How to address corrosion and protection at the bottom corners of towers, containers, and storage tanks?

After looking at the pictures posted by the original poster, the corrosion at the bottom corners of this tower is indeed quite typical – it results from fluids or moisture from the outside environment flowing down along the tank surface and accumulating in those corner areas, leading to localized rusting. Here are some practical suggestions for your reference: First, thoroughly remove rust by sanding off any loose rust and old paint layers. Then apply the appropriate anti-corrosion primer and topcoat. For outdoor storage tanks, it is recommended to use epoxy or polyurethane coatings with high weather resistance, as this will provide longer-term protection ； Simple guards can be installed at the gaps between the bottom corners and the foundation to reduce the accumulation of rainwater and dust, and to prevent moisture from remaining on the metal surface for long periods ； If the corrosion is already quite severe, it’s best to conduct a wall thickness inspection first to prevent leakage due to perforations. For professional anti-corrosion treatment and testing, it’s advisable to hire qualified teams in this field to ensure safety.
