Prefabricated panel for roofs-wall - having corrugated metal core plate, hard smooth facing plate, outer flapped membrane

摘要

Prefabricated building panel for roofs and walls has a composite core having an intermediate part with longitudinal corrugations, and carrying on one side a facing plate with a hard, smooth, load-bearing surface. A weather-resistant membrane layer covers the outer face of the facing plate, and has a flap on >=1 edge for placing over a similar adjacent building panel. High quality panels can be produced rapidly at low cost. Good resistance to weather and loads. Easily mounted and maintained. Can be sawn, drilled, screwed and cut on site. A variety of types can be produced, according to the building requirements, e.g. different shapes, weights, strengths and thermal insulation props.
