Demolition work generates scrap metal at a scale most other trades don’t — structural steel, reinforcement bar, cladding, pipework, and fixtures, often in volumes that make the difference between a marginal job and a genuinely profitable one.
What typically comes off a demolition site
- Structural steel — beams, columns, and framework, usually the largest-volume material by weight
- Reinforcement bar (rebar) — recovered from concrete, ferrous and consistently in demand
- Cladding and roofing — often aluminium or steel sheet, condition-dependent on price
- Copper and other non-ferrous fittings — pipework, wiring, and fixtures pulled during strip-out, lower volume but higher value per kilo
Why sorting at scale matters even more
On a small job, the time cost of sorting can outweigh the benefit. On a demolition site generating tonnes of mixed material, the value difference between sorted and unsorted scrap compounds fast — separating ferrous from non-ferrous, and higher-value non-ferrous materials from each other, at the point of strip-out rather than afterward.
Weight and logistics at scale
Unlike smaller trade jobs, demolition volumes usually justify direct collection logistics — a buyer coming to weigh and collect on-site, rather than transporting material yourself. This is also where getting multiple buyers to quote against the same job matters most, since the absolute value difference between offers scales with volume.
The enterprise angle
For contractors regularly running larger jobs, a single relationship with one buyer means accepting whatever rate they’re offering that month, even as market prices shift. Spreading volume across a competitive buyer base — or negotiating structured pricing for recurring volume — protects against this in a way a single-yard relationship doesn’t.
Getting started
Whether it’s a single site clearance or an ongoing programme of work, listing structural scrap for competitive offers rather than defaulting to one regular buyer is worth doing on every job, not just the largest ones.
