You ask two suppliers to quote the same 18 ft x 4 ft x 12 in mat. One comes back at $700. The other says $1,400. Same size, same units, same word on the quote. So which one is lying?

Probably neither. They're quoting two different products, and the quote doesn't tell you that. Comparing timber mat prices fairly means putting every quote on the same footing first. Here's how contractors can do that without getting burned.

Why the Same Size Doesn't Mean the Same Mat

Dimension tells you volume. It tells you nothing about strength. Two mats with identical outside measurements can differ in bending strength, measured as modulus of rupture (MOR) in PSI, by 300 percent or more depending on species and grade.

That matters on a live job. One of those mats carries a heavy crane's outrigger load with margin to spare. The other is working close to its limit, or past it. A quote that lists only size and price is a marketing claim with a number attached, not a specification.

A real quote answers four things: species, grade, material strength, and measured dimension. If any of those are missing, you aren't comparing mats yet. You're comparing guesses.

Step 1: Pin Down the Species and Grade

There are roughly 20 commercial species used across the mat industry, and "hardwood" on a quote tells you almost nothing. Typical numbers look like this:

• Oak: around 550 PSI bending strength at #2 grade, closer to 1,000 PSI at #1
• Mixed hardwood: roughly 550 to 1,000 PSI, because the label covers whatever species a mill had on hand
• Eucalyptus: closer to 2,000 PSI, about double a #1 oak mat

"Mixed hardwood" is a marketing term, not a technical category. Treating it as a fixed price tier is how buyers end up comparing two "mixed hardwood" quotes that aren't remotely the same product. Mats are practically built to three grades, #1, #2, and #3, so ask which one you're actually getting.

Step 2: Check That the Mat Measures True

A true timber is 5 inches by 5 inches or larger. Anything smaller is lumber, and a mat built from a mix of timbers and undersized lumber isn't a real timber mat, no matter how the invoice describes it.

Thickness matters even more than most buyers expect, because capacity scales roughly with the square of thickness. A 12-inch mat that measures 11 inches in hand loses close to a sixth of its rated capacity (144 versus 121). That's a mat quietly downgraded before it touches the ground.

So ask whether the quoted dimension is nominal or measured, and check it with a tape measure on delivery. A true 48-inch width, 8 or 12-inch thickness, and 16 or 18-foot length is what you're paying for. Often it isn't what shows up.

Step 3: Look at Hardware and Build Quality

Crane mats typically run 12 inches thick and should use Grade 36 bolts or better. Some mills cut cost on hardware, especially with steel prices where they are. Ask whether timbers are square cut or rounded, and whether end plates are used. Square timbers grip each other more solidly and wear more evenly. A mill cutting corners here is a mill you'll be calling again sooner than you want to.

Step 4: Ask Who Actually Made It

A manufacturer can usually trace a mat back to its species, grade, and often the forest it came from. A reseller is frequently selling whatever was available at the cheapest price that week, and may not be able to answer the species question at all.

Neither model is automatically wrong. But you should know which one you're buying from before you trust the rest of the quote. A useful test: ask for a documented MOR rating on the specific lot you're buying, not a general range for the species.

Step 5: Add Freight, Because the Quote Usually Doesn't

Mill-gate pricing leaves out a real cost. Freight runs roughly $1,500 or more per truckload, and weight decides how many mats fit on each one. A 12-inch Eucalyptus load fits around 11 mats per truck, against roughly 10 for a comparable mixed hardwood load. At $1,500 per truck, that's about $136 per mat versus $150, before distance and fuel surcharges.

Always ask for freight cost per mat, landed at your site. It's the only number you can compare line for line.

Step 6: Convert Everything to Cost Per Month

This is the step that changes the answer. Purchase price tells you almost nothing about what a mat costs you over a project. Lifespan does, and lifespan depends on everything above, plus rot, which is the leading long-term failure mode for most wood mats. Eucalyptus is the exception.

Here's the comparison on an 18 ft x 4 ft x 12 in mat, using industry cost data (CIP Houston):

The cheapest mat on day one is the second most expensive per month. Add the freight figures above and the gap widens, to roughly $22 versus $55 per mat-month for Eucalyptus and mixed hardwood. Those landed numbers are a simple calculation from the figures in this article, so run your own against real quotes.

Cheaper on day one and more expensive every month after that isn't a bargain. It's deferred cost.

Where Contractors Overpay

Length they can't use. Twenty-foot mats are the length most often quoted, but the extra length rarely adds effective bearing under a crane. Buyers defaulting to 20 feet often pay a 10 to 20 percent premium for length that does no work. Fourteen, sixteen, and eighteen-foot mats cover the large majority of crane applications.

Rush orders. A same-week request often gets filled from whatever inventory sits closest to spec, not the best spec for your job. Ordering 60 to 90 days before mobilization gives a mill room to cut to your requirement.

Buying on price per mat. It's the easiest number to compare and the least useful.

A Quick Checklist Before You Pick a Quote

Get these in writing from every supplier:

• Species, grade, and documented MOR rating in PSI
• Measured dimensions, confirmed at delivery
• Hardware grade and construction method
• Freight cost per mat, landed at your site
• Expected service life for your site conditions
• Lead time for the first order and for repeat orders on the same spec

A quote missing any of these isn't incomplete by accident. It's incomplete because the number looks better that way.

What It Comes Down To

Comparing timber mat prices fairly takes a few extra questions and a little arithmetic, and it can change which supplier wins. Put every quote on the same spec, add freight, and convert to cost per month. If you want help running the numbers on your own project, World Forest Group's total cost of ownership calculator does the math across price, lifespan, and freight.

Frequently Asked Questions

Why do timber mat quotes vary so much for the same size?

Because size isn't the specification. Species, grade, true measured dimension, and hardware all change both the price and how the mat performs, so identical dimensions can hide very different products.

What's the best way to compare timber mat prices?

Convert each quote to cost per mat-month. Divide the landed price (mat plus freight) by expected lifespan in months. It puts short-life and long-life mats on the same scale.

Is the cheapest mat ever the right choice?

Sometimes, for short, light-duty, one-off jobs. For heavy crane loads, multi-phase projects, or rot-prone sites, a lower upfront price usually costs more per month.
