You may wonder exactly how your Roofing Sheets are made? Do they arrive profiled? How are they cut to length? How is the colour applied? We aim to answer all these questions and more in this blog.


Your Cladco Roofing Sheets start their life as a steel coil. These are brought into us from a variety of suppliers, mostly Tata Steel.

The steel in these coils is pre-galvanised to provide it with adequate protection from the elements, as well as being rust-resistance for a long-lasting roof.


The galvanised steel coils come to us with the required coatings: Polyester Paint, PVC Plastisol or Prelaq Mica. They are provided in a variety of colours and thickness, including 0.5mm, 0.6mm or 0.7mm, ready to be formed into profiled Roofing Sheets.

Our Roofing Sheets are available in five colours for Polyester Paint, 11 colours for PVC Plastisol, and three colours for Tile Form Sheeting.

Both Box Profile and Corrugated Profiles are also available to order with no colour applied in a plain galvanised finish.


Coils are extremely heavy, with each coil weighing approximately 3.5-5 tonne. This means they have to be carefully moved using a forklift or gantry crane.

As you can imagine having all these different colours, finishes and sizes available requires a vast amount of steel coils to be stored on the premises.

The coils are then moved using a gantry crane onto the decoiler ready to be fed into the roll forming machine.



At this stage, Dripstop anti-condensation membrane can be added to the reverse side of the sheet, if selected by the customer at the time of ordering.

The grey polyester fleece within Dripstop prevents condensation from dripping off, with specially designed pockets that trap water droplets.



The steel coil is fed through the roll forming machine and the first stage creates the centre profile of the Sheet.


The steel Sheeting then follows the line to create a second profile, and so on until the Sheet has become the finished profiled product. This process maintains the structural integrity of the Sheet as it is being formed.

The Sheet is then fed through a guillotine to the required length and cut to size. We can cut our Roofing Sheets to specific lengths depending on your project.


You can find the maximum lengths that we are able to cut each profiled sheet to on the relevant product pages for CorrugatedBox Profile and Tile Form.

Each Sheet is then stacked on top of one another in a neat pile to create the finished order. We then add a cover sheet to the top of the order to prevent any damage or scuffs to the finish.

So there you have it! The before and after of a profiled metal Sheet is broken down into simple stages.

Roofing Sheets vary in pricing according to the size, profile and finish. For more information on our Roofing Sheets, please visit our FAQ section, or contact our Sales team on 01837 659901 to find out more.
