M.M. solutions for shipyards

In shipbuilding, the choice of materials is critical to ensuring the safety and durability of ships and vessels. M.M. FRP gratings – Fibreglass Reinforced Polymer – are designed to meet these needs and are also used on large vessels such as:

oil tankers
LNG/LPG carriers
chemical tankers
military vessels

Lightness and resistance to seawater

One of the main advantages of M.M. gratings is the lightness of the material, an essential aspect in the design and construction of large ships.
The isophthalic resins used by M.M. to manufacture FRP gratings also retain their chemical and mechanical properties unchanged after 10 years of immersion in seawater at 50°C, ensuring high resistance to marine corrosion.
Unlike galvanised steel gratings, FRP gratings do not corrode and withstand the combined action of water, salt, ice and dirt: this translates into a drastic reduction in vessel maintenance costs and a significant extension of their service life.

A further advantage lies in the workability of the gratings, which can be carried out directly on board. Thanks to the availability of standard gratings in stock, they can be cut to size on site according to requirements, with no need for special equipment or welding operations.

FRP gratings: certified performance

For a selection of gratings, M.M. holds the Type Approval Certificate issued by BUREAU VERITAS, certifying their suitability for use on board ships. In addition to self-extinguishing polyester resin gratings classified L0, M.M. also offers L2 – structural fire integrity classified phenolic resin gratings, compliant with the ASTM F3059 standard, for use in:

lifeboat embarkation areas

escape routes on open decks or semi-open areas

A cost-effective alternative to AISI 316 stainless steel

FRP grating represents a more cost-competitive solution than AISI 316 stainless steel, offering similar performance with lower production and installation costs.
