Polyaspartic coatings increase painting efficiency of shop-painted steel bridges

Covestro to present at World Steel Bridge Symposium

Pittsburgh, April 10, 2018 — Protective coatings have been used to mitigate corrosion of steel bridges for more than a century. For the last several decades, a three-coat system featuring zinc, epoxy and polyurethane layers has been utilized very successfully. However, economics and schedule impacts are driving more Departments of Transportation to apply all coatings in the shop for new steel bridges. This shifts the painting responsibility to steel fabricators, creating an additional revenue stream and possible scheduling complications.

The application of the conventional three-coat system in a shop setting is time and labor intensive. Two-coat polyaspartic coating systems have the capability to vastly improve efficiency in the painting process. Polyaspartic coatings offer a number of advantages, including increased painting productivity and reducing project costs, without sacrificing corrosion protection.

Polyaspartic Coatings: Reducing the Cost of Shop Painted Steel Bridges through Improving Painting Efficiency” will be the topic of a presentation at the World Steel Bridge Symposium. The presentation will take place on Friday, April 13 as part of the “Advanced Coating Systems” session beginning at 1:45 p.m. Ahren Olson, market manager of protective coatings at Covestro LLC, and Ronnie Medlock, vice president – engineering at High Steel Structures, will conduct the presentation.

The vast majority of polyaspartic coating applications in the steel bridge market have been for field maintenance painting. Olson and Medlock will discuss cost and throughput advantages of polyaspartic coatings specific to the shop painting of steel bridge structures, which can generate significant value for steel fabricators and bridge owners. They will also highlight a case study from the Maine Department of Transportation featuring a two-coat polyaspartic coating system for a new steel bridge.

Presented by the National Steel Bridge Alliance, World Steel Bridge Symposium takes place in Baltimore, April 11-13.
