EVO 2X™ Grain Bin

Fewer Leak Paths. Better Protection.

HIGHLIGHTS

Double-length sidewall sheets reduce vertical seams by 50%.
Fewer seams mean fewer connections and fewer potential leak paths.
Simplified construction for faster, more consistent builds.
Designed for 90’ diameter bins and above.

Introducing a Better Bin

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. EVO 2X Bins include an advanced sealing conical washer for a water-tight seal.

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.

Fewer Seams. Better PRotection.

Double-length Sidewall Sheets

The sidewall sheets on a GSI EVO 2X bins are twice the length of standard bin sheets, cutting the number of vertical seams in half. Fewer vertical seams, means fewer bolts. The result is better protection against water intrusion and faster erection.

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.
