Prime Agriculture can meet all customers’ needs for commercial silo applications, with the wide range of SPP silo models, from 3.64 up to 31.83 metres diameter.


All silo major components are manufactured with highly automated continuous ‘de-coiling’ process techniques, ensuring fast & accurate production.


The cylinder is constructed from galvanized corrugated steel sheets with profiled external galvanized vertical stiffeners.
The standard sidewall sheets and stiffeners are manufactured from 0.8 mm through to 3.5 mm galvanized, (minimum 450 g/m2 steel with a tensile strength up to 420 N/mm2 & a yield stress up to 350 N/mm2.


When required, higher steel grade material and galvanization up to 600g/m2 can be offered to suit clients’ specific requirements.
Where necessary laminated sheets are used to meet the calculation requirements.


The profiled stiffeners carry the vertical load of the silo to the base, the stiffeners feature strong bolted splice joint plates with a large cross sectional area, critical elements in stiffener design.
All sidewall sheets are assembled with high strength grade 8.8 bolts, with a spun galvanized coating, guaranteed against corrosion & stainless steel/rubber washers.


The use of ‘strip’ sealant for both horizontal vertical joints ensures a perfect seal between sidewall sheets & fixings.


The  range of silos are suitable for all free-flowing cereals including wheat, maize, barley, rapeseed, soya beans etc & can be offered according to ASAE/ANSI, DIN 1055 Part 6 & Eurocode design standards, also taking into account the local wind, seismic & snow load requirements.
