Gateway Building System’s Flex-N-Seal offers a better way to seal the base of your new or existing grain bin.

Flex-N-Seal is the easy, effective, and economical answer to the challenge of keeping grain safe from moisture leaks. Flex-N-Seal replaces messy tar with formulated acrylic latex reinforced with nylon fiber mesh. Its waterproof protection reflects moisture and it doesn’t crack. The cured seal moves with the contour of the bin – expanding to 300%. In addition to sealing cracks and bin bases, Flex-N-Seal can be used on take-out tubes, aeration ducts, bin doors and all types of farm structures including Quonsets and Pole Barns. Whether your bin is empty or full, it’s easy to apply. For over 30 years, farmers have been looking to Gateway Building Systems for storage solutions. We’ve made a commitment to our customers to continually offer services and products like Flex-N-Seal that add security and profit to their bottom line.

Grain Handling

We can help with Air Systems, Augers, Conveyers, Distributors, Scales and other grain handling accessories.

Move your grain from your truck to your farm or commercial farm site quickly and efficiently during harvest with our top-quality dump pits.  Available is sizes from 50 bushels to 1,200 bushels.

Dump pit sites are crucial in farming operations and are worth the investment for several reasons:

1) Time Efficiency:

  • Dump pits allow for quick unloading of harvested grain directly from the combine or truck, significantly reducing waiting times.
  • Time saved in unloading contributes to streamlined harvesting operations, enabling farmers to capitalize on optimal weather conditions.

2) Continuous Harvesting:

  • With dump pit sites strategically located, farmers can maintain a continuous flow of harvesting, minimizing downtime during peak seasons.
  • Efficient unloading ensures that equipment remains in the field, maximizing productivity and yield.

3) Reduced Labor Costs:

  • Automated dump pits minimize the need for manual labor in the unloading process, reducing associated labor costs.
  • This allows farmers to allocate resources more efficiently and focus on other critical aspects of farming operations.

4) Enhanced Safety:

  • Dump pit sites are designed for safe and efficient unloading, reducing the risk of accidents associated with manual unloading or crowded storage areas.
  • Automated systems ensure a controlled and secure unloading process, promoting a safer working environment.

5) Increased Storage Capacity:

  • Dump pits facilitate the quick transfer of grain from the field to storage facilities, ensuring optimal use of storage capacity during peak harvest periods.
  • This enables farmers to manage large harvests effectively without the need for additional temporary storage.
6) Optimized Logistics:

  • Strategic placement of dump pit sites allows for efficient logistics planning, minimizing transportation bottlenecks and optimizing the movement of harvested grain.
  • This results in a smoother flow of grain from the field to storage or transportation to market.

7) Improved Grain Quality:

  • Quick unloading reduces the likelihood of grain damage or deterioration, ensuring that the harvested crop maintains its quality.
  • Preserving grain quality is essential for obtaining better prices in the market and maintaining overall profitability.

8) Adaptability and Scalability:

  • Dump pit sites can be designed to accommodate the specific needs and scale of a farming operation.
  • Farmers can invest in dump pit systems that align with their current needs and easily scale up as their operations expand

An Air system is an efficient way to move your grain on your farm. The grain is moved through the tubes using high pressure air, which allows grain-handling convenience and installation ease.

Get the most out of your dollar when moving grain.  Augers are a good alternative for budget installations

Bucket Elevators (also known as Grain Legs) offer multiple capacities to maximize your efficiency.  Grain legs handle material with very little damage and are extremely low maintenance.

If you are looking to move your grain a long distance, a Belt Conveyor’s adaptability allows for it to be utilized in a horizontal and/or inclined segment – perfect for your commercial facility.

Drag chain conveyors are built to get the job done.  Chain conveyors are a long lasting, low maintenance solution for moving grain.

Grain Pump style tube conveyors may be a good alternative to the traditional auger or air system.  We’ll work with you to determine which type of conveyors best fit for needs and budget.

Effectively distribute your grain to multiple spouts with a distributor.  Manually or electrically operated distributors by Schlagel and other manufacturers minimize problems and maximize ease.

Conveniently weigh your truckloads on-site.

Spouting, elbows, clamps, flanges and adjustable spout ends are available.

Grain Management Systems

Let us help you design and build a customized Grain Management System to improve your operation.

The Industry’s Leading Grain Bin Management Solution.

You invest too much in your crop to run the risk of shrinkage or over-drying in your grain bins.

IntelliFarms’ premier product, BinManager, dries, cools and even re-hydrates grain to your targets with precision. Using our patented 3G Plus™ Cables, BinManager measures the moisture and temperature throughout the grain mass and analyzes this data against the conditions of the outside air and the air in the plenum. From there, it determines and automates when the fans and/or heaters run.

You can easily track your BinManager’s progress by logging into your IntelliFarms Portal account, where you receive hourly updates on the moisture and temperature status of your grain and BinManager current status. No more manual probing or climbing the bins – you can check your BinManager activity from your Smartphone, tablet or computer anytime from anywhere.


Control the temperature of your grain all-year-long.
