The 500 kV Surat Thani–Phuket Transmission Line is a critical infrastructure project spanning 200 km, with a 110-km section running through dense jungle and mountainous terrain. As part of this high-voltage installation, Rust-Oleum 5281 gray primer, 5258 tower orange, and 5291 tower white were used to coat and identify transmission towers along the route.

These industrial-grade coatings were selected for their outstanding weather resistance, UV stability, and long-term adhesion under extreme environmental conditions. The system ensures high visibility, corrosion protection, and durability—supporting safe operation and extended service life in one of Thailand’s most technically demanding transmission corridors.
