Fixed roofs for above-ground storage tanks typically have a diameter less than 120', but can be much larger with additional support columns. Steel fixed roofs include:
Self-supporting cone roof
Steel dome roof
PTS' roof repair services and capabilities include:
Cone Roof Repair
As storage tanks age, rain water and vapor corrode the roof plate and structural beams. Based on the condition of your tank, the fixed roof may require patch plate, structural repair, or complete replacement. Based on a third-party inspection report, PTS engineers will work with you to create a cost-effective repair plan.
Anaerobic Digester Cover Repair
Tank systems with anaerobic digesters are increasingly popular due to the renewable industry. We will work with you to repair and recommission the existing cover. PTS has the experience to repair any welded steel digester cover on the market.
