Luoyang Guorun New Material Technology Co., Ltd. produces large‑diameter corrugated steel pipe designed for high‑load culvert, storm‑water drainage and other infrastructure uses. The pipe is fabricated from hot‑dip galvanized carbon steel or structural steel grades S235 and S275, and it conforms to the Chinese standard CJ/T189‑2007. The product range covers diameters from 300 mm up to 1800 mm, with wall thicknesses between 2.5 mm and 6 mm, making it suitable for a variety of municipal and agricultural projects.
Typical pipe variants include PE‑coated interiors for water supply, as well as plain galvanized steel for drainage applications. The corrugated profile provides superior structural rigidity while allowing efficient flow, a feature valued in highway culverts and irrigation channels. Standard manufacturing tolerances for diameter are ±3 mm and wall thickness tolerance is ±0.2 mm, matching industry expectations for large‑diameter steel pipe.
Buyers are usually public‑works agencies, construction contractors or utility companies that require durable, long‑lasting drainage solutions. The listing does not disclose MOQ, price per metric ton or specific lead‑time, so these details must be obtained directly from the supplier. When negotiating, confirm the corrosion‑protection coating thickness, connection method and any additional auxiliary tools required for installation.

Luoyang Guorun New Material Technology Co., Ltd. is situated in Airport Industrial Park, Luoyang, Henan 471132, China. The company holds a harbour‑level trust tier but currently shows a 0.00 response rate and no recorded average response time, indicating that initial contact may need to be followed up promptly.
The supplier focuses on manufacturing corrugated steel pipe and related PE‑coated products for drainage, water supply and agricultural engineering applications. Its catalogue mentions a broad selection of diameters and connection options, yet it does not publish MOQ, pricing or exact lead‑time, so prospective importers should request those figures directly from the company.
Large diameter corrugated steel pipes are heavy-walled metal tubes with annular corrugated profiles, designed for high-load culvert, stormwater drainage, and infrastructure applications. Available in diameters typically ranging from 300mm to over 3000mm, these pipes offer superior structural rigidity and flow efficiency. Widely sourced for municipal drainage projects, highway culverts, and irrigation systems, they are priced per metric ton with costs varying by wall thickness, galvanization grade, and coating specifications.

Importers should first verify the steel grade certificates and zinc coating thickness reports to ensure the pipe meets the required durability standards. Request a recent batch test report that references CJ/T189‑2007 compliance, and ask the supplier to provide photographs of the corrugated profile for visual confirmation.
Logistics discussions should clarify the incoterm - FOB Luoyang or CIF Shanghai are common - and the expected lead‑time, which can vary with pipe diameter and coating options. Payment terms are usually 30 % T/T in advance with the balance against shipping documents, but these can be negotiated based on order volume and buyer credit history.
Arrange for a third‑party inspection at the factory or upon arrival to check dimensions, wall thickness, coating thickness and weld quality. Non‑destructive testing such as ultrasonic thickness measurement is recommended for large‑diameter sections. Ensure the supplier supplies a full inspection certificate and a certificate of conformity before final acceptance.
