Solid brass (C260 cartridge brass, 70% copper, 30% zinc) is the reference material for commercial sensor faucets. It combines high mechanical strength (70–80 ksi yield), excellent corrosion resistance to aggressive cleaning chemicals, and work hardening under stress — properties essential for infrastructure environments.
Unlike zinc alloys or thin stamped brass, BathSelect commercial faucets are machined from solid brass bar stock with minimum 2.5 mm wall thickness, ensuring structural integrity under load, impact, and torque.
C260 brass work‑hardens under stress: when impacted or overloaded, the material becomes locally stronger, resisting crack propagation. This is critical in abuse‑resistant designs. Zinc alloys lack this behaviour and tend to fracture abruptly.

All BathSelect commercial solid brass sensor faucets are third‑party tested to meet or exceed these standards. Full compliance documentation available for submittals.
Commercial solid brass sensor faucets installed in airport terminals, hospitals, transportation hubs, and institutional infrastructure environments operate under extreme duty cycles exceeding 500,000 activations annually. Infrastructure-grade maintenance ecosystem engineering enables modular serviceability, rapid component replacement, and continuous operational reliability without requiring full fixture replacement.
Modular Serviceability Architecture
Solenoid valves, infrared sensors, control electronics, and aerator assemblies are independently replaceable without removing the faucet body, enabling rapid maintenance procedures and minimizing infrastructure downtime.
Rapid Maintenance Performance
Infrastructure maintenance engineering enables component replacement in less than 10 minutes. Below-deck access architecture supports efficient servicing in high-traffic environments including airport terminals and healthcare facilities.
Long-Term Spare Parts Availability
Regional spare parts infrastructure ensures component availability for 10+ years, supporting lifecycle service continuity and reducing total infrastructure lifecycle cost.
