- Material and finish: Choose between powder-coated steel, carbon steel with anti-rust coating, or stainless steel for outdoor longevity. Consider rust resistance, weather exposure, and soil contact.
- Load-bearing capacity: Look for brackets that specify thick gauge steel and reinforced corners to support soil weight and plants, especially in taller beds.
- Design and aesthetics: Decorative brackets can enhance visual appeal, but ensure they don’t compromise strength or edge safety.
- Installation and hardware: Check included screws and compatibility with your wood type (e.g., hardwood vs softwood). Some sets provide all hardware; others may require additional fasteners.
- Stackability and height: If building taller beds, prefer stackable or taller brackets to reduce weed infiltration and improve accessibility.
- Edge protection: Rounded or smooth edges help prevent injuries to people and pets and protect mower lines from bed edges.
