  4. 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 105feet(32m). 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 foundation. Stiffener base plate is factory-welded to bottom stiffener providing durable silo anchorage to resist and uplift loads.
  6. 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 worry. 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 resistance. 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 strength.
  7. 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 specifications. DOOSON bins are performance-tested and field-proven to withstand the most demanding conditions. 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 easy-access 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 designs.
  8. 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 investment 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. DOOSON dry system is a complete for drying, cooling and storing grains of many types-and has a record of outstanding performance in the field.
