The Seamless Steel Tubes are produced by Cold Drawn or Cold Rolled,
for small diameters below 88.9mm, the bigger diameter are produced

These steel tubes will be used for mechanical engineerings, could
be also used as mother tube for further cold drawn production to
achieve better tolerance and surface smoothness as precision steel
tubes.
