Fiberglass Reinforced Polymer Railway infrastructures
THE COMPANY The railway infrastructure requires constant maintenance and renewal in order to meet the growing safety needs of operators and passengers. M.M. Srl. works with the main stakeholders in the rail sector to search for innovative solutions in terms of products and systems in fibreglass. The intrinsic electrical insulation properties of fibreglass make this material particularly suitable for use in high voltage environments.
ADVANTAGES MAXIMUM ELECTRICAL INSULATION In accordance with the standards EN 61340-2.3 par. 8.1 and 8.2 with ref. to ISO 1853, IEC 60167, HD 568 S1 and IEC 61340-4-5 - IEC 64-4/8/6 par. 6.12.5 IEC 60167 - HD 568 S1, M.M.’s gratings are classified as excellent insulators in compliance with safety standards.
NO NEED FOR GROUNDING OR INSPECTIONS Resulting in lower installation and management costs.
DURABLE AND MAINTENANCE FREE Thanks to their resistance to corrosion, temperature leaps, humidity, UV rays and low temperatures, the mechanical performance of M.M.’s products is guaranteed for 20 years.
LIGHTWEIGHT AND EASY-TO-HANDLE FRP weighs 75% less than steel and has an excellent strength-to-weight ratio.
WORKABILITY FRP products are easy to process in the construction yards and do not require the use of specific equipment.
NON-SLIP FEATURES M.M.’s gratings are classified as slip resistance classes from R10-V4 to R13-V10 in accordance with the DIN 51130 standard; they are suitable for pedestrian and vehicle traffic with all finishes according to the BS 7976-2 standard.
REACTION TO FIRE M.M.’s self-extinguishing products are classified Bfl-s1 according to the EN 135011 standard. A2-s1 (EN 13501-1) and M1 F1 (AFNOR NF P 92-507 and AFNOR NF F 16-101) products can be supplied upon request.
APPROVAL M.M. has obtained the approval by the EisenbahnBundesamt (EBA) – German Federal Railway Authority – to supply Deutsche Bahn (DB) with a high number of gratings. EBA is in charge of more than 38,000 kilometres of railway lines nationwide.

ELETRIC CABLE CONDUITS & PITS M.M. manufactures FRP coverings, which are the ideal solution to cover pits and cable conduits in railway stations and electrical substations. The coverings, featuring a non-slip surface finishing, provide adequate load-bearing capacity for the expected traffic in accordance with the technical specifications of electrical distribution bodies. M.M. can also provide FRP self-anchoring or steel bracketed frames.
CABLE DUCTS M.M.’s FRP cable duct system is ideal for the protection of cables and the distribution of electricity. Maximum flexibility and safety are guaranteed by the intrinsic characteristics of the material and the wide range of modules of different sizes and scales, covers, junctions, reducers, elbows and mounting brackets. The system is the ideal solution for distribution to substations along the line within a tunnel.
COVERAGE OF RAINWATER CHANNELS FRP gratings are an exceptionally valid alternative to traditional materials (concrete and steel) in the construction of rainwater channel coverings. Electrically insulating, they are extremely light to handle and feature high non-slip coefficients; hence, they have all the essential features for use in environments along the line.

PEDESTRIAN LEVEL CROSSINGS FOR SERVICE PERSONNEL OR THE PUBLIC Manufactured with FRP gratings featuring covered or heelproof mesh, with a high non-slip coefficient, mounting clips in stainless steel, adjustable PP supports and cover plates for hanging hooks, these products can be easily adapted to intra-line geometries including railroad switches and can be easily fixed using brackets that can suit any rail infrastructure. Available for a variety of loads and in various colours, they ensure highest versatility and safety.
SLOPED STAIRWAYS FOR ACCESS TO EMBANKMENTS Manufactured using pultruded profiles and FRP gratings, the stairways are designed according to the characteristics of railway embankments in accordance with the requirements of EN ISO 14122-3. Equipped with hand rails and landings, they allow safe access to the tracks for line maintenance operators even in adverse weather conditions. During installation they are easy to handle and adapt to the site conditions without the use of specific equipment.
AN ANSWER TO EVERY NEED
GATES M.M.’s FRP gates, which are made with pultruded profiles and gratings, stand out from traditional steel solutions because they are lightweight and feature high dimensional stability and dielectric properties. With single or double wings, gates are CE marked in accordance with the EU Construction Products Regulation No. 305/2011 and they are tested according to the UNI EN 13241-1 standard.
OVERPASS INSULATION When dealing with the potential danger of contact with medium voltage cables, the electrical insulation of overpasses becomes fundamental. This problem can be solved by using FRP sandwich panels fixed to steel soffit structures by means of threaded FRP rods. The system ensures maximum electrical insulation and requires no maintenance, which is particularly convenient given the difficult access to this infrastructure.
FENCING SYSTEMS AND PROTECTIONS M.M.’s FRP fences are manufactured using pultruded profiles and FRP gratings. They are a competitively priced alternative to traditional materials. They are supplied in pre-assembled modules for easy handling and quick on-site installation with stainless steel base brackets or embedded poles. Shapes, colours and finishes are designed to suit customers’ needs and they combine maximum electrical insulation with high versatility. In addition to their use as permanent fences, they can also be used to temporarily enclose work sites along the line.
OTHER APPLICATIONS • Provisional platforms: custom-tailored structural solutions designed to make sure that stations remain fully operational during the various construction stages. • Access stairways and railings for platforms, electrics and signalling: they provide easy access and electrical insulation, thus ensuring the safety of workers in all conditions. • Dielectric protection for rail overpasses railings: they prevent accidental contacts by pedestrians with potentially under-tension barriers and steel railings.
• Dielectric protection for metal frameworks: made from FRP laminated elements shaped to measure. • Dielectric protection for counterweighing • Non-conductive interruptions for existing metal railings and fences
MAINTENANCE WORKSHOPS - WASHING STATIONS
WALKWAYS FOR SERVICE PITS M.M.’s gratings are the perfect choice for the walkways in service pits thanks to their ease of handling and durability, as well as their high non-slip coefficient even in the presence of oil.
WALKWAYS FOR WASHING STATIONS M.M.’s FRP gratings are the perfect choice for walkways in train washing stations as an alternative to traditional materials. The lightweight modules of FRP gratings, which facilitate removal for cleaning, and their resistance to chemicals, temperature leaps and humidity certified according to UNI EN ISO 9142/04 make them the ideal solution for this type of application.
