HRPO steel is hot rolled steel processed with an acid solution – a technique called pickling – to remove contaminants and other unwanted elements such as stains and rust created by exposure to oxygen on the steel’s surface. Dipping the steel into tanks of hydrochloric acid causes a reaction that eliminates these contaminants, called scaling.
After the acid is rinsed off and the steel dried, a thin film of oil is applied to prevent rusting. Pickling and oiling makes the steel durable, malleable and cleaner to paint.
Applications of Hot Rolled Pickled and Oiled SteelFrom simple bends to complex draws or structural applications that require a specific strength level, hot rolled pickled and oiled steel is used for a wide range of applications that include but are not limited to:
Welding finishes
Reinforcements
Pipe
Tubing
Industrial storage racks
Automotive and other stampings
Air compressor housings
Filters
Agricultural equipment
Package strapping
Tanks
Light poles
