Corrugated Roofing Sheets

Advantages of Corrugated Sheets

Typical Uses

Cladco Corrugated Roof Sheets are a traditional yet highly versatile roofing and side cladding solution and suited to a wide variety of building types, including:

13/3 Profile

Coatings

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.

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.

The reverse/internal surface of the Polyester Box Profile Roofing Sheets is coated with a standard alkali grey wash coat.

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.

Dripstop Anti-Condensation Option

Cladco Corrugated Roofing Sheets are also available with Dripstop Condensation Control - a proven solution to preventing drips from forming on the underside of your Roofing Sheets, especially in conditions of high humidity.

What is Dripstop? Dripstop is an anti-condensation adhesive felt membrane that is applied to all our Roofing Sheets during the manufacturing process.

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.

Supporting 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.

Corrugated Roof Lights

Their width and profile match that of our 13/3 Corrugated Metal Roof Sheets, ensuring these translucent Roof Light Panels can be installed seamlessly together with the 13/3 Corrugated Roof Sheets. GRP Translucent Roof Lights are available in lengths of 2.5m, 3m and 3.5m.
