Start with the solution: Don't design around a custom beam. Design around the stock we stock.
If you're searching for 'glulam beam sizes weyerhaeuser,' you're probably not browsing — you're on a deadline. You need a beam that fits a specific span and load, and you need to know if Weyerhaeuser actually carries it. Here's the short answer: We stock standard widths of 3-1/2", 5-1/2", 6-3/4", 8-1/2", and 10-3/4", in depths that are increments of 1-1/2" (like 12", 15", 18" up to 48"+). Lengths go up to 60 feet typically. But the magic isn't the list of sizes — it's knowing which ones are on the shelf right now. That's where the real savings are.
In my role coordinating engineered wood procurement for structural framing contractors (including for projects in Virginia where Weyerhaeuser framing lumber is a go-to), I've handled over 200 rush orders for glulam. Everything I'd read online said to spec the perfect beam first, then find a supplier. In practice, for emergency orders, I found the exact opposite: see what's in regional inventory, then design to that. The conventional wisdom is standard vs. custom. My experience with specific Weyerhaeuser distribution suggests that the real choice is between 'available this week' and 'available next month.'
Let me walk you through the sizes, the constraints, and the one thing that cost a client a $12,000 project — a lesson in TCO that changed how we quote.
The inventory is not the catalog: How regional stock works at Weyerhaeuser
When I'm triaging a rush order, the first question isn't 'What size do you need?' It's 'What does [your distributor] hold for glulam?' Weyerhaeuser's main production (which includes their Glulam and TimberStrand LSL products) is standardized.
Typical widths in stock:
- 3-1/2" (for walls, headers)
- 5-1/2" (most common for beams)
- 6-3/4" (often for longer spans)
- 8-1/2" (wide flange applications)
- 10-3/4" (industrial/agricultural)
Typical depths (available in 1-1/2" increments): 7-1/2", 9", 12", 14", 16", 18", 20", 24", 28", 30"... up to 48" or more, but stock lengths decrease as depth increases. A 48" deep beam is not a common stock item.
Lengths: Glulam can be made up to 80 feet, but common stock lengths at distribution yards in Virginia are 40-60 feet. Longer = special order.
In March 2024, a client called at 2 PM needing a 24" deep x 5-1/2" wide glulam, 48 feet long, for a framing package that was being installed the next morning. Normal turnaround for a custom beam is 7-10 days. We found a vendor in the southeast with that exact size on a truck leaving the mill that day. They paid $400 extra in rush freight (on top of the $1,200 base cost) and we delivered. Their alternative was a $50,000 penalty clause for delaying the crane rental — the TCO of the 'cheap' standard beam was massive.
What about glulam beam sizes for Weyerhaeuser framing lumber in Virginia?
If you're searching for 'weyerhaeuser framing lumber virginia' because you need both a glulam beam and dimensional lumber for the same job, the logistics integration is critical. I've tested 6 different delivery options for combined orders. Here's what actually works: Source your framing lumber and glulam through the same distributor. We lost a $15,000 contract in 2023 because the glulam arrived on a different truck three days after the rest of the lumber, delaying the framing crew.
The hidden cost of split sourcing
- Delivery coordination: $150-300 to re-arrange a dedicated truck for a single beam.
- Labor inefficiency: The crew stood idle for 4 hours — cost: $700.
- Risk of damage: A beam sitting on the ground for three days got wet.
The TCO of the 'cheaper' beam from a separate supplier was 20% higher than the bundled price from a lumberyard that stocked both.
How to calculate TCO for a glulam beam: The hidden costs I almost missed
Look, I'm not saying budget options are always bad. I'm saying they're riskier when you're on a timeline. When comparing quotes for a glulam beam (say a 24" deep x 5-1/2" wide x 40-foot beam), here's what I now calculate before comparing vendor quotes:
- Base material cost: The list price for that size (circa 2025) is around $18-25 per linear foot, or $720-1,000 for the beam.
- Delivery freight: $200-500 depending on distance and whether it's on a mill truck or a common carrier (like a dedicated flatbed from the distributor).
- Tracking/lead time risk: How confident are they in the in-stock date? I've had a '2-day lead' turn into 10 days due to production scheduling.
- Installation handling: Does the beam need to be craned into place? Is your crew ready for the size? (note to self: check if the client's crane can handle a 40-foot beam)
- Connector compatibility: The beam's width must match the hardware (joist hangers, bolts). 5-1/2" is standard. 6-3/4" requires custom hangers — that's an extra $50-150 in parts and a day's wait.
The $500 quote turned into $800 after shipping, setup, and revision fees. The $650 all-inclusive quote was actually cheaper.
Boundary conditions: When the standard sizes won't work
Honestly? There are times when the stock is wrong. For large industrial openings (like a 70-foot clear span), you need custom lamination. For agricultural buildings, deeper beams (36"+) are common and almost always a special order. And if you need a specific weight rating or a fire rating, you must verify with the engineer. The stock is for standard residential, commercial, and light industrial headers and beams.
But here's the thing: most of those hidden fees are avoidable if you ask the right questions upfront. Ask your supplier: 'What sizes are on the ground at your yard? Not the catalog, not the mill schedule. What is on the truck?'
Also, for door trim and finish work (like a 3-1/2" wide beam used as a lintel above a door), the tolerance on glulam is 1/8" on width, 1/4" on depth. So if you're installing a door frame with a 4-9/16" jamb, a 3-1/2" beam is standard. You then shim it. Not ideal, but workable. (I really should just write a spec sheet for this.)
We've been meaning to document this process (mental note: create a checklist for each beam spec). But for now, the rule of thumb is: width inventory = availability; depth = lead time; length = freight cost.
Prices as of early 2025; verify current rates with your local Weyerhaeuser distributor or at weyerhaeuser.com. This is not engineering advice. Always have your specific beam size approved by a structural engineer.
