Tianjin Qingze Iron & Steel Trade Co., Ltd has established itself as a premier supplier in the global metals market. Headquartered in the industrial hub of Tianjin, the company leverages its proximity to one of the world's busiest ports to serve clients efficiently. At the core of our service offering is comprehensive custom metal processing, designed to meet the exact specifications of diverse industries. From construction and energy to transportation and heavy machinery, our processed materials form the backbone of critical infrastructure. A significant portion of our expertise lies in the precise fabrication of stainless steel components, ensuring superior corrosion resistance and structural integrity. We combine decades of industry experience with a massive in-stock inventory to provide solutions that are both high-quality and readily available. To understand our full operational philosophy and decade-long journey, we invite you to visit our ABOUT US page.

Our product range is meticulously curated to support every aspect of custom metal processing, ensuring that clients have access to the exact materials they need without costly delays. We stock a full spectrum of ferrous and non-ferrous metals in various forms, sizes, and grades. This comprehensive inventory is the foundation upon which our rapid processing and fabrication services are built. By maintaining deep stock levels, we eliminate the long lead times typically associated with importing specialty metals. For a detailed list of available stock and specifications, we encourage you to browse our PRODUCTS page.

Our inventory of stainless steel products is among the most comprehensive in the region, directly supporting our custom metal processing capabilities. We stock a full range of stainless steel pipes, round bars, and sheets in grades 304, 304L, 316, and 316L. These materials are available in various standard and non-standard sizes, ensuring that we can match almost any project blueprint. Surface finishes such as 2B, BA, No. 4, and mirror polish are readily available for aesthetic and functional requirements. Whether you need seamless pipes for high-pressure applications or welded pipes for structural support, our selection covers it all. This depth of inventory allows us to initiate custom metal processing orders immediately, drastically reducing downtime for our clients.

Galvanized carbon steel corrugated sheets are a staple in our inventory, prized for their durability and cost-effectiveness in large-scale construction. We supply these sheets in multiple thicknesses, coating weights (including Z275 and AZ150), and profile geometries. They are extensively used in roofing, siding, fencing, and agricultural building projects where weather resistance is paramount. The zinc coating provides a sacrificial barrier that protects the underlying carbon steel, offering decades of maintenance-free service. Our processing team can custom cut, bend, and punch these sheets to match specific building plans, minimizing on-site labor. This product also relates closely to advanced clad plate technologies, where multi-layer protection is engineered for extreme environments.

High-purity copper coils represent a critical product line for Tianjin Qingze, catering to the electrical, HVAC, and plumbing sectors. We specialize in copper coils with a purity of 99.9% or higher, ensuring excellent electrical and thermal conductivity. These coils are available in both soft (annealed) and hard (drawn) tempers to suit different forming and bending requirements. Typical applications include heat exchanger coils, refrigerant lines, water supply tubes, and electrical busbars. Our strict quality control ensures that every coil is free from scratches, pitting, and internal inconsistencies that could lead to failure. The consistent dimensional accuracy of our copper coils makes them ideal for high-speed, automated custom metal processing operations.

Beyond simply supplying raw materials, Tianjin Qingze adds immense value through our in-house custom metal processing and fabrication capabilities. We transform standard stock into ready-to-install components, saving our clients the hassle of managing multiple vendors. Our facility is equipped with advanced machinery capable of handling complex geometries and tight tolerances. We pride ourselves on our ability to execute both small-batch prototypes and large-scale production runs efficiently. This vertical integration is a key reason why global buyers trust us as a single-source partner for their metal requirements.

Our fabrication department is equipped with state-of-the-art laser cutting, plasma cutting, waterjet cutting, and CNC bending machinery. These tools allow us to execute the precise fabrication of stainless steel tanks, frames, pipes, and enclosures with exceptional accuracy. We handle a wide array of tasks, including beveling, threading, punching, and rolling, all under one roof. For clients with specialized needs, we also facilitate custom aluminum extrusions, providing lightweight profiles for architectural frameworks and industrial machinery. Our technicians carefully review every specification to ensure that the finished product meets exact dimensional and tolerance requirements. This comprehensive approach to custom metal processing significantly reduces project lead times and logistical complexity for our clients.

Quality assurance is deeply embedded in our operational workflow, from incoming raw material inspection to final product verification. Every batch of material undergoes rigorous chemical analysis and mechanical testing to confirm its grade and properties. Our processes strictly adhere to ASTM international standards, including A312, A269, A240, and A653, ensuring global acceptance. For specialized products like clad plate, we employ ultrasonic testing to verify 100% bond integrity between the base and cladding layers, guaranteeing flawless performance in demanding chemical and pressure applications. We routinely collaborate with third-party inspection agencies such as SGS, Bureau Veritas, and Intertek to provide unbiased quality validation. Full Mill Test Certificates (MTCs) and traceability documentation are provided with every shipment, offering complete transparency and peace of mind.

Our pricing and logistics models are engineered to provide maximum value and reliability to our international clientele. By combining direct mill purchasing power with an efficient logistics operation based at Tianjin Port, we offer a seamless export experience.
