Galvanizing
Industry-leading galvanizing network delivering durability, scale, and performance
For more than 250 years, galvanizing has been trusted to protect steel and iron from the damaging effects of corrosion. Today, it remains one of the most effective, economical, and sustainable methods for extending the service life of fabricated steel used in bridges, substations, utility structures, transportation infrastructure, industrial facilities, and construction applications across North America.
North America’s largest galvanizing network for fabricated steel
As North America’s largest hot-dip galvanizer of fabricated steel, AZZ delivers industry-leading galvanizing capabilities backed by one of the industry’s largest operational footprints across the United States and Canada. Through responsive service, scalable production capacity, quick-turn project execution, and advanced galvanizing technologies, AZZ helps customers improve asset durability, reduce lifecycle costs, and enhance infrastructure longevity.
The galvanizing process involves immersing fabricated steel into molten zinc, where the zinc reacts metallurgically with the steel to form a tightly bonded alloy coating. This protective barrier helps shield steel from corrosion for decades, while minimizing maintenance requirements and reducing long-term ownership costs.
AZZ Galvanizing includes both Hot-Dip Galvanizing and Spin Galvanizing solutions tailored to different fabrication sizes, component types, and performance requirements. From large structural steel and infrastructure components to smaller threaded and precision parts, AZZ galvanizing services are engineered for construction, electrical, industrial, and transportation markets requiring dependable corrosion protection and scalable galvanizing capacity.
Scale, capacity, and industry-leading capabilities
AZZ operates more than 40 galvanizing facilities strategically located throughout the U.S. and Canada, helping customers reduce transportation costs, improve turnaround times, and efficiently manage multi-location and large-scale fabrication projects.
This expansive footprint allows AZZ Galvanizing to handle a broad range of fabrication sizes, production volumes, and schedules while delivering dependable coating quality and production reliability across North America. Whether supporting utility transmission infrastructure, transportation systems, renewable energy, industrial manufacturing, or large-scale construction, AZZ provides the scale, responsiveness, and capacity customers rely on to support complex production schedules and infrastructure demands.
Supporting this network is AZZ’s proprietary Digital Galvanizing System (DGS), which provides near real-time order visibility, production tracking, status updates, and customer notifications throughout the galvanizing process. DGS helps improve scheduling, coordination, communication, and overall efficiency across AZZ’s galvanizing operations.
In addition to our large-scale footprint and production capacity, AZZ supports accelerated timelines and quick-turn requirements through responsive scheduling, integrated logistics, and customer-focused service support.
Why galvanizing
Galvanizing provides lasting corrosion protection that significantly extends the service life of fabricated steel while reducing maintenance and replacement costs over time. Unlike painted or epoxy-coated surfaces that may require ongoing maintenance and recoating, galvanized steel can deliver decades of corrosion protection with little to no required coating maintenance.
Galvanizing also provides a cost-efficient alternative to more expensive materials such as stainless steel and aluminum while helping improve asset durability and lifecycle value.
The process creates complete coating coverage across edges, corners, welds, and difficult-to-reach areas, helping provide consistent corrosion protection throughout the entire fabricated component. The metallurgically bonded zinc coating also delivers exceptional abrasion resistance and durability during transportation, handling, and installation.
From bridges, substations, and transmission structures to industrial facilities, transportation infrastructure, and renewable energy projects, galvanized steel continues to play a critical role in supporting stronger, longer-lasting infrastructure across North America.
Sustainability and environmental benefits
Galvanized steel represents a highly sustainable corrosion protection solution. Essential zinc and steel are both recyclable materials, and galvanized steel structures can remain in service for decades before requiring replacement, helping conserve raw materials and reduce environmental impact over time.
The galvanizing process itself produces no volatile organic compounds (VOCs) or hazardous air pollutants associated with many alternative coating systems. Galvanized steel also contributes to sustainable building initiatives and may support LEED certification efforts through durability, recyclability, and reduced lifecycle maintenance requirements.
As infrastructure demands continue to grow across utility, transportation, renewable energy, and industrial markets, galvanizing remains a critical solution for protecting infrastructure investments while supporting sustainable infrastructure development.
GalvXtra® proprietary galvanizing performance
To help ensure exceptional coating performance and finish quality, AZZ utilizes its proprietary GalvXtra® galvanizing formulation. This proven process technology is designed to deliver a more uniform coating appearance, improved finish consistency, and enhanced performance across a broad range of fabricated steel applications.
GalvXtra® has been field-tested and proven to help minimize irregular coating reactions while supporting durable, high-quality galvanized finishes. The process meets internationally recognized ASTM quality standards, including ASTM A123, ASTM A153, and ASTM B6 for zinc coatings on ferrous materials.
Recognized industry excellence
AZZ’s galvanizing expertise has contributed to numerous award-winning projects recognized throughout the industry for excellence in hot-dip galvanizing applications.
Each year, the American Galvanizers Association (AGA) recognizes outstanding projects demonstrating the performance, durability, versatility, and innovation of hot-dip galvanizing through its Excellence in Hot-Dip Galvanizing Awards program. AZZ is proud to support projects and customers whose work continues to showcase the value and performance advantages of galvanized steel across North America.
