HOPPER SILOS
Our metal hopper silos are the optimal choice for storage and the unloading of grain by gravity.
Essential in sectors such as breweries, feed mills, port terminals, mills, bioethanol, oilseeds, dryers, flour mills, as well as storage of raw material for the plastic and biofuel industry.Diameters
From 3 to 12.23m
Capabilities
From 5 m³
to 2,922 m³
Guaranteed steel
S450 GD with Z600g/m² coating on the cylinder and ZM310 g/m² coating on the roof
Calculation of the structure
In differents norms : ANSI - ASAE EP 433 2033, EUROCODE EN - 1991-4 or in any other required local norm
