A709 Carbon Steel Coil
ASTM A709 Carbon Steel Coil is a specialized high-strength structural steel coil engineered for bridge construction, available in Gr 36, Gr 50, Gr 50W and low-temperature grades with tailored performance. It delivers excellent yield/tensile strength, outstanding fatigue and impact resistance, adapting to heavy load and outdoor bridge working conditions. Boasting superior weldability and formability for complex structural fabrication, it has precise dimensional tolerance and customizable thickness/width/length, serving as a core reliable material for professional bridge engineering applications.
