High production efficiency, line speed can be up to 110m/min.

√ High yielding, the machine works stably at a high speed.

√ Low wastage, low unit wastage and low production cost.

High accuracy, diameter error is only 0.5/100 of the pipe OD.




GI, carbon steel and stainless steel tubes for metallurgy, construction, transportation, machinery and vehicle industries.

Forming process

Round pipe Cold roll forming process Good roller design
ZTF forming technology Reduce 60% roller cost, save roller changing time, increased production efficiency
Square & rectangular pipe General round-to-square process Stable forming process
Round to square with turkshead Good pipe quality, reach same wall thickness with round pipe
Directly squared forming technology

1) Compare with round into square&rectangle forming way,this way is better for the shape at the edge of cross section,comparatively, semi-diameter of inner arc is Small,and the brim is flat,outlook is regular.

2) the whole line load is low ,especially the sizing parts.

3) The width of steel strip is small about 2.4-3% than round into square & rectangle,it can save the consume of raw material.

4) It adapt the multi-point bending way, avoid the axial force and side abrasion, reduce the forming step while ensure the quality,meanwhile it reduce the power wastage and roller abrasion.

5) It adapt the combined type roller on the most of the stands,it realize that one set of roller can produce dozens of square&rectangle pipe with different specification,it decrease the store of roller,low the cost about 80% on roller, Fast the bankroll turnover, short the time one new product design.
