The steel gauge and alloy composition of a metal burial vault determine how much load the enclosure can handle before the walls begin to deflect, and how resistant the metal is to corrosion from soil chemistry and groundwater contact over time. Standard carbon steel in heavier gauges provides strong load-bearing performance at a practical cost and is the most widely used material for burial vaults where structural capacity is the primary concern. Stainless steel and reinforced alloy configurations offer greater corrosion resistance for burial sites in coastal regions, flood-prone lowlands, high water table zones, or areas with acidic soil conditions.
CMV Fabrication works with buyers to match the material specification to the conditions the vault will actually face. A burial site with dense clay soil and heavy seasonal moisture requires a different gauge and alloy recommendation than a well-drained site with sandy or loamy ground. Bringing site information into the conversation early allows CMV Fabrication to recommend the right combination of strength and corrosion resistance before fabrication begins, so the vault that arrives at the cemetery is built for what is actually in the ground.
