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 NCWT0108 is designed for use in 42'-60' (12.81 m-18.29 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 NCWT0108 (42'-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. A intermediate discha rge 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.
The external door frame stiffener will mount at the standard externally stiffened tank anchor bolt
location. (See Page 24.) If bolts have been pre-placed then place the frame and stiffeners over the
pre-placed bolts. If drill in anchors are to be used it is recommended the holes be pre-drilled at the
proper location.
4. The stiffeners are mounted in the frame directly under the tank stiffener columns. (See Page 25.)
For the case of the externally stiffened tank these stiffeners will be mounted in the external frame.
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 stiffeners will mount in the frame such that t he tank stiffener will bear directly above
it. Should the stiffeners not be so placed, they should be placed in that location. Standard base
stiffener weldments mount above the frame stiffeners.
5. Left and right hand jamb plates (NCWT0091L and NCWT0091R) 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 (S-3885) for the plate to jamb
connection utilize 7/16" x 2" bolt for stiffener to jamb to plate 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.
At the stiffener to frame to plate connection install the bolts with the head and sealing wa sher on the
inside 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.
Shim as necessary with 7/16" flat washers to obtain proper alignment with door panel hinges.
(See Page 27.)
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 thickness.
Bolt head/sealing washer should be on the outside of the tanks for this connection.
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.

5. Assembly Instructions
Written instructions for installation of a NCWT0108 (42'-60' diameter bin/silo) 2 ring door pa ckage
in a externally stiffened tank. (Continued)
The horizontal seam of the sidewall sheet above the door header will bolt to the jamb plate 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 frame stiffener. Shim as necessary for firm
support and bolt the stiffeners together using a 3/4" x 5" bolt, 3/4" nut and 3/4" washer.
7. Bearing pins, WD-6224 (8), are mounted to the inside frame flange at the eight (8) large/0.65" x 0.75"
slots. Use S-2741, 5/16" x 1-1/2" bolts and attach the bearing pins at these eight (8) locations by
inserting the grooved pin into the hole and running the 5/16" bolt to the inside. (See Page 21.)
Use 5/16" washer (S-845) and 5/16" flange head 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 as shown in Pages 19and 20. 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. Be sure door panels open smoo thly and the
latch bars lock completely. Apply 1/2" x 1" seal strip to the inner frame weldment to seal around the
inner panels.
9. Bolt the outer cover attachment angles onto the outer frame weldment with 5/16" x 1-1/4" bolts.
Use a 5/16" flat washer on all slotted connections. Refer to Page 18 for details.
10. Attach the outer cover hinge weldment (NCWT0165) and the latch brackets (NCWT0166) to the outer
cover angles with 5/16" x 1-1/4" bolts. Bolt head should be on the inside for all outer cover angle
connections. Use a 5/16" flat washer on all slotted connections. Refer to Page 18 for details.
11. Assemble the exterior cover as shown in
hinges (NCWT0170) and reinforcement channels to the outer cover as shown. Use 5/16" x 3/4" bolts
for all outer cover reinforcement channel connections only. Use 5/16" x 1-1/4" bolts for all retaining
bracket and hinge connections. The bolt head with sealing washer should be on the outside of
the door cover for these connections. Attach the outer cover assembly to the outer cover hinge
weldments with 3/8" x 4-1/2" bolts and nuts. Adjust hinges until outer cover opens and closes
smoothly. Apply 1/2" x 1" foam seal strip to the outer frame weldment to seal outer cover. Fill all
un-used bolt holes with 3/8" x 1" bin bolts. Check to ensure that the unloading decals (DC-GBC-2A
and DC-GBC-2S) are installed on the outside of the outer door cover. Check to ensure tha t the
danger decals (DC-GBC-1A and DC-GBC-1S) are installed on the inside of the outer door cover.
