Engineered Protection for Below Grade Steel Structures
AZZ provides specialized below grade coating services for steel structures across multiple industries, with a strong focus on transmission and distribution (T&D) infrastructure.
Our coatings safeguard critical components against corrosion caused by soil, moisture, and buried exposure. For utility providers and fabricators, this translates into extended asset life, reduced maintenance, and enhanced reliability.
High-Performance Coatings for Harsh Environments
Our below grade coating systems are designed to perform in the most demanding underground conditions. Each system is selected based on exposure levels, application requirements, and longevity expectations. With decades of experience serving the utility sector, AZZ delivers dependable, field-tested protection—ensuring that the steel backbone of the grid remains strong where it’s most vulnerable: below the surface.
Precision Blasting and Surface Preparation
Achieving long-term performance starts with proper surface preparation. At AZZ, we utilize abrasive blasting techniques to remove rust, mill scale, and surface contaminants, creating a clean and profiled substrate for optimal coating adhesion. Our facilities are built to accommodate the size and complexity of T&D structures, ensuring consistent preparation that meets or exceeds industry standards for below grade corrosion protection.
