Use at temperatures above this level can result in the peeling of the zinc at the intermetallic layer. Galvanized steel is suitable for high-temperature applications typically up to 392☏ (200☌). The resulting coated steel can be used in much the same way as uncoated. Find wiring and a large variety of other harnesses, harness connectors, electrical socket assemblies lamp assemblies, fuses (5, 7.5, 10, 15, 20, 25 and 30 amp), drain plugs, door hinge pins, 10 and 12 gauge wire and so much more.

The types of fittings to be used based on the designer's calculations of fitting losses (i.e., square versus 45 entry taps, conical versus straight taps, etc.). Select from dozens of different connectors, plus nuts, washers and clips. The process of hot-dip galvanizing results in a metallurgical bond between zinc and steel with a series of distinct iron-zinc alloys, creating a versatile and affordable material for manufacturing ductwork and duct components. A comprehensive duct layout indicating sizes, design airflows, pressure class, and routing of the duct system. Galvanized steel is widely used in ductwork applications where rust resistance is needed and can be identified by the crystallization patterning on the surface (often called a “spangle”).
When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbon dioxide to form zinc carbonate, a dull grey, relatively durable material that stops further corrosion in many circumstances, protecting the steel below from the elements.
The steel passes through a molten bath of zinc at a temperature of around 860☏ (460☌). Most ductwork manufactured with galvanized metal is hot-dip galvanized, a process of coating steel with a thin zinc layer.
