UK Manufactured Lead Stampings — Discs, Washers & Bespoke Pressed Forms
Heaps, Arnold & Heaps Ltd manufactures lead stampings at our Rotherham facility for UK and international engineering, plumbing, electroplating, marine and industrial maintenance sectors. With over 250 years of lead manufacturing experience, we press lead discs, lead washers and fully bespoke pressed components from refined lead sheet — in diameters from 5mm up to 200mm+, in thicknesses from 1mm to 10mm, with pierced holes, slots and shaped profiles formed in a single stamping operation.
Cold-pressed lead stampings offer a faster, more dimensionally consistent and more cost-effective alternative to cast lead components for high-volume small parts — particularly where surface flatness, hole positioning or repeatable thickness tolerances matter.

Lead Stamping Capabilities & Dimensions
Diameter Range
- 5mm – 25mm — small washers, sealing discs and miniature components
- 25mm – 75mm — standard washers, flange seals and general engineering components
- 75mm – 200mm — large discs for shielding, ballast and industrial sealing
- 200mm+ — bespoke large-format stampings to drawing
Thickness Range
- 1mm – 3mm — light gauge for small washers and sealing applications
- 3mm – 6mm — standard gauge for engineering washers and gaskets
- 6mm – 10mm — heavy gauge for shielding discs and structural components
- Custom thicknesses available outside the standard range
Features Formed in a Single Operation
- Pierced central holes — concentric or offset, single or multiple
- Slotted apertures — round, rectangular or shaped slots
- Shaped outer profiles — non-circular outer edges to drawing
- Multiple-feature parts — holes, slots and shaped outers combined in one stamping
Forming features in a single operation gives better dimensional consistency than secondary machining and significantly reduces unit cost on high-volume runs.
Standard Lead Stampings
Lead Washers
The most commonly specified lead stamping. Used wherever a soft, conformable, corrosion-resistant washer is required:
- Plumbing sealing washers — for traditional flange and union jointing in heritage plumbing
- Flange gasketing washers — high-pressure sealing where lead’s malleability fills surface imperfections
- Electrical bonding washers — soft lead for earthing and grounding connections
- Vibration damping washers — between mating surfaces to reduce resonance and noise
- Anode connection washers — for electroplating tank bus bars (see also our chrome plating anodes and cathodic protection anodes)
Lead Discs
Solid lead discs without central piercing. Used for:
- Sealing discs — flange and valve seat sealing
- Shielding discs — small-area radiation shielding for equipment apertures
- Counterweight discs — for fine balancing of rotating equipment and scientific instruments
- Ballast discs — incremental weighting in industrial and marine applications
- Acoustic damping discs — sound deadening in machinery enclosures
Bespoke Pressed Forms
Non-standard pressed lead components produced to customer drawing:
- Custom-shaped seals and gaskets
- Pressed lead components for specialised equipment
- Replacement parts for obsolete or unobtainable original components
- Multi-feature pressed parts with complex hole patterns and profiles
Lead Stamping Applications
Plumbing & Pipework Sealing
Lead washers remain a specified component for heritage plumbing restoration, traditional flange jointing and high-quality industrial pipework sealing. Lead’s malleability allows it to deform under torque and fill surface imperfections in the mating flange — creating a permanent leak-tight seal that doesn’t relax over time. Supplied to:
- Heritage and Listed building plumbing contractors
- Traditional plumbing supply merchants
- Industrial pipework sealing specialists
- Heating system installers for traditional cast-iron systems
See also our lead tubes, sleeves and pipes and traditional industrial solders for the related product range.
Industrial Sealing & Gasketing
Lead gaskets and sealing washers are specified for high-pressure flange jointing, vacuum equipment, chemical processing pipework and specialist industrial sealing where standard rubber or fibre gaskets are unsuitable:
- High-pressure steam and condensate systems
- Chemical processing equipment with corrosive media
- Vacuum equipment flange sealing
- High-temperature industrial pipework
- Specialist research and laboratory equipment
Vibration & Acoustic Damping
Lead’s high density and internal damping properties make it an effective vibration isolation material. Lead washers placed between mating surfaces absorb vibration, reduce resonance and lower transmitted noise. Used in:
- Industrial machinery installations
- Compressor and pump mounting assemblies
- Acoustic enclosure construction
- Marine engine mounting
- Scientific instrument vibration isolation
Electroplating & Anode Connections
Lead washers are used in electroplating tank construction to connect anodes to bus bars, providing a low-resistance electrical contact that resists tank chemistry corrosion. Specified by:
- Electroplating shops — chrome, tin, nickel and specialist plating
- Cathodic protection installers
- Industrial OEM in-house plating facilities
See also our lead, chrome and tin electroplating anodes industry overview.
Radiation Shielding & Equipment Apertures
Small lead shielding discs are used to fill apertures, equipment penetrations and observation port shielding in medical and nuclear installations. See our lead shielding bricks and rails for the standard shielding range, and our medical radiation shielding and nuclear applications industry overviews.
Heritage & Restoration
Pressed lead components for vintage car restoration, traditional engineering equipment refurbishment and heritage machinery maintenance — including replacement washers, seals and bespoke pressed parts matched to original specifications. See our lead products for automotive restoration overview.
Bespoke Lead Stampings
Many of our stamping orders are bespoke. For pressed components outside our standard range, we manufacture bespoke lead stampings at our Rotherham facility:
- Custom diameters and thicknesses outside the standard ranges
- Complex hole and slot patterns formed in a single operation
- Non-circular outer profiles — square, rectangular, irregular shapes to drawing
- Multi-feature pressings combining several geometric features
- Specialist alloy compositions — antimonial, tin/lead, custom blends
- Replacement parts matched to obsolete or sample components
How Bespoke Orders Work
- Send drawings, samples, or a clear description of the stamping required
- We review feasibility and provide a quote with lead time and any tooling cost
- On approval we produce, inspect and dispatch with documentation
For one-off prototypes and small quantities we can typically work without dedicated tooling. For volume production runs, tooling may be required — included in the quote and amortised across the production volume.
