Mechanical and plant engineering

Efficient lightweight construction, high-performance designs, optimum workability

Mechanical and plant engineering is regarded as the backbone of the German economy – and it is supported by steel

Hardly any other material is as versatile and highly specialized as steel. It can be precisely tailored to customer requirements. Whether related to special hardness or strength, degrees of purity or formability, suitability for welding or corrosion resistance, the diverse properties of steel make it indispensable for mechanical and plant engineering. Our high-quality steel products are used in many applications. These include tool steels for the manufacture of forming tools, shafts and components, die rings and housings.

Megatrend: population growth

Drinking water supply

2.1 billion people worldwide have no access to clean water. To improve this situation, we produce components such as cast steel valves for our customers to transport water in drinking water systems, and cast steel blades for pumps in seawater desalination plants.

Green Steel for mechanical and plant engineering

Low emissions
for a greener future

GMH Gruppe Grüner Stahl Origin Germany

Steel is almost completely recyclable. This alone makes it a sustainable raw material, especially for components subject to wear in mechanical and plant engineering. At the same time, our steels are becoming ever stronger and lighter, making slimmer structures possible. This is how we are helping to conserve resources, reduce energy consumption in production, and cut CO2 emissions.

We are Green Steel

What you can expect

A high level of expertise in tool steel

Our tool steels are used to produce molds for plastic injection molding and die casting machines. They are characterized by key features such as work hardness, tensile strength, machining and wear resistance, corrosion resistance, machinability and polishability – and by the outstandingly high dimensional accuracy of the workpieces produced with them.

A high level of vertical integration, all under one roof

We supply highly machined products for mechanical and plant engineering. These include customer-specific cast cylinder heads, primarily for the industrial engine sector, which are both machined and assembled. We also offer processing options such as drilling, milling, turning, grinding and polishing for many other products.

Materials development for customized solutions

In our Application and Materials Development department, we work closely with our customers to develop increasingly efficient primary materials and ready-to-install components for complex applications.
