Coloured corrugated plastic sheets are a versatile, durable, and affordable option for roofing, cladding, skylights, partitions, and signage. The sheets are made from materials such as polypropylene, PVC, or polycarbonate, and their corrugated structure refers to the wave-like pattern that runs along the surface, providing additional strength without adding significant weight. During the manufacturing process, pigments are added to the melted plastic to create a variety of colours, from vibrant shades to more subtle tones. These sheets are ideal for outdoor projects as they can withstand external stresses such as wind, rain, and hail, while also being resistant to fading from UV rays.

What You'll Learn
Choosing the right product
Coloured corrugated plastic sheets are made from durable plastic materials such as polypropylene, PVC, or polycarbonate. The "corrugated" structure refers to the wave-like pattern on the surface of the sheet, providing additional strength without adding significant weight. This makes them ideal for roofing applications as they can withstand external stresses such as wind, rain, and hail.
When choosing coloured corrugated plastic sheets, it is important to consider the purpose and specific requirements of your project. These sheets are available in a wide range of colours, from vibrant shades to more subtle tones, ensuring there is an option to match any design or aesthetic need. For example, if you require maximum light transmission for a skylight or greenhouse project while maintaining weather resistance, transparent or clear corrugated plastic sheets are a suitable option.
The addition of pigments during the manufacturing process not only provides colour but also enhances the durability of the sheets by making them resistant to fading from UV rays, ensuring their colours remain vibrant over time. Therefore, when choosing a product, consider the level of UV protection you require to preserve the colour and integrity of the sheets.
Additionally, depending on your project's specific needs, you may opt for a particular thickness. For instance, thicker sheets may be preferred for roofing applications to withstand harsh weather conditions and provide greater insulation. In contrast, thinner sheets could be suitable for signage or decorative purposes, offering flexibility and ease of installation.
Finally, consider the availability and cost of the coloured corrugated plastic sheets. These sheets are known for their affordability and can often be found at hardware stores or purchased online. Comparing prices and sourcing the sheets from a reputable supplier will ensure you receive a quality product that meets your expectations and budget.

Installation tips
Coloured corrugated plastic sheets are a versatile, durable, and affordable option for roofing, cladding, skylights, partitions, and signage. The sheets are made from materials such as polypropylene, PVC, or polycarbonate, with a wave-like pattern that adds strength without significant weight increase. This structure makes them ideal for external use as they can withstand wind, rain, and hail. The addition of pigments during manufacturing also makes them resistant to UV-induced fading.
- Before starting, ensure you have all the required materials, including the sheets, flashings, eaves fillers, and fixings. Tools like a circular saw, angle grinder, or fine-toothed saw may be needed for cutting sheets, and a drill is necessary for pre-drilling holes.
- Measure and mark the roof: Place the sheets on the roof, allowing for a 60mm overhang for rainwater runoff and ensuring they are wide enough to reach the barge board. Mark the areas where holes will be drilled and cuts will be made. Individual sheets should overlap by at least one corrugation, and placement should be from left to right.
- Cut the sheets: If cutting is required, use the appropriate tool and follow safety guidelines. For a fine-toothed saw, cut at a shallow angle with light pressure for cleaner cuts. Sandwiching the sheet between two other sheets with the excess part protruding can make cutting easier.
- Pre-drill holes: After making the necessary cuts, drill holes in the marked areas. The holes should be slightly larger than the fixings to accommodate potential expansion. Drill each hole individually with a masonry bit, applying light pressure and using a low drill speed. Support the sheet under each hole position, and use at least five fixings across the width of each sheet.
- Prepare the roof: Install wall flashing at the top of the slope and secure it firmly. Insert foam eaves fillers underneath the sheets at all support positions to prevent roof chatter and provide additional support during sheet fixation.
- Secure the sheets: Attach the sheets to the roof using the pre-drilled holes and fixings. Ensure that the fixing screws are tight and place caps on the screws. If joining sheets end-to-end, create an overlap of at least 150mm for a 5-degree slope and 300mm for a 10-degree slope.
- Consider roof slope: The minimum slope for a roof with corrugated plastic sheets is typically 1-1/2" for every 12". Adjust the installation accordingly, especially when joining sheets end-to-end.
- Purlins and alignment: The top purlins should be about two inches down from the ridge, allowing space for the plastic to expand in warmer temperatures. Ensure the purlins are installed correctly and are parallel to the eaves, or the sheets may not fit properly.
- Storage and handling: Plastic sheets should be transported and stored horizontally on sturdy pallets that are equal to or larger than the sheets. Secure the sheets to the pallet during transportation and handling to prevent scratches or damage.
- Profile matching: When using corrugated plastic sheets in conjunction with metal roofing sheets, ensure the plastic corrugation profile matches the metal profile. Slight differences in corrugation depth or height can lead to insufficient sealing and water leakage.

Maintenance tips
Coloured corrugated plastic sheets are a highly popular choice for roofing, siding, and cladding applications due to their durability, affordability, and versatility. The unique corrugated structure provides additional strength without adding weight, making these sheets ideal for withstanding external stresses like wind, rain, and hail.
- Regular Cleaning: Coloured corrugated plastic sheets are easy to clean and maintain. It is recommended to clean the sheets periodically to remove any dirt, debris, or grime buildup. This can be done by gently washing the sheets with a mild detergent and water solution, using a soft cloth or sponge. Ensure complete drying after washing to avoid water stains.
- Protection from Scratches: Take precautions to avoid scratching the surface of the coloured corrugated plastic sheets. Avoid using abrasive cleaning tools or harsh chemicals as they can damage the smooth surface and affect the sheet's colour and overall appearance.
- UV Protection: The coloured corrugated plastic sheets are designed with pigments added during the manufacturing process, making them resistant to fading from UV rays. However, it is advisable to minimize direct and prolonged exposure to intense sunlight to maintain the sheet's colour vibrancy. Consider providing shade or covering for the sheets, especially in regions with intense sunlight.
- Weather Protection: While the coloured corrugated plastic sheets are durable and weather-resistant, it is essential to take additional measures in extreme weather conditions. In areas with heavy snowfall, ensure that snow does not accumulate on the sheets, as the weight can cause structural stress. Similarly, in regions with high winds, ensure the sheets are securely fastened to withstand strong gusts.
- Maintenance of Surrounding Areas: Maintain the surrounding areas of the coloured corrugated plastic sheets to prevent any potential damage. Keep trees and branches trimmed, especially if they are in close proximity to the sheets, to avoid any scratching or puncturing of the surface. Ensure that gutters and drainage systems are clear of debris to prevent water buildup, which could lead to moisture-related issues with the sheets.
By following these maintenance tips, you can ensure that your coloured corrugated plastic sheets retain their structural integrity, aesthetic appeal, and vibrant colours for years to come.
