● Specification: Outer diameter (OD) 1/2" - 24" (12.7mm - 609.6mm), wall thickness (WT) 0.8mm - 12mm, length 3m - 12m (customizable for special lengths), coil weight 1-5 tons/coil, perfectly matching the size requirements of various construction pipelines and structural components.
● Process: Advanced ERW (Electric Resistance Welding) technology, with high-frequency induction welding process that ensures uniform welds, no air holes or cracks, and weld strength reaching 95% of the base metal; post-welding annealing treatment to eliminate internal stress and improve product stability.
● Standard: Complies with ASTM A36/ASTM A572, API 5L (for oil and gas supporting), EN 10217 (European standard), GB/T 3091 (Chinese standard), fully meeting the import requirements of different regions.
● Surface Treatment: High-quality hot dip galvanizing process, zinc coating thickness 65-120μm (customizable according to corrosion resistance requirements), coating adhesion ≥35MPa (tested by pull-off method), surface smooth and uniform without peeling, effectively isolating air and moisture.
YTDR Group has a professional R&D and production team, with strong customization capabilities to meet the personalized needs of different customers. The customizable dimensions include:
● Specification Customization: Provide non-standard sizes such as special outer diameter (＞24"), special wall thickness (＞12mm), and special length (＞12m), and can adjust parameters according to customer drawings and project requirements.
● Surface Treatment Customization: In addition to standard hot dip galvanizing, it can also provide 3PE/3PP anti-corrosion coating, epoxy resin coating, and other customized coating services to meet the corrosion resistance requirements of different environments (such as chemical plants, desalination plants).
● Connection Method Customization: Support thread connection (NPT/BSP), flange connection (ANSI/EN standard),坡口 processing (bevel angle 30°-45°), and other connection methods, matching the installation habits and project requirements of customers in different regions.
● Packaging Customization: Adopt export-standard packaging, including wooden cases, steel pallets, and anti-rust film wrapping, which can be customized according to customer requirements (such as fumigation-free packaging for European markets) to ensure that the products are not damaged during sea transportation.
Our ERW carbon iron steel coils hold a complete set of international certifications that are highly recognized by global B-end clients:
● API 5L (qualified for oil and gas pipeline auxiliary structural components) | CE Certification (compliant with EU construction product regulations, free circulation in EU market)
● ISO 9001 Quality Management System Certification (full-process quality control from raw material smelting to finished product delivery)
● SGS/BV Third-Party Inspection Report (customizable inspection standards according to client requirements)
● Certificate of Origin (CO) —— supporting preferential tariff applications for import clients.
1. Supply Chain Capabilities
● Production Capacity: We have 3 advanced ERW steel pipe production lines and 2 hot dip galvanizing production lines, with an annual production capacity of 50,000 tons. For standard size products, the lead time is 7-15 days; for bulk orders (≥1000 tons) or customized products, the lead time can be negotiated according to the order quantity and customization requirements, ensuring that customers can receive goods on time.
● Logistics Support: We support multiple trade terms such as FOB/CIF/EXW, and have long-term cooperative relationships with top international shipping companies (Maersk/CMA CGM/Hapag-Lloyd). We provide door-to-door delivery services for global customers, covering more than 100 countries and regions, and can customize the most cost-effective logistics plan according to the customer's location and order quantity, reducing logistics costs and time.
● Quality Inspection: We implement a strict three-level quality inspection system: raw material inspection (100% inspection of material certificates and mechanical properties), in-process inspection (weld quality, dimensional accuracy inspection), and finished product inspection (hydrostatic pressure test, corrosion resistance test). 100% inspection before shipment, and third-party inspection (SGS/BV) can be arranged at the request of customers. We provide a12-month quality warranty, and if there is any quality problem within the warranty period, we will provide free replacement or maintenance services.
Tailored to the diverse needs of infrastructure sectors, our ASTM A36/A572 Grade ERW Carbon Iron Steel Coil has been widely applied in:
1. Building Structural Support
Suitable for the support structure of high-rise buildings, bridges, workshops, and other projects. The high strength and good toughness of Grade A36/A572 steel can bear large loads, and the hot dip galvanizing coating can resist outdoor corrosion. Our pipes have been supplied to 20+ projects in the Middle East/Europe/North America (case studies available), such as the Dubai Marina high-rise residential project and the Berlin Industrial Park workshop construction project.
2. Water Supply and Drainage Pipelines
Widely used in urban water supply pipelines, municipal drainage pipelines, and building internal water supply and drainage systems. The excellent corrosion resistance of the hot dip galvanized coating can avoid pipe corrosion caused by water quality, and the high pressure bearing capacity ensures the stable operation of the pipeline. Our pipes have been supplied to 20+ projects in the Middle East/Europe/North America (case studies available), including the Riyadh Urban Water Supply Pipeline Renovation Project and the Toronto Municipal Drainage System Project.
