Claim:
A structural sandwich plate member comprising: a first outer metal plate including a left side plate and a right side plate and a second outer metal plate; an unfoamed polyurethane elastomer core bonded to said outer metal plates with sufficient strength to transfer shear forces therebetween; and a rolled or extruded edge member fitted between and connected to said first and second outer metal plates and extending along at least a part of the periphery of said outer metal plates and said profile providing a weld location suitable for welding said structural sandwich plate member to another structural sandwich plate member, said edge member comprising: a web extending perpendicularly to said first and second outer metal plates and having a first end and a second end, and a first flange disposed intermediate the first and second ends, the second end being welded to said second outer metal plate, the web extending from said second end to said first flange in contact with said polyurethane elastomer core, wherein the first flange is substantially parallel to said first outer metal plate in contact with said polyurethane elastomer core and welded to surfaces of said left side plate and said right side plate of said first outer metal plate that face the second outer metal plate, the web extending from said first flange in a direction away from said polyurethane elastomer core and perpendicularly to said first metal plate beyond said first flange and said first and second outer metal plates to said first end.
