Case Studies
For over 20 years, USI has provided protective coatings and corrosion prevention products proven to protect our nations most critical infrastructure and industrial machinery. Along the way we have documented many projects and pain points we have been able to help our partners repair, protect and upgrade.

Metal Frame Repair
The Problem
A metal finishing company uses metal frames in the production of bands and superstructures for bridges and joists components that operate in extremely corrosive environments. They’re looking for a coating solution that extends the lifespan of these frames, reducing the need for frequent replacements.
The Substrate
Hot rolled steel
The Solution
Two coats of Maxon CRS were applied to the frames to effectively halt corrosion and protect these critical infrastructure components.
Products Used
Maxon CRS is a good stand alone coating that converts surface rust in the process. For longer lasting protection we suggest overcoating Maxon CRS with a more durable coating. Such as:
Resichem 501 – Where you need additional chemical and corrosion protection.
Resichem 555 – Where you need a flexible UV stable corrosion protective layer.
There are many other options for overcoating and each project has different exposures and needs, contact us today to see what is right for your project.
Metal Roof Repair on WWTP Building
The Problem
Metal roof repair: This WWTP was seeing extensive corrosion with their infrastructure. The corrosion was so advanced that it was causing the roof to leak. The facility was located near a nice-looking metro area, they were wanting to upgrade their image to keep their neighbors happy
The Substrate
Steel
The Solution
For this Metal roof repair, abrasive blasting was used to remove the rust. Maxon CRS acts as a corrosion retardant system that penetrates the steel, 20+ mils, so it goes in the metal not on the metal. A viscoelastic sealant was used to seal the joints along with Viscotaq EZ Wrap to create a flexible surface to stop leaking. To make everything look a pleasing two coats of Resichem 555 Resinox. Resinox was spray applied for future corrosion prevention.

Bridge Protection
The Problem
Weathered Steel also known as ASTM A-588, ASTM A-242, or Cor-Ten works well in many environments, and gives structures a rustic look. However, in areas with lots of salt water or low lying areas near rivers or heavy fog, there are some challenges and the structures continue to rust. This major Metropolitan Park authority was looking at extensive sand or grit blasting cost, heavy labor and environmental containment cost,and was in search of solution.
The Substrate
Steel
The Solution
Unconventional Solutions was able to minimize the surface preparation and lower the labor and preparation cost while still offering a long term solution. We recommended RESICHEM 555 Resinox for the entire structure. This flexible acrylic system offered tremendous cost savings and the cash tight metro park was able to do two bridges instead of just one with the surface preparation savings.
