The Problem

A bridge at a large steel mill was experiencing severe corrosion they needed corrosion protection for their steel bridge. The traditional method of grit blasting to prepare the surface for new coating was deemed too costly by the company. They sought an effective, water-based solution that would minimize surface preparation costs without compromising on corrosion protection performance.

The Substrate

Steel: The bridge was constructed of steel, a material highly susceptible to corrosion if not adequately protected.

The Solution

Unconventional Solutions, Inc. (USI) provided a cost-effective and environmentally friendly solution to address needing corrosion protection for this steel bridge:

1. Surface Preparation:
   • The bridge was water blasted with a pressure of 3500-5000 psi. This method effectively removed rust and any loose coating without the high costs associated with grit blasting.
2. Application of Protective Coating:
   • Two coats of RESICHEM 555 Resinox were applied using brushes and rollers. This water-based, flexible acrylic encapsulated system offers excellent corrosion and UV resistance.
   • RESICHEM 555 Resinox can be applied at a thickness of 14-17 mils Dry Film Thickness (DFT) in a single coat, ensuring robust protection with minimal labor.

Additional Benefits

• Environmental Safety: RESICHEM 555 Resinox is safer for the environment compared to traditional solvent-based coatings, aligning with the company’s sustainability goals.
• Cost Reduction: The use of water blasting for surface preparation and the ease of application of the coating significantly reduced labor and material costs.
• Technical Support: USI’s technical field support ensured proper surface preparation and optimal coating performance, adding value to the company’s investment.

The Outcome The bridge at the steel mill was successfully protected from further corrosion using the RESICHEM 555 Resinox coating system. The solution not only provided excellent corrosion and UV resistance but also offered a cost-effective alternative to traditional grit blasting methods. The company was highly satisfied with the results and appreciated the technical support provided by USI.

18 years later: Fast forward 18 years, USI made a pit stop by this bridge. This coating is holding strong in a corrosive environment. Signs of wear and tear are mostly limited to the areas of the coating that had other signage over or under the coating itself.
