From iconic bridges and skyscrapers to industrial facilities, stadiums, and transit networks, PPG Protective Coatings are trusted to deliver exceptional performance where it matters most. Our comprehensive portfolio includes advanced corrosion protection systems that shield steel and concrete structures from harsh environments, extending asset life cycles and reducing costly maintenance.

These solutions are engineered to expand and insulate steel during a fire, buying valuable time to protect lives and investments.

At PPG, sustainability is more than a promise — it’s a guiding principle. Our protective coatings help customers lower their environmental footprint through extended maintenance intervals, reduced resource consumption, and innovative low-VOC and high-solids technologies that meet or exceed global environmental standards.

Around the globe, PPG’s protective coatings safeguard critical infrastructure against corrosion, weathering, abrasion, and chemical exposure — ensuring bridges stand tall, tunnels remain safe, and buildings retain their strength and beauty for decades to come. Backed by dedicated technical support, global supply capability, and continuous research and development, PPG is the trusted partner for infrastructure protection — today and for generations to come.
