2 PLANKS sit on frames and are subjected to the affronts of rain, snow, heat, cold, heavy loads, and wear from numerous erection and dismantle cycles. SCAFFOLD companies need PLANKS they can rely on PLANKS that have minimal twist and bow after that type of exposure. iLevel Trus Joist Heavy Commercial has the solution: SCAFFOLD PLANKS made of MICROLLAM laminated veneer lumber (LVL). MICROLLAM LVL SCAFFOLD PLANKS are safe and reliable, and have predictable at iLevel are committed to working safely and want to remind you to do the same.

4 These properties apply only to MICROLLAM laminated veneer lumber (LVL) SCAFFOLD PLANKS used in conditions where the moisture content of the plank is not expected to exceed 19%. These values apply only to PLANKS used in the flat orientation. Fb, E, and Fv shall be adjusted by a factor of when used in conditions where the moisture content of the plank is expected to exceed 19%. Fastener values (nails, bolts, screws) shall be as provided for sawn Douglas fir per 2001 National Design Specification for Wood Construction (NDS ) or per Canadian Standards Associations (CSA) O86-01, Engineering Design in Wood.

5 No increases in allowable unit stresses are included for load-sharing systems.

6 A comparison of engineering data on MICROLLAM laminated planking with engineering data on planking of SCAFFOLD grades, as indicated in the West Coast Lumber Inspection Bureau Grading Rule, finds that MICROLLAM laminated planking provides the equivalent strength of SCAFFOLD grade planking, and meets the equivalent requirements in (a)(10).This is not to be construed as either an approval or an endorsement of the product. This determination is contingent upon the product continuing to meet the specified engineering criteria which was J.

10 Spans shown are considered the distance between the center lines of bearers. Actual MICROLLAM LVL SCAFFOLD plank lengths will be greater due to overhangs or overlaps specified in ANSI Contact iLevel Trus Joist Heavy Commercial for additional span information. Two-span values assume both spans have equal lengths. Contact iLevel Trus Joist Heavy Commercial when the two spans do not have equal lengths. Uniform and person loads shown are defined in ANSI Proper MICROLLAM LVL SCAFFOLD plank selection must be based on the most restrictive load case anticipated when PLANKS are in IDENTIFICATIONT here are many grades of MICROLLAM laminated veneer lumber (LVL).
