The Supreme Metal is a commercial underbar sink with multiple compartments ("wells") and faucets designed for use in restaurants or bars. Commercial Grade: These units are constructed from durable stainless steel (typically 20 gauge, 300 series) suitable for high-volume commercial use. Configuration: The description suggests a large unit, likely with five sink wells (compartments) and three faucets, which typically would be splash-mount (mounted on the backsplash) or deck-mount (mounted on the rear deck of the sink). Purpose: They are used in commercial settings for washing, rinsing, and sanitizing glassware and utensils, often integrated into a bar setup with drainboards.
