For strength, durability and long-term value, the Westeel 3609 stiffened silo is in a class of its own. With 100mm wide corrugations, and G115 galvanised steel, Westeel silos are heaver and stronger.  The Westeel wall sheets are rolled from high strength 65,000 PSI tensile steel.
Specifically engineered for exceptional sidewall strength, stiffened sidewalls are over
2½ times more efficient at achieving the maximum load possible out of each pound
of steel as compared to competitive unstiffened bins. It also features a more precise, cleaner assembly without unsightly welds for a super-tight fit.
