Since 1986, Shijiazhuang Donghuan Malleable Iron Technology Co., Ltd. has been a trusted name in the pipe fittings industry. With over 30 years of manufacturing expertise, the company specializes in malleable iron fittings, ductile iron fittings, and gray iron fittings – core products widely used in construction, machinery, plumbing, and industrial applications.

We are excited to announce our participation in the 10th China Yiwu International Hardware & Electrical Appliances Expo, taking place from April 20 to 22 at the Yiwu International Expo Centre. You will find us at Booth C2C41, where we will showcase our extensive product range and manufacturing capabilities.

What We Bring to Yiwu Expo

Our main product portfolio includes:

Malleable iron pipe fittings

Tube clamps and double bolt clamps

Air hose couplings and conduit bodies

Camlock couplings

Carbon steel pipe nipples

Hydraulic fittings

Each product undergoes a rigorous production and inspection process: casting, annealing, shot blasting, galvanizing, threading, air pressure testing, thread inspection, and final packaging. This ensures reliable mechanical properties, excellent sealing, and easy assembly – qualities that our global customers have come to rely on.

Our Manufacturing Edge

We take pride in leading the industry with cleaner and more controlled production:

First in our factory to adopt electric stoves for casting and electric facilities for annealing and galvanizing.

Upgraded equipment for producing yellow shells – a pollution‑free process that allows precise control of material composition.

Advanced technology delivering excellent material finish, high interchangeability, and consistent quality.
