Abstract
The present invention relates to a polyolefin-covered steel product and more particularly to a polyolefin-covered steel product, for use in a steel structure, having excellent impact resistance, flaw resistance and resistance to abrasion by littoral drift. The polyolefin-covered steel product comprises a steel product which has been subjected to surface treatment, and having laminated onto the treated surface, a modified polyolefin resin layer and a polyolefin resin layer, characterized in that the surface of the polyolefin resin layer is further covered with a fiber cloth to which a modified polyolefin resin has been laminated.
