Every silo we make, in one place.
Galvanised-steel silos and conveying, sized to the space you have and the volume you need. Start with the shape — each format lists the fuels it stores.
Four silo formats.
Every silo we make is one of these four shapes. The render is the manufacturer's own — the numbers are the real span of each family.

All 72 models across the four formats. Start with the height you have available — it is the constraint that decides most projects, and capacity does not determine height.

Model codes carry the spec: W1022 = 10.0 t on a 2 m × 2 m footprint; W102-4 = 10.0 t on 2.4 m square; C16060 = 160 m³ on 6.0 m diameter. (W102-4 and W1024 are different silos.) Round-silo volumes are being re-confirmed with BSS engineering.
Storage matched to the fuel.
Pellet, chip and waste wood each handle differently. The fuel sets the storage and discharge approach.
Wood pellet silo systems
Keep your pellets dry, free-flowing and ready for the boiler. We size the store, the discharge…
Wood chip silo systems
Chip is bulkier and less forgiving, so delivery access, footprint and handling matter from day…
Waste wood silo systems
Waste wood varies, so we start by checking it suits — then design the storage and handling…
