Introducing a Better Bin

EVO 50 Grain Bins

Take Control with Better Protection

You can’t afford post-harvest loss. That’s why the EVO 50 grain bin is engineered to keep the elements outside. So, you can earn more from what’s inside.

We’ve maximized strength at each connection and needed fewer bolts to do it. Water has less chance to get in. Our advanced sealing system keeps it out. Larger capacity equals even better protection with 50% fewer vertical seams.

Built to Perform

EVO 50 Bolt Pattern

Durability

Bolt Pattern

EVO 50 bins feature an optimized bolt pattern for fewer bolts and fewer holes. Hardware is even more durable with 4X corrosoin protection, and includes an advanced sealing system for a water-tight seal.

Interlaced Sheets

Strength

Interlaced Sheets

Interlaced laminated sheets maximize strength and keep water out.

Available on bin diameters 66' (20.12 m) and larger.

Double Length Sidewall Sheets

Innovation

Double Length Sidewall Sheets

Double length sidewall sheets reduce vertical seams and number of bolts by up 50%.

Available on bin diameters 90' (27.43 m) and larger.
