Hopper Bottom Silos
The design the Hopper bottom silos is based upon the loads and pressures derived from the German DIN 1055 1987 standard. Structural calculation based upon BS 5950 part 5 and wind loading of 50m/sec (180m/h) for a probability period of 25 years. Wall sheets are corrugated, utilizing shallow pitch corrugation to ease material flow.
Standard ranges from 3.0m diameter 15 tonnes storage to 12.0m diameter 1800 tonnes, all hoppers are designed for high cyclic loading, i.e. high usage of product in and out and at high tonnage rates. 45 and 60 degree hoppers are standard. Entablature steelwork is hot dip galvanised after manufacture, silo roof, wall sheet and vertical stiffener material is manufactured from pre galvanised steel sheet with minimum G600 galv coating.
