When should I use a bolted silo?

We will generally recommend using a bolted silo whenever the size or shipping constraints require the silo be field erected. In North America the practical limit on a shipable silo diameter is 14’ so anything larger than that will need to be field erected. We may also recommend bolted silos for shipments that are going overseas, or where there is no permanent road access. For applications requiring larger than 14 foot diameter, bolted silos are a good alternative to field welded silos, both from a cost and schedule standpoint.
