It is the most standard pitch in Japan as prescribed by ISO (International Organization for Standardization) standard. The most frequent distribution in Japan.

■Material: Stainless steel
Most representative stainless steel (equivalent to SUS304)
The strength is almost equal to "iron".
Excellent corrosion resistance and good mechanical properties.
Although it is normally not magnetic, it can harden due to cold processing, and it may cause magnetism.

■Surface treatment: fabric
Surface treatment/plating is untreated.
Therefore, corrosion resistance and appearance are the characteristics and color of the material itself.
