MINIMAL RESISTANCE LOAD > 15 kN
Exclusively pedestrian and cycling areas.
Production process
As per EN 124:2015, the production process of our manholes covers falls under class C2 (“Composite material C2” Point 4.2 Type of composite materials). This is a compression molding process made with a closed mold under controlled temperature (SMC) that employs thermosetting resins (polyester resin), short glass fibers (chopped strand) and other additives. The production process guarantees excellent fibers’ wettability from the polymer matrix. Moreover, it avoids air bubbles and creates an excellent interlaminar cohesion between components.
Areas of use
Our FRP manholes covers are designed to meet A15/B125/C250/D400 load ratings’ requirements in accordance with EN 124:2015. Moreover, FRP covers have hardness characteristics similar to cast iron ones, while having better resistance to residual strains.
MINIMAL RESISTANCE LOAD > 125 kN
Sidewalks, pedestrian or similar areas, rest areas and car parking garage.
MINIMAL RESISTANCE LOAD > 250 kN
Areas of drainage channels along the sidewalks that run for a maximum of 0,5m onto the roadway and for a maximum of 0,2m onto the sidewalk.
MINIMAL RESISTANCE LOAD > 400 kN
Roadways (including pedestrian ways), transitable platforms and rest areas for road vehicles of all kinds.

FIBER TOP advantages
Easy installation and inspection
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.
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.
safe
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.
Lasting
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.
and also
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.
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.
