Steel Pipes KOXY is a leading manufacturer and global supplier of high-quality steel pipes, engineered to meet the rigorous demands of diverse industries and international standards. With decades of expertise, we provide not just products, but reliable, certified piping solutions that ensure project integrity, reduce long-term costs, and streamline your supply chain.
Certified under ISO 9001, ISO 14001, and ISO 45001, we enforce standardized management from raw materials to production. Products hold "China AAAAA Quality Credit Enterprise" and "Quality Pioneer" certifications. Our hot-dip galvanized (HDG) pipes are listed in China’s National Fire Equipment Catalog, featuring 3–5× enhanced corrosion resistance via ISO-compliant HDG processes. Widely used in firefighting and electrical sectors.
● Compliance: ASTM A53 (U.S.), BS 1387 (UK), GB/T 3091 (China).
● Not suitable for acidic/alkaline/saline environments.
● Sizes: DN15–300mm round pipes; HDG square/rectangular pipes and profiles.
● Applications: Water, sewage, gas, firefighting, air, oil, steam systems, and mechanical structures.
Using Japanese TPS lean management, we optimize efficiency and cost. Patented innovations like "Galvanized Pipe Deformation Reset Device" and "Seal-Testing Device" boost product yield to >99.8%. Automated laser-welded high-frequency pipes show 20% stronger seams than conventional methods, suitable for skyscrapers and bridges.
Four product lines: HDG round pipes, seamless pipes, square/rectangular pipes, and galvanized profiles (DN15–DN600). Serving 20+ sectors including construction, petrochemicals, and steel structures (50%+ market share in South China fire pipes).
Custom options: lengths (≤12m), materials (e.g., Q355B alloy steel), and coatings (e.g., epoxy powder).
Example: Salt-resistant HDG pipes for a Southeast Asian sea-crossing bridge project (25+ year lifespan).
Key Application Scenarios ● Oil, Gas, and Petrochemical Industries: Ideal for onshore/offshore pipelines, process plant piping, casing, and structural applications, meeting the high-strength and safety standards of the energy sector.
● Construction and Infrastructure: Used for structural supports, scaffolding, potable water supply lines, and drainage systems in commercial, residential, and public infrastructure projects.
● Water Transmission and Utilities: A reliable choice for municipal water and wastewater networks, irrigation systems, and fire protection sprinkler mains.
Industrial and Manufacturing Plants: Suitable for compressed air lines, material conveyance, industrial processing, and equipment frameworks across various manufacturing sectors.
● Power Generation and Mining: Employed in plant piping, coal slurry transportation, mine dewatering, and ventilation systems where durability is critical.

FAQ As a global supply chain service provider with operations in over 30 countries and regions, our comprehensive product range—encompassing pipes, fittings, valves, and fire-fighting equipment—has obtained ISO international quality certification and complies with multiple regional standards, including CE, UL, and SASO. These products have been successfully implemented in various international scenarios, such as infrastructure projects in Southeast Asia, commercial complexes in the Middle East, and fire renovation projects in Eastern Europe. For both regular procurement and cross-border customization, we offer an integrated solution that spans product selection, customs clearance, and logistics management.
Absolutely. For overseas customization requests, our engineering team collaborates directly with international blueprints and technical specifications to provide multi-standard compatible designs, including wall thickness conversion and pressure grade adaptation. Additionally, we provide:
- Third-party testing reports for pre-production samples
- Packaging labels compliant with the destination country's regulations
- Bilingual technical documentation and compliance certificates to ensure smooth local acceptance
We enforce a global quality control system that surpasses national standards. Each batch undergoes rigorous testing, including raw material composition analysis, pressure burst tests, and salt spray corrosion resistance evaluations, accompanied by bilingual (Chinese-English) quality inspection reports. Based on project location requirements, we can furnish free certification documents for target markets, such as CE (European Union), UL (United States), and BIS (India). Furthermore, we support on-site inspections and remote video audits to ensure full transparency in the quality control process.
The standard delivery cycle for overseas orders ranges from 25 to 45 working days. We offer diverse shipping options, including full container loads, less-than-container loads, and air freight express services. Our international logistics network covers major ports and airports worldwide. To facilitate swift customs clearance, we provide essential international certification documents, such as certificates of origin and commercial invoices. Leveraging our bonded warehouses in Hong Kong and Shenzhen, select Southeast Asian orders can be expedited with delivery within 7 to 10 days.
We deliver cross-border after-sales support through a 7x12-hour customer service model (email/WhatsApp/phone) with a guaranteed response time of two hours and a resolution proposal within 24 hours. For warranty-related quality issues, we cover basic shipping costs from Chinese ports or airports to the destination port. Additionally, we provide remote technical guidance, bilingual materials, and coordinate online support with engineers when necessary.
Absolutely. As a one-stop supplier, we specialize in customizing products to match your unique project needs:
Customizable parameters: Pipe diameter (DN15-DN2000), valve pressure rating (PN10-PN400), material (304/316 stainless steel, carbon steel, galvanized steel);
Fire system customization: We collaborate with your engineers to design integrated systems (e.g., high-rise building fire pipelines + matching valves + sprinklers) and provide 2D/3D drawings for confirmation before production.
Sample production is available for testing prior to mass orders.
