Product Introduction

ASTM A588 Grade B (A588 Gr50, Corten B) corrosion resistant steel is premium weather resistant structural steel. Its special chemical composition accelerates the formation of a tight, self-adhering protective rust patina when exposed to outdoor weather conditions, eliminating the need for anti-rust painting for long-term outdoor service.
