With a commitment to quality products and service, Country Grain Systems has the most complete line of grain storage, drying and handling equipment, systems and accessories available from one manufacturer. Our brands and products boast innovative features that make your work easier. When you buy GSI, you get an excellent product, backed by a strong warranty. We deliver valuable solutions and a personal commitment to every customer. GSI offers complete package solutions for all your grain storage and handling requirements. Our farm series bins range in size from 15′ to 60′ diameter with a variety of flooring, grain conditioning, and material handling options to choose from depending on your specific application.
Roof Panels: The new 40-Series™ roof panels incorporate a 3’’ tall rib with over-and-under lap profiles ensuring a precise fit (see illustration shown below). 3-bend rib profiles are also incorporated in the new design for increased strength to stand up even in the harshest environments.
Higher Capacity and Superior Protection: Each GSI bin is efficiently designed to handle maximum loads for unmatched strength. All GSI bins are constructed using the highest-strength steel available. Sidewall sheets are made from high-tensile steel that is rated up to 70,000 psi (450 MPa) minimum. A commercial G-90, galvanized steel coating increases life and durability.
Stiffeners: GSI’s stiffener profiles and the use of up to 2-gauge material make bins stronger, allowing 40-Series bins to go taller without the extensive use of lamination. Improved stiffener profile design is manufactured on precision roll-forming equipment for superior quality. Base stiffener boots are powder-coated so they won’t rust over time.
Wind Rings: Redesigned wind ring and wind ring brackets reduce bolt holes in stiffeners, resulting in increased load capacity. Swaged, bolted splice ensure your 40-Series bins will stand up to the toughest wind conditions.
JS500 Bolts: GSI uses JS500 bolts paired with sealing washers to protect the grain. In addition, JS500 coated hardware provides added protection from rust to ensure your grain bin stands the test of time.
Base Angle: Rolled structural base angle prevents water from entering at the base of the bin for improved protection.
Z-Tek™ Roof System: GSI’s 40-Series™ line of grain storage bins feature the precision-engineered Z-Tek™ Roof System. Designed for increased load capacity, the system incorporates z-shaped rafters and purlins, clips, peak ring, flat top and roof panel for unsurpassed strength and protection.
Roof Exhauster: Moving air in and out of the bin efficiently is essential. The 40-Series bin features new roof exhauster mounting plates near the peak for improved air flow by providing optimal separation of the intake vents and the exhausters. This allows for headspace air to be completely turned over and to minimize condensation on the bottom of the roof panels in colder climates.
Roof Vents: Redesigned roof vents promote increased airflow, meaning fewer vents are required. Vents feature a one-piece steel design with integrated cricket. Roof vents are available in grill vent and auto vent.
Increase Snow Load Capacity: You can rest assured knowing that your grain is protected and dry from the elements in a GSI grain bin. GSI 40-Series bins can handle even the harshest of winter seasons with increased snow load capacity.
Added Peak Load Capacity: The roll formed precision manufactured Z-Tek Roof System can handle up to 75,000 pounds of peak load. The extra capacity supports larger material handling equipment, allowing grain to move into storage faster than ever before.
Flat Top: With the increasing speed of harvest, the size and capacities of material handling equipment continue to increase, leading to the need for larger flat tops on which to land equipment. Integrated attachment points within the flat top eliminate guesswork on where to attach material handling equipment for more accurate assembly. An optional integrated peak walk-around is available on bins larger than 54’ diameter.
Purlins: All purlins are designed as compression purlins for even distribution of the roof load. The Z-Tek Roof System delivers an increase in peak and snow load capacities as well as a simplified design for faster installation. GSI purlins are manufactured using the latest roll-form technology to ensure the most accurate fit possible.
Roof Sheet Overlap: GSI’s in-plane roof lap is designed to stop leaking by eliminating the flashing that is required between the upper and lower panels. Single sheet roofs are standard for all bins up to 78’ diameter. From single-sheet roofs to an overlapped panel design, your crop is protected.
Temperature Cable Brackets: GSI’s Z-Tek Roof System temperature cable attachment brackets are standard for all bins 54’ and larger. Temperature cables can be used on bins 48’ and smaller with the optional addition of support brackets. The center collar includes an attachment point for the center cable so it’s ready to expand with you when you choose.
Dura-Lok Flooring: Easy to sweep and clean, Dura-Lok floor is the strongest floor available, making it ideal for tall bins. Supported by a post and beam system, the Dura-Lok floor features 3.5” wide sections for a more stable floor. A small grain option is also available.
Cut-Lok Flooring: An economical option, the Cut-Lok steel floor is efficiently designed with a 12% opening that prevents any restriction to air flow.
Sidewall Stairs: 2-piece step design – the strength of two steps in one. Step height designed for comfortable rise/step combination. Pre-rolled, 1.5″ round tube, smooth handrails. Optional inside handrail for increased safety and ease of climbing. Stairs can be wrapped clockwise or counterclockwise.
Platforms: Three options for platform placement with single or double platform options. High – located above the eave. Low – located below the eave. High/Low – combines a low platform in front of manway hole and a high platform to step onto roof (available on bins 60′ and smaller – 3 panel roofs only).
Roof Stairs: Roof stairs allow for a safe and easy transition from platform to roof. Comes in three sections to cover all roof combinations (3-step section, 4-step section, 8-step section) Designed to clear potential interference with roof rings and other objects.
Bin Ladders: GSI high-strength ladders have roll-formed sides and stamped rungs to eliminate rung spin. Quick assembly sections are available in 48” lengths and feature dimpled rungs for a better grip. GSI’s ladder cages are completely galvanized and bolt directly to the prepunched sidewall ladders. Also available are optional X-Series ladders, designed to meet OSHA specifications. Designed with step-through platforms, X-Series ladders are mounted 90 degrees to the sidewall to eliminate toe hazards such as stiffeners, wind rings and other bracketry.
Walk-Through Bin Doors: Walk-through doors are standard on all 40-Series™ grain bins. The outer door cover swings completely with the door cover hold-back and closes tightly with an exclusive weather seal, keeping water and pests out, and your protected grain in. All inner door panels on GSI’s walk-through door open completely. There are no horizontal bars or braces to unbolt or remove. To counteract friction set from grain loads, the specially designed lever latch multiplies the inner door opening force by 20 times, so opening is quick and easy. No wrenches or tools are required to operate.
