Hannover Messe is the worlds defining industrial trade fair. Each year it gathers approximately 4,000 exhibitors and 130,000 trade visitors from over 90 countries to Hannover, Lower Saxony, for what has become the most important meeting point for industrial automation, energy systems, intralogistics and digital manufacturing.
Industry context
The fair was founded in 1947 as a vehicle for post-war German industrial rebuild and was nicknamed the "fish sandwich fair" because food-rationing exemptions made the venue catering unusually generous for visitors. Today it operates as the principal annual benchmark for industrial Industry 4.0, hydrogen-economy, electric drives, robotics and automation companies. Each edition features a single "Partner Country" - recent partners were Indonesia (2023), Norway (2024), Canada (2025) and Brazil (2026); the 2027 partner is yet to be announced at time of writing.
Exhibitor profile
Roughly 60 percent of exhibitors come from Germany, with the remaining 40 percent split across Italy, China, the Netherlands, Spain and the US. Sectors represented include factory automation, motion and drives, energy and storage, industrial supply, digital ecosystems, robotics, compressed air, and engineered hydrogen systems. Stands at Hannover Messe trend technical and engineering-led: working demonstrations are expected, glossy marketing is not.
Visitor demographics
Visitor seniority is unusually high - over 80 percent of attendees hold purchase-decision authority or direct procurement influence within their companies. Visitors come from manufacturing, plant engineering, energy, automotive, chemicals, food and beverage, and increasingly defence and aerospace sectors. Roughly half travel from outside Germany.
What makes the stand build different here
The Hannover scale demands more freight movements, longer build cycles and tighter electrical infrastructure than smaller shows. Most exhibitors bring functioning machines, not models - which means floor loads, three-phase power, compressed air, and water/drain connections are routinely required on the stand. Build-up runs typically seven to ten days. The Partner Country exhibits are sited in dedicated halls and often involve government delegations, which raises security requirements.
Hall map summary
Halls 2-7 host the heavy-machinery and motion-and-drives exhibitors. Hall 8 anchors digital factory and software. Hall 11 houses energy solutions and hydrogen. Hall 12 covers compressed air and steam. Halls 13-15 host industrial supply. Hall 19/20 are the outdoor demonstration zone.
