Company Profile
CNB New Materials (Tianjin) Co., Ltd. - Commitment and Brilliance, Forged in Steel
Founded in 2017 and headquartered in the Tianjin Free Trade Zone (Airport Economic Zone), CNB New Materials combines the resource strength of a state-owned enterprise with the agility of market-driven operations. Our business spans steel raw materials, deep-processed products (including stamping parts), automotive components, and coke. We have rapidly grown into a trusted and professional steel supplier across North China and beyond.
A Diversified Product Portfolio Serving High-End Manufacturing
We offer a full range of flat steel and advanced materials: Cold-rolled, galvanized, Galvalume®/aluzinc, Zn-Al-Mg (ZAM) coated, aluminized, pre-painted (color-coated), stainless steel, aluminum, bimetal composite clad plates, and VCM laminated steel. For the photovoltaic sector, we deliver a one-stop solution integrating highly corrosion-resistant ZAM steel, PV mounting profiles, spiral ground piles, and filmed steel with up to 90% reflectivity. Driven by continuous innovation, CNB was among the first to mass-produce aluzinc coatings up to 275 G/M², ZM coatings up to 600 G/M², and aluminized coatings up to 400 G/M². We also pioneered large-diameter aluminized steel pipes and 2.0 mm-thick VCM laminated steel. Many of our coated products exceed 4, 000 hours in salt spray testing-redefining corrosion-resistance benchmarks with verifiable performance.
Full-Chain Strengths That Create Irreplaceable Value
CNB goes well beyond material supply. We maintain daily stockpiles of tens of thousands of metric tons across key categories like galvanized, ZAM, and cold-rolled steel, ensuring fast response and reliable delivery. On the technical side, we hold absolute advantages in automotive-grade high-strength steel (tensile strength above 900 MPa), ultra-thin deep-drawing cold-rolled coil (below 0.3 mm), heavy-gauge hot-DIP galvanized coil (up to 8.0 mm), and extra-wide pre-painted coil (up to 1, 650 mm). In parallel, we integrate global shipping and freight-forwarding resources to offer price-lock mechanisms and supply chain financing support-effectively easing capital pressure and creating a full value chain from material to service.
Proven by Global Trust, Powered by Brand Strength
Through rigorous quality control and on-time delivery, CNB has become a fixed raw-material supplier to renowned international companies including Panasonic, Toyota, Honda, IKEA, and Komatsu. Our materials have also been used in landmark projects such as the 2022 FIFA World Cup stadiums in Qatar. As a core agent of China National Building Material Group (CNBM), we operate with a serious in-house testing team and can provide certificates like CBAM for exports to Europe. Our reliable quality and professional service have earned broad recognition from clients both at home and abroad.
Looking Ahead - Connecting Markets, Building Excellence
Moving forward, CNB will continue to leverage its advantages in raw materials and manufacturing equipment, expanding into high-precision deep processing and stamped components while elevating service capabilities. We remain dedicated to our philosophy of "Commitment and Brilliance, Forged in Steel, " and aim to be a new-materials ecosystem builder that connects global markets and creates the best solutions together with our partners.

FAQ
- What is the difference between L245 and X52 pipeline steel?
- L245 is a lower-strength pipeline steel with minimum yield strength of 245 MPa, suitable for low-pressure gas and water transmission. X52 offers higher strength at 360 MPa minimum yield, allowing thinner wall pipe design or higher operating pressures, making it the standard for long-distance oil and gas trunk lines.
- Do you provide hot rolled steel plates with 3.2 certification for pressure vessels?
- Yes, our Q345R and A516 GR70 hot rolled steel plates can be supplied with EN 10204 3.2 certification witnessed by third-party inspectors including Lloyd's Register, Bureau Veritas. Full ultrasonic testing per ASTM A435 is standard for pressure vessel grades.
- How long does weathering steel take to form its protective rust patina?
- SPA-H and Corten hot rolled steel typically develops a stable protective patina within 6-18 months of outdoor exposure, depending on wet/dry cycling. Once stabilized, the patina protects the steel indefinitely without painting. The weathering process can be accelerated with pre-treatment solutions if an immediate aesthetic is required.
