Plate specifications FAQ
What barbell sleeve diameter do these fit? +
These fit standard 28 mm bars and 25 mm bars. They do not fit 50 mm Olympic sleeves.
Are the weight markings raised or stamped? +
The markings are cast directly into the iron mold so they will never rub off.
Can these plates crack if dropped on mats? +
Grey cast iron is structurally rigid for routine lifting, but uncontrolled drops onto concrete are not recommended.
Are they oily when unpacked? +
No. The baked powder coat creates a clean, dry exterior without oily factory residues.
