A36/Q235/S235JR Carbon Steel Coil Description:
A36 is a low-carbon steel that contains trace amounts of manganese, phosphorus, sulfur, silicon, and other elements such as copper. It is known for its excellent weldability and high yield strength, making it the structural steel plate of choice for engineers. ASTM A36 steel plates are commonly manufactured into a variety of structural steel components. This grade is widely used in welded, bolted, or riveted constructions of bridges, buildings, and for general structural applications.
Due to its well-defined yield point, A36 carbon steel plates allow for the design of lighter-weight structures and equipment while maintaining good weldability. Industries such as construction, energy, heavy machinery, transportation, infrastructure, and mining frequently utilize A36 steel plates.
Similarly, Q235 and S235JR are also common low-carbon steel grades that comply with China’s GB standard and Europe’s EN standard, respectively. These steels exhibit excellent mechanical properties and are widely used in projects requiring reliability and strength. Regardless of the specific standard, these carbon steel materials are highly favored for their superior processing performance and cost-effectiveness.
