Ventilation Grates

Via a special aeration system, ventilation grates create air flow. They combine functionality, stability and cost effectiveness, in one component.

The characteristics of ventilation gratings lend themselves impressively to the agricultural industry. By virtue of their high air permeability, they are very well suited to the ventilated storage of dry bulk goods. Ventilation gratings are ideally suited to the storage of grains and animal feed in silo installations.
