Uniformly galvanized steel components are the product of design and fabrication working with the galvanizing process. Adopting the prescribed design practices will deliver the optimal quality of galvanizing coating, reduce galvanizing cost and ensure the safety of our galvanizing personnel.
Large components may be processed with double-end or double-depth dipping. The item is lowered into the bath, dipping half the length or depth. When this is zinc coated, it’s raised from the bath and turned to dip the remaining section. This may cause a visible “join line”, refer Double Dipping Chart.
Large scale structures produced in modular components for construction onsite can simplify handling and transport. Modular design techniques may also produce cost benefits in manufacturing and assembly. However, when cutting or welding after galvanizing follow the Thermal Cutting instruction to ensure the corrosion protection for these areas is equivalent to that provide by HDG.
