Rank #1 in Best Olympic Weight Plates 2026: 10 Sets Ranked, and Why the KG Label Misleads
PhysKcal 50mm Tri-Grip Olympic Weight Plates, 1.25–25 kg
Price and rating as shown on Amazon when we collected them. Both change.
The PhysKcal 50 mm Olympic Weight Plates are tri-grip cast iron discs with a rubber coating, sold as pairs and made in sizes running from 1.25 kg to 25 kg across the line. This is the entry that sits at number one in our guide to weight plates, and it is the one listing in that guide where the advertised figure and the data table underneath it actually agree.
The number to watch is still the one in the title. "1.25-25 kg" is the span of the whole PhysKcal range, not the contents of any single box. What you get for £33.99 is set by the variant field, which reads "e) 5KG x 2", and by Number of Items, which is 2 — so a pair of 5 kg plates, 10 kg of iron in total. That is exactly what the Item Weight field says: 10 kg. Add it up yourself and it lands. The same cannot be said of the other plates in this guide, where the headline kilogram figure and the item weight are two different numbers. Everything on this page is taken from the PhysKcal Amazon listing, not from any test carried out by us.

Questions people ask
What do you actually get for £33.99?
The variant field on the PhysKcal listing reads "e) 5KG x 2" and Number of Items is 2, which matches the 10 kg Item Weight: a pair of 5 kg plates.
Does the "1.25-25 kg" in the title mean one box holds all of that?

Solid cast iron, with a rubber finish the listing gives as 5 mm dense rubber, which it says reduces noise and floor damage.
