2D

No.2D

This finish is not reflective and is made through cold rolling, heat treatment and pickling. Its typical uses include petrochemical plants, auto parts, construction materials and pipes.
2B

No.2B

This finish is made by applying a light cold rolling pass to No.2D. It is more reflective and less rough and provides better mechanical properties than No.2D. It is commonly used for almost all applications.
8K

8K

Grinding and polishing the surface of stainless steel is a highly refined polishing process that makes the stainless steel surface smooth and highly reflective, giving it a mirror-like effect. It is commonly used in construction, automobile and other fields.
BA

BA

This finish is made through cold rolling, bright annealing, heat treatment and then a light cold rolling pass. It is widely used for applications where a highly reflective surface is desired, including home appliances, small mirrors, kitchen appliances and architectural materials.
NO.1

No.1

This finish is created through hot rolling, heat treatment and pickling. It is ideal for materials to be cold-rolled, industrial tanks and chemical facilities.
NO.4

No.4

This finish is made through polishing with 150-180 grit abrasives. High grit numbers create finer polishing lines and more reflective finishes than No.3. This finish is widely used for bathtubs, architectural materials and food processing.
HL

HL

Featuring a series of patterns, this finish is made through polishing with moderate grit abrasives. Its common uses include sashes, doors or other panels of buildings.
EMBOSSED

EMBOSSED

The coating is embossed with a special mold or roller to form a raised pattern or texture, giving it a three-dimensional and visual effect. It is often used in architectural decoration and other fields.
