We can produce Heavy wall
pipe (Thick wall steel pipe)
with OD: 38--5000mm,
Wall thickness: 3.5--120mm.
With advanced coating line and morden port beside the workshop,
we can provide FBE, 3PE coating for the pipe(up to OD3000mm).
And we had produced this kind of piling pipe with big length and weight.
