ChesterBlohm says: These days’ Metal caskets are in huge demand among the families who have lost their loved ones. These caskets are essentially tamper proof caskets where they are manufactured with one piece rubber gasket that runs through the inner lead of the casket. These Metal caskets in USA are known as “protective caskets”. They are very long lasting and made of different metals like magnesium that comes in 20, 18 and 16 gauge. Just to remember smaller the gauge thicker the metal. They make the inside of the coffin extremely beautiful that will only offer peace to the loved one.
