Delivery (Unloading to Truck or Train) Silos

Conical chambers are supplied for wide and high construction for discharging capacity from 27m3 to 267 m3. Evacuation silos usually separated for Daily storage. To load the container, grain is transferred from high capacity silo to discharge silo.

CTS manufacture bulk material storages with a guarantee for longer lifetime more than our competitors, high technologic manufacturing place with maximum strength. Our customer requirements are satisfied with silos from 5m³ to 25.000m³ volumes. The manufacturing of silos is done by channeled galvanized steel with 600g/m2 coating and ZM250g/m2.

All calculations are done with ANSI – ASAE EP 433 2033 or EUROCODE EN – 1991-4 norms or if needed by the customer, other norms can be applied.

Silo Components

Cylindrical Body

Made up of bodysheets and stiffeners, manufactured in structural steel S 350 GD Z600 hot dip galvanized.

Buttyl Rubber Compound

It is supplied in a preformed way to ensure optimal sealing.


Hopper is made up of structural steel S350 GD – Z600, and can be performed with 45º, 60º, or 66º degrees, depending on the flowing of the stored material.


Quality 8.8 and 10.9. Nuts provided are quality 8, and neoprene EPDM washers guarantee sealing. Supplied bolting is hot dip galvanized with (70 – 85 microns), ensuring higher service life more than other suppliers do.

30º Degrees Roof

Composed by trapezoidal sectors. The special geometry of the wave of the roof and longitudinal folds gives high strength and stiffness. Depending on silo diameter, and roof loads, roof can be supplied with our without structure.
