Roll-Off Container Service for Construction & Demolition Metal Waste

Every demolition job produces two piles: material you pay to bury, and material a buyer pays you for. Metal waste collection services for construction sites keep those piles apart. The EPA put U.S. construction and demolition debris at roughly 600 million tons in 2018, more than twice the volume of municipal solid waste. Metal is a small share of that tonnage, and it is one of the few streams a buyer pays you for instead of charging you to remove.

The container parked at your gate decides which pile grows. A box that fills with mixed debris becomes a disposal cost. A box that fills with clean steel and copper becomes a weight ticket and a payment.

What a roll-off container service includes

Roll-off container metal programs run on three standard sizes: 20, 30 and 40 cubic yards. Miami’s code defines a construction roll-off as an open metal container without wheels, with capacity up to 40 cubic yards, used to remove construction and demolition debris. Most boxes measure about 22 feet long and 8 feet wide, so plan the footprint before the truck arrives.

Weight sets the ceiling, not volume. A 40-yard box packed with rebar reaches legal truck limits long before it looks full. Florida caps trucks engaged in waste collection and operating as single units at 70,000 pounds gross, scale tolerances included, which is why General Metals sizes the box against the material, not the square footage for dense material instead of a bigger one.

Placement drives the rest. On private property the process stays simple. If the container sits on a street, sidewalk, swale or alley, a right-of-way permit applies, and Miami Beach requires location approval before that permit is issued.

 Miami-Dade also requires a general hauler permit for anyone collecting or transporting solid waste and recyclable material over public streets for hire or salvage. General Metals operates under Miami-Dade hauler permitting and confirms placement requirements before the box is dropped.

What construction and demolition metal is worth

Demolition splits into two families. Ferrous covers rebar, structural beams, joists, metal decking and stud framing. It sells by the ton at the lowest price per pound, and the money comes from volume. A single strip-out floor can produce more ferrous tonnage than the rest of the project combined.

Copper wire and pipe carry the highest value per pound, followed by aluminum window frames, conduit and flashing, then brass fittings and stainless. The London Metal Exchange sets the global reference price for non-ferrous metals, and COMEX copper trades alongside it. Domestic ferrous grades move with mill demand and regional indexes, so treat exchange screens as a market signal for steel rather than a payout table.

Grade decides the rest of the number. Bright copper pipe outprices insulated wire. Aluminum with steel screws still attached drops a grade. Motors, transformers and lighting ballasts get priced on their own, and steel with concrete still bonded to it costs the yard processing time you end up absorbing.

How to sort on a busy jobsite

Sorting works when it happens at the demolition face, not at the gate. Crews on Miami jobsites hold the rule when the boxes sit where the material comes down. Set one clean ferrous box near the demolition face and a smaller secured container for non-ferrous. Label both in English and Spanish. Walk the sorting rule at the morning huddle for the first three days, then it holds.

Cross-contamination is an expensive mistake. Miami’s ordinance states that mixing construction and demolition debris with other solid waste reclassifies the material as something other than C&D debris. The scale house applies the same logic. Wood, drywall and insulation in a metal box invite a grade downgrade or a sorting charge that erases the load’s margin.

Copper needs its own answer. Florida requires a signed ownership statement from the seller on every regulated metals transaction, which is why your foreman should carry project documentation. A separate and stricter category, restricted regulated metals, covers utility wire, manhole covers, guard rails and street signage, and those items require additional proof of ownership.

Scheduling swaps to match project phases

Metal arrives in waves. Structural demolition front-loads heavy ferrous. Mechanical, electrical and plumbing tear-out delivers copper and aluminum in short bursts. Interior strip-out produces light mixed metal over a longer stretch. Match the container to the wave instead of leaving one box on site for the full contract.

Track fill rate in the first 48 hours after delivery, then set the swap cadence from that number. A box loaded above the rails cannot leave legally, so overflow does not just look bad. It stops the truck, stops the crew, and pushes the next phase to the right. One truck hauls one open-top box per trip, which means swap slots need booking, not a phone call at 4 p.m.

Build the calendar around milestones. Clear metal ahead of concrete pours, before inspections, and ahead of storm staging in hurricane season. South Florida sites lose staging room fast once a system enters the forecast cone, and a full container in the wrong spot becomes a liability.

Salvage value and weight tickets

C&D metal recycling only pays when you can audit the transaction. A complete weight ticket shows gross weight, tare weight, net weight, the grade assigned and the price applied per grade. Keep every ticket with the job file the same way you keep concrete tickets.

Verify the scale. Florida law prohibits operating a weights and measures device for commercial purposes without a valid commercial use permit, issued through the Department of Agriculture and Consumer Services, so a certified scale is a documented condition rather than a marketing line. Ask what the tare was, and ask whether the tare came from that specific container.

Check the payment path too. Florida law requires payment above $1,000 for regulated metals property to be issued by check to the seller, and payment for restricted regulated metals by check or electronic transfer to the seller’s account. 

Compare your net value against the same-day exchange reference before you sign. Operations handling 600 tons or more of recovered materials in a year also face annual certification with Florida’s Department of Environmental Protection, so confirm where your volume lands.

Put scrap revenue in the bid, not in the cleanup budget

Contractors who price recovered metal at estimate stage carry a real advantage on tight bids. That only works when someone weighs the material honestly and pays for it on site.

General Metals Corp has been buying scrap in Miami since 1970, and family ownership across three generations is why the same people answer the phone on the second job as on the first. Containers come in 20, 30 and 40-yard roll-offs, plus EPA-compliant bins and drums for the copper and aluminum that carry your margin. Material gets weighed on FDACS-permitted scales, and payment happens on site, which Florida law allows for commercial vendors generating scrap in the ordinary course of business.

Coverage runs across Miami-Dade, Broward and Palm Beach. Tell us the phase, the square footage and the demo schedule, and a dedicated advisor prices the job against live market references before your first box is placed.
