All ECP steel piers come standard with galvanized steel pier sections. These pier sections are designed to provide years of support in event he harshest sub surface environments while providing excellent structural support.
Earth Contact Products offers pier sections in a variety of sizes depending on specific needs and the piering system specified. The pier pipe for the ECP Model 300 and 350 steel piers is supplied with a quadruple coat in-line process of corrosion protection as standard. This corrosion protection process consists of heating the clean steel pier sections to high heat and placing it in a bath of molten zinc. This process creates an extremely hard and uniform layer of pure zinc. Then the zinc is rendered inert against oxidation by a passivation process using a precisely controlled chromate bath. This passivation forms a complex layer of zinc chromate compounds that halts interaction of oxygen and water with the zinc to prevent premature corrosion.
The quadruple layer corrosion protection process produces a strong and durable coating on the pier section that is smooth and shiny. The interior of the pipe is also coated with zinc. Independent laboratory salt spray testing of this tubing compared with standard galvanized schedule 40 pipe showed the in-line corrosion protection lasted up to 33% longer.
