3.1. Bin Design and Capacity
These Westeel Grain Bins are designed for:
1. Non-corrosive free-flowing materials up to 55 lbs/ft3(880 kg/m3) average compacted bulk density.
2. Maximum horizontal gusted wind speed of 94 mph (151 km/h)
3. Seismic zone 2a (U.B.C. 1997).
4. Roof Loading
Snow Load Peak Load
15’ — 24’ bins 27’ — 48’ bins
Imperial Metric Imperial Metric Imperial Metric
15.0 lbs/ft2.72 kPa
4000 lbs. 17.8 kN 5000 lbs. 22.2 kN
24.0 lbs/ft2
(when optional roof
stiffening rings
installed)
1.15 kPa
(when optional roof
stiffening rings
installed)
3.2. Foundation Design and Loads
The foundations for the stiffened bin models are based on 4000 lbs. per sq. ft. (192 kPa) soil bearing capacity.
All foundation designs use 3000 lbs. per sq. in. (21 MPa) ultimate compressive strength (after 28 days) for
concrete and 43,500 lbs. per sq. in. (300 MPa) re-bar. The foundation designs included in this manual are
suggestions only, and will vary according to local soil conditions. Westeel will not assume any liability for results
arising from their use.
Important
Foundation should be uniform and level. Level should not vary by more than ¼" over a span of four feet
under the bottom ring angle. Any variance from level must be shimmed under upright base assembly. If
being utilized to support a full floor aeration system, this levelness requirement should extend across
the complete floor area.
3.3. Site and Assembly
Unless otherwise specifically provided in writing, Westeel does not take responsibility for any defects or
damages to any property, or injury to any persons, arising from or related to any site or assembly
considerations, including but not limited to:
• Bin location and bin siting
• Soil conditions and corresponding foundation requirements (note that the examples provided in manuals
are for specifically stated soil conditions)
• Bin assembly (Westeel recommends the use of qualified bin installers; contact Westeel for information on
installers in your area)
• Field modifications or equipment additions that affect the bin structure
• Interconnections with neighboring structures
3. BEFORE YOU BEGIN CEW SEALFORM – WIDE-CORR® GRAIN BIN

194543 R8 11
• Compliance with all applicable safety standards, including but not limited to fall restraint systems (ladders or
other systems). Local safety authorities should be contacted as standards vary between jurisdictions.
3.4. Methods of Installation
The recommendations for assembling and installing Westeel grain bins must be closely followed to achieve the
full strength of the bin and to achieve adequate weather sealing. The product warranty is void if:
1. Wall sheets and/or uprights not specified for a given tier are used.
2. Foundations are found to be inadequate or out-of-level.
3. Anchor bolts (cast-in-place, drill-in, chemical type or other) are found to be inadequate.
4. Off-center loading or unloading is used. (This does not apply to the use of approved side unloading systems.)
5. Materials stored are not free-flowing or have a compacted bulk density greater than 55 lbs/ft3(880 kg/m3).
If using bin jacks during assembly, always lift on an upright. Choose a hoist with a adequate capacity for the
expected empty bin deadload. Make sure the rated capacity of the hoist is not exceeded.
3.5. Cutting Openings in Wide-Corr® Grain Bins
This section provides instructions for cutting openings to accommodate fan transitions, unloading augers and
roof vents.
General Rules for Cutting openings
1. Never cut any uprights, roof ribs, or wall sheet bolted vertical seams to create an opening.
2. Openings shall be located so equipment being installed won't interfere with any bin components/
accessories.
3. Openings shall be minimized as much as possible for structural integrity of grain bins.
4. Corners in openings shall be cut with minimum radius of 1/8" to reduce stress concentration.
5. Openings shall be sealed all the way around for all weather conditions.
6. Instructions shall be followed closely to avoid damage to bin structure.
7. Except cutting openings described below, any other modification to Westeel bins shall be approved by a
professional engineer.
Openings for Fan Transitions of Aeration Floors
1. Consult aeration floor installation instructions for information on Planning floor layout.
2. Openings shall be centered to a wall sheet in horizontal direction.
3. Opening shall be cut as tight as it can be for the transition to go through and shall have no more than 1/4"
gap on any side to the section of a fan transition going through a bin wall.
4. Opening height for fan transition shall be limited to 12.5" inches from bottom edge of a bottom wall sheet.
5. Opening width shall not exceed 46.5" for stiffened bins and 72.5" for unstiffened bins.
6. Vertical support shall be required to support load above opening.
7. Bottom angles may be cut flush to the sides of an opening to form part of opening.

Openings for Unloading Augers of Wide-Corr® Bins with Full Floor Aeration
1. Consult aeration floor installation instructions for information on Planning floor layout.
2. Openings shall be centered to a wall sheet in horizontal direction.
3. Openings shall be cut as tight as it can be for unloading auger to go through and shall have no more than 1/
4" gap to auger flange section on any side.
4. Opening height for any auger shall be limited to 12.5" from the bottom edge of a bottom wall sheet.
5. Vertical flange of a bottom angle may be cut flush to sides of an opening to form part of opening.
Openings for Roof Vents in Roof Sheets
1. Openings shall be centered between roof ribs and have 2.5" minimum distance between edge of opening
and base of a roof rib.
2. Openings can be square, rectangular, or round.
3. Openings shall be the same size as the inlet opening of a vent being installed.
4. Any side of a square/rectangular opening shall have a maximum length of 18" and a circular opening shall
have a maximum diameter of 24".
3.6. Critical Assembly Requirements
To ensure a successful, safe and reliable outcome you must comply with the following assembly techniques and
practices:
1. Comply with all local code and jurisdictional requirements applicable to your sealform installation.
2. Design and build foundations with the necessary strength for the loads they must support, and for local soil
conditions. Westeel foundation guidelines are based on specific stated conditions and may not be applicable
to local conditions.
3. Your foundation must provide uniform and level support to the structure being supported. Surface
imperfections causing gapping must be remedied. This may involve, but not be limited to a) grouting under
the bottom ring of a non-stiffened bin or tank, and b) shimming under the uprights of a stiffened bin or
tank, or under the legs of a hopper.
4. Make sure that the proper hardware is utilized for all bolted connections. If a shortage occurs, do not
substitute. Take the necessary steps to obtain the proper hardware. Make sure nuts are tightened to the
required torque values as specified in the appropriate assembly manual.
5. Comply with all assembly instructions provided in the appropriate assembly manual to make sure your
whole sealform is constructed safely. Important: Do not deviate from the wall sheet and upright layouts
provided.
6. Before anchoring your structure to its foundation, make sure the structure is round. The maximum variation
from perfect roundness is 3/4" on the radius. Locate anchor bolts toward the outside of the anchor bolt
holes (away from the circle) to permit the incremental expansion that can occur with the initial filling.
7. When installing roof stiffening rings, if it is necessary to shorten the stiffening ring tubes, shorten them as
little as possible. Initially the nuts on the expanders should be centered and as close together as possible.
When tightening, share the amount of take-up between expanders such that the nuts remain centered, and
the amount of engagement between all expanders on the same ring is equalized.
8. If extending an existing bin or tank, ensure that the foundation is adequate for the increased loads it must
support.
3. BEFORE YOU BEGIN CEW SEALFORM – WIDE-CORR® GRAIN BIN

194543 R8 13
9. If installing an existing bin on a hopper, make sure the bin is designed for a hopper application, and that the
foundation is capable of withstanding the substantial point loads that the hopper legs apply. If uprights are
present, make sure that they are supported.
10. Make sure that an integral end-to-end connection exists between all mating uprights. Successive uprights
must not overlap.
11. Vertical tolerances between uprights and wall sheets are tight. This can be affected by “jacking” techniques,
which can allow the tolerance to grow or shrink depending on the technique used. The gapping between
successive uprights must be monitored to ensure that upright holes align with wall sheet holes.
12. If catwalks are being installed on the structure, upright catwalk upgrades are likely required. The upgraded
stiffeners must be installed in the correct locations to support the intended catwalk loads. Also, the
structure must be properly oriented to ensure the eventual correct alignment between the catwalks and the
supporting uprights. Finally, the connectors that tie into the uprights and support the catwalks are best
installed during assembly of the structure. See the catwalk assembly manual for additional details.
3.7. Product Storage
Rust on Galvanized Parts
1. White rust forms when moisture is allowed to collect on galvanized surfaces that have yet to develop the
durable zinc oxide layer. This zinc oxide layer naturally occurs as the surface interacts with carbon dioxide,
and is characterized over time by the dull grey appearance that weathered galvanized surfaces get.
2. Parts that are not well ventilated or well drained can collect water between surfaces and develop white rust.
3. White rust is not a structural concern if its development is stopped in the early stages. A light film or
powdery residue can occur after a period of heavy rainfall or a short time of improper storage. If white rust
has started to develop, separate parts and wipe off any moisture. Next, using a clean cloth, apply a thin
layer of petroleum jelly or food-grade oil to the entire part.
4. If moisture is left on parts, this white rust can become more aggressive and turn into red rust. Red rust can
cause degradation in the material and become a structural concern. Any parts that have red rust should be
replaced immediately.
Storage Guidelines
• Keep all bundles dry before assembly of the bin.
• Start assembly as soon as possible.
• Do not lay bundles on the bare ground. Raise all bundles 6" to 8" off the ground on wood blocks or timbers.
(See Detail A in Figure 2 on page 14.)
• Store curved wall sheets ‘hump-up’. (See Detail A in Figure 2 on page 14.)
• All other bundles material should be placed so that they are well sloped to promote good drainage. (See
Detail B in Figure 2 on page 14.)
• Roof sheets must be elevated at least 12" at the small end of the sheets. (See Detail B in Figure 2 on page
14.)
• Temporary storage can be provided by erecting a simple framework supporting a waterproof tarp. (See
Detail C in Figure 2 on page 14.)
• All bin boxes, ladder boxes and hardware boxes should be stored inside. These are not waterproof, and will
deteriorate in normal weather conditions, allowing moisture to contact the parts inside.

If Parts Become Wet
1. If goods become submerged or wet, the
bundles should be opened as soon as possible,
sheets or material separated and dried. Keep
separated until assembly. Brace goods
properly so as to avoid damage or injury from
material falling when in storage.
2. Any boxed goods that become wet should be dried and stored in a new box that is free of
moisture.
3. In addition to wiping down wallsheets, a food-grade oil can also be applied with a clean,
lint-free cloth. This will assist in preventing any further moisture from contacting the
galvanizing on the steel. Due to safety concerns with installation and use, Westeel does
not recommend the use of oil on other parts such as roof sheets and safety ladders.

3.8. Grain Bin Use
• Do not off-center unload a grain bin. It is imperative to unload from the center of the bin first, until as much
grain as possible has been removed, and only then proceed to unload from the next closest unload gate to
the center. Continue utilizing the unload gates in succession from the center towards the outside. Gate
control mechanisms should be clearly marked and interconnected to prevent an external gate from being
opened first.
• The only exception to center unloading is when a properly designed and installed side draw system is
utilized. However, as bins tend to go out of round when employing side draws, the bin must be completely
emptied before refilling.
• When unloading a bin with a mobile auger through a properly designed auger chute, the entry end of the
auger should be pushed into the center of the bin before the auger is engaged. Slower rates of flow are
preferable and should not exceed the capacity of an 8” auger.
• Ensure that the inner door panels of grain bin doors are completely closed and latched before filling the
grain bin.
• Never enter a loaded grain bin for any reason. Grain can be a killer.
3.9. Important Notes
• Westeel does not provide a foundation design for this product, and is not liable for any damages or injuries
related to inadequately designed or constructed foundations. Customers must contract professional services
for all foundation design and construction work. For information on foundation design requirements, refer
to Section 3.2. – Foundation Design and Loads on page 10.
• In order to maintain your wall sheets in good condition separate sheets and allow air circulation between
them. Store sheets in a dry place. Do not store sheets with sheet ends pointing upwards.
• To keep an even pressure on walls, the bin must always be unloaded from the centre.

• Contact local power officials for minimum power line clearance.
• See Section 3.6. – Critical Assembly Requirements on page 12 for mandatory siting and assembly
requirements.
• Store only non-corrosive, free-flowing materials up to 55 lbs/ft3(800 kg/m3) average compacted density in
Westeel bins.
• Tighten all bolts to the recommended torque settings.
• Do not locate grain bins close to high buildings, which might cause snow to fall onto or build up on the roof
of the grain bin. Consider future expansion and allow space for loading and unloading of the bin. Your dealer
and local government agricultural consultants can help you plan your storage system for maximum
efficiency.

5. Assembly
Before continuing, ensure you have completely read and understood this manual’s
Safety section, in addition to the safety information in the section(s) below.
5.1. Assembly Safety
• Do not take chances with safety. The components can be large, heavy, and hard to handle.
Always use the proper tools, rated lifting equipment, and lifting points for the job.
• Carry out assembly in a large open area with a level surface.
• Always have two or more people assembling the sealform.
• Make sure you have sufficient lighting for the work area.
• Tighten all fasteners according to their specifications. Do not replace or substitute bolts,
nuts, or other hardware that is of lesser quality than the hardware supplied by the
manufacturer.
• Stay away from overhead power lines and other obstructions during assembly. Contact with
power lines can cause electrocution.
• Do not work in high winds.
5.2. CEW Sealform Disclaimer
Foundations are based on 4000 lbs. per sq. ft. (192 kPa) soil bearing capacity. All foundation designs use 3000
psi (21 Mpa) ultimate compressive strength (after 28 days) for concrete and 43,500 psi (300 Mpa) re-bar. The
foundation designs included in this manual are suggestions only, and will vary according to local soil conditions.
Westeel will not assume any liability for results arising from their use.
Important
Foundation must be uniform and level. Level should not vary more than ¼” over a span of four feet.
Application Notes:
1. Plan your installation before proceeding.
2. Forms may be used for In-floor Aeration and unloading systems with inclined powerheads.
Note
•SEALFORMS ARE DESIGNED FOR A MAXIMUM OF 8 TIERS FOR 15-27’ DIAMETER BINS AND A
MAXIMUM OF 7 TIERS FOR 30-33’ DIAMETER BINS.
•BINS ON SEALFORMS SHOULD NOT BE FILLED UNTIL CONCRETE HAS FULLY CURED FOR A
MINIMUM OF 28 DAYS
5.3. Foundation Specifications
1. Choose a site which is well drained and has a minimum soil-bearing capacity of 3700 lbs per sq. ft. (177 kPa).
If soil-bearing capacity is not known, consult a local engineering consultant.
2. Use a minimum of 4” to 6” (100-150 mm) of well compacted coarse gravel below slab and ring footing.
