Barnes Pipe stocks most material bare.  To reduce the likelihood of rust developing, we can prime paint your order in our standard grey primer, or an alternate red primer.  We also offer Hot Dip Galvanizing! Hot dip galvanizing not only creates a more durable coating, but since the pipe is completely submerged it gets to all areas of the pipe that would otherwise be inaccessible by brushing or spraying on primer.  This complete coat of galvanizing provides an unbroken protective barrier against the elements thus making your steel pipe last longer.
