North Steel Manufacturing Co., Ltd. was founded in 1989, boasting 36 years of profound experience in the steel industry. It is an integrated manufacturing enterprise integrating R&D, production, foreign trade sales and technical services of steel products. Focusing on the R&D and production of high-end steel pipes and supporting products, the company has an annual production capacity of 150,000 tons, covering 10 core categories. Its main products include carbon steel pipes (Seamless SMLS/ Electric Resistance Welded ERW/ Longitudinal Submerged Arc Welded LSAW/ Spiral Submerged Arc Welded SSAW), stainless steel pipes, galvanized steel pipes, alloy steel pipes, oil country tubular goods (OCTG) and various pipe fittings. We accurately serve six core industries including oil & gas, water supply, construction, offshore engineering, power energy and mechanical engineering, and deeply cultivate mainstream global markets such as Southeast Asia, Europe, America and the Middle East.

✅ Strong Production Capacity & Advanced EquipmentEquipped with standardized production bases, we have full-process hot rolling and cold rolling production lines as well as professional HDG hot-dip galvanizing production lines, enabling precise mass production of steel pipes and profiles in various specifications. We have set up an exclusive physical and chemical testing center, and built a closed-loop quality inspection system covering "raw material incoming inspection - rolling processing - finished product delivery", resolutely eliminating non-conforming products from delivery, and comprehensively ensuring stable product quality and efficient delivery.

✅ Authoritative International CertificationsThe company has successfully obtained ISO9001 Quality Management System Certification and ISO14001 Environmental Management System Certification. Core products fully comply with API 5L (line pipe steel) and ASTM international standards, meeting the stringent import access requirements of Southeast Asia, Europe, America, the Middle East and other regions. Adhering to ISO 9001 Quality Management System in production, our products have been certified by authoritative third-party inspection institutions including SGS, BV, TUV, ABS, LR, GL, DNV, CCS, RINA and RS.

✅ Core Product SystemFocusing on core categories highly adapted to foreign trade needs, our products feature weather resistance, corrosion resistance and suitability for complex working conditions, covering multiple application scenarios:
Steel Pipe Series: Seamless steel pipes, welded steel pipes, stainless steel pipes and HDG hot-dip galvanized steel pipes. With excellent corrosion and weather resistance, they are suitable for harsh environments such as high temperature, high humidity and high salt spray, meeting core needs of oil & gas transmission, municipal water supply and drainage, outdoor infrastructure and offshore engineering.
Special Tubular Goods: Oil country tubular goods (OCTG) and alloy steel pipes, adapted to professional scenarios such as energy exploitation and high-end equipment manufacturing, with quality conforming to international high-end standards.
Profile Series: Angle steel, channel steel and I-beam, with complete specifications and supporting non-standard customization, widely used in steel structure workshop construction, bridge building, mechanical equipment manufacturing and other fields.

✅ Exclusive Foreign Trade ServicesTailor-made for global cross-border procurement, we provide worry-free, efficient and cost-saving one-stop services:
Port Advantages: We have in-depth strategic cooperation with three core foreign trade ports including Tianjin Port, Shanghai Port and Nansha Port, with mature and stable logistics channels and sufficient space guarantee. We can arrange shipment quickly, greatly shortening the global delivery cycle.
In-depth Development of Key Markets: Focusing on Southeast Asia, Europe, America and the Middle East markets, we are familiar with local import policies, customs clearance rules, tariff requirements and logistics processes. We can fully assist customers in customs clearance and avoid potential risks of cross-border procurement.
Full-process Dedicated Service: From pre-sales inquiry and quotation, accurate confirmation of technical parameters, to real-time synchronization of production progress in mid-sales, and full control of logistics and customs declaration in after-sales, we provide one-on-one efficient docking with dedicated personnel. We support customized production of specifications and materials to accurately meet customers' personalized procurement needs.

✅ Corporate PhilosophyWe consolidate the foundation of cooperation with quality and enhance the value of cooperation with services. Adhering to the core principles of "Integrity, Efficiency and Win-Win", we aim to establish long-term and stable strategic cooperative relations with global customers and create industry value together.
