EVO 50™ Grain Bins

Better Protection. Built to Last.

HIGHLIGHTS

4″ corrugation.
Optimized bolt pattern.
Heavy-duty, symmetrical stiffeners for uniform strength and consistent load distribution.
Powder-coated stiffener boots provide added corrosion protection and long-lasting performance.

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.

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.

Built to Perform

Stronger Connections

STaggered Bolt Pattern

EVO Grain Bins feature a staggered bolt pattern, which increases the space between bolts and reduces the number of holes in the sidewall. That spacing better distributes load through the bin wall.

Increased Shear Strength

GSI Interlaced Lamination

GSI’s interlaced laminated sheets maximize strength by distributing load across five shear planes. This improved structural performance is achieved through smarter design, rather than additional parts.

Traditional lamination places all load across one shear point. The splice plate lamination, used by some competition, places load across two shear planes but use additional parts and more bolts.

Interlaced lamination is available on GSI bin diameters 66′ (20.12 m) and larger.

Superior Protection

Sidewall Sheets

Each GSI bin is efficiently designed to handle maximum loads for unmatched strength. Sidewall sheets are manufactured from high-tensile steel that is rated at up to 70,000 psi.

Precision Engineered

Z-Tek™ Roof System

The precision-engineered Z-Tek™ Roof System is designed for increased load capacity, the system incorporates z-shaped rafters and purlins, clips, peak ring, flat top, and roof panel for unsurpassed strength and protection.

Available on bins 36’ (10.97 m) and larger.
