Shandong Tezhong Materials Co., Ltd. is a leading supply chain powerhouse in the global metal industry. With a registered capital of 100 million yuan and total assets reaching 1.2 billion yuan, we have established ourselves as a benchmark for quality and reliability. Our facility spans 15,000 square meters, housing integrated production lines that cover the entire steel lifecycle—from coking and sintering to advanced steelmaking and precision rolling.
As a specialized China Q235b Carbon Steel Coils Factory, we employ over 900 dedicated professionals, including 100+ senior technical experts. Since our inception in 1997, our mission has been to bridge the gap between high-end Chinese manufacturing and the evolving needs of global infrastructure. We don't just sell steel; we provide the foundational material for the world's most ambitious engineering projects.
Q235b is the "backbone" of modern construction. Globally, mild carbon steel accounts for nearly 50% of the total steel consumption. Its excellent weldability, plasticity, and moderate strength make it the primary choice for structural components in the Middle East, Southeast Asia, and South America.
The industry is moving towards "High-Performance Mild Steel." While Q235b remains a standard, the focus is shifting to precision surface treatments and tighter tolerance controls. Our factory is leading this trend by integrating AI-monitored rolling processes to ensure consistency in every coil.
International buyers are increasingly looking for "Reliable Supply Chain Partners" rather than just suppliers. With global logistics volatility, our 4 major distribution hubs in Tianjin, Wuxi, Binzhou, and Liaocheng provide the strategic stock necessary to meet urgent procurement demands.
Q235b steel is defined by its yield point of 235 MPa. The "b" grade signifies a specific level of deoxidation and impact testing quality, making it superior to basic Q235 for structural reliability. In the context of international standards, Q235b is often compared to ASTM A36 (USA), SS400 (Japan), and S235JR (Europe). Its chemical composition, balanced with carbon, manganese, and silicon, provides the perfect equilibrium between cost and performance.
Our carbon steel coils are utilized in diverse localized environments:
Engaged in the steel industry since 1997. We were the first to pass ISO9001 certification in our region, ensuring every batch meets international benchmarks.
Our technology center ranks 2nd among 575 national centers in China. We lead the domestic market share in 21 categories including railway and axle steel.
Strategic locations near major ports allow us to offer faster transportation and lower freight costs, with a comprehensive annual capacity of 1.5 million tons.
We provide full-spectrum service from technical consultation to after-sales support, ensuring complete specifications and competitive pricing.
With decades of experience, our experts provide strategic guidance for metallurgical innovations and process optimization.
Metallurgical, mechanical, and electrical engineers collaborate to ensure the stability of every production cycle.
Focused on developing new steel grades and strictly monitoring quality from raw material to finished product delivery.
