ASTM A653 G90 Galvanized Steel Strip Specifications & B2B Sourcing Guide
In precision manufacturing and construction assembly, ASTM A653 G90 Galvanized Steel Strip represents the benchmark for structural durability and corrosion resistance. Sourcing high-quality steel strips requires a deep understanding of zinc coating weights, mechanical slitting tolerances, and grade classifications. This guide provides a B2B procurement roadmap for G90 galvanized coils and strips.
1. What is G90 Coating Weight?
The “G90” designation refers to the weight of the zinc coating applied to the steel surface. Under the ASTM A653 standard, G90 specifies a minimum average of 0.90 ounces of zinc per square foot (oz/ft²) across both sides of the sheet. In metric units, this equates to approximately 275 g/m².
