Plastic Manhole Covers & Frames

Plastic manhole covers offer a combination of different benefits over alternate covers made from galvanised steel or ductile iron, including corrosion resistance, easy installation and handling, thanks to being lightweight, and durability for use in residential and light commercial settings. They are anti-slip and can be installed in more hazardous environments thanks to the non-conductive properties.

Plastic manhole covers made from polypropylene or PVCu are ideal for use in pedestrian walkways, driveways and other light-traffic areas. They are commonly installed in residential properties, parks, sports facilities and schools. While not suitable for heavy industrial loads, the highest load-bearing capability being up to 5 tonnes means they are suitable for inspection chambers and utility access points, where strength, weather resistance and low maintenance are essential.

All plastic drain covers supplied by Drainfast are given a FACTA rating, which indicates the maximum load, or weight, they can withstand. Our polypropylene manhole cover load ratings range from FACTA A – for pedestrian use and up to 5kN wheel loads – to FACTA B – appropriate for cars and vans up to 50kN wheel loads. To discuss your project’s load-bearing requirements, speak to our team and we’ll find the most suitable manhole covers.

Plastic drain and manhole covers are designed to be highly weather resistant against various conditions, including rain, UV exposure, frost and heat. The plastic materials are corrosion resistant, meaning the covers won’t rust, warp or degrade over time. This makes them an excellent choice for long-term outdoor use, especially in areas with fluctuating climates or exposure to moisture and chemicals.

Thanks to being very lightweight compared to metal covers, plastic drain covers are very easy to install and handle. They won’t require specialist lifting equipment, and their user-friendly design allows for quick placement and replacement using lifting keys, reducing installation time and labour costs.

When properly installed and used within their intended load class, plastic drain covers from Drainfast can last over 20 years. They are highly durable, weather resistant and require minimal maintenance. Unlike metal alternatives, they won’t rust or become brittle, making them a cost-effective and long-lasting solution.
