Established in 1997, we are a leading supply chain industry company integrating carbon steel, coated steel, stainless steel, and other metal products. With a registered capital of 100 million yuan and total assets of 1.2 billion yuan, we have grown into a powerhouse in the Chinese metallurgical sector.
Covering 15,000 square meters, our facility houses 900+ employees, including 100+ senior managers and technical experts. We possess complete production lines for coking, sintering, steelmaking, and steel rolling, ensuring modern, systematic steel production technology.
Operating through 4 large outlets (Tianjin, Wuxi, Binzhou, Liaocheng), we maintain year-round inventory. Our products reach markets in the Middle East, Europe, America, and Asia, catering to aerospace, marine engineering, and nuclear power industries.
The Carbon Steel Coil 140mm specification represents a critical segment in the narrow strip steel market. As a specialized manufacturer, we observe that the global industrial demand for 140mm width coils is surging, particularly in precision engineering and automotive component manufacturing. These narrow-width coils offer unparalleled efficiency for stamping and roll-forming processes, reducing material waste in the production of brackets, hinges, and structural reinforcements.
In the current global commercial landscape, the shift towards high-strength, low-alloy (HSLA) steel is prominent. Our factory produces grades ranging from Q195 to Q355, ensuring that every 140mm coil meets the specific tensile and yield requirements of diverse international standards (ASTM, DIN, JIS). The 140mm width is specifically favored by manufacturers in Southeast Asia and the Middle East for cable tray production and light-gauge steel framing (LGSF).
Technological Evolution: The industry is moving toward "Smart Steel." At Shandong Tezhong, we integrate AI-driven quality monitoring to ensure the thickness tolerance of our 140mm coils is kept within microns. This precision is vital for high-speed automated production lines where even the slightest deviation can cause machine downtime. Furthermore, the global trend toward green manufacturing has pushed us to optimize our coking and sintering processes to reduce carbon emissions, making our steel a more sustainable choice for eco-conscious procurement teams.
Procurement Needs: Global enterprises are no longer just looking for "low cost"; they are seeking "supply chain resilience." By maintaining four strategic outlets across China, we mitigate logistical risks, ensuring that our 140mm carbon steel coils can be shipped via Tianjin or Qingdao ports with minimal lead time. Our ISO9001 certification and rank as the 2nd best enterprise technology center in China provide the authoritative trust required by large-scale industrial buyers.
Our team provides strategic guidance for technological development. With 27 years in the industry, our experts possess deep metallurgical knowledge to customize chemical compositions for specific industrial applications.
Including metallurgical, mechanical, and electrical engineers, they optimize the production process to ensure stability and high yield, particularly for specialized widths like 140mm.
Ranking 2nd among 575 national centers, our R&D focus is on high-performance alloys and corrosion-resistant coatings, ensuring our products stay at the forefront of market needs.
From raw material inspection to final shipment, our QC personnel implement a rigorous monitoring system. We were among the first in the industry to pass ISO9001 certification.
We hold the #1 domestic market share in 21 categories of steel products, including railway steel, construction steel, and coinage pure iron. This dominance translates to better pricing and reliability for our international partners.
Our 140mm carbon steel coils are widely used for stamping automotive parts. In European markets, high-tensile grades are preferred for safety components, whereas in Asia, cost-effective Q235 grades are utilized for body reinforcements.
For the Middle East, our galvanized and prepainted coils provide essential corrosion resistance for roofing and wall panels. The 140mm width is specifically optimized for automated roll-forming machines used in rapid housing projects.
In the American and Australian mining sectors, our heavy-duty carbon steel sheets and pipes support the construction of robust extraction equipment and transportation pipelines.
