Silos may be constructed as single-piece welded steel fabrications or they may be built on-site with bolt-together steel or aluminum circular sections. The cone angle is designed for the material being stored and multiple options are available to minimize maintenance and make the silo accessible to authorized personnel. Various styles of level sensors are available and material levels can be automatically monitored to trigger re-ordering of material.

Typical optional and accessories include:

• Caged ladders, railings and catwalks
• Choice of level sensors
