Chapter 1: Safety Precautions
Unload the Bin Correctly
• Use CENTER FLOOR OUTLET ONLY until NO grain
remains above this outlet.
• Side floor outlets to be used ONLY when above condition
is satisfied.
• Lock all side floor outlets to avoid accidental premature
use.
• See manufacturers instructions for proper use of factory
supplied sidedraw (wall) discharge systems.
ST-0060–1
Prevent Roof Damage Due to Vacuum Pressure
• Roof damage can result from excessive vacuum or internal
pressure from fans or other air moving systems. The manu-
facturer does not warrant this type of roof damage.
• Adequate ventilation or “makeup air” devices must be pro-
vided for all powered air handling systems.
• The manufacturer does not recommend the use of down-
ward flow systems (suction).
• Severe roof damage can result from any blockage of air
passages.
• Operating fans during high humidity or cold weather condi-
tions can cause air exhaust or intake ports to freeze.
ST-0028–2
Sharp Edge Hazard
• This product has sharp edges, which can cause serious
injury.
• To avoid injury, handle sharp edges with caution and always
use proper protective clothing and equipment.
ST-0036–2
PNEG-5442 42' Diameter EVO-50 Z-Tek Bins 11

installation. Not following these safety precautions creates
the risk of falling equipment, which can crush personnel and
cause serious injury or death.
ST-0047–1
Do Not Overfill the Bin
• Do not overfill bin. Stored grain must be no higher than the
roof eaves at the outer edge.
• Filling the bin above this point creates excessive internal
pressure and can cause swelling and eventual roof failure.
The over filling of a bin can also cause the blockage of roof
vents and eaves, which will lead to a build-up of air pres-
sure causing roof damage.

▪ Anchor Bolt Charts
General Information
General information, overview and instructions needed before performing work.
Read this manual carefully. This manual will provide instructions on building the sidewall and stiffeners.
You will also need to refer other instructions in building the bin.
These include, but may not be limited to:
• A stiffener and sidewall gauge layout chart is required. If such a chart is not included with this
manual, contact GSI.
• Roof instructions must be followed. Roof instructions are included in this manual.
• Ladders, roof stairs, roof handrails and other products are covered by separate instruction manuals.
Refer to the appropriate accessory manual. Inside ladder instructions are included in this manual.
• Aeration systems and transitions are to be installed according to the instructions provided with the
system or transition.
• It is critical that the anchor bolts are installed and spaced correctly.
Tools Required for Construction
General tools needed to perform this construction:
• Combination wrench set 7/16" to 1"
• Combination wrenches for 17 mm and 19 mm
• Alignment punches 12" long
• 1/2" Drive socket set and ratchet
• Nail aprons or tool pouches to hold supplies
• Gloves for hand protection
• Tape measure
• 1/2" Drive electric or pneumatic torque gun with variable impact capabilities
PNEG-5442 42' Diameter EVO-50 Z-Tek Bins 17

Chapter 2: General Overview
• 1/2" Drive impact socket set
• Lifting jacks
• Center pole roof support
• Step ladders
• Large C-clamp or welding V-grip for clamping
NOTE: Quantities required will depend on the number of workers and size of the bin.
Guidelines for Proper Storage of Grain Bin Materials Prior to
Construction
Storage of the build materials prior to construction is important. Do not to allow moisture to remain
between sheets or panels.
• 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 sheets. 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 and spacing materials
should 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 immediately about ways to
minimize the adverse effect upon the galvanized coating.
Overview for a Typical Bin Installation
These are the typical steps one would perform when constructing a grain bin. Procedures may vary
depending on the site requirements.
Pre-Assembly Activities
• Sorting and grouping parts.
• Install the wind ring bracket to the stiffeners.
• Assemble the rafter clips to rafters on the ground.
• Assemble the A-frames.
• Assemble the center collar.
• Install the vent to the roof panels.
18 PNEG-5442 42' Diameter EVO-50 Z-Tek Bins

Chapter 2: General Overview
Assembly
• Build one ring of sidewall and make sure to caulk all seams.
• Add top outside stiffeners and inside stiffeners at the same time to the rings of the sidewall sheets
NOTE: These top stiffeners are the lightest gauge stiffeners and will get heavier as the bin is raised.
Therefore, the heaviest stiffeners are located at the bottom of the bin and are installed last.
• Install the wind ring to help support the rings.
• Install the center collar tower support in the center of the bin.
• Install the eave brackets to the inside stiffeners.
• Install the eave angles to the sidewall sheets. (Note how these are aligned.)
• Install the tension member and/or compression channels to the eave brackets.
• Lift the pre-assembled A-frames, installing them in “opposite pairs” (across from one another) to
balance out the load as you install.
• Install the roof panels.
• Cut roof exhauster holes evenly spaced in roof panels.
• Install the roof flashing and peak cap.
Guidelines for Construction Procedures and Lifting Jack Usage
The following procedure is a guideline when using a lifting jack. Follow this general guideline when lifting
the bin as sidewall sheets are being installed.
NOTE: The roof and the top ring for odd ringed bins or the roof and 2 rings for even ringed bins, will be
installed prior to the beginning of bin lifting procedures. Refer to all other procedures on sidewall
and stiffener installation prior to the start of construction.
IMPORTANT: Begin building with the bin oriented for doors and material handling equipment to be in the
correct position when bin construction is complete.
1. Consider the starting location of the bin, relative to the location of the doors and other accessories.
Proper placement of lifting jacks in relationship to anchor bolts could make a difference in final
locations. Note that the sidewall sheets will be staggered.
2. The bin is lifted by the use of lifting jacks. Lifting jacks are used to slowly and evenly lift the bin
during construction. Lifting jacks must be properly sized and designed to carry all loads and job site
conditions associated with the construction of the bin.
• The number of lifting jacks required is best determined by personal experience and expertise.
Factors such as bin size, jack design, construction conditions, support surface, etc., are all to
be considered when deciding how many to use. If in doubt, use one jack on every sheet.
• The lifting jack must be adequate to carry all loads. Heavy duty jacks, generally hydraulic or
electric powered in the case of large bins, should be used for commercial installation. All jacks
should be secured with braces or otherwise maintained in a stable condition.
• Lifting of the bins should not be done under windy conditions.
• Follow the jack manufacturers recommendations on capacity and operations.
PNEG-5442 42' Diameter EVO-50 Z-Tek Bins 19

Chapter 2: General Overview
3. Lifting brackets should be attached through the stiffener bolt holes. Normally you will need to attach
at least four bolts per stiffener.
4. Raise the bin just high enough to assemble the next ring. When lifting the bin, all jacks must lift at
an equal rate. Monitor the lift to ensure even lifting is occurring.
5. To the inside of the first ring, bolt the next ring. Be sure to stagger the sheets and select the proper
gauge material.
6. Lower the bin onto the foundation after assembling and tightening bolts on the new ring or rings.
7. Attach stiffeners to the body sheets every two tiers (on the external surface of the bin). You may
want to leave sheets loose to make the attachment of the stiffeners easier.
8. Now re-bolt the lifting brackets to the lowest ring in place thus far. Continue ring additions by
repeating step 5, page 20 and step 6, page 20.
9. Add inside and outside ladders as you continue to raise the bin. (Refer to the manual supplied with
the ladders and platforms.)
10.Add platforms as you raise the bin. (Refer to the manual supplied with the ladders and platforms.)
11.Lower the tank and secure to the foundation before leaving the job site.
12.At the completion of the tank, set stiffeners over the anchor bolts and measure the tank to ensure it
is in a round condition. Consult with GSI for questions on tolerances.
