Abstract
A tube product and improvement in the production of coating tubing includes hot dip galvanize zinc coating of tubing, and before solidification of the zinc coating, clear coating of the tubing with organic polymer coating. The heat of the hot dip cures the clear coating, and the clear coating preserves a consistency and reflectivity of the zinc previously unseen in finished products. In additional preferred embodiments, organic polymer coatings are applied to zinc coated and uncoated tubing, and the organic polymer coatings are applied by electrostatic powder coating.
