Zinc Plating at ECO Finishing

ECO Finishing provides Zinc Plating in Minneapolis that is compliant with ASTM-B-633 09. With over 60,000 sq ft of clean, well lit space, ECO Finishing has a streamlined plating process that complies with all EPA regulations regarding safety and waste treatment.

Zinc plating prevents oxidation and corrosion of the protected metal by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. ASTM-B-633 09 covers the requirements for electro-deposited zinc coatings applied to iron or steel articles to protect them from corrosion. It does not cover zinc-coated wire or sheets. High strength steels with a tensile strength greater than 1700 Mpa shall not be plated.

ECO Finishing provides Zinc Plating services to a wide range of industries including automotive, aerospace, medical, military and manufacturers of industrial and consumer products. We do both rack and barrel plating in clear, yellow, olive drab or black finishes, and plate parts up to 13 feet in length for both low and high volume orders. ECO also provides Zinc Phosphate coatings.

The service life of Zinc plating in relation to the thickness and types of environment to which it is exposed is as follows:

EnvironmentMean Corrosion Rust (Zinc Only)
Industrial5.6mm / Year
Urban or marine1.5mm / Year
Suburban1.3mm / Year
Rural0.8mm / Year

The service life of zinc coatings is tied to the conditions of its environment or the wear or abrasions it is subjected to.

  • SC1 - Mild conditions with exposure to dry indoor air and minimum wear and abrasion
