China OEM Metal Safety Grating - 1 hot rolled pickled&oiled steel coils – Lishengda

Product Presentation

Hot rolled steel is generally used in parts where rust proofing is not critical. There are processes that allow hot rolled sheets to prevent rust as well. This process is called HRP&O – Hot rolled pickled and oiled. During the pickling process an acidic solution is used to remove contaminants and other unwanted elements such as stains and rust. Once this pickling process is complete the acid is rinsed off and dried. Once finished drying we then apply a thin film of oil to the steel to prevent it from rusting.

The steel sheet pile production

Pickling and oiling improves hot-rolled durability and workablility at a low cost. It provides a cleaner surface hot rolled product suitable for painting with a limited barrier to rust formation. It is an all purpose steel product used for roll-formed shapes, pipe, tubing, industrial storage racks, automotive and other stampings, air compressor housings, filter housings, agricultural equipment, package strapping, and much more.

What is Hot Rolled Pickled & Oiled Steel?

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 HRPO Steel

From 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
● Gas cylinders
● Guardrails
