Pre-galvanized trunking is stamped from steel sheets that have already been coated with zinc at the mill, resulting in a smooth finish ideal for indoor, climate-controlled environments. Hot-Dip Galvanized (HDG) trunking is submerged in a bath of molten zinc after the steel is cut and formed. This creates a much thicker, metallurgically bonded coating that covers all edges and welds, providing superior, heavy-duty rust protection essential for harsh outdoor, marine, or highly corrosive industrial settings.
Absolutely. While 50-1000mm covers the vast majority of standard infrastructure requirements, our advanced manufacturing equipment and dedicated engineering team allow us to produce highly specialized, non-standard dimensions.
