Mercer Glulam Beams
Widths published as 3 in, 5 in, 6.75 in, 8.5 in, 10.25 in, 12.25 in, 14.25 in, 15.875 in and 18 in. Depth given by the formula nlam x 35 mm - 6 mm, with western species at nlam 4-34 normal and 35-63 specialty, southern species at nlam 4-31 normal. Appearance grades Architectural (AA), Industrial (IA) and Premium. Manufactured at Conway and Okanagan. The page states calculations follow NDS 2024. CSI: payload said 06 17 00 and NO RETRIEVED MERCER PAGE PRINTS A CSI NUMBER, so the payload value is kept rather than replaced with a guess. NOTED: run 699 established from Nordic Structures ICC-ES ESR-4874 that glulam addresses at 06 18 00 (Glued-Laminated Construction), a DIFFERENT DIVISION-06 SECTION FROM THE CLT ROW. Another manufacturer document, so recorded as the likely refinement, not applied. A later run with a Mercer document that prints a CSI should split these two rows to 06 17 19 and 06 18 00 respectively.

Certifications & Standards
What was checked, and what is deliberately not claimed
- Nds_not_linked
- The page states calculations follow NDS 2024. The NDS is a design standard used by the engineer of record, not a manufacturing or identification requirement imposed on the product, and no NDS provision is held in this corpus. Recorded, linked to nothing.
- Conjunctive_gap
- *** THE GOVERNING SECTION IS CONJUNCTIVE AND ONLY HALF OF IT IS EVIDENCED. IBC 2021 2303.1.3 reads "Glued-laminated timbers shall be manufactured and identified as required in ANSI/APA 190.1 and ASTM D3737." The manufacturer names ANSI A190.1 and DOES NOT NAME ASTM D3737 on any permitted page. ASTM D3737 is the practice for establishing allowable properties, and A190.1 does invoke it in practice - BUT THAT IS AN INFERENCE ABOUT HOW THE STANDARDS RELATE, NOT SOMETHING THE MANUFACTURER STATED, and filing it would be asserting a citation the manufacturer never made. It is left unclaimed and is the second ask in letter 133. ***
- Note_on_ranking
- Contrast the CLT row on the same manufacturer, same session: there the code section names ONE standard and the manufacturer names it, so the match is complete. Here the code section names TWO standards joined by AND and the manufacturer names one. SAME MANUFACTURER, SAME QUALITY OF PAGE, DIFFERENT STRENGTH OF MATCH - and the difference is entirely a property of how the two code sections are written. Worth recording as a general point: the strength of a designation match is set as much by the grammar of the code section as by the manufacturer.
- No_fire_rating_claimed
- No fire-resistance rating, char rate or tested assembly is published for these beams and none is claimed.
