T.C. Pharmaceutical carried out maintenance work on the steel structures of its production facilities 3, 5, and 7 at the Ban Sang site in Prachinburi. Rust-Oleum 769 primer and 473 aluminum finish were selected for the project due to their strong adhesion, corrosion resistance, and proven performance in industrial environments.

These coatings extend the life of structural steel while offering a clean, professional finish—helping maintain operational safety and infrastructure integrity across the plant.
