Towers are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers. All finished surfaces shall be level and free of tears, burrs, clots and impurities.

Except otherwise specified elsewhere in the specification, the surface treatment and corrosion protection for all metal parts shall be in conformity with the latest revision of the standards listed below:

ASTM A 123 zinc (hot-dipped galvanized) coating on iron and steel products

DIN 55928 Protective painting of steel structure instructions

DIN 55945 Painting materials-Notions

DIN 18363 Paint work-Buildings

DIN 18364 Surface protection work for steel

DIN 53210 Determination of rust degree

DIN 55151 Determination of adhesion

ISO4628/3 Determination of rust penetration
