Used GSI Equipment Sold by Meadoworks

Grain Systems Inc. (GSI) was established in 1972 in Assumption, Illinois, when Craig Sloan and a team of three workers began fabricating corrugated steel storage bins in a 5,000-square-foot garage. From those modest beginnings the company grew rapidly, and by 1988 it had become one of the largest steel bin manufacturers in the world. In 2011 AGCO Corporation acquired GSI for approximately $928 million, integrating it as a dedicated grain storage and protein production division while keeping its Assumption, Illinois headquarters and independent dealer network intact.

GSI's core product line centers on bolted corrugated steel silos and grain bins engineered for both on-farm and large-scale commercial storage. The 40-Series flat-bottom bins are the flagship farm storage offering, featuring high-tensile steel sidewalls rated to 70,000 psi, the precision Z-Tek roof system, and capacities ranging from 1,000 bushels up to 1.9 million bushels across diameters reaching 156 feet. For commercial-scale operations, the EVO 50 and EVO 2X series raise the bar further: the EVO 2X doubles the length of each sidewall sheet on bins 90 feet in diameter and larger, cutting vertical seams by 50 percent and reducing bolt count by half to minimize water intrusion points. GSI also manufactures hopper-bottom tanks in four configurations — BFT, GHT, FCHT, and NCHT — covering everything from small bulk feed storage to large-diameter commercial load-out applications.

GSI silos and bins serve a wide range of end markets. Commercial grain elevators, grain merchandising co-ops, and ethanol processors rely on large-diameter GSI storage to manage high-volume throughput year-round. On-farm producers across corn, soybean, wheat, and other commodity crops use the 40-Series line to capture harvest-time pricing flexibility. Feed mills and livestock integrators depend on GSI hopper tanks for reliable feed storage and delivery, while export terminals and food-grade processors specify GSI commercial bins for their structural consistency and corrosion-resistant galvanized steel construction.

Buyers seeking used GSI silos on the secondary market are drawn primarily by the brand's reputation for structural longevity. Galvanized bolted steel construction resists corrosion for decades, and the standardized bolt-together design means panels and hardware remain widely available through GSI's extensive global dealer network. Because the bins are modular and field-assembled, used units can often be disassembled, transported, and re-erected at a new site — a significant cost advantage over poured-concrete or welded alternatives. The combination of proven build quality, broad parts availability, and strong name recognition in the grain industry gives used GSI silos lasting resale value.
