1. A frame structure for a switch cabinet, said frame structure comprising at least four vertically extending rail profiles; andat least one of said vertical rail profiles comprising:a cross section formed by a plurality of bent profile webs, the bent profile webs of the cross section fitting within an imaginary rectangular envelope defined by a plurality of edges forming a perimeter of said envelope, at least some of the bent profile webs coincident with one of said perimeter edges of the rectangular envelope;said at least one vertical rail profile configured to be open; andat least one double walled profile web extending for a length which is greater than a length of one of the perimeter edges of the rectangular envelope. 2. A frame structure in accordance with claim 1, wherein said length of said double-walled profile web is greater than a length of each of said perimeter edges of said rectangular envelope. 3. A frame structure in accordance with claim 1 wherein said perimeter is substantially square. 4. A frame structure in accordance with claim 1 wherein said double-walled profile web subdivides said at least one vertical rail profile into a section facing an interior of said switch cabinet in the mounted state and into a section facing away from the interior of said switch cabinet in the mounted state. 5. A frame structure in accordance with claim 1 wherein said at least one vertical rail profile in cross section comprises a first pair of profile webs positioned at an angle relative to each other and forming an edge of said rail profile facing an interior of said switch cabinet in the mounted state, and said cross section further comprises a second pair of profile webs positioned at an angle relative to each other and forming an edge of said rail profile facing away from the interior of said switch cabinet in the mounted state. 6. A frame structure in accordance with claim 5 wherein said profile webs of each of said first and second pairs of profile webs are positioned at about a 90° angle relative to one another. 7. A frame structure in accordance with claim 5 wherein, when viewed in cross section, the angles enclosed between the first and second pair of profile webs define adjacent corners of said rectangular envelope and also define a section of a single side wall of said at least one vertical rail profile. 8. A frame structure in accordance with claim 5 wherein, when viewed in cross section, said double-walled profile web extends between the first and second pair of said profile webs up to a corner of said envelope, said corner being adjacent the first pair of profiled webs facing the interior of said switch cabinet. 9. A frame structure in accordance with claim 8 wherein each wall of said double-walled profile web is connected to a respective one of said first and second pairs of said profiled webs. 10. A frame structure in accordance with claim 1, some of said profile webs defining a side wall of said vertical rail profile, said double-walled profile web integrally formed with said profile webs defining said side wall. 11. A frame structure in accordance with claim 9 wherein, when viewed in cross section, said double-walled profile web extends from said side wall at an angle of about 60° from the side wall. 12. A frame structure in accordance with claim 1 further comprising a laterally projecting fastening web formed on said double-walled profile web. 13. A frame structure in accordance with claim 12 wherein said laterally projecting fastening web extends substantially parallel to one of the perimeter edges of the rectangular envelope. 14. A frame structure in accordance with claim 13 wherein said laterally projecting fastening web extends in a direction facing away from an interior of said switch cabinet in a mounted state. 15. A frame structure in accordance with claim 12 wherein said lateral fastening web is double-walled. 16. A frame structure in accordance with claim 1 wherein one of said profile we bs faces an interior of said switch cabinet in a mounted state, said profile web facing the interior of said switch cabinet extending about half a length of the corresponding perimeter edge length of said rectangular envelope. 17. A frame structure in accordance with claim 1, wherein some of said profile webs define a side wall of said vertical profile rail, each of said profile webs which define said side wall having a different length extending along one of said perimeter edges of the rectangular envelope, an innermost one of said profile webs which define said side wall extending toward the interior of said switch cabinet in a mounted state being longer than an outermost one of said profile webs which define said side wall extending away from an interior of said switch cabinet in a mounted state. 18. A frame structure in accordance with claim 1, wherein said plurality of bent profile webs includes a first profile web and a second profile web which define a single side wall of said vertical rail profile, said first profile web and said second profile web having a length ratio of about 2/1. 19. A frame structure in accordance with claim 1 wherein one of said profile webs extends toward an exterior of the switch cabinet in a mounted state, said profile web extending toward the exterior being less than half as long as a corresponding perimeter edge length of said rectangular envelope. 20. A frame structure in accordance with claim 19 wherein said profile extending toward the exterior of said switch cabinet has a length about ⅓ of the corresponding perimeter edge of said rectangular envelope. 21. A frame structure in accordance with claim 5, wherein said second pair of profile webs have an approximately equal length. 22. A frame structure in accordance with claim 12 wherein some of said profile webs define a side wall of said vertical rail profile, said side wall including a first profile web having a first length and a second profile web having a second length which is less than said first length, said lateral fastening web having a third length greater than said second length and less than said first length. 23. A frame structure in accordance with claim 5 wherein said first pair of profile webs are each provided essentially over their whole length with at least one row of holes. 24. A frame structure in accordance with claim 23 wherein said at least one row of holes includes alternating round and rectangular holes. 25. A frame structure in accordance with claim 12 wherein said lateral fastening web is longitudinally provided with at least one row of holes. 26. A frame structure in accordance with claim 12 wherein said lateral fastening web is oriented away from an interior of said switch cabinet in a mounted state, said lateral fastening web longitudinally provided with at least one row of holes. 27. A frame structure in accordance with claim 12, wherein said double-walled profile web and said double-walled fastening web are each formed by folding two wall sections of said profile webs onto one other. 28. A frame structure in accordance with claim 1 wherein said at least one said vertical rail profile is integrally made from sectional steel. 29. A frame structure in accordance with claim 1 further comprising at least one horizontal profile designed as an open profile.
