Introducing a Better Bin

EVO 2X Bin Sheets

EVO 2X Grain Bins

We've attacked the weakest points to give you a stronger bin

We call it addition by subtraction. We eliminated half the vertical seams by doubling the length of each sheet. And we maximized strength at every connection with 50% fewer bolts. It all adds up to better protection.

EVO 2X Bins are available in 90' (27.43 m) diameter and above.

EVO 50 Grain Bins

Take Control with Better Protection

You can’t afford post-harvest loss. That’s why the EVO 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.
