1. Ground Preparation Before Installation

Regardless of whether the bent metal garden borders are straight or curved, ground preparation must be completed before installation:

First, excavate a trench along the designed trajectory, 10–15cm deep and slightly wider than the border thickness (if the soil is hard, moisten it with a watering can first to facilitate digging); Then clear stones and weed roots from the trench to prevent uneven installation. Finally, lay a 2cm layer of fine sand at the bottom. Compacting this ensures the edging sits flush with the ground, minimising settlement risks.

2. Key Points for Installing Curved Edging

When installing pre-bent corten garden edging, follow the curve's natural flow: after placing the edging in the trench, press down firmly along its top edge to ensure it conforms to the ground's curvature. Then secure it using 20cm galvanised steel nails driven in at 50cm intervals along both sides (at a 45-degree angle for enhanced hold). For sharper curves, reduce spacing to 30cm to prevent the edging from springing back.

3. Alignment Techniques for Straight Edging

Where straight boundaries are required, drive wooden stakes at both ends of the trench. Stretch a cotton cord as a reference line and position the steel garden edging along this line, ensuring a uniform height (recommended 5-8cm above ground level to prevent grass encroachment during mowing). Secure with steel nails, then recheck alignment against the string. Gently tap the edging to adjust for any misalignment.
