(6)preliminary drawings for these cylinders

hydraulic cylinder with material of rod is S50C-H (JIS) and the cylinder tube is STKM 13K (JIS-Japanese standard)

1/ piston rod must be made of stainless steel plated hard chrommium   or
2/ Piston rod must be made of high quality carbon steel coated ceramic

buyer are not professional for manufacturing of cylinder, so they request manufacturer must be supplied for these dimensions for them

if supplier can not match all requirement,it is not strange ,buyer from vietname and import from Korea before.so please mention your description in details,like material of piston rod is not stainless steel ,but others,......
