High-Performance Equivalent Coatings Offer Superior Corrosion Resistance for Steel Framing

Read the "High-Performance Equivalent Coatings Offer Superior Corrosion Resistance for Steel Framing" White Paper by ClarkDietrich Building Systems.
 

SEVERAL INDUSTRIES, INCLUDING COLD-FORMED STEEL MANUFACTURERS, have developed high-performance “EQ” coatings that meet or exceed ASTM C645 requirements for corrosion resistance equivalent to traditional G40 protective coatings for nonstructural steel. These performance coatings, applied to zinc-coated steel coils pre- and post-reduction, utilize new corrosion-inhibiting and adhesion-enhancing formulas, which greatly improve the corrosion resistance of steel framing members.

 
The purpose of this paper is to define EQ coatings and how they differ from galvanized-only protective coatings specified for steel framing members by industry standards and codes. By doing this, we hope to position EQ coatings as a solid alternative to traditional protective coatings, offering superior corrosion resistance.
