TopDry
Sidewall and Roofs
TopDry utilizes strong vertical stiffener columns to cary the vertical
load of the bin and system to the foundation. Stiffeners are manufactured
from high strength 65,000 PSI (450 MSA) steel. The stiffeners are
mounted on the outside of the tank to allow for unimpeded grain
flow inside and feature strong splice joints and a large cross sectional
area.

Top Dry Specifications
Heavy Base
Plates
TopDry
stiffeners are fitted with heavy base plates which bolt directly
to the concrete. These plates give the stiffeners a larger load
bearing area to transfer the load to the foundation and andhor the
bin securely.
Optional
full circle roof rings are available for additional
convenience when working on or inspecting the tank roof.

High Tensile
Sidewall
The
4" wide corrugated sidewall design is standard on the GSI Top
Dry system. The 44" tall sheets are constructed using 65,000
PSI minimum, high tensile steel for a strength and solid support.
All sidewalls feature G-90 bright spangle galvanized coating to
ensure a long tank life. GSI also uses graded, zinc plated, high
strength, dichromate bolts at all connections. Each bolt has a special
sealing washer to keep out the elements. Bolts with polypropylene
coated heads are also available as an option.

Top Dry
Roof System
Just
as with the corrugated sidewall sheets, GSI fabricates Top Dry roofs
out of prime, high tensile, G-90 galvanized steel. Each roof rib
is roll formed with triple ridged rib sides for strength. In addition,
a shallow corrugation in the flat area between roof ribs is added
for increased rigidity.
Roof ribs are fully double lapped to help keep the weather on the
outside of the bin.

Roof Vents
GSI
offers two unique vents to meet your ventilation requirements. The
hinged grill vent features a vertically mounted, large mesh, wire
formed screen to keep out pests and swings freely open to allow
easy release of trash buildup. The Auto-Vent is designed to reduce
"plugging" or air restriction through the use of a special
wing-shaped damper. When fans are running, air passes freely above
and below this damper allowing it to float open in mid air. The
damper drops down and closes when the fan is not in operation to
help block out wind, snow, birds, etc. from entering. Both vents
are assembled with a heavy duty locked seam and for additional protection,
a die-cut gasket is placed between the vent and roof panel to further
decrease water penetration.
GSI provides roof panels with an exclusive factory-prepunched, extruded
lip for each vent.
