Grain Bin Floors – Durable, Aerated Flooring Solutions by Brock and Sioux Steel
A high-quality grain bin floor is essential to the long-term success of your grain storage system. Whether you’re building a new bin or upgrading an existing one, choosing the right floor ensures better aeration, structural support, and protection from moisture-related spoilage. Our selection of grain bin floors, including top-tier models from Brock and Sioux Steel, is engineered for durability, efficient air distribution, and lasting performance in both farm and commercial grain storage environments.
Engineered for Strength and Airflow
The primary purpose of a grain bin floor is to provide structural stability while enabling uniform airflow throughout the grain mass. Proper airflow prevents hot spots, mold growth, and insect infestations—three major threats to grain quality during storage.
Both Brock grain bin floors and Sioux grain bin floors are designed with this principle in mind. These perforated floors allow air to pass through evenly, promoting consistent drying and conditioning of grain. Brock’s patented LeMar® floor systems and Sioux’s Free-Flow™ floors are crafted with high airflow capacity and structural efficiency, making them ideal for bins of all sizes and storage capacities.
Heavy-Duty Construction
Built from galvanized steel, our grain bin floors offer maximum corrosion resistance and long-term durability. These floors are designed to withstand the weight of stored grain, unload equipment, and foot traffic. Sioux Steel’s floors, in particular, emphasize equal air pressure distribution and high strength per square foot—critical for maintaining structural integrity over time.
Sioux’s Free-Flow floor supports are engineered to reduce obstruction to airflow while offering superior strength. These supports are compatible with a variety of floor styles, including plank and flat corrugated flooring. The Flat Top Model is especially popular for ease of installation and its ability to handle heavy loads.
Similarly, Brock’s grain bin floors use a combination of deep rib designs and robust supports to ensure long-lasting strength while promoting airflow efficiency. Their systems are engineered for fast, trouble-free installation and are compatible with Brock’s advanced grain handling equipment.
Easy Installation & Versatility
Whether you’re installing a complete grain bin floor system or replacing individual components, our floors are designed with installation efficiency in mind. Pre-cut panels, modular support structures, and precision engineering ensure each floor section fits securely and evenly. That means less downtime during setup and better performance once the bin is in operation.
Our floor systems are available in a wide range of sizes, making them suitable for grain bins from 18’ to 60’ in diameter or more. Whether you’re working with a Brock or Sioux bin—or retrofitting another brand—our grain bin floors are built to integrate seamlessly.
Moisture & Spoilage Prevention
One of the most important features of a quality grain bin aeration floor is its ability to keep grain dry and well-ventilated. Moisture buildup at the bottom of a bin can lead to crusting, clumping, and costly spoilage. Our floor systems prevent this with optimized air distribution and corrosion-resistant materials that hold up in high-humidity environments.
When paired with the right aeration system—such as grain bin fans and heaters—these floors become the foundation of a complete grain conditioning solution. Sioux and Brock floors work flawlessly with their respective aeration components to keep your grain in peak condition all year long.
