The majority of metal caskets available on the market today are known as "protective" caskets. This terminology reflects that they are manufactured with a one-piece rubber gasket that runs around the inner lid of the casket.
Once closed, a locking mechanism draws the lids onto the base and the gasket forms a seal. This protective seal protects the deceased from the entrance of air and other gravesite elements.
Many higher quality metal caskets utilize a sophisticated magnesium rust inhibitor process. Metal caskets are commonly manufactured in 20, 18 and 16 gauge metals. Interiors are tastefully coordinated in a variety of materials form crepe to velvet allowing for a range of pricing to meet a wide variety of budget concerns.
