Document Type and Number:
Japanese Patent JP2019178358
Kind Code:
A
Abstract:
To provide a coating anticorrosion structure of a structural steelwork keeping enough thickness of a plastic layer, keeping adhesion of the coating anticorrosion structure and using a petrolatum-based anticorrosion material.SOLUTION: In a petrolatum-cover anticorrosion method, a coating anticorrosion structure of a structural steelwork comprises a rustproofing layer containing a petrolatum-based anticorrosion material on the surface of the structural steelwork, a plastic layer outside of the rustproofing layer, and a protective layer outside of the plastic layer.
