       60 . A composite panel having first and second sides, the panel having complementary reinforcement forms at least partially embedded in set settable material or settable materials;
 wherein a first form or set of first forms, each form having at least one flange and having part or parts which
 i) extend from beyond one side, 
 ii) extend from one side, and/or 
 iii) extend from adjacent or nearer one side but within the panel, 
   
     laterally to said flange embedded at least substantially adjacent or nearer the second side but within the panel, and
 another second form or set of second forms, each form having at least one flange and having part or parts which
 i) extend from beyond the second side, 
 ii) extends from the second side, and/or 
 iii) extends from adjacent or nearer the second side but within the panel, 
 
 
     laterally to flanges embedded adjacent or nearer the first side but within the panel;
 wherein flanges of the first form and flanges of the second form have longitudinal axes substantially parallel; 
 and wherein the flanges of the first form and flanges of the second form interact, first form flange to second form flange, via the set settable material interposed therebetween, thereby to confer a structural or load bearing advantage to the composite panel. 
 
   
   
       61 . The composite panel of  claim 60  wherein the interaction via the interposed material is as a consequence of flange overlapping or near overlapping within the panel when one notionally considers the panel normally to a said side. 
   
   
       62 . The composite panel of  claim 60  wherein said interaction is without a flange of a first form touching a flange of a second form. 
   
   
       63 . The composite panel of  claim 60  wherein each form is elongate and the flange longitudinal axis is, or flange longitudinal axes are, parallel to the longitudinal axis of the form. 
   
   
       64 . The composite panel as claimed in  claim 60  wherein at least one of said first and second form is a metal form. 
   
   
       65 . The composite panel as claimed in  claim 64  wherein both of said first and second form is a metal form. 
   
   
       66 . The composite panel as claimed in  claim 60  wherein at least one of said forms is a sheet metal form. 
   
   
       67 . The composite panel of  claim 60  wherein there is at least one set of elongate forms as an array, each form of the array having a said flange from a said longitudinal part thereof. 
   
   
       68 . The composite panel of  claim 67  wherein said elongate form has the flanges as longitudinal lips to a lipped channel section elongate form. 
   
   
       69 . The composite panel as claimed in  claim 67  wherein there is lapping in part of individual flanges of one array with individual flanges of the other array when one notionally considers the panel normally to a said side. 
   
   
       70 . The composite panel as claimed in  claim 67 , wherein one array extends from one side or extends from adjacent or nearer one side but within the panel. 
   
   
       71 . The composite panel as claimed in  claim 67 , wherein both arrays extend from one side or extends from adjacent or nearer one side but within the panel. 
   
   
       72 . The composite panel as claimed in  claim 60  wherein there has been perforation and/or expanding of some part of at least one of the forms, or the material of the forms, to better mechanically tie to said settable material. 
   
   
       73 . The composite panel as claimed in  claim 60  wherein there has been, for at least one set as an array, some mechanical linking of the forms, one to another, prior to any at least partial embedding thereof. 
   
   
       74 . The composite panel as claimed in  claim 60  wherein said settable material is or includes at least one cementitious material. 
   
   
       75 . The composite panel as claimed in  claim 60  wherein the settable material is or includes a polymeric material. 
   
   
       76 . The composite panel as claimed in  claim 60  wherein said panel includes a mix of different settable material and one of said settable materials provides a surface over one of said sides. 
   
   
       77 . The composite panel of  claim 60  wherein there is said lapping of the flanges. 
   
   
       78 . The composite panel as claimed in  claim 60  that is lined. 
   
   
       79 . The composite panel of  claim 66  wherein said sheet metal forms are elongate and said flanges extend along parallel to the longitudinal axis thereof. 
   
   
       80 . The panel of  claim 60  wherein at least one of the sets is an array of mutually parallel elongate sheet metal forms. 
   
   
       81 . The panel  claim 80  wherein each elongate form has two flanges and each is in-turned to constrict the opening of a channel of a channel like section. 
   
   
       82 . The panel of  claim 60  where additional forms have been introduced to increase strength in some areas. 
   
   
       83 . The panel of  claim 60  wherein at least some of the embedded flanges are substantially flat and extend parallel to a face of said panel. 
   
   
       84 . The panel of  claim 60  wherein at least two individual sheet metal forms of a set, as an array are mechanically linked prior to the set of the settable material. 
   
   
       85 . The panel of  claim 60  wherein there is flange lapping and the lapping of individual flanges is such that along a face of a said panel, when notionally moving transversely to the preferred aligned longitudinal axis of roll or pressed elongate sheet metal forms, there is an alternating as a consequence of an offset of the arrays of which flange laps with which. 
   
   
       86 . The panel of  claim 60  wherein conduit forms pass between said arrays. 
   
   
       87 . The panel of  claim 86  wherein said conduit forms are embedded in said settable material. 
   
   
       88 . The panel of  claim 86  wherein conduit forms extend between said arrays substantially perpendicularly and/or obliquely to the elongate axis of the sheet metal forms.
