MobilityWhether in automobile, railway construction or shipbuilding: steel and components from

our group of companies are used precisely in those areas where the strain is greatest, where

performance is produced or transferred and where safety plays a particularly important role –

for example in the power train of road vehicles, in large engines for shipbuilding or wheel sets

for rolling stock.

EnErgyour companies supply essential components for the construction of turbines and generators

used in the classical generation of electricity. in the area of alternative electricity generation,

they are involved in the planning and construction of steel constructions for offshore wind

parks. Furthermore, they produce light alloyed and high alloyed steel casts for fittings and

pumps for the oil industry. their innovative potential is evident in all areas, most particularly

in the development and optimisation of suitable materials.

MEchanical EnginEEringour companies supply steel materials and ready-to-install components to this very large and

varied market. We also produce crane systems. complex transport and materials handling sys-

tems (for example bridge and gantry cranes) are an important feature in our product portfolio.

raW MatErialS rEcycling buSinESS unitIn addition to raw iron, scrap is the second basic material for steel production. In some cases it is the sole material used. The manufacturing cycle of all metal products starts and terminates in the companies of the raw materials recycling business unit. All steelworks and foundries belonging to the GMH Group are supplied with scrap of different varieties and quality grades from this source. Furthermore, third industrial businesses also number amongst our customers in this sector. A fundamental rule applies here: not all scrap is the same – and it is certainly not to be treated as rubbish. The collecting, sorting and processing of different kinds of materials require a high level of technical know-how and sure instinct on the part of our employees.

In order to transport several thousand tons of steel scrap on a daily basis, and to supply customers punctually at realistic market prices, an optimum infrastructure is essential. This is why the Group’s scrap-recycling locations can all be reached by road, rail as well as by waterway. Naturally the core competences of the raw materials recycling business division also includes disposing of scrap which accumulates in crafts trade enterprises, with private persons, as well as in the metal-processing industry.

The piece weights range between a few kilograms and 50 tons. The product range extends from thin walled, weldable and high-strength construction parts to expendable parts such as shredder hammers and grinding balls. In the areas of civil and underground engineering as well as bridge-building, steel casting parts from these companies are used as crotches, cable heads or cast-steel nodes, which are also used for foundation structures for wind turbines. Scoops or diffusers measuring four to six metres in diameter can be supplied for turbine construction. A further core activity in the steel castings area is the manufacture and processing of castings for fittings and pumps as well as for rolling stock construction and mining. Also in the area of construction weldings it is possible to supply solutions which are tailor-made to suit individual customer requirements.

Complicated and core-intensive iron casting parts weighing up to 160 tons can also be produced by the companies belonging to the castings mechanical engin- eering business unit. Hand-formed large-scale casting parts include, for example, cylinder blocks, housings for gas and steam turbines, rotor hubs and panels for wind farms. parts are produced for areas such as energy technology, the steel industry as well as mechanical, compressor and plant engineering. Naturally we are also in a position to produce small and medium series either as semi-finished or finished castings. They are used in railway drive systems, in the food industry as well as in the construction of packaging machines. Depending on the field of application, iron castings with spheroidal or flake graphite are used. The manu-facturing range extends from one-off product to the standard model. Intensive consultancy concerning construction and materials as well as optimisation of the components also constitute an important part of the service provided by our companies.
