Composite Manhole Covers

Manhole cover solutions for every sector

Our manhole covers come with a standard C250 (25 tonne) load rating, perfect for areas with slow-moving traffic. But if you need heavy-duty performance in areas with intense wheel traffic like diesel lanes or bus depots, our covers offer a D400 (40 T) load rating. And if you have specific load rating requirements, we can cater for load ratings from B125 (12.5 T) all the way up to E600 (60 T).

We also offer custom covers that can be produced in any colour you prefer. If you want to add your own logo or markings on the cover’s surface for product or brand identification, no problem!

When it comes to retail fuelling, ThruBeam leads the way, with one of the widest range of composite manhole covers on the market today. Our watertight, easy-to-remove composite manhole covers are available in various shapes and sizes, including general tank sump access, multiport and single port fill sump applications.

Innovative design with our patented ThruBeam technology

Our innovative design features our ThruBeam patented internal structure that allows us to offer a wide array of shapes and sizes without compromising load-bearing capacity. In fact, our high-strength one-piece moulded design is the only one in the industry that can provide multiport or single port composite covers.

When it comes to strength and durability, ThruBeam is the specifier’s choice. Designers often specify our manhole covers for applications with heavy wheel loads or for customers who require long-lasting products. Unlike cheaper imitations, ThruBeam’s covers are built to last, providing excellent performance years after installation.
