Corrosion resistance steel water channel Construction steps:
  • The corten steel do Shot blasting treatment by shot blasting machine.
  • The corten steel should be cutted and bentted by CNC machine according to the design drawing.
  • Welding the corten steel materials as the drawing.
  • Cleaning the surface again. Then do rusting treatment.
  • When the weathing steel surface color becomes which u want, then do rust curing treatment. 
  • Installing the corten steel at the park by the way of welding and Lay the keel behind the back.
