Gruber Grain Technology builds silos according to the legally prescribed EN1090 standard
Storage technology
Proper grain storage should not be left to chance! Gruber plans and builds the right grain store for your individual requirements. Whether round silo or rectangular silo, whether external silo or internal silo: the grain silo is expanded with silo accessories such as grain ventilation, grain cleaning and conveyor technology for optimal storage technology. With Gruber’s silo technology, moisture damage and pests can be optimally controlled.
We also build silo systems for feed technology: various silo funnels (50° for pellet storage or 60° for meal silo or concentrated feed silo) and square or round silos.
Since July 2013, grain silos may only be built and assembled in accordance with EN1090! Our company has been certified according to EN1090 and continuously monitored by TÜV. In this way, you as the building owner do not run any legal or insurance risks.

In many cases, the smooth-walled round silo from Gruber is the most cost-effective solution of all internal silos. The patented silo system has no bracing on the inside and the silo feet are also completely bolted to the outer shell. This means that there is hardly any dust build-up inside the round silo. The Gruber smooth wall silo can be supplied with a filling volume per silo of 5m³ to 370 m³ or silo diameter 2.25m to 7.5m.

The Gruber smooth wall round silo is one of the highest quality outdoor silos on the market.

Thick silo walls in combination with high-quality sheet metal grades result in a longer service life. Our patented smooth-wall silo has no bracing on the inside and the silo feet are also completely bolted to the outer shell. This means that there is hardly any dust build-up inside the round silo and less wear during emptying. A proven silo system not only for farmers, but also for pellet storage and industry.
