ASME SA588 / SA588M Grade C carbon and low-alloy high-strength steel sheets, designed for structural applications requiring high strength, excellent toughness, and superior atmospheric corrosion resistance.
These sheets are widely used in bridge construction, highway infrastructure, heavy engineering, and other structural projects where reliability and durability are critical.

Compared with ordinary structural steel, SA588 Grade C offers approximately 38% higher yield strength, allowing for lighter structures without compromising safety.
Case Study: Using SA588 Grade C steel in bridge construction reduces maintenance costs by 30% compared with mild steel, thanks to its natural atmospheric corrosion resistance.
Heat Treatment: N (Normalized), Q+T (Quenched & Tempered), TMCP (Thermo-Mechanical Control Process)
Testing & Certification: UT (Ultrasonic Testing), Charpy V-Notch, Z-Direction Test (Z15, Z25, Z35), Third-Party Test (e.g., SGS)
These options ensure that each coil meets project-specific requirements, from mechanical performance to surface finish.
