This heavy-duty spiked garden landscape edging is constructed from solid 1.5mm thick galvanized steel covered with uniform matte black powder coating, delivering superior rust-proof, UV-resistant and all-weather durability for long-term outdoor use. Each edging strip measures 1060mm in length, featuring a 16cm decorative section exposed above soil and 8cm integrated sharp spikes for underground anchoring, forming a full total height of 24cm. The package includes 4 interlockable panels that can be freely spliced to create straight or curved boundaries for lawns, gravel areas, flower beds and walkways. Built-in ground spikes eliminate extra installation hardware; simply press strips into soil to build a tight partition that blocks grass root spread, contains mulch and gravel, and prevents material cross-contamination between landscaping zones. The minimalist matte black finish matches modern, minimalist and industrial courtyard landscape styles perfectly.
