Why the Scale and the Grade Sheet Determine What You Actually Get Paid
You haul a truckload of aluminum to a recycling yard and walk away thinking you got a fair deal. But did you? Most sellers don't fully understand how yards weigh and grade scrap — and that gap costs them money. Knowing the process gives you leverage. It also helps you ask better questions before the transaction closes.
Whether you're dropping off a few hundred pounds or moving a full load, the aluminum scrap price today you see posted on a board or quoted over the phone is just the starting point. What the yard actually pays you depends on how they weigh the material, what grade they assign it, and how those two numbers interact. This guide breaks it down clearly so you never leave value on the floor.
How Recycling Yards Weigh Your Scrap Metal
Most established yards use a certified platform scale — often called a drive-on or truck scale — that captures the gross weight of your vehicle loaded, then the tare weight (vehicle empty), and calculates the net weight of your material. That net weight is what you get paid on. For smaller loads, portable bench scales or floor scales handle the job.
Here's what you should know before you pull up to the scale:
- Wet material adds weight you won't get paid for. Aluminum tubing with standing water inside, steel coated in ice or mud, or soggy cardboard mixed into a bin all inflate gross weight. Yards will often deduct for moisture or simply pay on estimated dry weight.
- Tare weight is measured when you leave empty. If you add or remove anything from your vehicle between the two weigh-ins, the math breaks down. Don't do it.
- Scales must be certified. In Quebec, provincial weights and measures regulations require commercial scales to be inspected and certified. If a yard's scale looks ancient and uncalibrated, that's a concern worth raising.
- Ask for a weight ticket. Every legitimate yard prints one. It shows gross, tare, net, date, and material type. Keep it.
Sellers in Trois-Rivières dealing with yards across the Mauricie region should always request that weight ticket before the grade conversation starts. Weight and grade are two separate negotiations, and you want documentation for both.
Understanding Scrap Metal Grades — And Why They Move the Price
Grading is where yards have the most discretion — and where sellers leave the most money behind. The grade assigned to your aluminum, copper, steel, or other metal determines which price tier applies. Two loads of "aluminum" can fetch very different rates depending on how the yard classifies them.
For aluminum specifically, common grades in the North American market include:
- Clean aluminum extrusion (6063 alloy): Window frames, door frames, clean profiles with no inserts, paint, or attachments. This is one of the higher-value aluminum grades.
- MLC (Mixed Low Copper) / Painted aluminum: Coated or painted extrusion. Lower value because the coating contaminates the melt.
- Cast aluminum: Engine blocks, transmission cases, wheels. Typically valued differently than extrusion because the alloy composition differs.
- Irony aluminum: Material with significant steel contamination — bolts, brackets, inserts still attached. Yards heavily discount this because they have to separate it before processing.
- Old Sheet Aluminum (OSA): Flashing, roofing panels, gutters, siding. Middling value, fairly consistent market.
- UBC (Used Beverage Cans): The classic aluminum can stream. Valued separately, usually at a lower per-pound rate than extrusion but easy to move in volume.
The aluminum scrap value per pound can vary significantly across these grades. Checking the aluminum scrap price today without knowing which grade applies to your material gives you an incomplete picture. Before you find the best Canadian scrap metal prices today, identify what grade your material most likely falls into.
What Yards Are Actually Looking For When They Grade Your Load
When a yard employee walks your load, they're making a fast judgment call based on a handful of factors. Understanding those factors helps you prepare your material better — and push back intelligently if you think a grade is wrong.
Contamination is the primary grading factor. Steel in aluminum, plastic in copper, rubber in wire — any foreign material reduces the grade. Spend time before you arrive stripping attachments, separating alloys, and cleaning your loads. A cleaner load earns a better grade. It's that straightforward.
Alloy identification matters for non-ferrous metals. A yard grader may use a handheld XRF analyzer (a metal composition gun) on higher-value loads to confirm alloy type. This is common for copper, brass, and stainless. For aluminum, visual inspection combined with XRF gives a more accurate grade — but not every yard has this equipment, especially smaller operations in regional markets.
Physical condition also factors in. Shredded, bent, or heavily oxidized material is harder to process and may attract a lower grade. Intact, sorted material is easier to handle and typically commands better terms.
If you're operating in Trois-Rivières or anywhere in Quebec and want to compare what multiple buyers would pay for a graded load, platforms like SMASH let you put your documented inventory in front of vetted buyers simultaneously. That's how competitive pricing works — not one phone call, one opinion, one number.
How to Prepare Your Scrap to Maximize Your Grade — and Your Payout
Most sellers treat prep as an afterthought. The yards that pay the best prices in markets like Trois-Rivières prefer sorted, documented loads because it reduces their processing cost. You lower their cost, they pay more. That's the trade.
Here's a practical prep checklist before you haul:
- Sort by metal type. Aluminum with aluminum, copper with copper. Mixed loads get graded at the lowest denominator.
- Remove steel fasteners and attachments. Bolts, screws, brackets — they're fast to remove and significantly affect your aluminum grade.
- Drain fluids. Engines, radiators, and other liquid-containing components need to be drained. Many yards won't accept fluid-containing parts, and it's an environmental compliance issue.
- Photograph your load before it leaves your facility. Especially for larger loads. If a grading dispute happens, documentation helps.
- Know your material. Can you identify the alloy? Do you have any product documentation — spec sheets, purchase records, BOLs? More information gives buyers more confidence and supports a better grade.
SMASH's inventory documentation tools are built for exactly this kind of preparation. Photo documentation, serial tracking, and detailed lot descriptions give the vetted buyers on the platform more confidence — and more confidence typically means stronger bids. To check current Canadian scrap metal prices and understand what your graded material might be worth, start with current market data before you approach any buyer.
Why Selling to One Buyer Is the Biggest Pricing Mistake You Can Make
Here's the uncomfortable truth: if you're calling one yard, getting one quote, and accepting it, you don't know if you're getting a fair price. You're getting a price. Those are different things.
The old way — one buyer, one phone call, one number written on a weight ticket — worked when there were no better options. That's no longer the case. The best scrap metal prices in Trois-Rivières and across Quebec aren't found at a single yard. They're found when multiple buyers compete for your load. Competition is the mechanism that reveals actual market value.
This is what SMASH is built on. No subscription fees. No lock-in. You only win when the seller wins. Vetted buyers bid on your documented load, and you can see the competition in real time. For anyone serious about getting the best scrap metal prices Quebec and across Canada, that transparency is worth more than any single relationship with a single yard.

Frequently Asked Questions
Q: How do I know if a recycling yard's scale is accurate?
In Quebec, commercial scales used for trade must be certified under federal and provincial weights and measures regulations. Ask to see the certification sticker on the scale. Every legitimate yard will have one. If you're unsure, always request a printed weight ticket that documents gross, tare, and net weight for your records.
Q: What is the aluminum scrap price today in Trois-Rivières?
Aluminum scrap prices fluctuate daily based on LME (London Metal Exchange) aluminum spot prices, local supply and demand, and the specific grade of your material. Prices vary between clean extrusion, cast, sheet, and irony aluminum. Check best-scrap-metal-prices.ca for current Canadian market rates before heading to a yard or submitting a load for auction.
Q: What's the difference between aluminum scrap value per pound for clean extrusion versus cast aluminum?
Clean 6063 aluminum extrusion typically commands a higher per-pound rate than cast aluminum because it has a more consistent, higher-purity alloy composition. Cast aluminum (engine blocks, wheels) contains other alloying elements that affect its melt value. The gap between these grades can be meaningful, so identifying your material correctly before selling matters.
Q: Can I sell scrap metal online from Trois-Rivières?
Yes. Platforms like SMASH allow sellers across Canada to document their inventory and connect with vetted buyers through a competitive auction format — without being locked into one local yard's price. This is particularly useful for larger loads of non-ferrous metals where even a small per-pound improvement makes a real difference to your payout.
Q: Why does my scrap get graded lower than I expected?
The most common reasons are contamination (steel, plastic, or other metals mixed in), moisture or coatings on the material, and unremoved attachments like fasteners or brackets. Sorting your material carefully, stripping attachments, and keeping loads clean before you haul will almost always result in a better grade — and a better price per pound.
