No.1

The surface finished by heat treatment and pickling or processes corresponding there to after hot rolling.

Chemical tank, pipe etc.

2D

When finishing acid cleaning by heat treatment or equivalent processing.Temper cold rolling is performed till proper gloss is acquired.

Areas without surface gloss requirement,such as construction, DDQ and general purpose.

2B

Those finished, after cold rolling, by heat treatment, pickling or other equivalent treatment and lastly by cold rolling to given appropriate luster.The surface brightness and flatness of No.2B is better than No.2D. No.2B could nearly satisfy comprehensive uses.

Medical equipment, Food industry, Construction material, Kitchen utensils etc.

No.3

Polished with abrasive belt of git#100 to #200, have better brightness with discontinuous coarse stria.

Kitchen utensils, Building construction etc.

No.4

Polished with abrasive belt of grit #150 to #180,have better brightness with discontinuous coarse stria,but thinner than No.3.

Kitchen utensils, Building construction, Medical equipment etc.

Hairline

Polished with abrasive belt of grit #150 to #320 on the NO.4 finish and has continuous polishing streaks.

Building Construction etc.

BA (No.6)

Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity.

Kitchen utensils, Electric equipment, Building construction etc.

Mirror (No.8)

The product have excellent brightness and prefer reflexivity can to be the mirror.

Building construction, decoration etc.

Processing

The whole process is done at high temperature and at the end is being cooled down

Cold rolled steel is heated and cooled at the room temperature and then rolled after again

Advantage

– Easier to make: heat it up, push through, cool down and that’s it!
– Cheaper than cold rolled
– Hot rolled steel is allowed to cool at room temperature and it’s free from internal stresses that can arise from quenching or
work-hardening processes
– Most popular shapes are hot-rolled (UC, UB, SHS, RHS, PFC, flats etc.)

– accurate shape (consistent and straight)
– a wider range of surface finishes
– a smooth and shinier surface
– bars are true and square and have well-defined edges and corners
– Tubes have better concentric uniformity and straightness.

Disadvantage

– dimensional imperfections caused by heating (expanding) and cooling down (shrink, warpage)
– rough texture on a surface, need to be removed and buffed before painting
– Slight distortions

– more expensive
– fewer shapes available cold-rolled (sheets, box section shapes: CHS, SHS, RHS)
– additional treatments can create internal stress within the material; this can cause unpredictable warping if the steel is not
stress relieved prior to cutting, grinding, or welding.
