For more than 100 years, our company has stood for high-quality sheet metalworking and first-class tank and vessel construction. Today we only process rustproof materials and have more than 50 years' experience of stainless steel processing. We consistently focus on quality and customer orientation in every aspect of order processing. We are always happy to help our customers to find solutions to problems. We plan and design the components individually to your specifications using our 3D-CAD system. We also produce to your own drawings.


Whatever aspect of Raff + Grund's knowledge you want to draw on — we are pleased to help. Whether it is the layout of your plant or component, the design, laser cutting, the complete production, the surface finish or pickling and passivating. At Raff + Grund you get everything from a single source, from the design to delivery.

We have a certified quality and environmental management system. We are an approved manufacturer for the construction of pressure vessels, a recommended specialist company to §19.1 WHG (German water management law) and have manufacturer qualifications for the welding of steel components. In addition, diverse measuring instruments are available to ensure quality and documentation.

Good employee training is very important to us. Our trainees have been national or state winners of vessel and apparatus construction apprentice competitions more than ten times.
