The reinforced concrete element in in-situ concrete or as a prefabricated component, which can be freely selected according to the customer's requirements, serves as a collision guard or also as a filler wall for bulk fill storage facilities. As an economical support structure, the frame can be placed on this angle support wall. Roof purlins and wall rails, for example in wood, form the load-bearing construction for roof and wall cladding. As roofing material, the corrugated fibre cement board makes a good alternative to steel roofing, and is an advantage due to its fibre-optic plates, which can be easily arranged, and its low condensation formation. An ecological wall panelling in wood or weather-resistant trapezoidal sheet, round out the entire package for shelters and bulk fill storage facilities.
