Metalized Cathodic Protection (MCP) Systems for Concrete
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.
Metalized Protective Coatings for Steel and Metals
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 provides installation support to qualified contractors which includes equipment, materials, expert technical field support, as well as quality assurance / quality control.
When teamed with our specialty contracting companies – STRUCTURAL TECHNOLOGIES provides owners and operators a turnkey investigate-design-build approach from a single source of accountability.
