Aluminum is the material of choice for outdoor columbarium structures because it does not rust. Steel corrodes when exposed to moisture over time, and stone can crack under repeated freeze-thaw cycles. Aluminum resists both. A powder-coated aluminum columbarium maintains its structural integrity and visual appearance across decades of weather exposure without requiring the periodic sealing or resurfacing that stone and concrete demand.
CMV Fabrication selects aluminum alloys for columbarium construction based on the structural load the unit needs to carry and the environmental conditions at the installation site. Coastal locations, high-humidity regions, and sites with heavy seasonal temperature swings each present different corrosion profiles. The alloy grade and coating specification are matched to those conditions during the design phase so the finished structure is engineered for where it will actually stand.
