Harvesting & Storage > Grain Storage
2.66 GSI Farm Bin Photograph

The Grain Systems "Narrow" series farm bins and silos are the original Grain Systems grain bin/silo line. A unstiffened series , this line is a popular choice throughout the United States. With 32"(813 mm) tall sheets it is easy to construct and is built from the strongest steel used in the grain bin and silo construction industry.

Grain Systems "Narrow" Series Features:

  • ASTM A653 SQ Grade 40 (55,000 psi tensile) Steel used for the roof panels and 18 gauge and thinner sidewall.
  • ASTM A653 SQ Grade 50 (65,000 psi tensile) Steel used for 17 gauge and thicker sidewall.
  • Grain Systems's patented two ring door, standard in all bins up to 12 rings tall.
  • Plenum punching for standard floor location and for other floor heights when ordered.
  • Roof panels pre-punched for the Grain Systems Slimline roof vent.
  • Roof manway access and roof ladder.
  • Large Center Dome cap.

The "Narrow" series is produced in three series, the NSL series for general storage and drying, the NHL series for more aggressive drying (and in certain cases the use of multi-auger stirring devices), and the NRL series for use with grain recirculating systems. For more information on each series and its application please visit our FAQ section on the farm storage bins and silos.
