Adding Strength to Existing Silos

Hanson’s hoops from rods encircle stave silos for stability.

Secure your spherical structure and increase ductility with Hanson’s silo rods and hoops. We can provide replacement and additional hoops for safety of the hopper bottom steel bins. These hoops have integrated vibration to loosen the stored content, preventing the bolted seams from failure. Water tanks made of wood are also a great candidate for Hanson’s safety rods.

Silo Rod Stability

Hanson fabricates each rod and adds an electro-galvanized coating.


Hanson Silo rods have many different uses, including adding strength to a depleting structure. We use rods to form hoops which encircle stave silos and carry the tension load of the silo wall, increasing tensile strength, as measured by yield point, and ductility as indicated by elongation.

  • Fabricated with a cold-forged thread on each end and an electro-galvanized coating, supplemented with chromate finishes
  • Stock length rods are manufactured in 9/16″ diameters with a 6″ thread on each end
  • Electroplated dichromate finish
  • 40,000 psi minimum yield point with 20% minimum elongation

When choosing rod combinations or hooping systems, consider these guidelines. These systems are based on 9/16″ diameter rods with 5/ 8″ rolled threads.

Steel lugs are used to fasten rods and make a hoop. They are manufactured to match the rod diameter and strength of the standard hooping systems.
