Tanks and silos are often the heart of an operation and store critical elements to the process of a facility. If they were allowed to rust and corrode to the point where replacement is the only option, what would be the impact to the company from down time? We regularly refurbish tanks and silos without down time to the customer for a fraction of the cost to replace. Like anything, proper maintenance is the key.
They are also something the public and your customers see which gives them a perception of your company. If silos and tanks are dirty and corroded what do customers think? Would a clean, shiny, silo with a company logo improve perception?
