Stainless steel trays are often used to hold surgical instruments during procedures. The fact that stainless steel (especially electropolished steel) is so easy to clean and can resist oxidation from exposure to blood and other bodily fluids makes it ideal for holding sterile tools.
 
Medical trays are made up of medical grade stainless steel, plastic, or other materials, and are used to store surgical instruments during operative procedures, autoclaving the instruments and sponges, and catheterisations, etc. These trays are low-maintenance, easy to clean and sterilise.
 
The Metal Tray acts like a skillet and also tends to cook much faster because of its ability to absorb more heat from the lamps. With the Metal Tray, you can get a sear on the bottom of proteins, proper toast on the bottom of vegetables and bread, etc.
