VEVOR Metal Raised Garden Bed, 12 x 4 x 1 ft Outdoor Galvalume Planter Garden Box, Open Bottom Design, Large Planter Raised Bed for Growing Vegetables, Flowers, and Succulents, Galvanized Color

The green color finish is an exterior powder coating applied over the galvanized/galvalume steel panels, rather than a pigment embedded within the metal itself. While the underlying galvanized steel panels are highly durable and weather-resistant, direct impact from a high-RPM string trimmer/weedwacker line will chip, scratch, or scour the outer powder-coated layer If this answer doesn't resolve the current issue, please reach out to us again for assistance.
