Shijiazhuang Teneng Electrical & Mechanical Equipment Co., Ltd

Shijiazhuang Teneng Electrical & Mechanical Equipment Co., Ltd was founded in 2009 and focuses on steel pipe production equipment, cold roll forming mills, and slitting and cut-to-length lines. The company integrates R&D, production, sales, and after-sales service, and has around 200 employees. Its R&D team has 39 professional staff, including 8 senior engineers, and its core members have more than 20 years of experience in welded pipe equipment.

Teneng holds ISO 9001 and CE certifications and reports 40 patents. Its patented technologies include a quick-change roller stand, which lets a mill switch between square tube sizes with less downtime, and a horizontal forming roll stand that improves square tube forming accuracy. It has also developed a flexible cold-bending forming technology. In early 2026 the company announced that a new factory had been commissioned, and it exhibited at Tube & Wire in Düsseldorf.

Teneng says its projects span more than 20 provinces in China and over 40 countries, including the United States, Italy, Ukraine, India, Mexico, Kazakhstan, Saudi Arabia, and Vietnam. Recent shipments it highlights include an ERW127 tube mill to Italy and an ERW127 mill with a slitting line to South America.
