Enhanced Safety & Reliability
Increased Operational Performance
Environmental Protection
Durable Thermal diffusion galvanizing products
TDG is the economical choice for utilities in coastal and industrial regions looking to improve the resilience of their pole line hardware. Unlike HDG, the internal threads of TDG coated bolts are coated to provide total corrosion protection and ensure nut-free removal.
Improved Corrosion Defense
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 a longer life in corrosive environments compared to hot-dipped galvanizing (HDG).
Performance Without the Price
Enjoy the exceptional performance and durability of stainless steel without breaking the budget. The internal threads of TDG bolts are coated to provide total corrosion protection, ensuring seamless nut removal.
Diverse Product Selection
We offer utilities access to a wide array of corrosion-resistant Pole Line Hardware and Cutouts, including top quality TDG products manufactured under ISO 9001 process control and tested in our own facilities.
