PURPOSE:To provide the organism adhesion-preventing structure excellent in antifouling performance and durability, requiring no maintenance and free from toxicity by a simple sticking work. CONSTITUTION:A resin 2 comprising an electric insulating material is adhesively bonded to the inner circumferential wall surface of a cylindrical steel pipe 1. A metal net 5 comprising a beryllium-copper alloy is stuck on the surface of the resin 2. The thin plate 5 of the beryllium-copper alloy is drawn out from a plate product preliminarily rolled in a roll-like shape and subsequently adhesively bonded to the surface of the resin 2. The content of the beryllium in the beryllium-copper alloy is 0.2-2.8wt.%. The beryllium-copper alloy is selected from Be-Cu alloy, Be-Co-Cu alloy, Be-Co-Si-Cu alloy, Be-Ni-Cu alloy, etc. |
