Flat Bottom Silo | Bidragon Steel Silos
A flat bottom silo from Bidragon is described as one of the most commonly used steel silos in agriculture and as the most popular and cost-effective way of long-term storage, especially for grain and feed. The product documentation states that a flat bottom silo needs full support from a level ground surface, that the ground design is decided by the stored material, and that a flat bottom air slide can be bolted to embedded ground parts or fixed directly to the silo bottom.
The product documentation states that all flat bottoms are designed and built to the D-4097 or ASTM D-3299 standard. That is a design standard statement, not a company certification, and it is reported here as such. For cement, fly ash and similar materials that need a fluidisation system, the flat bottom silo is generally presented as the first choice in the product documentation, as a recommendation rather than a performance guarantee.

Applications
Flat bottom silos serve farms and feed and grain operations where long-term storage on a prepared foundation is planned. The foundation design and the fluidisation requirement for fine materials should be settled early in the inquiry, because they affect the ground works as well as the silo itself.
How this product fits in a storage line
Storage silos are normally planned around the foundation, the discharge method and the handling line. A flat bottom needs full support from a prepared ground surface, a hopper bottom is chosen where complete emptying matters, and an elevated arrangement is chosen where gravity discharge height matters. A buyer comparing storage silos should therefore settle the foundation plan, the discharge arrangement and the connection to conveyors or packing equipment at the same time as the silo size, because those decisions affect each other.
What to confirm in your inquiry
Because silo requirements depend on the material, the site and the handling system, the following items are confirmed per project before any quotation is issued. Sending these details with your inquiry helps the supplier respond with a workable proposal rather than a generic price.
- Material to be stored, including bulk density, moisture content and flow behaviour, and whether the material is free-flowing or prone to bridging.
- Required storage capacity and any future expansion allowance, together with the available footprint and height limit at the site.
- Discharge method and downstream equipment, such as a screw conveyor, a pneumatic conveying line or a packing machine.
- Roof and bottom configuration, including whether a flat bottom, hopper bottom or elevated arrangement suits the discharge and foundation plan.
- Ventilation, level measurement, temperature monitoring and dust control requirements, where the stored material or local rules call for them.
- Surface protection and coating requirements, the installation method available at the site, and the delivery scope expected from the supplier.
- Any applicable design standard or local code that the project must follow, so that the proposal can be checked against it.
