The QB 30F-E3 and “QB RIM” are glued laminated timber (glulam) products.
The QB 30F-E3 2.1E 650Fc^ Glulam beams are used as beams, headers, rafters, or purlins. They are manufactured with a proprietary balanced layup combination documented in the in-plant manufacturing standard. QB 30F-E3 glulam beams use conventional laminating lumber grades of Douglas fir – Larch in the tension and compression zones and Southern pine in the core. The outermost tension and outermost compression laminations are made of laminated veneer lumber (LVL), as permitted by ANSI A190.1. The LVL laminations are supplied by manufacturers recognized by APA and identified in QB’s in-plant manufacturing standard approved by APA. The LVL complies with the control values listed in the manufacturing standard and is manufactured in full-length and width laminations and net thicknesses of 1-1/2 inches from wood veneers. All veneer grain is parallel to the length of the billets. The LVL is bonded with another LVL or lumber laminations using exterior-type adhesives in compliance with ANSI 405. QB 30F-E3 glulam beams have a minimum depth of 7-1/4 inches and a maximum depth of 48 inches.
As for “QB RIM” it is a glulam rim board manufactured in accordance with ANSI A190.1 using Combination 1 (L3/DF) and then resawn to a specific thickness without re-grading. The depth of QB RIM shall be 20 inches or less.
Please note that these products are subject to specific building codes and standards, so it is always recommended to consult with a structural engineer or professional before using them in a project.
