How to Source Scrap Metal
Before any scrap gets listed and sold, it has to come from somewhere. Here's where it actually comes from, and the etiquette that keeps sourcing legal and repeatable.
Most people who start selling scrap assume the hard part is finding a buyer. It usually isn't — the hard part is finding a steady supply worth listing in the first place. Below are the six sources that consistently produce sellable scrap, roughly ordered by how reliable they are once you've built a relationship with them.
Demolition and renovation sites
Demolition crews often just want material gone — copper pipe, structural steel, aluminium siding, rebar. Ask the site foreman directly rather than the crew; most sites have someone with authority to say yes, and many are happy to hand off metal to save on disposal costs. Never take anything without asking, even if a site looks abandoned.
Manufacturer and machine-shop offcuts
Metal fabrication shops generate offcuts and shavings every day that they usually pay to have hauled away. A standing arrangement to collect for free (or at a small fee that still beats their disposal cost) can turn into a reliable weekly source once you've built the relationship.
Estate cleanouts and moving sales
Old appliances, radiators, and metal furniture show up constantly at estate sales and cleanouts, often priced to move fast. Arrive with a truck and cash and you can often negotiate scrap-value pricing on items the seller just wants gone.
Municipal bulk-pickup nights
Most cities schedule a night or two a month for large-item collection. Old grills, appliances, and furniture with metal frames appear on curbs the evening before. This is legal in most places once items are set out, but confirm your specific city's rules on early collection.
Auto salvage and end-of-life vehicles
A dead car is a genuinely large scrap lot — steel body and frame, aluminium wheels and engine parts, a catalytic converter, copper wiring, a lead-acid battery. Salvage yards will often let you strip a vehicle for parts in exchange for the metal, or you can arrange directly with someone scrapping their own car.
Businesses that would otherwise pay for disposal
Restaurants (stainless equipment), offices (old furniture, filing cabinets), warehouses (racking, pallet frames) frequently pay a hauler to remove old metal fixtures. Offering free removal is an easy pitch — you save them the disposal fee, you keep the metal.
Where the legal line actually is
Ask before you take anything that isn't clearly abandoned or set out for collection. Never remove wiring, pipe, or fittings from a structure that's still in use, even if it looks unused from the outside — active utility infrastructure and occupied buildings are the two things that turn "scrapping" into theft, and it happens more often than people think when someone assumes a building is vacant.
Sorting before you list
Once you've got material, sort it before you even think about listing. Mixed loads price at the lowest common grade — one bin of clean copper wire sells for far more per kilogram than the same copper thrown in with steel and aluminium. Separate by:
- Ferrous vs non-ferrous (a magnet test takes ten seconds and settles it)
- Insulated wire vs bare-stripped wire — bare-bright pays noticeably more
- Clean metal vs painted, plated, or coated metal — coatings reduce the payable weight
- Whole appliances/motors vs stripped components, if you have time to strip them
Common Questions
Is it legal to take scrap metal from the curb?
In most places, yes, once it's set out on bulk-trash collection night — but check your municipality's rules first, since some cities restrict scavenging before the official collection truck arrives, and a few require a permit. If it's in someone's driveway or yard and not clearly set out for collection, ask before you take it.
What's the most valuable scrap metal to source?
Copper (especially clean, bare-bright copper wire) and brass typically pay far more per kilogram than steel or aluminium, which is why they're worth the extra time to sort and strip cleanly rather than dumping everything in one mixed load.
Do I need insurance or a license to collect scrap as a side income?
For casual, small-scale collection, most places don't require a license. Once you're regularly hauling from businesses or handling larger volumes, check local regulations — some jurisdictions require scrap dealers (not casual sellers) to register, mainly to prevent stolen-metal resale.
How do I avoid buying or collecting stolen metal?
Never take wiring, pipes, or fittings still connected to an active structure, and be wary of anyone offering large volumes of clean copper at an unusually low price with no explanation of where it came from — that's the classic profile of stolen material.
