Corrosion Protection
Coating quality is guaranteed and full traceability are all standard in ESC QC Documentation. Handling and protective packing are also critical to any corrosion protection system. ESC's Quality Control Engineers are dedicated to preventing any product damage at any stage delivering to your site.
Implementing Corrosion Protection can increase the design life, lower the pile specification because thicknesses losses are minimized, improve aesthetics and lower the maintenance period once installed. This section showcases the 4 main corrosion protection methods that are an option to our customers.
Coal Tar Epoxy Coating
Coal Tar Epoxy Coatings are the most commonly used steel sheet piles for corrosion protection due to their low cost and high resistance to exposure to seawater, petroleum and chemicals. ESC can provide competitive solutions to meet project requirements.
ESC uses internationally recognized brands and specifications of epoxy coal tar paint that meet the specifications of projects worldwide. Sandblasting according to SSPC10 or NACE No 2 standards is the standard for ESC products. ESC's SSPC certified paint inspectors ensure the quality of the coating of the final product at all stages of preparation, application and testing. The standard color for these coatings is black.
Glass Flake Epoxy Coating
Glass Flake Epoxy Coatings are ideal for applications where impact and high abrasion environments are expected. ESC applies strict quality controls and careful packaging to ensure that the coating is in perfect condition when the product arrives at your site.
Hot Dip Galvanization
The Hot-Dip Galvanizing process involves coating the steel sheet piles with a layer of zinc. This is achieved by immersing the steel sheet piles in a bath of hot molten zinc. It is considered an alternative form of corrosion protection as the use of paint systems and produces a glossy surface aesthetic. These have the experience and contacts to use such systems to it's sheet piles.
Cathodic Protection
Cathodic Protection includes a sacrificial element that electrically connects only preferentially to the structural steel corroded sheet piling. It can be used as an additional form of corrosion protection on top of the corrosion protection coating system. These can offer it's experience in the design, specifications and integration of a cathodic protection system for submerged sheet piles.
Duplex Coating System
Duplex Coatings consist of a combination of hot-dip galvanizing and traditional epoxy coating systems. Although these are not standard applications, this may be necessary for special projects and ESC can offer such solutions.
