Construction & real estate›💡Electronic & Electrical›🍎Food & Beverages›🛋️Home furnishing & supplies›⚗️Industrial goods & chemical›🪨Minerals & metals›📦Miscellaneous›Threeway Steel Co., Ltd. supplies ERW structural steel pipe manufactured from carbon steel grades Q235 and Q345, with diameters spanning 219mm to 3000mm and wall thicknesses from 6mm to 25mm. These welded steel tubes conform to API 5L, ASTM A53, and GB/T 9711 standards, with additional grades including L360 available for load-bearing infrastructure applications. The pipes are produced in China and South Korea for global export to bridge, port, and marine engineering projects.
The material composition centres on low-alloy carbon steel, where Q235 offers a minimum yield strength of 235 MPa and Q345 provides 345 MPa, with both grades exhibiting suitable weldability and toughness for structural fabrication. ERW manufacturing produces a clean, consistent weld seam through electric resistance welding of hot-rolled coil, followed by sizing and straightening. Typical surface treatments include bare, oiled, or hot-dip galvanised finishes, the latter providing zinc coating weights of approximately 275-350 g/m² for atmospheric corrosion resistance in coastal environments.
Primary buyers include EPC contractors, bridge engineering consortia, and offshore platform fabricators sourcing longitudinally welded pipe for pile foundations, jacket legs, and truss structures. Common trade specifications require mill test certificates per EN 10204 3.1 or 3.2, with ultrasonic testing of the weld seam and hydrostatic pressure testing to verify integrity. Packaging is typically in bare bundles or woven-strapped bundles with metal end protectors, suitable for breakbulk or container shipment from Chinese mill yards.

Threeway Steel Co., Ltd. is headquartered at 22nd Floor, Royal Wing Tower, Long Champ, Changsha 410116, Hunan Province, China. The company's supplier tier is classified as 'imported' with a 'harbor' trust designation, indicating it has passed baseline verification as a registered export entity on the platform. The response rate is recorded at 0.00% with zero average response hours, which suggests the supplier has not yet engaged with buyer enquiries through the platform messaging system.
The listing focuses specifically on ERW structural steel pipe for major infrastructure, referencing supply from mills in both China and South Korea. The profile does not state annual production capacity, number of employees, revenue figures, or named client projects. No factory audit certifications, ISO accreditations, or specific export licence numbers are mentioned in the available data. Buyers should conduct independent due diligence on Threeway Steel Co., Ltd., including verification of mill relationships and inspection of sample mill test certificates, before committing to volume orders.
This ERW structural steel pipe is widely used in major infrastructure projects including bridges and offshore platforms. With diameters ranging from 219mm to 3000mm and wall thicknesses of 6mm to 25mm, these welded steel tubes meet standards such as API 5L, ASTM A53, and GB/T 9711. Grades include Q235, Q345, and L360, making them suitable for structural load-bearing applications in port construction, marine engineering, and highway projects. Commonly exported in bundled or bare bundle packaging from mills in China and South Korea, these pipes serve the global construction and infrastructure supply chain.

Before ordering from Threeway Steel Co., Ltd., buyers should verify that the supplier's mill partners hold valid API 5L and ASTM A53 licences, and request copies of recent mill test certificates to confirm compliance with the specified grade and mechanical properties. Independent third-party inspection during production is advisable given the zero platform response rate, which limits pre-order communication. Confirm the exact origin of manufacture, whether from Chinese or South Korean mills, as this affects import duties and origin certification requirements in the destination country.
Logistics arrangements should account for the substantial dimensions of large-diameter pipe, which may require open-top containers, flat-rack shipping, or breakbulk charter for diameters exceeding container limits. Typical Incoterms for Chinese steel exports are FOB Tianjin or Shanghai, though CIF terms may be negotiated. Payment structures commonly involve 30% advance payment with balance against copy of bill of lading, or confirmed letter of credit. Buyers must confirm lead time, which typically ranges from 30 to 60 days for standard grades but can extend for large-diameter or specialised coating requirements.
Quality checks on arrival should include dimensional verification (OD, wall thickness, length), visual inspection of weld seam and coating condition, and review of mill test certificates against actual heat markings. Destructive testing of coupon samples for tensile properties and Charpy impact may be specified in the purchase order. Documentation must be cross-checked for consistency across invoice, packing list, and mill certificate heat numbers. Any discrepancy in grade marking or certificate data should be escalated before acceptance, as structural steel for bridge applications carries significant liability and regulatory scrutiny.
