Mountings for marine vessels
Metalastik marine mountings are used in naval, merchant marine and leisure vessels, cruise liners and fast ferries, luxury and light craft. They are specified for primary propulsion and auxiliary engines as well as for ancillary duties, such as mounting reduction gears, pipework, ventilation, compressors, pumps, sewage treatment units, refrigeration units and even sound systems.
Marinised generator sets
The company offers exceptional expertise in the field of marinised generator sets. Applications range from the largest machinery rafts and custom-designed offshore installations, right down to instrument panels.
Shock attenuation and vibration isolation for marine vessels
Trelleborg Industrial AVS also offers unsurpassed experience in shock attenuation and vibration isolation for naval and coastguard applications. This ranges from pilot vessels and assault craft to helicarriers, supply ships and hydrographic / research vessels to the specialist and anti-magnetic technologies required in mine-hunting, nuclear submarines and modern frigates. At the top end of the scale, Metalastik mounts are specified on the latest UK Astute class submarines, as well as the flagship French nuclear aircraft carrier.
Elastomer expertise and rubber formulations
In addition to its wide range of marine-specific products, Trelleborg offers a unique reservoir of elastomer expertise and what is probably the most extensive catalogue of rubber formulations in the industry.
This and the experience embodied in our expert teams of development and applications engineers is the key to Trelleborg’s marine offering. It is a combination of design skills and manufacturing excellence that ensures Trelleborg Metalastik products not only work first time, out of the box but also offer long, trouble-free service and proven whole-life cost benefits.
The company’s headquarters are located in its state-of-the-art plant in Leicester, UK, which also houses the core technical resource and its research and development unit. Production is divided between Leicester, Carmi in the USA, Delhi in India and Wuxi, in China, where there is also a highly developed engineering and sales support team.
The Trelleborg strategy is to make the company’s technology available on a local basis in all the world’s major marine markets. This is achieved through technical innovation, a cross-disciplinary sales organisation with dedicated engineering back-up and, thirdly, local manufacturing, particularly in Far Eastern markets to achieve a high level of local content.
