Control cabinet manufacturing for industrial companies

A company built on robust processes

From one-off to series, every solution should be technically traceable, properly coordinated and suited to its intended use. To achieve this, we combine personal project support with defined manufacturing and testing steps.

Who is Gross Schaltschrankbau?

Gross Schaltschrankbau is an owner-managed control cabinet manufacturer for industrial customers, based in Ditzingen. Engineering, switchgear manufacturing, and testing and quality assurance all come from a single source and can be ordered individually or as a continuous process chain. We manufacture everything from one-offs and assemblies to series production – based on approved documents and with manufacturing and testing steps defined in advance. What sets us apart is the combination of skilled craftsmanship and defined processes: every project has a dedicated contact person, every technical decision a documented basis.

Profile

What defines us

Four characteristics that customers mention again and again.

Dedicated contact person

Technical clarification, scheduling and queries are handled by one person – from quotation to handover.

Engineering and manufacturing in-house

Design, schematic creation and manufacturing are under one roof. Questions from the workshop reach engineering directly.

From one-off to series

Prototypes, assemblies and repeatable series are manufactured with the same testing methodology.

Documentation you can rely on

Layout, marking and documents should remain usable for maintenance and expansion years later.
