DISCLAIMERS 

Foundation Design 

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. 

Method of Erection 

The recommendations for erecting Westeel Grain Bins should be closely followed to achieve the 

full strength of the bin and to achieve adequate weather sealing. Warranty is void if the 

recommendations are not followed including but not limited to: 

1. Wall sheets and/or uprights, which are 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/ft 3 (880 kg/m 3 ). 

If using Bin Jacks: Always lift on an upright. Choose a hoist with a suitable capacity for the 

expected empty bin deadload. Make sure the rated capacity of the hoist is not 

exceeded. 

These Westeel Grain Bins are designed for: 

Design 

1. Non-corrosive, free-flowing materials up to 55 lbs/ft 3 (880 kg/m 3 ) 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. 15.0 lbs/ft 2 (.72 kPa) roof snow load. 

24.0 lbs/ft 2 (1.15 kPa) roof snow load when the optional roof stiffening rings are installed. 

5. 4000 lbs. (17.8 kN) evenly distributed on peak ring for 15’ – 24’ bins. 

5000 lbs. (22.2 kN) evenly distributed on peak ring for 27’ – 48’ bins.

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; and 

• Interconnections with neighbouring structures. 

• 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. 

Critical Assembly Requirements 

1. Local code and jurisdictional requirements that are applicable to the grain bin installation 

must be adhered to. 

2. Foundations must be designed for the loads being imparted to them, and for local soil 

conditions. Westeel foundation guidelines are for a set of stated conditions and may not 

be applicable to local conditions. 

3. A foundation must provide uniform and level support to the grain bin structure being 

supported. Surface imperfections causing gapping must be remedied. This may involve, 

but not be limited to - grouting under the bottom ring of a non-stiffened bin, and shimming 

under the uprights of a stiffened bin or under the legs of a hopper. 

4. If extending an existing bin, ensure that the foundation is adequate for the increased loads 

that will be subjected to it. 

5. If installing an existing bin on a hopper, ensure that 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, ensure that they are supported. 

6. Ensure that the proper hardware is utilized for all bolted connections. Refer to the 

‘Hardware “Where Used” Chart’ in the Installation Manual. If a shortage occurs do not 

substitute. Take the necessary steps to obtain the proper hardware. Ensure nuts are 

tightened to the required torque values as provided in the Installation Manual. 

7. Refer to the appropriate Installation Manual to ensure a safe, proper structure, in 

particular but not exclusively for the wall sheet and upright layouts. Do not deviate from 

the layouts provided. 

8. Ensure that an integral end-to-end connection exists between mating uprights. 

Successive uprights must not overlap. 

Page 7

9. 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 bin sheet holes. 

10. When installing roof stiffening rings, and 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 takeup 

between expanders such that the nuts remain centered, and the amount of 

engagement between all expanders on the same ring is equalized. 

11. Before anchoring the bin to the foundation, ensure that the bin is round. The maximum 

variation from perfect roundness is 3/4" on the radius (see details in "wall sheet and 

bottom angle " section of manual). Locate anchor bolts towards the outside of the anchor 

bolt holes (away from bin) to permit the incremental expansion that can occur with the 

initial filling. 

Grain Bin Use 

1. 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. 

2. 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. 

3. 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. 

4. Ensure that the inner door panels of grain bin doors are completely closed and latched 

before filling the grain bin. 

5. Never enter a loaded grain bin for any reason. Grain can be a killer. 

Rust on Galvanized Parts 

Product Storage 

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. 

Page 8

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 

1. 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” – 8” off the ground on wood blocks or timbers. 

Store curved wall sheets ‘hump-up’. All other 

bundles material should be placed so that they are 

well sloped to promote good drainage. 

2. Roof sheets must be elevated at least 12” at the 

small end of the sheets. 

3. Temporary storage can be provided by erecting 

a simple framework supporting a waterproof tarp. 

4. 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. 

Page 9

IMPORTANT NOTES 

1. 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. 

2. To keep an even pressure on walls, the bin must always be unloaded from the centre. 

3. Contact local power officials for minimum power line clearance. 

4. See "Disclaimers - Design" for materials which can be stored. 

5. Tighten all bolts to the recommended torque setting (see Recommended Bolt Torques 

table in Appendix). 

6. Do not locate grain bin 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. 

Shortages and Damaged Parts; 

Report damaged parts or shortages immediately to the delivering carrier, followed by a 

confirming letter requesting inspection by the carrier, if required. Order any replacement parts 

immediately to ensure that assembly will not be held up by missing parts. All parts will be 

charged for and credit will be issued by party at fault - no credit will be issued if freight bill are 

signed as received in good condition. 

Order Optional Equipment; 

Optional equipment such as unloading augers, aeration equipment, anchor bolts, foundation 

sealant, external ladders, safety cage and platforms, etc., should all be on site and checked 

before assembly starts. Plan your installation in advance. For details, see assembly 

instructions supplied with optional equipment.
