TRI-CORR® Bin Floor
The Brock TRI-CORR® Bin Floor increases the overall strength and offers three times more support at the floor’s crown compared to previous aeration floor designs.

• Features a unique, triangle-shaped center leg, reinforcing the center of the floor plank to help give the floor extraordinary strength and rigidity.
• Provides a flat floor plank for easier bin sweeping and grain clean-up operations.
• Designed so the plank and the floor support perform as a unit, standing up to the stresses of repeated loading and unloading.
• Handles normal operating loads imposed by most stirring devices.
• Floor planks nest together more tightly, making the floor plank bundles more stable and easier to handle during shipping and installation.

Innovative Floor Planks

• With its innovative, strength-giving, modified “M”-shaped profile, every Brock TRI-CORR® System floor plank measures 7 inches wide x 1-1/2 inches deep (178 x 38 mm).
• Brock’s exclusive TRI-CORR Floor profile adds a unique middle support leg to the floor plank to provide a third weight-bearing point. Other floors use only two. This ground-breaking design gives tremendous strength to Brock’s floor both for between supports and for transferring the weight load from the plank to the floor support.
• Planks are roll-formed from high-tensile, galvanized steel.
• To accommodate various sizes of grain, hole size options include openings that are .050 or .094 inches (1.3 or 2.4 mm) in diameter.

• Galvanized steel flashing at the bin sidewall is perforated to allow maximum airflow.
• At the sidewall, the flashing is formed to match the wall’s corrugation for a positive seal that also helps prevent grain loss.
