Premium Material Grades & Core Mechanical Properties
We select high-quality raw structural steels strictly in accordance with global material benchmarks, ensuring each grade delivers targeted performance to match different load-bearing and application scenarios, with stable chemical composition and superior mechanical indicators as follows:
ASTM A36: As a classic carbon structural steel under American ASTM standards, it boasts universal applicability, excellent ductility and weldability, with reliable tensile and yield strength. This grade is ideal for general construction projects, featuring easy processing and strong adaptability to routine welding, cutting and forming operations, serving as a mainstream choice for conventional load-bearing frameworks.
S235jr: A representative general-purpose carbon structural steel under European EN standards, it offers a minimum yield strength of 235MPa, paired with outstanding toughness and cold-forming performance. With stable quality and cost efficiency, it is widely applicable for light-to-medium load structural parts, auxiliary building components and non-critical industrial supports, fully meeting daily engineering construction needs.
ASTM A572: A high-strength low-alloy structural steel grade, it features enhanced strength-to-weight ratio, excellent fatigue resistance and impact toughness, with higher yield and tensile strength than ordinary carbon steels. It is specially designed for medium-to-heavy load, long-span and high-stress structural projects, effectively reducing structural weight while improving overall bearing capacity and durability.
Q345: A high-strength low-alloy structural steel under Chinese national standards, it delivers balanced strength and ductility, good low-temperature toughness and weldability. With a minimum yield strength of 345MPa, it adapts to complex application environments, suitable for industrial workshops, high-rise building skeletons and heavy-duty supporting structures requiring superior load-bearing performance.
