RESISTANCE TO DEFORMATION AND STRENGTH
Composite Manhole Covers
Fiber flex designed the composite manhole covers mainly due to the numerous benefits of
composite covers over the heavier alternatives (namely steel and concrete) as well as the
metal theft epidemic. The composite covers have no scrap or resale value making them unattractive
to thieves.
Fiber flexes composite manhole covers and frames comply with the EN 124 standard. The
EN 124 standard was published in 1994 and was essentially a standard for cast iron manhole
covers that took little account of other materials such as composites. The inherent properties
of composite materials make them ideal for the manhole environment. The EN 124 standard
is currently in review and the essential characteristics for the standard. Fiber flex has been at
the forefront in incorporating these characteristics into the design of the composite covers.
The Fiber flex composite manhole covers are manufactured locally using a technologically
advanced composite manufacturing process to create a highly engineered, incredibly strong
composite product. The composite covers are available in a range of sizes and load ratings.
Key benefits offered by Fiber flex composite manhole covers over their steel and concrete
counterparts cover an array of technological advances and cost savings including higher
quality, improved safety, greater longevity, lower life cycle costs (LCC) and a greatly reduced
risk of theft. Due to the light weight of the composite covers there is no need for cranes and
other heavy-lifting equipment.
Unlike cast iron and steel manhole covers, the composite
covers are non-corrosive and non-conductive.
The composite covers have a unique skid resistant
surface and will not spin-out, making it safe for road
use purposes and designed as a “fit and forget” product
for civil engineering applications. Unlike concrete
manhole covers, the composite covers will not crumble
or crack.
