Bauhinia floor drain

Stainless steel floor drains are also subdivided into 201 and 304 materials.   Usually, the stainless steel floor drain of 304 material is more corrosion resistant than that of 201 material, and the service life is better, but at the same time, the price is higher than that of 201 material.
There are many kinds of surface treatment of stainless steel floor drains: electroplating, wire drawing, mirror, spray paint.
