Structure et construction de la serre.
La fonction première d’une serre est de protéger les cultures de valeur des conditions extérieures — prolonger la saison de culture tout en laissant passer la lumière du soleil, essentielle.
Protéger vos cultures de valeur
De leurs modestes débuts comme protection contre les facteurs extérieurs, les serres néerlandaises se sont développées en installations de culture de haute technologie. Les progrès technologiques permettent de cultiver hors saison et d’approvisionner les marchés du monde entier en produits alimentaires et en fleurs, chaque jour de l’année.
Avec les améliorations des systèmes de climat, de culture, d’irrigation et d’automatisation, la construction elle-même s’est considérablement améliorée pour les faciliter et les protéger. Les progrès de la construction améliorent directement le contrôle climatique — en particulier dans les grandes installations conçues pour capter un maximum de lumière.
Une construction complète, dès les fondations
Comme la plupart des bâtiments, la structure de la serre se compose de cinq éléments principaux : fondations, ossatures, bardage, fenêtres de ventilation et systèmes de drainage — construits en béton, acier et aluminium, couverts de verre, de panneaux sandwich ou de polycarbonate.
La construction néerlandaise regorge d’éléments polyvalents. Le toit typique en forme de V fait aussi office de système d’évacuation des eaux de pluie, entièrement intégré à la structure ; le bardage lui-même fait partie de la gouttière.
Comment une serre est construite.
La séquence de construction de la structure de la serre, étape par étape.
1. Foundation
Every structure starts with a foundation. In most cases a lightweight foundation suffices: boreholes and a perimeter tie-beam, filled with concrete and prefabricated steel foundation posts.
Foundation →
2. Steel + aluminium + ventilation
Before erecting the steel structure, the ventilation mechanism is mounted to the trusses. The aluminium gutter between trusses is a critical structural element, erected together with the steel.
Steel structure →
3–4. Rainwater + service building
Weather is anticipated during construction: rainwater is managed before the roof goes on. The sandwich-panel service building is built first, enabling material storage and early installation work.
Service building →
5–6. Glass covering + insect netting
Glass roof covering and ventilation windows are installed simultaneously; sidewalls follow after the roof. Insect netting closes the sequence — finished before screening works commence.

Questions sur la construction de serres
What is the primary function of a greenhouse structure?
To shield crops from external elements while permitting essential sunlight to reach the plants — a barrier against harsh weather that maintains an environment conducive to growth.
What are Dutch greenhouses made of?
Durable materials: concrete, steel and aluminium for the framework, enclosed with glass, sandwich panels or polycarbonate.
Which materials are used for the structural elements?
Concrete for the foundation, steel for the sub-structure and aluminium for the super-structure — robust and functional.
How is the greenhouse structure built?
Foundation first, then the steel structure with aluminium gutters and ventilation mechanisms, integrated rainwater management, a sandwich-panel service building, and finally glass, ventilation windows, sidewalls and insect netting.
