	Commercial Hopper Tanks Commercial hopper tanks are typically used in applications where routine clean out is required, or simply to reduce the energy and labor cost of material handling. Whether you're looking for wet or dry grain holding, overhead unloading systems, blending bins, or long term grain storage, GSI has a full line of commercial hopper tanks to meet your needs.				CHT Specifications -------------------- Commercial Hopper Tanks -------------------- CHT Roofs -------------------- Easy Tank Access -------------------- Grain Aeration / Conditioning Strong Connections Panels are assembled using graded, zinc plated, dichromate coated bolts with sealing washers for a tight, weather resistant seal. Tank Columns are fully reinforced with strong "X" bracing, standard high-tensile strength rods or heavy-duty, structural steel bracing, depending on the tank size, stored products and special wind or seismic load conditions. Easy Access Door A standard 24" diameter round access door is located in the second ring of all GSI commercial hopper tanks.

			NCHT and FCHT Series GSI offers two series of commercial hopper tanks , the NCHT series with a strong 2.66" sidewall corrugation, and the shorter FCHT series with a wider 4.00" sidewall corrugation. The NCHT series encompasses a full range of diameters ( from 15' to 36' ), capacities ( up to 53,659 bushels (1513 MT)), and hopper slopes (40, 45, and 60 degree) to meet virutally any hopper storage requirements. The FCHT series is available in a 45 degree hopper slope and is designed to cover a more specific "intermediate" range of capacities providing the strength and reliability of a stiffened tank and the cost advantage of a series designed for a specific limited size/capacity range. All sidewall is roll-formed at the GSI plant for consistency from commercial coated galvanized steel for increased durability.

			Tank Stiffeners GSI commercial stiffeners are manufactured from high tensile strength 65,000 PSI (450 MPA) steel and completely galvanized for durability. Stiffeners feature strong splice joints with large cross sectional areas, both critical elements of vertical stiffeners, and are installed two-post (two per sidewall panel) externally mounted to bear directly on the base columns. Solid Support GSI CHT's start at the concrete foundation with heavy structural "wide flanged" columns, factory welded to thick stell base plates. Columns are cleaned, specially primed and painted for durability. Bolted to the top of each column are heavy compression angle segments, key components that join the columns, the hopper assembly and the tank body together as one complete unit.



			Heavy Wind Rings For additional support with taller tanks or higher wind areas, GSI manufactures galvanized steel rings that attach directly to the tank stiffeners. The rings help control shift in the sidewall and/or stiffeners due to strong winds which can cause extensive damage over time, reducing the life of the tank.

Hopper Slopes

	Hopper Strength and Options Strength of the tank hopper is extremely critical to the life of the complete tank. For this reason, each hopper panel is precision fabricated from high strength commercial galvanized steel and designed for maximum support when assembled. Hoppers are available in a variety of slopes to match the correct tank size and required application. Both 40 and 45 degree hoppers are generally used with most dry whole grain products. A 60 degree hopper is often used for "wet holding" or other applications where a 60 degree is better suited.

			Optional Roller Valve An optional, roller valve assembly is available designed to attach directly to the hopper discharge collar. Roller valve gates are equipped with machined rack and pinion gear sets controlled by either a hand or chain wheel. All galvanized construction, the GSI roller valve is simple to operate and provides years of trouble free service.
