SS304 stainless steel floor drains combine military-grade corrosion resistance (withstands acids, alkalis, and saltwater), hygienic design (smooth surface prevents bacterial buildup and secondary water pollution), and lifespan exceeding 100 years even under high-velocity water flow (60m/s+). Ideal for homes, hotels, and industrial sites, they outperform plastic alternatives with zero lead contamination and extreme temperature resilience (-270°C to 400°C).
