Highway manhole covers

Our range of Highway ironwork is designed to be sturdy, dependable, and easy to use. Available in two load classifications, D400 and E600. We take pride in creating a road manhole cover that's durable yet simple to operate and install. Highway offers high-quality products within a clear range that makes product selection easy. The Highway range is the largest ironwork range of sizes and depths available in the UK, making it easy to specify and install. With thoughtfully designed features and high-quality engineering to exceed the most stringent standards and guidelines set by national highway authorities, you can rest assured that you are getting the best product available.

> 1,500 Annual Average Daily Traffic (AADT)?

With the introduction of CD 534 there were several key changes. This includes the requirement for E600 manhole covers to be installed in place of D400 covers where the Annual Average Daily Traffic (AADT) of light goods vehicles travelled on a road is greater than 1,500 in each direction.

As a "rule of thumb", most A roads will have an annual average daily traffic number over 1,500 light goods vehicles. Full traffic data can be found for many locations around the UK on the Government website.

Retrofittable badging and antenna options

Unite* and Highway access covers are the only ranges on the UK market to include provisions for communications equipment, such as antennas, to be installed within the cover.

Antenna in cover linked to hardware in chamber

The ID bolt provision can be used for antennas, allowing communications equipment, such as water meter monitoring, to be installed within a chamber beneath a cover whilevproviding a strong signal above ground without the need to dig or adjust the surrounding road surface. Saving significant time, effort and money while minimising disruption.

Years of exceptional performance

Our Highway D400 covers are still operating at full capacity after three and a half years of being subjected to high levels of HGV traffic. Meaning the organisation can focus solely on new work, rather than being distracted by manhole covers that have failed prematurely and need fixing or, in some cases, reinstalling.
