The primary function of a polymer (plastic) manhole cover is to protect all utilities, sewerage, and drainage system shafts from possible damage or contamination, as well as to provide easy access to water supply wells, sewerage and stormwater systems.
The polymer manhole covers are easy to install and operate. Locking devices on each cover ensure the safety of children and any tampering.
The plastic manhole consists of:
manhole cover;
manhole body.
The manhole plastic covers are made from a specific high-strength composite, of high and low-pressure polyethylene.
Polyethylene does not deteriorate under the influence of ultraviolet (solar) radiation, it does not corrode, or freeze in winter. Operating temperature ranges from minus 50 to plus 50 Celsius degrees.
Easily withstands any dynamic and static loads.
Doesn't sink into the water.
All our manhole covers are fully recyclable.
