4. STIFFENED SILOS
DOOSON silos offer many outstanding
strength and durability features.
Wide corrugated steel sheets manufactured
from high strength steel, heavy duty
galvanized steel stiffeners and strong roofs
are some of the quality features available.
DOOSON complete line of commercial silos
is available in diameters from 15feet(4.57m) to
DOOSON also has a full range of accessories
available to complete your storage installation.
We can handle the pressure
The profile of DOOSON stiffeners are computer-designed for optimum
load-bearing capacity, ease of installation and manufacturing efficiency.
Upright stiffener columns transfer the bin load straight to the foundation
and can be mounted internally or externally as required.
Stiffener slices are offset from sidewall seams for improved structural
integrity and easier instal lation.
All bins have at least two stiffeners per sidewall sheet, while larger
capacity bins have a third stiffener for the increased load-bearing capability
and vertical stability that their size demands.
Bearing the load…
DOOSON super stiffeners take strong & hot dip galvanized steel.
The shape of the super stiffeners surpasses the compressive strengths
of previous open-faced stiffeners.
This profile can handle the drawdown loads
imposed by very tall silos, as well as severe seismic loads.
Each silo utilizes several stiffener gauges and up to three profiles for
the most efficient column design.
Heavy-duty stiffeners transfer drawdown loads from the side-walls to
Stiffener base plate is factory-welded to bottom stiffener providing durable
silo anchorage to resist and uplift loads.
5. TOUGH BINS FOR A TOUGH BUSINESS
6. ROOF SYSTEMS
DOOSON structured roofing system delivers a
standard peak roof load of 10,000lbs(5,550kg).
Higher peak roof load options of 20,000lbs(9,000kg),
and over are also available when desired.
That means you will have all the support you
need for conveyors, spouting, temperature
cables and other ancillary equipment without
Intermediate structural supports deliver maximum
strength to our special structured roofing system
for larger bins heavy loads.
Let's start at the top
DOOSON’s super-deep roof ribs-varied in depth
according to the size of the bin-ensure strength
and structural integrity.
All roofing options come with a durable galvanized
design for roof supports, roof panels and other
major components for lasting strength and weather
Put it all together and you have a roof structure that
can carries its weight.
Putting it all together…
DOOSON manufactured from galvanized steel are
provided for bolting to the roof around the perimeter
of the peak cap.
Super deep roof ribs-varied in depth to match your
bin size on structured roof models-also help to ensure
proper and structural integrity.
All seams are fully double-overlapped for maximum
7. SIDEWALL PANELS
Up and down all around – DOOSON offers
the perfect combination of stiffener columns
and support rings to handle the pressure,
inside and out.
Sidewall panels are designed & manufactured in
our own factory under our strict manufacturing
DOOSON bins are performance-tested and
field-proven to withstand the most demanding
Our attention to detail in sidewall manufacturing
is one reason why.
Bearing the heaviest loads
Bins are attached to the concrete at the base of the
stiffener-transferring the entire vertical load of the bin
to the concrete foundation.
Today’s bigger bins demand dependable vertical stability
and load-bearing capability.
With DOOSON, that’s exactly what you get.
Convenient handling and
Rugged upright stiffener columns transfer the bin load
straight to the foundation.
Stiffeners can be internally or externally mounted
according to your specifications.
On smaller capacity bins, there are two stiffener
columns per panel.
Easy access walk-in door
Extra large side doors provide
convenient two-way access.
Fully galvanized, heavily reinforced
and suited for two and three stiffener
8. AERATION & DRYING SYSTEMS
Proper aeration is an important part of every
grain storage system and is essential to
maintaining grain quality.
Properly operated aeration systems help control
insect infestation and moisture migration,
reducing grain spoilage and saving money.
DOOSON's aeration system can be installed
in new or existing storage facilities.
We use rigid corrugated, perforated aeration
ducts made from heavy gauge galvanized steel combined with high efficiency aeration fans.
Maximum airflow and strength
Your grain deserves protection from the bottom up to
maintain grain quality and proper airflow.
DOOSON has the right floor and floor support system to
match your needs – and give you the perfect combination of
open area and load-bearing strength.
All DOOSON floors, floor supports and flashing are built for
years of dependable service.
Silos that help protect your
DOOSON silo system can include aeration, drying, temperature
monitoring and silo unloading-all designed to assure grain quality
and your profitability.
Timing is everything in the grain business and can sometimes
mean the difference between profit and less.
That's why you need grain storage and drying system that allows
you to get your crop out of the field when you're ready- and to
preserve grain quality when you need it most.

Supporting columns are wide-flanged beams with heavy-duty tie-road braces, bolted solidly to the steel
A heavy-duty compression ring ties the bin components securely to the
galvanized hopper cone.
Strong legs to stand on
DOOSON hoppers feature galvanized hopper lates which
are supported by DOOSON's unique compression ring
assembly for additional strength.
This effective transfers the bin load from the hopper onto
the legs and into the bin foundation.
A steel sealing strip is continuously welded to the
compression ring assembly to ensure a moisture tight fit.
Quick and complete grain
The vertical load in the hopper bin is transferred down the
stiffeners to the support columns which are anchored
directly into the concrete base.
Rack and pinion designed also ensures the slide gate
operates smoothly and it allows for extremely accurate
size adjustments of the opening.
This hand-operated gate is standard on DOOSON
commercial hopper bins.

11. DART SYSTEMS - INTELLECTUAL PROPERTY RIGHTS
The automatic control system of temperature
and humidity of grain bins for quality grain
On the quot;Autoquot; mode, the stirring machine and
fan will automatically start with a warning alarm
when the difference in temperatures between
the stored grain and outside air exceeds a
certain point. And, they will stop automatically
when the temperature difference comes within
the safe zone.
