Description

Precision-Machined Olympic Plates for Reliable Strength Training

The Troy (PO) Black Machined Olympic Plates are manufactured from ASTM Grade 20 cast iron and precision machined across the face, outer edge, and center hole to provide improved balance, smoother loading, and a dependable fit on standard 2-inch Olympic bar sleeves. Compared to basic cast iron plates, the machined design offers greater consistency while maintaining the traditional feel preferred by many strength athletes. The wide flange profile provides additional gripping surface for easier loading, unloading, carrying, and storing between workouts, making them an excellent choice for expanding an existing free weight area or outfitting a new strength training facility.

Purchasing & Configuration Options:

Individual Plates: Available as single (1) units to target specific size additions or structural replacements.
Preconfigured Plate Packs: Multiple matching plate bundles (4, 6, 8, or 10 packs) to load specific sizes efficiently.
Stock Plate Sets: Pre-matched Olympic packages ranging from 245 lbs up to 2760 lbs to completely supply multi-user lifting lines.
Custom Plate Sets: Tailor a personalized combination by selecting custom size quantities via the "Add to Quote" request tier.

Key Product Features

ASTM Grade 20 Iron: Heavy-duty, time-tested raw iron casting delivers structural longevity under demanding daily loads.
Precision Machined Surfaces: Fully calibrated milling across the face, perimeter edge, and core opening optimizes concentric balance.
Wide Flange Profile: Deep outer rim design creates a larger tactile gripping surface for easier, safer manual handling.
Baked-On Black Enamel: Hardened defensive shell finish strongly resists premature chipping, moisture corrosion, and scuffs.
Flawless Sleeve Loading: Precision-bored 50.4 mm center holes slide cleanly over Olympic bars to prevent rattle or loose shifts.
Raised Face Sizing: High-contrast weight designations and clean Troy branding ensure rapid identification along the platform line.

Frequently Asked Questions

Q: What specific functional benefit does a machined plate design provide over basic cast iron?
A: Standard castings often carry irregular sandy seams and slightly offset centers. Fully machining the face, outer edge, and center collar guarantees an exceptionally precise bar fit, vastly smoother loading transit, and far more consistent weight balance.

Q: Are these Troy PO Black Machined Plates priced and sold as matched pairs?
A: Individual size options chosen directly from the selector menu are priced and sold singly as a single (1) plate. Preconfigured stock sets and bulk plate packs bundle the exact weight assortments detailed in our data layout tables.

Q: What advantage does the integrated wide flange profile offer the lifter?
A: The wide flange layout increases the available surface depth around the outer rim of the plate. This provides a much deeper edge lip, making lifting, gripping, and manually sliding heavy 45 lb or 100 lb increments off trees and bars substantially more secure.

Q: Do the high-capacity 100 lb plates share the exact outer diameter of the standard 45 lb plates?
A: Yes. Both the 45 lb and 100 lb variants share an identical 17.72-inch outer diameter configuration. This maintains an aligned loading profile on plate-loaded machinery and bar sleeves, though the 100 lb model features a thicker width.

Q: Will the black enamel finish flake or wear off quickly under continuous heavy usage?
A: No. The specialized enamel coating is professionally baked onto the ASTM Grade 20 iron core. This treatment hardens the exterior skin to strongly defend against premature surface chipping, rust corrosion, and daily friction wear.

Q: Are these machined iron plates appropriate for high-traffic institutional weight rooms?
A: Yes. Possessing a heavy-duty commercial-grade architecture, they are fully rated to perform inside high school lifting blocks, collegiate gyms, personal training studios, military bases, and serious home strength setups alike.

Great purchase experience buying Troy PO cast iron weight set

Posted by Aaron S. on Feb 11, 2021

I found this website by chance and purchased a 345 lb Troy fitness PO weight plate set. Estimated time for delivery was 4-6 weeks. Weights were delivered right at 3 weeks. Great communication through email to let me know that weights had shipped. Awesome experience and will go thru them again.
