How to prepare scrap metal for sale by cleaning sorting cutting weighing and storing

Prepare scrap for sale by sorting it with a magnet, removing the steel, brass and plastic attachments that downgrade a load, cutting steel to the yard’s charge size, draining fluids and keeping material dry, and bringing photo ID plus proof of ownership for vehicles, converters and cable. A prepared load is paid at the top of each grade; a mixed one at the bottom of the lowest.

The yard grades what it sees, and it sees a load for about a minute. Preparation decides what that minute shows.

Set up before you start

  • Bins or bags for copper, brass, aluminum, stainless, lead, heavy steel and light steel.
  • A magnet, a file, side cutters, a hacksaw or reciprocating saw and an angle grinder for stubborn joints.
  • Gloves, eye protection, toe-capped boots and a mask for grinding.
  • A bathroom or luggage scale to check weights against the yard ticket.

Sort with the magnet first

Everything that sticks hard goes to the ferrous side. Everything that does not is sorted by colour and weight into copper, brass, aluminum and lead.

Anything heavy, silver and only slightly magnetic is checked as stainless. The ferrous vs non-ferrous guide explains the exception.

Remove what downgrades a load

  • Copper pipe: cut off brass valves, fittings and steel clamps, and cut out soldered joints for number 1 rather than number 2.
  • Aluminum frames: remove steel screws, hinges, rollers and plastic thermal breaks.
  • Wheels: take off tyres, weights and valve stems.
  • Radiators: cut off steel brackets and plastic tanks.
  • Wire: strip heavy cable, leave thin cord alone, and keep bare and insulated wire apart.

Cut to the yard’s size

Mills charge scrap of a set size and yards pay less for anything they must shear. Plate and structural steel usually needs to be under about 1.5 by 0.6 metres; ask your yard for its limit.

Cutting a long beam into three pieces at home can move it from a low grade to plate and structural.

Drain and dry

Oil, coolant, water and fuel are deducted as moisture or refused. Drain engines and gearboxes, tip water out of pipe and radiators, and keep cans and turnings under cover.

Sealed containers such as gas cylinders and fire extinguishers are refused everywhere; ask the yard how it wants them handled.

Appliances and refrigerants

Refrigerators, freezers, air conditioners and dehumidifiers contain refrigerant that must be recovered by a licensed technician before scrapping. Yards ask for a tag or certificate and refuse untagged units in most countries.

After recovery, the compressor, copper tubing and aluminum fins can be sold on the non-ferrous side.

Vehicles, converters and cable

A car needs its title or registration and, in many countries, proof of deregistration. Pull the battery, catalytic converter, aluminum wheels, radiator and any reachable copper wiring before the car goes on the scale.

Copper cable and anything that could have come from infrastructure needs proof of origin. A licensed yard refuses it without one.

Paperwork and payment

Bring photo ID. The United Kingdom, France, Belgium and the Netherlands pay by transfer only; most US and Australian states record ID and pay by cheque for theft-prone items; commercial sellers in India should bring GST details. The country pages list the rules for each market.

At the scale

  • Load heavy ferrous first and non-ferrous bins last, so bins can be weighed separately.
  • Watch the scale zero and confirm the tare is measured.
  • Read the ticket: one line per grade with weight, price and any deduction.
  • Photograph the load and the ticket.
  • Compare each line with the live board before you accept payment.

Key numbers

  • Removing fittings from copper pipe typically moves it from number 2 to number 1, a difference of 5 to 10 percent on the price (Recycled Materials Association grade definitions).
  • Aluminum with steel attached is bought as irony aluminum, often at less than half the clean extrusion price (published yard price lists).
  • In the United States, refrigerant must be recovered by a certified technician before an appliance is scrapped (US EPA Section 608).
  • Moisture and dirt deductions of 2 to 10 percent are common on wet or oily loads; a covered, drained load avoids them (published yard terms).

Questions people ask

Do I really need to cut the fittings off copper pipe?

If you want the number 1 price, yes. Brass fittings and soldered joints drop the pipe to number 2 or to the brass price, and the cut takes seconds per joint on anything over a few kilograms.

Will a yard take my old fridge?

Only after the refrigerant has been recovered by a licensed technician and the unit is tagged. Most yards refuse untagged cooling appliances, so arrange recovery first or use a council collection.

What paperwork do I need to scrap a car?

The title or registration in your name and, in many countries, proof of deregistration. Bring photo ID as well, and expect the yard to record the vehicle identification number.

Common mistakes

  • Loading non-ferrous bins under the ferrous so they cannot be weighed separately.
  • Bringing a fridge or air conditioner without a refrigerant recovery tag.
  • Leaving oil and water in engines, radiators and pipe.
  • Cutting cable spools or utility metal without proof of origin.
  • Accepting a ticket with one weight and one price for a mixed load.
