Stainless Steel Channel is a long steel with groove cross-section. There are common Stainless Steel Channel and Light-weight Stainless Steel Channel. The indication of Type and Specification is Height (h)*Width (b)*Thickness (d). For example, 120*53*5 channel, means channel's Height is 120mm, Width is 53mm, Thickness is 5mm.
Usually, we use centimetre data of the Height to indicate channel's Type. The above channel is called 12# channel. If the Heights are the same, but there are several width and thickness, we usually add "a", "b", "c" to the Height to distinguish. The channel's specification range is from 5-40#.
It is mainly used for construction and steel frame structures, automobile manufacturing and other industrial structure use. It is mostly used with beam.
THE SURFACE OF STAINLESS STEEL :
| Finish | Characteristics | Applications |
| No.1 | Finished by hot-rolling, annealing and picking,characterized by white pickled surface. | Chemical industry equipment, industrial tanks. |
| No.2B | Finished by heat treatment, picking after cold rolling, followed by skin pass line to be more brighter and smooth surface. | General application,medical instruments, tableware. |
| BA | Bright teat-treatment after cold rolling. | Kitchen utensil, kitchen ware. |
| No.8 | A mirror-like reflective surface by polishing with finer abrasives over 800 mesh. | Reflector, mirror, interior-exterior decoration forbuding. |
| HL | Finished by cntinuous linear polishing. | Architectural purposes, escalators, kitchen ware vehicles. |
