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.
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.
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.
