Ghost Strong Calibrated KG Steel Plates

Name: Ghost Strong Calibrated KG Steel Plates
Brand: Ghost Strong
Rating: 4.33 (6 reviews)

Ghost Strong’s Calibrated KG Steel Plates are cast-iron competition plates machined to a strict +/-10 gram weight tolerance, approved for competition by the United States Powerlifting Association at the time of manufacture. Each plate carries a rear calibration plug for extra precision and a 50.40mm collar opening that fits any standard Olympic barbell, with a 700kg max loading capacity per plate. The full KG lineup spans ten increments – 0.25, 0.5, 1.25, 2.5, 5, 10, 15, 20, 25, and 50kg – sold in pairs, plus bundled 159kg and 459kg sets, and the plates are color-coded by weight for quick identification on the platform. Rogue closed the line out as limited-quantity stock after acquiring the Ghost Strong brand, and it is now fully discontinued with no current retail listing anywhere.

What is a Weight Plate?

What weight plates are

Weight plates load your barbell — but “plate” covers two very different tools. Bumper plates are rubber discs around a steel hub, all the same ~450mm diameter, built to be dropped from overhead without damaging your floor or bar; they’re the default for Olympic lifting and CrossFit. Iron/steel plates are denser and thinner per pound, cheaper, and quieter to load, but most aren’t made to be dropped — better for slow, controlled powerlifting-style work.

What actually matters

Bumper vs. iron. Buy bumpers if the bar might hit the floor; iron (or rubber-coated iron) for controlled lifts and compact loading.
Weight tolerance. How far a plate strays from its stated weight (±1% is tight, ±3% loose). It barely matters for general training but adds up if you chase a specific total — which is why serious lifters add small change / fractional plates.
Collar fit & bounce. The center hole should fit your bar’s sleeve snugly; rubber durometer (around 88 Shore A) controls how “dead” a dropped plate lands.
Coating & set composition. Virgin rubber holds up and smells less than recycled crumb rubber; plan a starting set (usually a pair each of 45/25/10/5 lb plus change plates) around the lifts you actually do.

Who it’s for

Every barbell gym needs plates. Most home lifters should start with a bumper set, then add iron, change, or specialty plates as a second purchase once they know what their training is missing.

Ghost Strong’s KG Calibrated Steel Plates are cast-iron, machine-calibrated plates (accurate to +/-10g) that Rogue closed out and discontinued after acquiring the Ghost Strong brand — they’re no longer sold anywhere at a current retail price. Owners on GymRadar rate performance and build quality well (4.67/5 each across 6 reviews), but value trails at 3.67/5: several independent reviewers describe them as essentially the same casting as Rogue’s own Calibrated KG Steel Plates 2.0 with a Ghost logo swapped on at a higher price. The recurring complaint is paint durability (“terrible” longevity per one reviewer), while accuracy and looks draw consistent praise.

+Performance: GymRadar owners rate accuracy/performance 4.67/5 across 6 independent reviews
+Build quality: cast iron machined to +/-10g tolerance with calibration plugs, rated 4.67/5 on GymRadar
+Functionality: 50.40mm collar opening fits any standard Olympic barbell, 700KG max loading capacity per plate
+Versatility: full 10-weight KG range (0.25kg-50kg) plus 159kg and 459kg set options

−Value: GymRadar's lowest-rated dimension (3.67/5) — multiple reviewers call it the same Rogue-made casting at a higher price for the Ghost logo
−Durability: one reviewer flags paint finish as "terrible" with no longevity
−Availability: discontinued and closed out after Rogue's acquisition of Ghost Strong — no current retail listing at any price
−Value: Rogue's own equivalent, Calibrated KG Steel Plates 2.0, is the actively-sold alternative at a lower price per multiple reviewers
