  • Thin walled shaped body and method of producing same
    Patent number: 4619857
    Abstract: Thin walled shaped bodies, specifically profiled building elements, which bodies are made of a hydraulically set material, comprise at the outer surface thereof a preferably strip shaped reinforcement at least at the area of the highest tensile load, e.g. at the wave trough of a corrugated board, which reinforcement is bodily and materially bonded to the shaped body. Such shaped bodies have a greatly improved strength for high loadings, such as e.g. in an application for building elements forming covering or roofing members.
