RAW MATERIAL: Symaga manufactures in galvanized corrugated steel, with a 600 gr/m² coating and ZM310 gr/m², ensuring a double service life more than other suppliers do.

CALCULATION OF THE STRUCTURE: Silo calculation is made according to different norm as ANSI – ASAE EP 433 2033, EUROCODE EN-1991-4, or any different required norm. Technical Data. Calculations Standards


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.
