The best-selling highway ironwork productsThe core range consists of D400 manhole covers and gully grates which incorporate a number of performance and safety-enhancements. Bearing the BSI Kitemark, Tristar fully complies with the BS EN 124:2015. Its many benefits include:
The indexed manhole covers can only be installed one way, eradicating the possibility of installation mistakes and maintaining cover to frame seating compatibility. Unique to Wrekin, the high-seated cover reduces wear on the frame, prolonging service life. Tristar is also fully compatible with our other key enhancements, including the manhole frame-raising system Clicklift and the Armadillo protector shells that prevent damage to your ironwork, reducing the need for replacements and reduces the carbon footprint of installations. This best-selling range is ideally suited to housing and commercial developments, where it will provide a long life and reduce any inconvenience often caused to residents and road users.

Do you need to upgrade to a CD 534 v0.1.0 compliant access cover?National Highways CD 534 specification has been updated v0.1.0 and comes with new requirements. Over 1,500 Annual Average Daily TrafficE600 manhole covers are 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. Check your road traffic stats. Frame weight and depth requirementsFollowing the regulation changes, a lower limit of frame mass has been specified to ensure frames are stiff enough to resist the loads on National Highways managed roads. Alongside this, a frame depth of 150mm is now required on all installations on motorways, and all-purpose trunk roads. Take your installation to the next levelTristar is fully compatible with our groundworker package, which offers groundworkers, specifiers and house builder significant time and cost savings, while improving the general publics attitudes toward road works.
Promoting responsibility with Britain's waterwaysThe Sea Starts HereWe're promoting awareness of a simple but important issue on our most popular Tristar D400 gully gratings. Did you know that waste disposed of down gullies, whether at a roadside or pedestrianised area, can end up in the watercourse. This includes rivers, brooks, becks, ditches, leats and culverts. Ultimately, it has the potential to reach the sea, meaning the sea often really does start here. In collaboration with a long-standing house building client, we've taken the notable step to include "The Sea Starts Here" as a message on our highest selling Tristar gully gratings. The message serves as a poignant reminder that our actions on land reverberate to our oceans. 
Manhole cover frame raising systemClicklift compatibleClicklift eliminates the time and resources required to dig out and reinstall frames to suit the final adoptable surface. This eliminates the potential damage to manhole covers during construction and removes the potential for residents claims for damage to their vehicles and massively reduces disruption. Clicklift provides housing developers with huge savings in terms of time, money and hassle. Allowing whole estates to have their covers raised to the final surfacing level, in as little as a few hours. 
The hard hat for your ironworkArmadillo compatibleArmadillo is a complete range of protector shells, designed to be placed over manhole covers and gully grates to provide enhanced protection during the construction phase. Armadillo provides protection from construction site traffic, including tracked vehicles, and can be easily removed when the final surfacing is completed. This ensures manhole covers and gully grates can start their service life in ‘as new’ condition to optimise longevity.
