1. A three piece component (1, 51) comprising: a main body (5, 50) having two stiles (3, 65) and at least one central panel member (4, 56) intermediate to and integrally formed with the two stiles (3, 65),wherein each of the stiles comprises a protruding portion,wherein the central panel member comprises four corners,at least one end of the main body (5, 50) defining an opening (6, 59) in the main body (5, 50) where each of the stiles (3, 65) extend beyond the panel member (4, 56) forming the protruding portions and at least one rail (2, 81) being formed for insertion into the opening (6, 59) at the end of the main body (5, 50),wherein the main body further comprises a short beveled portion (54) extending between a location proximal to each of the corners of the central panel member (4, 56) and a location along internal surfaces (57) of each of the protruding portions defining the opening (6, 59),each said short beveled portion (54) having an edge (61) and each of said protruding portions having an edge (63) proximal to a front visible surface (52) of the three piece component, wherein a visible intersection between the edge (61) of each said short beveled portion (54) with the edge (63) of the opening defining said internal surfaces (57) of said stiles (65) defines a sharp rectilinear intersection angle (66) with no internal radius and wherein the opening comprises an undercut (73) formed in each of said stiles (65) proximal to the intersection of the edge (61) of the short beveled portion (54) with the edge (63) of the opening defining said internal surface (57) of each of said stiles (65), the undercut (73) allowing a specially designed cutting tool to be buried into each of said stiles (65) so as to form the edge of the short beveled portion as a true rectilinear edge (61) forming a sharp rectilinear intersection angle (66). 2. The three piece component (1, 51) as claimed in claim 1, wherein said rail (2, 81) is formed for insertion in said opening (6, 59) between the protruding portions of the stiles (3, 65). 3. The three piece component (1, 51) as claimed in claim 1, wherein the main body (5, 50) is substantially H-shaped. 4. The three piece component (1, 51) as claimed in claim 1, wherein the sharp rectilinear intersection angle (66) is an angle in the range of 120° to 150°. 5. The three piece component (1, 51) as claimed in claim 1, wherein the undercut (73) is formed a short distance below the front visible surface surface (52) of each of said stiles (65). 6. The three piece component (1, 51) as claimed in claim 1, wherein said rail comprises two rails, said rails (81) each having two short beveled portions (82) formed for mating engagement with the beveled portions (54) of the opening (59) to create beveled joints. 7. The three piece component (1, 51) as claimed in claim 6, wherein beveled surfaces (87) of the short beveled portions (82) of said rail (81) taper at a slight angle from the front visible surface (52) towards a rear hidden surface (53). 8. The three piece component (1, 51) as claimed in claim 7, wherein the taper comprises an angle in the range of 1° to 5°. 9. The three piece component (1, 51) as claimed in claim 1, wherein beveled surfaces (71) of the short beveled portions (54) defining the opening (59) in the main body (50) taper at a slight angle from the front visible surface (52) towards a rear hidden surface (53) of the three piece component. 10. The three piece component (1, 51) as claimed in claim 9, wherein the taper comprises an angle in the range of 1° to 5°.
