GRS wire nails NOT galvanized are specially designed for fixing artificial grass. The wire nails are easy to hammer into the artificial grass . The non-galvanized wire nails prevent the artificial grass grass from blowing up or shifting. After driving all the nails, make sure to brush up the artificial grass so that no artificial grass hairs remain under the nails. GRS Wire Nails NOT galvanized are supplied in 5 kg boxes and are always in sufficient stock.
