40-Series Grain Bin

THE NEXT GENERATION IN GRAIN STORAGE...
FOR NEXT GENERATION YIELD TECHNOLOGY.


Why Choose 40-Series™ Grain Storage?

Higher Capacities
Whether it is for food, feed, or fuel, we need to move grain more efficiently than ever. GSI’s new Z-Tek™ Roof System, with its large flat top and higher peak loads, supports larger material handling equipment, allowing more grain to move into storage faster than ever before.

The design of GSI’s new stiffener profile increases strength, allowing you to go taller with your grain storage system and have more flexibility in design.

Superior Protection
With rising commodity prices, it is critical to protect this high value inventory and optimize its condition. Flashing-free roof overlaps, increased snow load capacities, and polyethylene sealing washers all provide superior protection of your grain from the elements.

A Complete Family of Accessories
Taking care of your grain takes an entire system, and GSI offers a complete family of grain bin accessories that make working in and around your storage system an easy and safe experience.


Z-Tek Roof
Z-Tek Roof

The Evolution of Bin Roof Design
GSI’s 40-Series™ line of grain storage bins feature the revolutionary Z-Tek™ Roof System. The Z-Tek roof is designed to increase load capacity and allow for larger fill equipment. Working as a team, the precision engineered Z-Tek Roof System incorporates z-shaped rafters and purlins, clips, peak ring, flat top, and roof panel for unmatched strength and protection.

Z-Shaped Design
The Z-Tek Roof System features a z-shaped design, which maximizes strength by minimizing rotational torsion. Z-Shaped rafters and purlins accomplish more with less.

Purlins

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 for a precise fit.

Flat Top

Flat Top
With the increasing speed of harvest, the size and capacities of material handling equipment have increased, leading to the need for larger flat tops on which to land equipment. Integrated attachment points within the flat top eliminate guess work on where to attach material handling equipment for more accurate assembly. An optional integrated peak walk-around is available on bins larger than 72’ diameter.

Roof Connections

Roof Connections
With common hardware sizes used on all connection points, roof construction is easier. Double clip attachment at peak ring makes for a stronger connection between ring and rafters. A continuous eave attachment provides simplified connection of roof panels to sidewall for better protection of your grain.

Extensively Tested
Testing with loads totaling over 225,000 lbs. The Z-Tek Roof System is designed to handle extreme loads.


Stiffeners

Stiffeners
GSI’s new stiffener profile and use of up to 2-gauge material, leads to an increase in strength, 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 over galvanized for improved corrosion resistance.


Wind Rings

Wind Ring
Redesigned wind ring and wind ring brackets reduce bolt holes in stiffeners, resulting in increased load capacity.

New splice system increases strength.


Temp Cable Brackets

Temp Cable Brackets
GSI’s Z-Tek™ Roof System includes standard temp cable attachment brackets, eliminating the need to order additional parts.

The center collar includes an attachment point for the center cable.


Base Angle
Rolled structural base angle prevents water from entering at the base of the bin for improved protection.


JS500 Bolts
To give the most protection to the grain and ensure our grain bins stand the test of time, GSI uses JS500 coated hardware for added protection from rust. JS500 coated hardware is 5 times more resistant to red rust than standard zinc hardware.


Roof Lap

Roof Sheet Overlap
GSI’s in-plane roof lap minimizes the chance for leaks by eliminating the amount of flashing required between upper and lower panels.


Roof Vent

Roof Vents
GSI offers two styles of roof vents to fit your particular requirements. The hinged grill vent features a vertically mounted, large mesh, wire formed screen to keep out pests, and it swings open freely to allow release of trash buildup. The Auto-Vent is a revolutionary concept in vent design, reducing “plugging”.


Roof Exhausters
The 40-Series bin features new roof exhauster mounting plates near the peak for improved airflow.


Door

Ground Level Entry Options
A standard 24” diameter door is located in the second ring of GSI commercial tanks up to 105’ diameter. Optional two ring doors (standard on 135’) feature a strong frame and an easy opening two piece inner panel. GSI also offers an optional vehicle traffic door for use where a skid-steer loader will be used for final clean out or a larger opening is required.


Flooring

Custom Floor Designs
Many aeration floor systems are available from full floors above concrete with custom plenum heights, to various flush floor in-concrete patterns.  MORE


Fans
GSI manufactures a complete line of aeration and grain conditioning systems including centrifugal, inline centrifugal, and vane axial.  MORE


Stairs, Safety Cages, Platforms and Ladders
GSI offers both ladders and stairs as outside climbing options. Stairs offer a shallow 8” step that decreases the incline angle for an easier, safer, and more comfortable climb. Ladders offer easy access and are made from roll-formed side rails with press fit dimpled rungs. Cages bolt directly to the sidewall ladders and the bottom of the cage has a bell section which allows ample space while climbing.

X-Series Stairs

X-Series Ladders, Stairs and Platforms
X-Series stairs feature powder-coated roll-formed handrails, large tread plate with extruded slip-resistant pattern, and fully galvanized steps. Ladders have step through platforms and are mounted 90 degrees to the sidewall to eliminate toe hazards such as stiffeners, wind rings, and other bracketry. X-Series ladder and stair packages are designed to meet OSHA specifications.
