A working forge, not a trading desk
Forging, machining, heat treatment and inspection are done in our own shops in Dingxiang, Shanxi - which is why drawings, material substitutions and inspection scope can be answered by the people who do the forging.

D51 ring rolling mill, rings up to 240 mm thick; 8 t, 3 t and 2 t hammers; cylindrical forgings up to 8 m long and 800 mm in diameter.
