Galvanized  Buildings And  Architecture Thumb

Structural steel has been the material of choice in the building market for decades because of the numerous benefits it provides. While steel successfully and efficiently works when enclosed in the building envelope (framing), the portions of the steel exposed to the atmosphere need corrosion protection. Whether canopies, façade elements, handrail, architecturally exposed structural steel (AESS), or other exterior elements, hot-dip galvanizing is specified for optimum corrosion protection and enhanced aesthetic appeal.

The fact steel corrodes when exposed to the atmosphere should not be a deterrent to specifying the material; because, all construction materials (concrete, wood, etc.) do in fact deteriorate when exposed to the environment. However, steel is more upfront about its corrosion - the rust shows where weaknesses are forming, allowing maintenance crews to focus their attention for repairs. Other materials may hide the issues until the problem is magnified. The best way to conquer corrosion is to provide steel with a protective hot-dip galvanized coating, which has more than 150 years of proven, real world performance.
