TECHNICAL SECTIONStructural Design Guidelines — StandardIndividual profile length and load requirements should not exceed the curve in any load example. If this occurs, choosea profile with a larger section modulus to stay below the curve.Load Condition:Load at centerLoad at centerLoad at endSpanFixed at both ends,load at centerSpanFixed at one end, sliding at one end,load at centerSpanFixed at one end,load at unsupported endLoad in lbs (P)7000650060005500500045004000350030002500200015001000y = Deflection In InchesPLy=36.26 x 10 9y=PL 33.38 x 10 9PLy=39.24 x 10 8PLy=34.65 x 10 8Load in lbs (P)7000650060005500500045004000350030002500200015001000y = Deflection In Inches2900y = Deflection In Inches2700y=PL 33.5 x 10 9250023002100PL 32.60 x 10 8 700y=1900PL 1700y=1.89 x 10 91500y=9.78 x 10 7PL 3y=PL 35.17 x 10 813005.28 x 10 71100y=y=PL 3900500y=300Load in lbs (P)PL 31.44 x 10 7PL 37.26 x 10 65005001005 10 20 30 40 50 60 70 80 90 100 110 120Span in inches (L)5 10 20 30 40 50 60 70 80 90 100 110 120Span in inches (L)5 10 20 30 40 50 60 70 80 90 100 110 120Span in inches (L)PIC-STIXProfile Part Number SX3030 SX1530 SX1530 SX1515 SX1515LMoment of Inertia-in 4 3.26 .481 1.173 .242 .108Section Modulus-in 3 2.173 .641 1.76 .323 .1363 O ** Angle is 1 O on SX1010L, SX1015L, SX1515L,and SX1545LAll PIC-STIX extrusions have a 1 or 3 degreedecline from extrusion edge to slot centerline.When fasteners are properly tightened, thefeature serves as a lock mechanism to keepthem tight.1.51.5 1.51.5 1.51.51.51.5.75.25.75Standard mounting and connecting bracketshave clearance holes for 5/16" dia. connectingscrews which are all on .75" and 1.5"centers.PIC fastener brackets, extrusions, hardwareand accessories provide an unlimited systemfor structural design and assembly.Suggested Applications■ SX1010L (1" x 1") — LightIdeal for machine guards, enclosures, anddisplays.■ SX1015L (1" x 1 1 /2") — LightEnclosures, benches.■ SX1515L(1 1 /2" x 1 1 /2") — LightLight load bearing structures, guarding andlightweight support frames.■ SX1515 (1 1 /2" x1 1 /2") —Medium load bearing structures, a goodcombination of structural strength in acompact size.■ SX1530 (1 1 /2" x 3") —Used for larger and stronger structures andmachine frames. The center of this extrusioncan be used to run air or electrical lines.■ SX3030 (3" x 3") —For larger structures where maximumstrength is desired The center of theseextrusions can also be used to run air orelectrical lines.9-2Phone: 800-243-6125 ■ FAX: 203-758-8271E-Mail: sales@pic-design.comDESIGN®www.pic-design.comInteractive catalog ■ CAD ■ e-commerce
