Recessed Composite Manhole Covers are manufactured from very light, very strong, maintenance free composite material. They have a superior durability which means a life span of 50 years compared to only 25 for galvanised steel, with only cosmetic maintenance requirements.
Composites exhibit excellent corrosion resistance and are fire retardant. They are 30-45 % lighter than aluminium when designed to the same functional requirements.
The recessed tray type will be produced with a high tech bonding surface on the internal faces of the covers, an advantage for better bonding with concrete.
Available in 2 depths - 60mm and 86mm.
