Lead: Metal of the Month

Lead is one of the oldest engineered metals, used continuously since the Bronze Age. Its combination of high density, low melting point, corrosion resistance, malleability and radiation-shielding capability gives it a wide range of industrial, construction and specialist applications. At the UK weighbridge, lead consistently ranks among the highest per-kilo rates of any common metal, driven by the closed-loop recycling chain that returns recovered lead to secondary smelters and back into new battery and roofing production. The UK lead-acid battery recycling rate exceeds 99%, one of the highest closed-loop rates of any waste stream.

What Lead Actually Is

Lead is a soft, dense, bluish-grey metal with the chemical symbol Pb and atomic number 82. It has a density of 11.3 grams per cubic centimetre, roughly 1.5 times that of steel, and a low melting point of 327°C. Lead is malleable, corrosion-resistant in air and water, and provides effective shielding against ionising radiation. UK industry uses lead in lead-acid batteries (the dominant application), roof flashing and weatherproofing, plumbing solder and (historically) pipework, radiation shielding in medical and industrial settings, ammunition, and weights and ballast.

Where It Comes From

UK lead scrap arises from automotive end-of-life batteries (the largest single stream), industrial standby and traction batteries, roof-flashing replacement on heritage and church buildings, lead pipework strip-outs from older properties, lead-clad cable from telecoms decommissioning, decommissioning of radiation shielding from medical and industrial sites, weight and ballast from marine and industrial applications, and historic lead came from stained-glass windows. Plumbing lead is generally pre-1970s; modern UK plumbing uses copper, plastic or composite.

How We Grade It

UK scrap yards grade lead into distinct categories. Lead-acid batteries constitute a hazardous waste stream under EWC 16 06 01 and the Hazardous Waste Regulations 2005, with specific handling and consignment-note requirements. Sheet lead (roof flashing, cladding) settles at a clean lead rate. Lead pipe is the historic plumbing grade. Lead cable sheathing is recovered from stripped power and telecoms cables. Lead solder is a specialty grade. Mixed lead captures items for which the specific category is unclear. Each grade has distinct handling and settlement; lead-acid batteries are routed through hazardous-waste-licensed receiving bays.

What Contaminates a Load

For lead-acid batteries: cracked or leaking units mixed with intact stock, mixed chemistries (lithium-ion absolutely must not be mixed in), acid contamination on the exterior, and loose, unprotected terminals all create handling, safety and grading issues. For sheet lead and pipe lead: nail and fixing contamination, paint residue, and mortar and roofing felt attached. The most expensive contamination for any lead load is mixed-chemistry battery loads, which can trigger fire risk and entire-load rejection.

What Affects the Price

Lead pricing tracks the LME lead contract, quoted in US dollars per tonne. UK weighbridge settlement accounts for the grade, contamination level, the sterling exchange rate and the LME-secondary spread. Sheet lead and pipe lead settle at clean lead rates; lead-acid batteries settle at a battery-specific rate reflecting the additional hazardous-waste processing required. The price gap between clean sheet lead and unsorted mixed lead loads is significant.

Bring It to Dunmow

We accept all grades of lead at our three Essex weighbridges: Chelmsford, Colchester (Brightlingsea), and Clacton. Lead-acid batteries are handled through our hazardous-waste-licensed bays at the Chelmsford metals facility, with full consignment-note paperwork. Lithium-ion batteries are not accepted as general scrap. For ongoing trade volumes, open a trade account, and we will deliver RoRo containers or dedicated battery containers to site.
