There is a reason our silos are bolted, not welded.
It is a question we get asked sometimes. Welding is faster in the factory. It creates a sealed joint. And for many steel structures, it is the obvious choice.
But for modular silos that need to ship globally, install inside existing buildings, and adapt to changing needs over time, welding is actually a limitation.
A welded silo is a finished product the moment it leaves the factory. It ships as one piece, which means higher freight costs, wider transport routes, and usually a crane on site. It cannot pass through a standard doorway. And once it is installed, it stays the way it is.
A bolted silo is different. It ships flat-packed as panels and sections. Freight costs drop significantly because you are shipping components, not air. Every part fits through a standard doorway, so installation happens inside the building without structural changes. Two people can assemble a standard unit on site, using language-neutral instructions. And if your capacity needs change, you add sections to the existing structure instead of replacing the whole unit.
Bolted construction also means full traceability under EN 1090. Every panel, every bolt, every connection is documented and traceable back to the raw material. That level of documentation is increasingly required in regulated industries, and it comes built into the system.
We chose bolted modular construction over 60 years ago. Not because it was easier to manufacture. Because it was better for the customer.
