Note on selecting the stainless steel type?

The stainless steel is not completely rustproof. It is only rustproof in the correct condition.

* For interior decoration or furniture, stainless steel 201 or 304 (SUS201, SUS 304) can be used. However, the type 201 should only be stored in a dry condition.

* For outdoor use with polluted air, in extremely humid environment or in a place with salty steam, e.g. at sea or in the swimming pool, the type 316 or 316L should be used.

* To bear the large load, the carbon steel is a good choice. The surface can be galvanised or painted depending on the environmental conditions.
