Shandong Zhongzheng Steel Pipe Manufacturing Co.,Ltd

Shandong Zhongzheng Steel Pipe Manufacturing Co., Ltd is based in Liaocheng, recognized as one of the major steel pipe production bases in China. The company focuses on the manufacture and supply of carbon steel pipes at competitive prices and with an emphasis on reliability and service.

Production capabilities include two complete lines: a cold-drawn line handling sizes from 1/4" to 5" OD, and a hot-rolled line covering 6" to 16" OD, with the capability to hot-expand to 20"–24". This breadth allows the company to offer pipes suitable for a range of applications and workflows.

The product portfolio encompasses carbon steel pipe products suitable for liquid services (ASTM A106 / A53 Gr. B) and pipe solutions for casing (P-110, K55, N80 and related designs). The company also supplies pipes for pipeline projects under API 5L specifications (GR. B, X42, X52, X60, X70), and steel pipes for construction requiring higher thicknesses (ST45, ST52). For mechanical uses, CK45-grade materials are featured. These offerings indicate the company’s capacity to support construction, pipeline infrastructure, and mechanical applications.

Shandong Zhongzheng emphasizes quality, competitive pricing, and service as core commitments to its customers. While the profile highlights a readiness to engage in long-term partnerships, there is no explicit information on certifications, export capabilities, or regional service networks in the available materials. The company presents itself as a supplier capable of meeting varied steel pipe specifications and sizes through its dual production lines, with a focus on delivering value to clients in the steel pipe sector.
