Single iron wheels are one-piece cast or forged iron — no separate core, no bonded tread — carrying up to 18,000 lb per wheel. The one-piece construction is the point: nothing to delaminate, nothing to debond, just solid iron rated for the heaviest single-wheel transfer.
Bonded-tread wheels have a failure mode single iron doesn't: the tread can debond from the core under heat, impact, or sustained extreme load. A single iron wheel is one material throughout, so that failure can't happen. At 18,000 lb per wheel, eliminating a failure mode is worth the trade-offs — and the trade-offs are real: single iron is the harshest wheel on floors and transmits all shock to the load.
Steel mill and foundry transfer, large machine and die movement, rail systems, and any extreme-duty application where the floor is steel, embedded rail, or distribution-plated — and where uptime matters more than ride quality. For extreme load on a finished floor, polyurethane-on-forged-steel is the alternative.
Single iron is one-piece — no debonding risk, harshest on floors. Metal-core adds a polymer tread for floor protection at some capacity cost.
Steel rail, embedded track, or distribution-plated paths. It will damage standard concrete under sustained load.
Powered — a four-wheel set at 18,000 lb each totals 72,000 lb. Tugger or tow vehicle, sized to the load.
