A steel cabinet is a durable, multipurpose storage unit made from metal, often cold-rolled steel, designed for strength and longevity. Key features include a powder-coated finish for protection, heavy load capacity, locking mechanisms for security, and adjustable shelves for customizable storage. These cabinets are resistant to water, humidity, and wear, making them suitable for environments like offices, workshops, garages, and homes, and they often come as "knock-down" units for easier assembly and transport.
