In order to raise the quality of the End Plates used for Concrete Pipe Pile, our corporation adopt the best and most reasonable way of technology in the steel plate production industry - Cold Bending Forming, it is a better way to ensure the quality of the products compare with either Hot Bending or Centrifugal Casting, because they both are based on the technology of raw material melting by their own factory, which way is hard to control the quality of the steel paltes, neither from chemical element nor mechanical property.Differently, our factory are using high-performance steel which are purchased from large-scale steel mills, we can trust their professional technology. So we can guarantee that all of the our produts can perfectly measure up with the National Standard Q235,and the International Standard JIS G3101 SS400 And because of the technical speciality of Cold Bending, low performance steel can not even pass through the production process; and the the Q235 standard material steel’s chemical elements will not be changed because of no heating process; so, we can also guarantee our produsts’ quality with all the process of pipe making and the hammering, and also the welding.   2.We have advanced machines for bending, welding, lathing, punching and milling production process. 3. We can produce all kinds of specfication within OD 250mm – 1200mm.
