Cast Iron Machined Weight Plate

Name: Cast Iron Machined Weight Plate
Brand: Weight It Out
Rating: 4.47 (17 reviews)

Weight It Out is a small American manufacturer (Midwest foundry) whose cast iron plates are built around one pitch: they’re the thinnest cast iron plates on the market, at 3/4” for a 45 lb plate versus roughly 1.5”-2” for a typical cast plate. That density lets a lifter load more weight onto a barbell with short sleeves and store far more plates in the same rack space, and each plate is machined to within +/-1% of its stated weight and finished with cast-in dual handles for carrying and loading.

Independent coverage is consistently positive. ShreddedDad rated the line 4.75/5, verifying a 45 lb plate at 44.6 lb against nominal, and both Garage Gym Reviews and The Movement Review call it a strong pick for powerlifters and space-constrained home gyms. A detailed owner YouTube review (channel: Kurtis) measured several plates directly – diameter, thickness, and bore all landed within spec – and confirmed the newer cast iron line rounded over a sharp edge that was a common complaint on earlier runs. r/homegym commenters repeatedly recommend the brand by name for anyone wanting thin, space-saving plates, with the recurring caveat that they’re a premium-priced product, not a budget option. The main functional trade-off flagged across sources: the thin profile has less barbell “whip” than a standard-depth plate and needs a snug collar to stop plates from shifting during heavy deadlifts.

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.

Weight It Out’s whole pitch is thinness – a 3/4” 45 lb plate versus the 1.5”-2” of a typical cast plate – and Functionality is the standout dimension: independent owner measurements (ShreddedDad, a detailed YouTube teardown) confirm the +/-1% weight tolerance and tight machining hold up, letting lifters load more plate onto shorter barbell sleeves without running out of room. Value is the weakest dimension – reviewers and r/homegym commenters alike flag it as a “premium price” product rather than a budget one, and GymRadar’s own on-site rating (4.47/5, n=17) sits a notch below the glowing independent write-ups, suggesting some buyers weigh the cost more heavily than reviewers do. The thin profile trades off some barbell “whip” versus a standard-depth plate, and needs a snug collar to keep plates from shifting on heavy deadlifts, but no source raises durability or build-quality concerns with the cast iron or coating itself.

+Functionality: independently measured within its claimed +/-1% weight tolerance and Olympic-spec dimensions across multiple plates (ShreddedDad; owner YouTube teardown by Kurtis)
+Functionality: the thin 3/4" 45 lb profile lets more weight load onto short-sleeve barbells and saves storage space versus standard-depth cast iron (ShreddedDad; Garage Gym Reviews; owner YouTube reviews)
+Build quality: newer production rounds over a sharp plate edge that was a common complaint on earlier runs, confirmed by a side-by-side owner comparison (YouTube: Kurtis)
+Versatility: nine finish/color options plus a lifetime warranty, with dual cast-in handles for one- or two-hand loading (manufacturer product page; The Movement Review)
+Durability: no source reports coating failure, cracking, or density/balance issues -- one reviewer specifically noted even weight distribution versus a prior cast plate brand (YouTube: Kurtis)

−Value: repeatedly flagged as a premium-priced plate rather than a budget option, both in editorial reviews (Garage Gym Reviews) and recurring r/homegym commentary
−Value: GymRadar's on-site rating (4.47/5, n=17) reads a notch below the independent editorial and video verdicts, suggesting a wider range of buyer sentiment on cost-to-value
−Functionality: the thin plate profile produces less barbell "whip" than a standard-depth plate, noticeable to some lifters on deadlift-style bars (YouTube: Kurtis)
−Functionality: requires a snug-fitting collar to prevent plates from shifting or rocking during heavy pulls, due to the thinner sleeve fit (Garage Gym Reviews; The Movement Review)
