Bin Floors & Supports are designed to accommodate most drying or storage needs. Sukup Channel-Lok™ floor planks feature sturdy J-shaped, interlocking sides. Each plank is made of high-strength, galvanized steel and is cut to length with computerized accuracy. Sukup Heavy-Duty Perforated floors and SuperWave® Supports install easily over concrete tunnels for an efficient, low-cost aeration alternative.

Sukup manufactures Heavy-Duty Perforated, Hawk Cut®, and Channel-Lok™ Perforated bin floors. These bin floors are engineered for airflow and durability. They feature a design that promotes proper air circulation throughout the grain, a key factor in preventing spoilage and maintaining grain quality. The construction of these floors provides a stable and strong foundation for grain storage, supporting heavy loads while allowing airflow.

Sukup’s supports are built to enhance the strength and stability of the storage system. Sukup offers SuperWave® Supports, Z-Post, Super Supports™, and Flat Top Super Supports™. Sukup Superwave® Supports are one of the strongest supports on the market and work with all Sukup floor types. They feature a unique wave design that creates more surface area to support the floor planks, while simultaneously making the support more stable than other sheet metal supports. Super Supports™ and Flat Top Super Supports™ are typically recommended for drying bins. Sukup Super Supports™ can be used with most Sukup bin floors and provides excellent airflow, easy installation, and an extra strong design. Flat Top Super Supports™ are designed for use with Heavy-Duty Perforated floors. For details on compatible Sukup bin floors and supports, please visit the Bin Floors Brochure.

Together, Sukup’s Bin Floors & Supports provide a stable, durable, and well-aerated environment for stored grain. Sukup’s commitment to quality and innovation is represented in these products, making them a trusted choice for producers looking for reliable grain handling and storage solutions.
