一、The stainless steel of Deli shower room is all 304 stainless steel. The main characteristics of this material are good hardness, high bearing capacity, non-oxidation, good corrosion resistance, beautiful and high-grade, easy to maintain, and long service life.（After 48 hours of copper accelerated acetic acid salt spray test (PH value is between 3.2-3.5), it is equivalent to 20 years of bathroom environment.）
二、Many shower room manufacturers choose 2 series stainless steel in pursuit of maximum profit and affordable price. It has poor corrosion resistance and is easy to oxidize. The metal surface is constantly rusted and its service life is greatly reduced.
三、There are also many manufacturers on the market that use copper alloys. This material is mainly used for shower hinges, wall clips, and poles with good electrical conductivity, thermal conductivity, plasticity and corrosion resistance.However, due to the material characteristics, the hardness is low, and it is easy to rust when exposed to the air for a long time.
