What is claimed is: 1. A method of producing a composite building component, said method comprising the steps of: (a) placing a first mat comprising a first wood-based material in a die set comprising an upper die and a lower die, and closing the dies to establish an upper outer zone die gap portio
What is claimed is: 1. A method of producing a composite building component, said method comprising the steps of: (a) placing a first mat comprising a first wood-based material in a die set comprising an upper die and a lower die, and closing the dies to establish an upper outer zone die gap portion lying in a first plane, a lower outer zone die gap portion lying in a second plane spaced apart from and below the first plane, and an angled zone die gap portion disposed between, contiguous with, and junctioned to said upper and lower outer zone die gap portions, wherein the upper outer zone die gap portion has a first die gap caliper that is less than second and third die gap calipers of the lower outer zone die gap portion and the angled zone die gap portion, respectively; (b) consolidating the first mat in the die set to form a first molded composite web having a first profile, the first profile comprising first outer zone having a first thickness consolidated in the upper outer zone die gap portion, a second outer zone having a second thickness consolidated in the lower outer zone die gap portion, and an angled zone having a third thickness consolidated in the angled zone die gap portion and disposed between, contiguous with, and junctioned to said first and second outer zones; (c) placing a second mat comprising a second wood-based material in the die set; (d) consolidating the second mat in the die set to form a second molded composite web having a second profile identical to the first profile; and (e) securing opposite end portions of the first and second molded composite webs to first and second end block beams, respectively, to establish a composite building component, wherein the first molded composite web opposes the second molded composite web in a reflectively symmetrical arrangement. 2. The method according to claim 1 wherein the second die gap caliper of said lower outer zone die gap portion is at least about equal to the third die gap caliper of the angled zone die gap portion. 3. The method according to claim 1 wherein the ratio of the first die gap caliper to the second and third die gap calipers is in a range of about 0.8 to 0.9. 4. The method according to claim 1 wherein the surface area of the first molded composite web is up to about 75% greater than the surface area of the first mat. 5. The method according to claim 4 wherein the surface area of the first molded composite web is about 15% to about 25% greater than the surface area of the first mat. 6. The method according to claim 1 further comprising: (f) joining a first flange to an outer surface of the first outer zone of the first molded composite web; (g) joining a second flange to an outer surface of the first outer zone of the second molded composite web; and (h) dividing the composite building component in a direction perpendicular to a direction in which the first and second outer zones extend. 7. The method according to claim 1, wherein the angled zone possesses a non-planar configuration. 8. The method according to claim 7, wherein the angled zone possesses a combination of planar and contoured portions. 9. The method according to claim 1, wherein the third caliper tapers from the lower outer zone die gap portion to the upper outer zone die gap portion. 10. The method according to claim 1, wherein the first and second webs have substantially uniform densities throughout. 11. The method according to claim 1, wherein said securing comprises adhesively bonding opposite end portions of the first and second molded composite webs to first and second end block beams, respectively. 12. The method according to claim 1, further comprising: (f) pressing the composite building component. 13. The method according to claim 1, wherein opposing outer zones of the first and second molded composite web contact one another. 14. The method according to claim 3, wherein said securing comprises adhesively bonding opposite end portions of the first and second molded composite webs to first and second end block beams, respectively. 15. The method according to claim 3, further comprising: (f) pressing the composite building component. 16. The method according to claim 4, wherein alternating outer zones of the first molded composite web contact corresponding alternating outer zones of the second molded composite web. 17. A method of producing a composite building component, said method comprising the steps of: (a) placing a first mat comprising a first wood-based material in a die set comprising an upper die and a lower die, and closing the dies to establish an alternating pattern of upper outer zone die gap portions lying in a first plane and lower outer zone die gap portions lying in a second plane spaced apart from and below the first plane, and angled zone die gap portions disposed between, contiguous with, and junctioned to said alternating upper and lower outer zone die gap portions wherein the upper outer zone die gap portion has a first die gap caliper that is less than second and third die gap calipers of the lower outer zone die gap portion and the angled zone die gap portion respectively, (b) consolidating the first mat in the die set to form a first molded composite web having a first profile, the first profile comprising first outer zones having a first thickness consolidated in the upper outer zone die gap portions, second outer zones alternating with the first outer zones and having a second thickness consolidated in the lower outer zone die gap portion, and angled zones having a third thickness consolidated in the angled zone die gap portions and disposed between, contiguous with, and junctioned to said first and second outer zones; (c) placing a second mat comprising a second wood-based material in the die set; (d) consolidating the second mat in the die set to form a second molded composite web having a second profile identical to the first profile; and (e) securing opposite end portions of the first and second molded composite webs to first and second end block beams, respectively, to establish a composite building component, wherein the first molded composite web opposes the second molded composite web in a reflectively symmetrical arrangement. 18. The method according to claim 17 wherein the second die gap caliper of said lower outer zone die gap portions is at least about equal to the third die gap caliper of the angled zone die gap portions. 19. The method according to claim 17 wherein the ratio of the first die B gap caliper to the second and third die gap calipers is in a range of about 0.8 to 0.9. 20. The method according to claim 17 wherein the surface area of the first molded composite web is up to about 75% greater than the surface area of the first mat. 21. The method according to claim 20 wherein the surface area of the first molded composite web is about 15% to about 25% greater than the surface area of the first mat. 22. The method according to claim 17 wherein said molded composite webs each has at least one channel defined by said alternating upper and lower outer zones, and said angled zones, and wherein said method further comprises: (f) joining a first flange to an outer surface of the first outer zones of the first molded composite web; (g) joining a second flange to an outer surface of the first outer zones of the second molded composite web; and (h) dividing the composite building component in a direction perpendicular to the channel. 23. The method according to claim 17, wherein the angled zones of the molded composite webs possess a non-planar configuration. 24. The method according to claim 22, wherein the angled zones possess a combination of planar and contoured portions. 25. The method according to claim 13, wherein the third caliper tapers from the lower outer zone die gap portions to the upper outer zone die gap portions. 26. The method according to claim 13, wherein the first and second webs have substantially uniform densities throughout.
