GVA Krefeld GmbH provides solutions for all aspects of foundry technology, from the design of special components to plant construction and complex projects in the steel industry.
In over 35 years of company history, GVA Krefeld has always grown with the times and has transformed itself into what it is today. We now operate at locations all over the world. Our customers include large corporations as well as medium-sized companies.
The foundation for this great story was laid by Karlheinz Näser in 1987 as co-founder of GVA Krefeld GmbH and pioneer of today's modern slag pots for steelworks.
From these roots, our company has developed into an engineering service bureau and trading company with a portfolio ranging from castings and forgings to welded constructions.
We see ourselves as a full-service provider, delivering project management from a single source, from conception to handover of the ready-to-use product.
Quality is our top priority. This applies to us as well as to our contractual partners and suppliers. This philosophy has ensured stability in the past and will continue to ensure a sustainable selection of partners and a stable network in the future.
