At 15cm tall this black border sits barely above the mulch, which is exactly what a gravel path or a vegetable plot needs when the aim is separation rather than screening. Five metal panels each measure 102cm wide and bend by hand, so a bed with rounded corners is no harder to edge than a straight one. The connectable system lets panel meet panel until the run matches the bed. A sleek black powder coated skin over robust metal holds off rust season after season. Fitting means pressing each length into moist ground or a shallow slit trench, with no heavy digging and no specialist kit.
