2. Safety
Proper Storage of Grain Bin/Silo Materials Prior to Construction
Wet storage stain (rust) will develop when closely packed bundles of galvanized material, such as sidewall
and roof sheets, have moisture present. Inspect roof and sidewall bundles on arrival for any moisture. If
moisture is present, it must not be allowed to remain between the she ets. Separate the sheets or panels
immediately and wipe them down. Spray with a light oil or diesel fuel.
If possible, sidewall bundles, roof sheets and other closely packed galvanized materials should be stored
in a dry, climate controlled building. If outdoor storage is unavoidable, the materials should be stored so
that they are raised above the ground and vegetation. Any stacking an d spacing mat erials sho uld not be
corrosive or wet. Be sure to protect materials from the weather, but permit air movement around the
bundles if possible.
Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of
moisture. Storing the bundles with the center of the dome up (like an arch) is one option for minimizing
moisture during storage. Sidewall bundles can also be stored on edge but must be secured so that they
do not fall over and cause injury.
If “white rust” or “wet storage stain” occurs, contact the manufacturer imme diately about ways to minimize
the adverse effect upon the galvanized coating.

4. Important Note
This GSI commercial 2 ring door is designed for use in the 2.66" corrugation NCL series of tanks
manufactured after 1991 utilizing the “universal” or hat shaped stiffener. This door is intended for use with
a tank specifically structured for the installation of the 2 ring door. Special sidewall sheets are provided
as part the tank sidewall bundles. You must consult with GSI concerning retrofitting into any existing
GSI manufactured tank.
The door package NCWT0084 is designed for use in 72'-90' (21.95 m - 27.43 m) diameter tanks with a
maximum eave height = 90'-10"/27.69 meters and external stiffeners.
You should not attempt to install this door in any 2.66" corrugation GSI “Z” stiffener tank (pre 1991 series).
This door should not be installed in any GSI 4.00" corrugation series tank.
Consult with GSI concerning retrofitting into any existing GSI manufactured tank to determine compatibility
of the door package with the existing sidewall and stiffener configuration.
This door should not be installed in any tank not manufactured by GSI.

5. Assembly Instructions
Written instructions for installation of a NCWT0215 (54'-60' diameter bin/silo) 2 ring door package
in a externally stiffened tank.
1. The commercial 2 ring door is installed in the bottom 2 rings.
2. The door should normally be placed in line with the conveyor. An intermediate discharge well should
be located near the wall to clear grain from the area of the access door (as with any access door).
The door must be positioned directly below the vertical seam as shown in Figure 6A on Page 17.
3. The door has an inside frame weldment and an external frame weldment/assembly. If the tank has
not been erected the internal frame weldment should be placed inside the tank before erection. If the
tank has been erected or erection has begun, it will be necessary to remove sidewall and stiffeners
in the door placement area to place the inside frame weldment.
4. The door frame stiffeners are mounted in the external door frame directly under the sidewall stiffener
columns. (See Page 25.) The frame should have the stiffeners already in place with two (2) bolts to
hold them in location. These bolts will need to be removed to install the door, however the stiffeners
may be left in position in the frame.
The external door frame stiffener will be located in the standard externally stiffened tank anchor bolt
location. (See Page 24.) Anchor bolts should not be placed in this location. If these anchor bolts are
pre-installed, they will need to be cut off. After all final adjustments to the door have been made, the
anchor bolts should be drilled in place through the internal frame. (See Page 24.) GSI re commends
Hilti 1" x 12" H.A.S. threaded anchor and 1" x 8-1/4" H.V. U. adhesive capsules. (For seismic or
special situation tanks, consult GSI Engineering.) The external door frame stiffener must be field
welded to secure it to the frame. (See Page 24.)
5. Left and right hand jamb plates (NCWT0216L and NCWT0216R) are provided for attachment of the
sidewall sheets to the door frame. The jamb plate will mount between the internal an d external frame.
Place the jamb plate between the internal and external frame and bolt the frame, plate and stiffener
together utilizing 7/16" diameter bolts. Utilize 7/16" x 1-1/2" bolts for the plate to jamb connection
utilize 7/16" x 2" bolt for jamb to plate to hinge connection. (See Page 26.) At the jamb plate to frame
connection install the bolts with the head and sealing washer on the outside of the tank. The internal
door panel hinges will mount utilizing stiffener to frame bolts (on the inside of the tank). Place an
additional sealing washer under the hinge at those bolt locations before bolting it in place. Place
hinges as shown on Page 27. The external door cover hinges will mount inside the stiffener on the
outside of the tank.
6. The sidewall sheets to the left and right of the door will mount to the outside of the jamb plate.
Two (2) special short sidewall sheets (44") and two (2) standard length (119"), special punched
sheets are provided. Attach the sidewall to the jamb plate utilizing 3/8" diameter x 1-1/2" long bolts.
(See Page 26.) Corrugated sealing strip, CWT-0053 is provided. This may be mounted at the o uter
edge and inner edge of the jamb plate to sidewall interface. Caulk around the seal strip as well. A
flat washer may be required under the nut for certain gauge thicknesses.
NOTE: For tanks that utilize 13 gauge or thinner material 3/8" x 1" bolts may be used to attach the
sidewall to the jamb plate.
The horizontal seam of the sidewall sheet above the door header will bolt to the jamb plat e where it
extends above the door frame. The sidewall will be on the exterior of the plate. Install base angle
(B-6753) at the area the plate does not extend above. Utilize silicon caulk as necessary to seal
this location.
Standard base stiffeners will mount directly above the external door frame stiffener. Shim as
necessary for firm support and bolt the stiffeners together using a 3/4" bolt and washer.

in a externally stiffened tank. (Continued)
7. Bearing pins, WD-6224 (8), are mounted to the inside frame flange at the 8 large/0.65" x 0.75"
slots. Use 5/16" x 1-1/2" bin bolts (S-2741) and attach the pin to these eight (8) locations. Insert the
grooved pin into the slot with the bolt head to the inside. (See Page 21.) Use 5/16" flat washer
(S-845) and 5/16" flange nut (S-3611) to secure bearing pin.
8. Assemble the door handle reinforcement angles, door handles, latches and hinges to the top and
bottom inner door panels on Pages 19 and20. Install the 1/2" x 1-1/2" bolts in the outer door frame
at four (4) locations and thread the door latch bar holder (WD-6234) onto the bolt. The door handle
will mount over these holders when installed. Utilize washers if necessary to adjust the latch bar
holder position. (See Page 21.) Mount the door panel onto the four (4) bearing pins and lock the
latches over the latch bar holder. Center the bearing pins in the door panel holes and tighten.
Then, attach the door panel hinges to the frame hinges. Adjust the door panels until they open and
