Utilizing commercially available and patented anode alloys, STRUCTURAL TECHNOLOGIES’ metalized cathodic protection systems are designed to deliver corrosion protection to embedded reinforcing steel in concrete through the galvanic process.
When connected to reinforcing steel in concrete, a metalized anode system delivers a uniform protective current. Simple to operate, these systems do not require external power and offer lower lifecycle costs compared to other methods of cathodic protection. A metalized surface may also be coated for aesthetic purposes or to provide additional protection.
When properly designed and installed, our Metalized Cathodic Protection Systems are:
Steel and other metals exposed to corrosive environments benefit from the unique protective characteristics of thermal spray technology. STRUCTURAL TECHNOLOGIES works with engineers owners and operators to select the appropriate thermal sprayed coating that best protects the specific structure. Selection factors include the material composition of the structure and the associated corrosive contents of a structure and/ or the surrounding atmospheric environment that the structure is exposed to on a daily basis.
Thermal Spray Coating Materials
Thermally sprayed coatings are obtained by melting a material, atomizing it into small particles and propelling these on to a prepared substrate. The resulting coating cools down and forms a barrier with unique characteristics. These include strong bonds and resistance to atmospheric corrosion, high temperatures, corrosion, and chemical attack.
Thermal spray coatings of zinc, aluminum and their alloys are chosen to protect steel for a number of reasons including both their resistance to corrosion in atmospheric environments. and because they act as a sacrificial coating that protects the steel galvanically. Specialty alloys based on Nickel, Chromium, and other proprietary alloys are selected for high temperature and erosion corrosion typically present in flue gas path environments. Our corrosion engineers assist in selecting the proper coating that may include:
- Zinc/Aluminum 85-15
- ArcMelt® Flue gas path and chemical environment alloys.
These systems are typically installed using the wire arc method, a process where two wires of metal are energized and melted, then propelled towards a prepared surface at a high speed to create a dense coating that adheres strongly to the substrate.
STRUCTURAL TECHNOLOGIES helps develop the application-specific installation method, and also provides equipment, alloy coatings and expert technical field support, as well as quality assurance / quality control.
STRUCTURAL TECHNOLOGIES’ Corrosion Team provides highly specialized investigative and engineering services. Our team integrates with owners, engineers and builders to provide or assist in initial assessment and design – in order to identify the root cause of the corrosion and determine the proper solution for the individual application.

Corrosion Engineering Team Leader
Jorge Costa, P.E.
Jorge Costa is Vice President of STRUCTURAL TECHNOLOGIES’ Corrosion Solutions Team that provides engineering, design, quality assurance and monitoring of corrosion control systems. He also guides our efforts in research and development of innovative means of corrosion protection for concrete structures. A NACE-certified Corrosion and Cathodic Protection Specialist, Jorge has specialized in the corrosion assessment of reinforced concrete structures, design and installation of corrosion control systems for concrete and steel structures, cathodic protection and thermal sprayed coating systems for more than 30 years. Jorge is a licensed Corrosion Engineer in the State of California and a licensed Professional Engineer in Florida.
Jorge is an active member of various industry technical committees, including the American Concrete Institute (ACI), the International Concrete Repair Institute (ICRI), NACE International - The Corrosion Society (NACE), and the American Welding Society (AWS). In this capacity, he is a key contributor for the development of guides, standards and recommended practices issued by these committees. Specific committees where Jorge serves include ACI 222 – Corrosion of Metals in Concrete, ACI 364 – Rehabilitation of Concrete Structures, ACI 546 – Repair of Concrete, AWS 2C2 – Thermal Spray on Reinforced Concrete and NACE STG 01 – Reinforced Concrete. He also participates in various other subcommittees and task groups where he contributes his expertise and extensive experience.
Jorge is a frequent lecturer at industry venues and universities and is a regular speaker at the World of Concrete where he delivers seminars on repair and protection of concrete structures damaged by corrosion of the reinforcing steel.
Specialized Engineering Services for Corrosion
STRUCTURAL TECHNOLOGIES supports both our in-house and industry partners in condition assessment by performing a variety of evaluations to determine the extent of corrosion related damages. We draw upon the experience of our corrosion experts to interpret the data and ascertain the level of deterioration of a structure. In addition we evaluate the longevity of the structure based on its current condition and potential extension of its service life based on repair and/or installation of corrosion mitigation systems.
Assessment Services Include:
- Comprehensive condition and/or corrosion assessments
- Corrosion damage surveys
- Corrosion rate analysis
- Concrete contamination, including chloride and carbonation.
- Concrete resistivity
- Diagnostic services
- Time to failure / chloride, carbonation modeling
