G-Tech have now started offering factory installed white lines highlighting the coper edge. The lines are applied using a Chlorinated rubber paint in White and applied to a 100mm depth from the leading edge. The paint being applied in the factory alleviates one of the jobs required normally after installation and a job often affected by the poor British weather including rain, humidity or temperature. This method allows the paint to be applied indoors at a set temperature and without requiring any possessions or other rail industry restrictions normally encountered at site. The lines are applied across the width of the coper and the cement line between copers can then be hand painted with the same white paint from a mini pot supplied by G-Tech when the copers are ordered.
