom lengths and provide a wider-than-average cover of 990mm when lapped.

What Coating is best for my Corrugated Sheets?

If you are looking for the longest possible lifespan for your Roofing Sheets, we would recommend using PVC Plastisol Coating. For colour variation and aesthetic appeal with a longer lifespan than Plain Galvanised, we would recommend using our Polyester Paint Coating.

For more information on all our Roofing Sheet Coatings, take a look at our advice page.

What thickness of Corrugated Sheet is best for my project?

If used as a Side Cladding material, we recommend using a 0.5mm thickness for your Sheets, as cladding does not need to carry any load-bearing weight as a Roof Sheet would. For Roofing applications, we would recommend using either thickness depending on the surrounding weather conditions - for example, areas with high side winds will require a thicker Sheet.

What is the width of your Corrugated Sheets?

The standard width of our Sheets is 990mm when lapped.

What lengths of Corrugated Sheets do you do?

Our Sheets are available in any custom-cut length up to 7 metres for 0.7mm thicknesses and 5 metres for 0.5mm thicknesses.

How much do you overlap Corrugated Sheets?

During installation, we recommend fitting your Corrugated Roofing Sheets with an overlap of at least two corrugations.

What degree of pitch can I use Corrugated Roofing Sheets with?

The minimum degree of pitch we would recommend is 10.
