A mandrel for forming a metal framing member comprising: a shaped profile including four sides and two ends, wherein a first side and a second side are opposite each other and at least one of the first side or the second side extend away from the longitudinal axis of the profile at an angle,a plurality of small bearing micro rollers mounted on all four sides of the shaped profile,a metal strip, wherein the metal strip is positioned at a location on the mandrel where heat transfer is required, andwherein a third side and a fourth side are opposite each other and at least one of the third side or the fourth side extend away from the longitudinal axis of the profile at an angle. 3. A system for expanding a metal framing member comprising: a mandrel including:a shaped profile including four sides and two ends, wherein the a first side and a second side are opposite each other and at least one of the first side or the second side extend away from the longitudinal axis of the profile at an angle,a plurality of small bearing micro rollers mounted on at least one side of the shaped profile, anda set of pull-out rollers including a plurality of outer drive rollers and a plurality of inner drive rollers, wherein the plurality of outer drive rollers are arranged to pull a preformed tubular metal sheet over the mandrel. 4. A method of manufacturing a framing member comprising: producing two flanges on a metal sheet, wherein the metal sheet includes at least one pre-web region, at least two leg regions, four edges and a length, wherein the two edges are parallel to the length and each flange is on each of two of the edges;creating a plurality of slits in the at least one pre-web region of the metal sheet;expanding the plurality of slits in the at least one pre-web region to form at least one web region, the at least one web region including a web element and at least one web void wherein expanding the plurality of slits includes expanding when the metal sheet is at a temperature below about 100° C.; andforming the metal sheet including the at least one web region into a framing member, wherein during forming the metal sheet into a framing member a leg region is formed into a leg, and wherein the framing member consists only of the metal sheet and the framing member includes two legs and at least one web region, wherein the framing member includes a leg region formed from the two flanges of the metal sheet. 5. The method of claim 4, wherein forming the metal sheet into the framing member includes joining opposite edges of the metal sheet to form a tubular framing member. 6. The method of claim 5, further comprising joining the two flanges to form one leg of the tubular framing member. 7. The method of claim 6, wherein joining the two flanges includes welding the flanges to form the leg region. 8. The method of claim 5, wherein the tubular framing member includes two web regions. 9. The method of claim 4, further comprising modifying a portion of the metal sheet to include a reinforcement. 10. The method of claim 9, wherein the modified metal sheet consists of the metal sheet. 11. The method of claim 9, wherein modifying a portion of the metal sheet includes producing a flange, dimple or dart in the metal sheet. 12. The method of claim 9, wherein the portion of the metal sheet that is modified includes a leg region. 13. The method of claim 9, wherein the portion of the metal sheet that is modified includes a web region. 14. The method of claim 5, further comprising modifying a portion of the tubular framing member to include a reinforcement. 15. The method of claim 4, further comprising heat treating the framing member. 16. The method of claim 4, further comprising applying pressure to the leg regions to lengthen leg regions. 17. The method of claim 16, wherein the expanding the slits and applying pressure to the metal sheet occur substantially simultaneously. 18. The method of claim 4, wherein a leg region is substantially at the centerline of the metal sheet. 19. The method of claim 4, wherein expanding the slits in a pre-web region occurs in a direction which is different than a direction of translation of the metal sheet. 20. The method of claim 8, wherein a first web element from a first web region is joined to a second web element from a second web region. 21. A method of manufacturing a framing member comprising: creating a plurality of slits in the at least one pre-web region of a metal sheet, wherein the metal sheet includes at least one pre-web region, at least two leg regions, four edges and a length;forming the metal sheet into a framing member, wherein during forming the metal sheet into a framing member a leg region is formed into a leg, and wherein the framing member consists only of the metal sheet and the framing member includes two legs and at least one pre-web region; andexpanding the plurality of slits in the at least one pre-web region of the framing member to form at least one web region, the at least one web region including a web element and at least one web void. 22. The method of claim 21, wherein the framing member is a tubular framing member. 23. The method of claim 22, wherein the slits are expanded by being drawn over an internal mandrel inside the tubular framing member. 24. The method of claim 22, wherein the tubular framing member is heated. 25. The method of claim 24, wherein the leg regions are lengthened after the tubular framing member is heated. 26. A method of manufacturing a framing member comprising: producing two flanges on a metal sheet, wherein the metal sheet includes two pre-web regions, at least two leg regions, four edges and a length, wherein the two edges are parallel to the length and each flange is on each of two of the edges;creating a plurality of slits in the two pre-web regions of the metal sheet;expanding the plurality of slits in a first pre-web region to form a first web region, the first web region including a web element and at least one web void, wherein expanding the plurality of slits in the first pre-web region and expanding the plurality of slits in the second pre-web occurs substantially simultaneously;expanding the plurality of slits in a second pre-web region to form a second web region, the second web region including a web element and at least one web void, wherein expanding the plurality of slits in the first pre-web region and expanding the plurality of slits in the second pre-web occurs sequentially; andforming the metal sheet including the two web regions into a framing member, wherein during forming the metal sheet into a framing member a leg region is formed into a leg, and wherein the framing member consists only of the metal sheet and the framing member includes two legs and two web regions.
