These tests indicate that bare galvanizing is not the most adequate coating for a high-chloride-content environment and high RH, especially with high wind speeds that slowly erode the galvanized steel.
From cooling tower chassis and components, vehicles, landscape equipment, air conditioning systems, metal structures, shipping containers, wrought iron fences, garage door mechanisms, weapons, duct works, steel doors and frames, process plant equipment, external radiators, battery boxes, chassis, interior door, fold, weld seam areas and to locks CarWell is the right choice for the job of fighting corrosion.
Proper applications of coatings will result in longer performance and better surface protection where coatings have been used. Use of a wet film thickness gauge or comb makes translation of what has been applied easy to understand and you can then calculate what happens to dry film thickness by review of product technical sheet.
Reinforcement in new concrete is generally protected from corrosion due to the high alkaline nature of the concrete itself. The high pH of the concrete (usually greater than 12.5) causes a passive oxide film to form on the steel. Environmental factors can affect this protective oxide film and induce the formation of corrosion cells. Once corrosion starts, some parts of the reinforcement become anodic, discharging iron ions (current) into the electric cell.
