Galvanized steel raised bed kits
Galvanized steel beds have become extremely popular due to their 20+ year lifespan, modern appearance, and near-zero maintenance. The zinc coating (or Aluzinc Al-Zn-Mg coating on premium models) prevents rust and corrosion. Brands like Birdies, Vego Garden, and Vegega offer modular kits in various sizes from $80-400. Steel is completely food-safe for growing edibles. Key advantages: immune to rot, decay, and termites; thin walls maximize interior growing space; soil warms faster in spring for earlier planting. Key caveats: soil near metal edges runs 8-10 degrees F warmer than center soil, which can stress shallow roots in hot climates. Mitigate by planting heat-tolerant herbs and flowers along edges, or add interior insulation board. Steel beds are heavy when assembled but most kits use bolt-together panels that one person can install. Avoid very cheap thin-gauge steel that dents easily.
