The invention is applicable to such building elements as concrete or lightweight concrete slabs, beams, columns which can be pre-formed or pre-cast or can be formed in situ. The present invention also relates to mesh which can be utilised as reinforcing for the application of a fire rating material to building elements such as beams of steel or concrete or slabs of concrete, or other building services elements such as air-conditioning duct work or airflow duct work. The invention also relates to a method of manufacturing such mesh and a method of applying a fire rating material to such building elements and or building service elements. The invention also relates to a mesh panel which is prefabricated and manufactured at a factory for transport to a location for installation and for application of a fire rated material or product, as well a method of making ducts and or building risers and ducts or building risers made by these methods.WO 2014/019015 PCT/AU2013/000789 31/36 o 0 t0 0 r-4 r
