PRE-COATED CORROSION-RESISTANT STEEL PIPE PILE FOR MARINE USE

摘要

A steel pipe pile for mains use is provided with outstanding resistance to corrosion and scratching by precoating with a polyethylene resin material, preferably including carbon black and an anti-oxidant, at least over the splash zone and tidal zone. The coating may be extended to the riprap layer or further. Otherwise electrical corrosion protection or a corrosion allowance may be provided beneath the coating.
