Stainless steel strips is the cold rolled stainless steel under 5.00 mm in thickness and under 610mm in width.
The various types of finish procurable on cold-rolled stainless strips are No.1 Finish, No.2 Finish, BA Finish, TR Finish, and Polished Finish.
The types of edges available on stainless strips are No.1 edge, No.3 edge, and No.5 edge. These strips are inventoried in 200 series, 300 series, 400 series.
Our best-selling product includes 201 stainless steel strips, 202 stainless steel strips, 301 stainless steel strips, 304 and 304L stainless steel strips, 316 and 316L stainless steel strips, 409, 410, and 430 stainless steel strips.
The thickness of them ranges from 0.02mm to 6.0mm. The minimum tolerance in thickness is only 0.005mm. For metal, we are serious.

Finish for Stainless Slit Coil
No.1 Finish: Cold-rolled to specified thickness, annealed, and descaled.
No.2 Finish: Same as No.1 Finish, followed by a final light cold-roll pass, generally on highly polished rolls.
Bright Annealed Finish: A bright cold-rolled finish retained by final annealing in a controlled atmosphere furnace.
TR Finish: Cold-worked to obtain specified properties.
Polished Finish: It is also available in polished finishes such as No.3 and No.4.
Note:
No.1— Appearance of this finish varies from dull gray matte finish to a fairly reflective surface, depending largely upon composition. This finish is used for severely drawn or formed parts, as well as for applications where the brighter No.2 Finish is not required, such as parts for heat resistance.
No.2— This finish has a smoother and more reflective surface, the appearance of which varies with composition. This is a general purpose finish, widely used for household and automotive trim, tableware, utensils, trays, etc.
No.3— A linearly textured finish that may be produced by either mechanical polishing or rolling. Average surface roughness may generally be up to 40 micro-inches. A skilled operator can generally blend this finish. Surface roughness measurements differ with different instruments, laboratories, and operators. There may be overlap in measurements of surface roughness for both No.3 and No.4 finish.
No.4—linearly textured finish that may be produced by either mechanical polishing or rolling. Average surface roughness may generally be up to 25 micro-inches. A skilled operator can generally blend this finish. Surface roughness measurements differ with different instruments, laboratories, and operators. There may be overlap in measurements of surface roughness for both No.3 and No.4 finish.
Bright Annealed Finish— A smooth, bright, reflective finish typically produced by cold rolling followed by annealing in a protective atmosphere so as to prevent oxidation and scaling during annealing.
TR Finish— The finish resulting from the cold-rolling of an annealed and descaled or bright annealed product to obtain mechanical properties higher than that of the annealed condition. Appearance will vary depending upon the starting finish, amount of cold work, and the alloy.
Edges for Stainless Slit Coil
No.1 Edge: A rolled edge, either round or square as specified.
No.3 Edge: An edge produced by slitting.
No.5 Edge: An approximately square edge produced by rolling or filing after slitting.
