What Neptunus does

Neptunus Group B.V. is a Netherlands-headquartered industrial rental and engineering company founded in 1937 that designs, rents, and constructs demountable buildings and event tents. Its core technology is an aluminum modular structural system using PVC or glass panels, membrane roofing, and cassette flooring, supporting a product range from 10m² to over 20,000m² across two main lines: semi-permanent demountable buildings (Flexolution III/II, Evolution, Alure Globe, Aluhal) and event tents (Aluhal, Alure family, Pagodetenten, Etagehallen multi-floor structures, Mercurius/Saturnus, Pluto/Mars/Jupiter). Proprietary components include the regengootafspanning (rain gutter system), cassettevloer (cassette floor), and membrane roof construction.

The company generates revenue through a dual model of rental subscriptions and outright sale, with quote-based pricing and multi-year contracts and customization options such as logos, house colors, and panel choices. Distribution is via direct enterprise field sales and account managers operating from wholly-owned subsidiaries in the Netherlands, Belgium, the UK, Germany, Austria, France, and Poland, supplemented by channel/partner relationships (e.g., official supplier status with Sportcentrum Papendal). Customer segments span sports and event venues, retail and supermarket chains, aviation, defense, logistics and warehousing, education, and petrochemical/industrial shutdown operations, with named reference customers including the Olympic Games, Wimbledon, F1, Royal Ascot, Audi, McDonald's, Philips, Red Bull, Action, and Fontys. Operations are held to ISO 9001, ISO 14001, ISO 45001, VCA**, and CO2-Prestatieladder Level 3 certifications, with a documented Scope 1–3 carbon footprint and a target of 25% relative CO2 reduction by 2028 against a 2023 baseline.

Emerging players

Others

• Dancovers: European online retailer and rental provider of tents and event structures. Adjacent to Neptunus on the event-tent side, but serves smaller end customers through e-commerce rather than enterprise sales.
