UK Lead Ballast Blocks Supplier — Counterweights Cast to Any Size
Heaps, Arnold & Heaps Ltd is a UK lead ballast blocks supplier, manufacturing cast lead ballast and counterweights at our Rotherham facility for the marine, offshore, subsea, lift, crane, automotive, broadcast and industrial sectors. With over 250 years of casting experience, we cast ballast blocks and counterweights to any reasonable size and weight specification — from small precision balance weights up to multi-tonne marine ballast.
Lead’s high density (11.34 g/cm³) means lead ballast delivers more mass per unit volume than virtually any practical alternative, making it the standard choice where space is constrained but mass is critical.

Marine Lead Ballast UK — Vessel & Subsea Applications
Marine lead ballast UK applications are some of our most common ballast supplies. Lead ballast is used throughout the marine and offshore sectors where weight density, corrosion resistance and dimensional stability matter:
Vessel Ballast Applications
- Yacht and sailing vessel keels — encapsulated lead keel castings
- Pleasure craft trim ballast — adjusting vessel balance and stability
- Commercial vessel ballast — fixed and movable ballast installations
- Working boat trim weights — fishing vessels, pilot boats, workboats
- Submarine and submersible ballast — buoyancy and trim control
Offshore & Subsea Applications
- Subsea structure ballast — holding subsea installations on the seabed
- Pipeline weight coatings — concrete-encapsulated lead weights for pipeline stability
- ROV and AUV ballast — buoyancy adjustment for underwater vehicles
- Diving weight systems — commercial diving equipment
- Subsea cable weights — holding power and communication cables in position
- Mooring system clumps — anchor and mooring ballast
See our dedicated Lead Products for Marine, Offshore & Subsea page for the full marine product range.
Lead Counterweights — Lift, Crane & Industrial
Lead’s high density makes it the preferred material for lead counterweights manufacturer applications where mass needs to fit into restricted space:
Lift Counterweights
- Passenger lift counterweight blocks
- Goods lift counterweight stacks
- Lift modernisation replacement counterweights
- Bespoke geometries for non-standard lift well dimensions
Crane Counterweights
- Mobile crane counterweight blocks
- Tower crane counterweight elements
- Workshop crane and hoist counterweights
- Industrial gantry crane balance weights
Industrial Counterweight Applications
- Theatre rigging counterweights — stage fly system balance
- Broadcast equipment counterweights — camera jib and crane balance
- Industrial machinery counterweights — press, punch and forming equipment
- Window and door counterweights — heritage building maintenance
- Test rig and laboratory ballast
Automotive & Restoration Lead Ballast
Lead ballast and counterweights are widely used in automotive engineering, motorsport and restoration applications:
- Vehicle balance ballast — for race vehicles meeting minimum weight rules
- Trailer tongue weights — for towing stability
- Classic vehicle restoration — replacing original lead components
- Vintage commercial vehicle ballast — for working restoration vehicles
- Suspension test weights — for engineering development
See our Lead Products for Automotive Restoration page for related restoration applications.
Custom Castings & Bespoke Ballast
Standard ballast blocks rarely fit complex requirements. For projects requiring specific geometries, we cast to your drawings or samples:
Bespoke Capabilities
- Drawings-based production — anodes manufactured to your engineering specification
- Sample-matched casting — replicating existing components
- Integrated handling features — lifting eyes, handles, slots, holes
- Pre-finished surfaces — painted, encapsulated, rubber-coated
- Steel-encased ballast — for impact-resistant or protected installation
- Multi-piece ballast stacks — modular ballast systems
- Concrete-cast lead weights — for pipeline and marine installations
How Bespoke Orders Work
- Send us drawings, samples, or a clear description of what you need
- We review feasibility and confirm any tooling requirements
- Quote provided with lead time (typically 2–4 weeks depending on complexity)
- On approval we cast, inspect, finish (if required) and dispatch
- Repeat orders fulfilled from established tooling on shortened lead times
Lead Ingots & Standard Blocks
For applications where the geometry isn’t critical, we supply standard cast lead ingots and blocks:
- Standard ingots — typically 12kg and 25kg cast bars
- Cube blocks — standard sizes for stacking and modular use
- Slab castings — flat slabs for distributed ballast
- Pig lead — primary lead castings for re-melting
These are typically supplied to lead processors, downstream casters and industries using lead as raw material rather than as finished ballast.
Material Quality & Documentation
All our ballast products are:
- Cast at our UK facility from documented source materials
- Available in pure lead or specified alloy compositions
- Batch-numbered for traceability
- Weighed to confirm specification before dispatch
- Supplied with documentation suitable for marine survey, lift inspection or industrial compliance records
For marine and offshore ballast, certification of UK origin and material composition simplifies due diligence and approval processes — particularly for installations subject to classification society survey (Lloyd’s, DNV, ABS etc).
