Hot Dipped Galvanized Steel
Hot dipped galvanizing is a process of coating steel with a thin layer of zinc, which serves as a barrier between the steel and the elements. The steel is dipped into a molten bath of zinc, which creates a metallurgical reaction that forms an alloy coating. This coating, or barrier, provides superior corrosion protection from harsh environmental conditions.
Hot Dipped Galvanized Steel Applications
The hot dip galvanizing process provides corrosion control that is extremely desirable in a myriad of applications and industries, including energy, utilities, automotive, agriculture, construction, HVAC, transportation, chemical processing, telecommunication, outdoor recreation, and more. With a low initial cost, low maintenance, and increased longevity, galvanizing is a versatile and economical way of protecting the steel substrate. Also, the zinc coating provides excellent corrosion and rust resistance, ultraviolet light protection, and superior non-flaking properties
