A custom metal vault is an outer burial container built from steel or reinforced alloy to protect a casket from soil pressure, moisture, and the weight of cemetery equipment over time. Unlike production-line units that come in fixed sizes and finishes, a custom vault is fabricated to the specific casket dimensions, steel gauge, and surface finish the buyer requires. CMV Fabrication manufactures custom metal vaults with air-seal construction and in-house powder coat finishing. Every vault is water-tested at the facility before it ships.
CMV Fabrication's metal vaults use air-seal construction, a design that traps an air pocket inside the dome to resist groundwater mechanically rather than relying on a chemical gasket alone. The vault shell is cut on CNC equipment and welded to continuous, porosity-free seams. Steel gauge and alloy are selected based on the burial site conditions, with heavier gauges available for high-load or high-moisture environments.
After welding, each vault receives a powder coat finish in CMV Fabrication's own coating facility. Powder coating cures at high temperature and bonds directly to the metal, producing a surface that resists chipping and corrosion over long burial timelines. Finish options include matte, gloss, metallic, and textured coatings, with custom color matching available. Personalized laser-cut graphics and emblems can also be incorporated into the vault exterior before the coating is applied.
CMV Fabrication works directly with funeral directors, cemetery operators, and families to specify and build custom metal vaults to order. The entire process is handled in-house, from steel cutting through welding, finishing, and water-seal testing. Funeral professionals who need recurring supply can establish standard configurations with CMV Fabrication for the casket sizes and site conditions they encounter most often. Individual buyers can contact CMV Fabrication to discuss specifications and receive a quote.
