Steel Doors and Windows for Coastal California — Hot-Dip Galvanized Protection
California coastal properties present one of the most demanding environments for architectural steel. Salt air, high humidity, and UV exposure combine to accelerate corrosion in unprotected steel fenestration. Herrero offers hot-dip galvanizing on all products to address this challenge, delivering steel doors and windows that perform and look exceptional on the California coast for decades.
Why Coastal California Requires Hot-Dip Galvanizing
Standard powder coat alone is not sufficient corrosion protection for properties close to the ocean. Salt particles carried on coastal air can penetrate powder coat finishes over time, initiating rust beneath the surface. Hot-dip galvanizing creates a metallurgical bond between zinc and steel — not a coating on top of the steel, but an integral zinc-iron alloy layer that provides sacrificial protection. Combined with powder coat topcoat, hot-dip galvanized steel provides dual-system protection designed for the most demanding coastal environments.
