Outdoor galvanized IP68 electrical enclosures require both high ingress protection and outdoor durability. Galvanizing methods, zinc coating condition, base steel, bending, welding, cutting, and drilling all affect final protection and performance.
Cut edges, weld zones, and field-drilled holes may lack original galvanizing, requiring touch-ups or secondary protective treatments per project specs. Fasteners, hinges, locks, and gaskets must also match galvanized steel and outdoor environments to prevent galvanic corrosion and premature seal aging.
Additionally, outdoor cabinets must account for top water pooling, bottom drainage, plinth connections, UV exposure, temperature shifts, and condensation. IP68 indicates water ingress protection only under specific test conditions and does not replace durability evaluations for coatings and outdoor environments.
