Pro-grade rigid 14-gauge steel edging that makes the crispest, longest-lasting mow strip or border. The 4-inch profile blocks grass runners and stays put once staked. But the rigid 8-foot sticks are awkward to transport and can't do tight curves, the cut ends are sharp around bare feet, and it costs more per foot than plastic.
Pros
- Heavy 14-gauge steel holds a crisp, professional-grade edge for years
- Taller 4 in profile blocks grass runners and contains mulch or gravel
- Bends to gentle curves yet stays put once staked, unlike plastic coil
Cons
- Rigid 8 ft sticks are awkward to transport and can't do tight curves
- Cut steel ends are sharp and need care around kids and bare feet
- Costs noticeably more per foot than recycled-plastic coil edging

Frequently Asked Questions
- Does steel edging stop grass from creeping into beds?
- Largely, yes — a 4 in tall profile blocks grass runners and also contains mulch or gravel, which shorter edging does not. That height is the main reason to choose steel over coil.
- Can steel edging follow curves?
- Gentle ones. Rigid 8 ft sticks bend to soft curves and then stay put once staked, but they cannot do tight radii — that is where flexible coil edging wins.
- What should you watch out for during install?
- Cut ends. Trimmed steel is sharp and needs care around kids and bare feet, and the 8 ft sticks are awkward to transport home. It also costs noticeably more per foot than recycled-plastic coil.
