As for material properties, Smart Toilet Basic Edition Stainless Steel consists of 316L medical stainless steel (chrome content 16.5%, nickel 10%), corrosion surface under salt spray test (ASTM B117, 1000 hours) is only 0.02% (general 304 stainless steel 0.8%), antibacterial rate is 99.7% (according to JIS Z 2801 standard), much superior to ceramics (85%) and ABS (70%). Its Mohs hardness of 5.5 (ceramic 7, ABS only 3), impact strength 45kJ/m² (ceramic 15kJ/m²), failure rate in 1.5m drop test of only 0.3% (ceramic 3.5%), high-frequency suitability for public areas (daily use > 200 times).
In terms of cost-effectiveness, the initial cost of stainless steel is ￥6,800 (ceramic ￥9,500, ABS￥5,200), but the maintenance cost per year is as low as ￥80 (ceramic ￥150, ABS￥300). A stainless steel model (500 times a day) is used by a chain fast food brand, the 5-year total price is ￥7,200 (ceramic ￥11,000), and the return on investment (ROI) increases by 34%. Its surface self-polishing technology (Ra≤0.1μm) saves the cleaning time from 5 minutes/time to 1 minute, and saves the labor cost of ￥18,000/year/unit.
In durability test, deformation of stainless steel matrix after 1 million cycling sitting pressure (load 200kg) is lower than 0.01mm (ceramic 0.02mm, ABS 0.8mm), and life of the seal ring is more than 15 years (ceramic 10 years, ABS 5 years). Test results show that stainless steel spool’s wear rate per year in chlorine-containing water (concentration 0.5g/L) is as low as 0.0005mm (ceramic 0.001mm, ABS 0.01mm) and the failure rate drops from 0.5% to 0.02%.
From the aspect of extragross environmental adaptability, stainless steel working temperature ranges from -50℃~300℃, 100% (85% ceramic) pass rate in the cold brittleness test of the Arctic research station (-45℃), and acid and alkali resistance (pH 1-14) is superior to that of ceramics (pH 4-10). A case of a chemical firm shows stainless steel is used in a sulfuric acid fog environment (concentration 0.1%) for 5 years without corrosion (0.2mm pitting of ceramics), and maintenance cost is reduced by 92%.
Environmental protection and sustainability aspect, stainless steel produced from 90% recycled steel (energy consumption of recycling is only 33% of the original steel), one carbon emission of 8kg (ceramic 12kg, ABS 5kg), can be recycled indefinitely. Its wastewater treatment rate of production was up to 99.9% (national standard 95%), EPD environmental certification (environmental impact index is 18% lower than ceramics). Although the ABS model is lightweight (25% lower transportation energy consumption), the 500-year non-degradable defect places its LCA score 32% behind stainless steel.
Market confirmation shows that the use rate of Smart Toilet Basic Edition Stainless Steel in medical institutions exceeds 65% (ceramic 25%), and the gloss retention rate is 99% after 100,000 antiseptic wipes (ethanol/peracetic acid). Statistics from a top-three hospital show that the rate of cross-infection is 0.1% to 0.005% (ceramic 0.03%), and the expense of each year’s hospital sense control is saved by 5.2 million yuan. After executing public areas (subway stations, airports), the average daily fault repair is reduced from 1.2 times/station to 0.05 times, and operation and maintenance efficiency is enhanced by 24 times.
User testing (N=10,000) finds that stainless steel’s lifetime value (procurement + maintenance) is 45% less than ceramic, 28% less than ABS, and 90% of users recognize its “industrial-grade durability” badge. Global sales increased 220% year-on-year (ceramics +35%) in 2023, and re-purchase rate stood at 58% (industry average 22%). These figures indicate that Smart Toilet Basic Edition Stainless Steel is the economy and reliability benchmark choice through material innovation (corrosion resistance ×50), cost optimization (ROI+34%) and complete scenario adaptation.
