The Behlen Grain Systems stiffened series bins feature broad roof decks engineered for superior strength, durability, and long-term performance. Designed with large-diameter openings and multiple peak load options, these grain bin roof systems can be configured to meet a wide range of operational and customer requirements.

Built for demanding agricultural and commercial grain storage applications, the stiffened roof design provides enhanced structural support while allowing flexibility for conveyors, catwalks, and additional roof-mounted equipment.

Roof Designed With Unique Structural Features

Behlen Grain Systems roof panels are engineered with rigidized construction between extra-tall 3-1/2" high ribs to deliver increased strength, stability, and long-term durability. Each panel is securely fastened at the eave using a continuous angle iron and reinforced rib brackets, providing enhanced resistance against high winds and harsh weather conditions.

Designed for dependable agricultural and commercial grain storage applications, this reinforced roof system improves structural performance, protects stored grain, and supports long-lasting operation.

Uniquely Designed Wall Systems

Sturdy, Long-Lasting Wall System

Behlen Grain Systems bins feature a flat-sided (trapezoidal) wall configuration engineered with built-in wind bands as a standard feature on inside-stiffened bins. This innovative wall system provides superior strength and rigidity to help resist side draw pressure and high wind loads commonly experienced in demanding grain storage environments.

The integrated design eliminates the need for additional bolt-on wind pipes, creating a cleaner, more durable structure with fewer external components. Built for long-term performance, Behlen’s wall systems deliver reliable support and enhanced structural integrity for agricultural and commercial grain storage applications.

Superior Panel Strength

Behlen Grain Systems bins are engineered for superior panel strength and long-term durability. The vertical seam lines feature a large overlap design with four or five rows of bolts, creating a strong, secure connection between panels for added structural integrity.

Combined with a rigid anchor bracket system and roll-formed base angle, this reinforced construction helps withstand the pressures of stored grain while maintaining stability and performance over time. Designed for dependable agricultural and commercial grain storage, Behlen bins keep your grain secure, protected, and ready for market.

Stiffeners With Exceptional Load-Carrying Capabilities

Behlen Grain Systems bins are built with heavy-duty, hat-shaped stiffeners engineered to provide superior resistance to grain loads and demanding storage conditions. Each stiffener is manufactured from a single piece of steel up to 5/16" thick, delivering outstanding strength and durability without the need for laminated stiffener materials.

Designed for maximum structural performance, each stiffener supports the next through an integrated load-bearing plate system that ensures positive load transfer directly into the concrete foundation. This reinforced design enhances overall bin stability while improving long-term reliability in commercial and agricultural grain storage applications.

These heavy-duty, stiffeners also allow Behlen bins to be cleaned using a single-pass sweep without additional reinforcement, improving operational efficiency and reducing maintenance demands.

Standard Crawl Door

The Behlen Grain Systems stiffened series bins come standard with a durable 27" square single-ring crawl door designed for convenient bin access and dependable performance. Engineered for strength and ease of operation, the crawl door provides safe entry for inspection, maintenance, and cleanout procedures in agricultural and commercial grain storage applications.

Optional Walk-Through Door

The optional two-ring walk-through door provides convenient, easy access to the bin interior for maintenance, inspections, and cleanout operations. Designed for improved accessibility, the system includes both inner and outer doors with an opening measuring more than 2 feet wide and over 5 feet high.

Built for durability and ease of use, this optional feature enhances efficiency while supporting safe access in agricultural and commercial grain storage applications.

Gooseneck Roof Vent

Behlen Grain Systems gooseneck roof vents are engineered for efficient airflow, dependable ventilation, and fast installation in grain storage applications. Each vent features a 1.56 sq. ft. opening and is designed to fit pre-punched roof openings, streamlining assembly and reducing installation time.

Built for durability and long-term performance, these roof vents promote proper air circulation while supporting moisture control and preserving grain quality. Ideal for agricultural and commercial grain storage systems, the rugged gooseneck design also provides reliable weather resistance in demanding operating environments.

Pre-Punched Roof Vent Opening

Behlen Grain Systems roof panels feature pre-punched roof vent openings designed for faster installation and improved weather protection. Each opening is engineered with a raised lip that helps reduce moisture intrusion and enhance long-term durability and ventilation performance.

This integrated feature streamlines roof vent assembly and supports reliable airflow in agricultural and commercial grain storage applications, helping maintain proper grain conditions and protect stored commodities from the elements.

Low Profile Roof Vent

Behlen Grain Systems' exclusive low-profile roof vents are engineered to sit close to the roof panel, helping reduce exposure to high winds and minimizing the potential for wind damage. Their streamlined design makes them an excellent choice for port facilities, coastal regions, and other high-wind environments.

Available with 3.13 sq. ft. openings, these heavy-duty roof vents provide efficient airflow while reducing the total number of vents required for the grain bin roof system. Designed for long-lasting durability and dependable ventilation, they are ideal for agricultural and commercial grain storage applications that require reliable air circulation and weather resistance.

STIFFENER EXTENSIONS

Stiffener extensions are offered to transfer loads from the base of the stiffener columns to the bottom of customer installed aeration tunnels. Available in heights of 12¼”, 11¾, and 7¾”.

SAFETY RAIL AND ROOF STAIRS

Optional peak safety rail encloses the flat peak area for added safety protection. The Behlen hot-dipped galvanized roof stairs come in pre-assembled sections. The mounting brackets and handrails are easilty attached.
