04 / Why Shengzhun

From coil to coated pipe, in one yard

A distributor needs one thing from a supplier: the pipe that arrives should match the sheet that was quoted.

See the production line

Own production line

Pipe is formed, welded and tested in one yard, so production status can be confirmed at the mill rather than through a trading layer.

Specifications checked before quoting

Diameter, wall thickness, grade, standard and coating are confirmed line by line before a price is issued.

Coating and fabrication in the same flow

Coating, cut-to-length and beveling are completed before dispatch, which keeps site work to jointing and testing.

Export packing and documents

Packing, loading and document preparation are planned around the destination and the terms of the order.
