Exceptional Corrosion Protection
Thermal Diffusion Galvanizing (TDG) is a method of applying a uniform, protective, zinc iron alloy coating to steel parts using a metallurgical vapor diffusion process. TDG gives cutouts and pole line hardware manufactured by Hubbell a longer life in corrosive environments than hot-dipped galvanizing (HDG). The longer life offered by these products means utilities spend less time and money replacing corroded parts, especially in coastal or industrial regions.

Performance Without the Price
TDG offers corrosion protection approaching the performance of stainless steel, but at a fraction of the cost, making TDG the economical choice. Unlike HDG, the internal threads of TDG coated bolts are coated to provide total corrosion protection. This ensures issue-free nut removal. In the salt fog test above, over a period of 3,000 hours, TDG clearly outperformed HDG.
