The claim from Cromweld Steels is simple – the use of an economical stainless steel and polystyrene pre-fabricated building system for commercial, residential and industrial buildings results in construction that is cheaper, faster, stronger, and more versatile than any other wall panel system including wood frame or concrete block.
The components are also simple - a 4-5 inch core of non-CFC expanded polystyrene, clad with 3.2mm welded 3CR12 stainless steel mesh and coated with the desired thickness of concrete or plaster. The lightweight panels are placed over 3CR12 rebar in a concrete foundation and fastened to one another with 3CR12 wire mesh reinforcing seams and corners. Windows and door openings can be cut for any type of framing material and electrical conduit and plumbing are placed between the mesh and the foam.
The resultant monolithic structure has been tested to show that the system is adaptable to virtually any structural requirement or climatic, environmental and seismic condition. It offers design flexibility and adapts easily to curved or arched design applications and little equipment is needed for installation. Labour costs are also dramatically reduced as specialised fitters, framing, masonry, insulation and drywall trades are all largely eliminated.
The system also has significant environmental benefits. It is an excellent thermal and sound barrier and the component materials are environmentally intelligent. 3CR12 is recyclable, the polystyrene does not contain CFCs and it is an inherently passive solar design.
Applications include commercial office buildings, factories, warehouses, low-cost housing, sound barrier, fire and partition walls.
