Corrosion Protection

In keeping with the company’s mission to offer strong and durable products, Techno Metal Post has specially developed technologies using the principle of cathodic protection to ensure that even helical piles installed in corrosive soils are protected for the long term.

We offer hot-dip galvanized piers to provide long-term protection for foundation piles. In addition, Techno Metal Post can go one step further by offering alternatives to galvanizing, such as installing a cathodic protection system to ensure the integrity of the structure for any desired time period.

There are two products for the protection of helical pile foundations:

Ring Anode illustration.

Ring AnodesTM

Ring-shaped magnesium sacrificial anodes installed on the shaft of the pile. They provide one-time cathodic protection for small structures. Ring Anodes use the intrinsic electrochemical properties of metals. Since the magnesium anode is from material inferior to steel, it consumes itself, thereby releasing an electrical current that prevents the structure from corroding.

Spin Anode illustration.

Spin AnodesTM

Impressed current anodes that are screwed into the ground like piles. Therefore, they do not require excavation and are available in a variety of sizes depending on the current needed. Spin Anodes are made from alloys superior to steel and diffuse an electrical current produced by an external rectifier, thereby ensuring continuous protection of the buried steel structure.
