Copper strip or pipe arrangement, for prevention or destruction of plant, moss or algal growth on tiled roofs, has perforated copper pipes that release copper ions in rain

摘要

The arrangement has a number of copper pipes, rails or rods (3,4), which are perforated along their entire length and periphery. The copper metal reacts with moisture to release copper ions. The copper ions are separated when it rains and destroy or remove plant growth. The pipe profile (5) may be U-shaped, round, triangular, rectangular or polygonal.
