Stainless steel upper cabinets come in numerous designs. Essentially they are wall mounted cabinets that have doors and adjustable shelving inside. Upper cabinets are fabricated and installed in sections. Each section of upper cabinet typically does not exceed 48″ in length. During installation the cabinets are securely mounted to the wall using heavy duty brackets. The doors are fabricated with a double wall which makes them extra strong and rigid. They are then attached to the cabinet body with your choice of several hinges. Most often commercial use cabinets will use a piano hinge which is welded directly to the cabinet body. Cabinets doors are also available in locking and non-locking configurations with your choice of pull handle.
