Black Cast Iron Olympic Weight Plates
Black Cast Iron Olympic Weight Plates 50mm Centre Hole | 1.25kg to 25kg | Slim Profile Design
Our black cast iron Olympic weight plates are built for lifters who want the classic feel, sound, and loading capacity of traditional iron. The slim profile means more plates fit on the sleeve than an equivalent rubber coated plate, which matters once you're loading heavy for squats, deadlifts, or bench press.
Each plate is manufactured with a precise 50mm Olympic centre hole, so it fits standard Olympic barbells, EZ bars, and adjustable dumbbell handles without play or wobble. Whether you're setting up a home gym, garage gym, or fitting out a PT studio, these plates give you a straightforward, durable option for building your weight library.
Below you'll find the full specification, honest pros and cons, and everything you need to know before ordering.

Why Choose Cast Iron Plates
Engineering and Finish
These plates are cast from solid iron and finished in a black hammertone coating, chosen for its resistance to scratching, chipping, and general wear from daily gym use. The 50mm centre hole is machined to a consistent tolerance so plates load and unload smoothly without excess play on the sleeve, and the raised grip lip reduces strain when loading and stripping the bar during heavy sessions.
Frame weight tolerance is held to ±3% across the range. Plate dimensions per weight and country of manufacture are To confirm.

Pros and Cons

- Durable hammertone finish suited to daily use
- Classic iron feel and sound preferred by many serious lifters
- Consistent weight accuracy for reliable programming
- Accessible price point across the full weight range
- Not designed for overhead dropping, Olympic lifting, or CrossFit style releases
- Louder on the bar and on the floor than rubber coated or bumper plates
- Can mark or damage unprotected flooring if dropped
- No colour coding, so plates are identified by size rather than colour at a glance
Who Is This For
-
Home gym ownersBuilding a strength training setup without the extra cost of rubber coated plates.
-
Powerlifters and strength athletesWho want maximum loading capacity within a limited sleeve length.
-
Garage gym owners on a budgetWho need a durable, no-frills weight plate solution.
-
PT studios and small commercial gymsWanting a classic iron plate option alongside rubber coated stock.
-
Lifters upgrading from adjustable dumbbellsMoving into barbell training with a full Olympic plate set.
Who should not buy these: if you regularly drop plates from overhead in Olympic lifting or CrossFit style training, our rubber coated or bumper plate range is a better fit. If you want a colour coded system for fast visual weight identification, rubber coated plates will suit you better than plain cast iron. If you're training in a shared space or apartment building, the noise from cast iron on cast iron may not be ideal.
Worried about floor damage or noise? Cast iron plates are heavier and louder than rubber coated alternatives, but pairing them with proper rubber gym flooring protects your subfloor and reduces impact noise significantly. Browse our rubber gym flooring range to set up your space correctly from day one.
