Radio signals transparency

Composite manhole covers have a minimum radio frequency interference. The tests carried out by a specialized laboratory confirmed that the signal reduction caused by composite covers is very low. Communication infrastructure workers can quickly check the positioning of networks with RFID systems.

light

The composite manhole covers are up to 60% lighter than the ones in cast iron. Their lightness ensures an easier handling during the installation phase as well as during the maintenance, providing significant time, workforce and means savings. The installation could be indeed safely carried out by a single worker. Moreover, the reduced weight cuts down substantially the transport costs.

No deformation

Since the elongation in spheroidal cast iron can reach up to 18%, deformation issues may arise during inspection and maintenance.

Thermal insulator

If place in contact with a heat source, the FRP cover takes much longer time to warm up than an iron cast cover.

Theft prevention

FRP manhole covers have no monetary value, while iron cast ones may be sold to scrap metal dealers. Therefore, composite covers prevent not only the possible accidents caused by cover thefts, but their replacement costs.

NOISE REDUCTION

Composite covers considerably reduce the noises caused by imperfect match between lid and frame or installation mistakes. Due to this, the passage of vehicles or people may produce noise issues. Iron cast covers are often subject to this problem indeed.

Antislippery

The upper surface of cover has relief designs realized according to EN 124 that guarantee the safety standards even in case of bad weather due to the anti-slip characteristics.

Electrical insulator

The composite manhole cover is non-conductive, so it protects pedestrian from possible electric leakages, especially in humid or wet environments.

Thermal insulator

If place in contact with a heat source, the FRP cover takes much longer time to warm up than an iron cast cover.

Thermal resistant

M.M.’s covers are perfectly suitable to extreme weather conditions since they resist to a range of temperature from -40°C up to 100°C.

Scratch-resistant finish

Special scratch-resistant knurled finish.

Corrosion resistant

Composite covers are not affected by corrosion or by chemicals since the surface is entirely made of a chemical resistant thermosetting resin.

UV resistant

Thermal resistant

M.M.’s covers are perfectly suitable to extreme weather conditions since they resist to a range of temperature from -40°C up to 100°C.

customizable

Upon request we can customize the cover with logos and patterns. The design resolution is better than manhole covers made of different materials, such as iron casts.

RESPECT FOR THE ENVIRONMENT

The production process requires lower energy consumption than iron cast covers.  FRP manhole cover may be recycled through a mechanical process and reuse for by-products.
