Product introduction

Standard specification for high-strength low-alloy structural steel, up to 50 ksi [345 MPa] minimum yield point, with atmospheric corrosion resistance.
The required ASTM G101 Corrosion Resistance Index must be ≥ 6.0. In addition to the typical application in welded bridges and buildings, the specification is also commonly used in passenger rail cars.

The specifications:
Thickness: 3mm--150mm
Width: 30mm--4000mm
Length: 1000mm--12000mm
Standard: ASTM EN10025 JIS GB
