E-Coat Iron Weight Plates — machined and coated to perfection.

Thought our original Machined Plates couldn’t get any better? Think again.

Our e-coat weight plates have the same 1-3% guaranteed accuracy and 50.5mm center hole as our original Machined Iron Weight Plates, but now with a glossy black e-coat.

Benefits of the E-Coat Weight Plates

    If you know that a bare steel powerlifting bar would rust in your humid home gym, then do we have you covered. The thin electro-coating (e-coat) on our e-coat weight plates gives excellent rust resistance. So you can sweat  — or cry — on them between sets without worry.
    These machined plates are a guaranteed tolerance of +/- 1% for 25-45lbs, and +/- 3% for 2.5-10lbs. However, in our strict quality control and inspection, most plates are under that tolerance, and many fall within 10 grams of the claimed weight.  If you’re looking for excellent quality but a less precise plate, be sure to check out our E-Coat Mighty Grip Iron Plates.
    Inferior plates have inconsistent center hole sizes, allowing them to rattle and shift around while you’re lifting. Not only is readjusting them after each set annoying, but they can also damage your barbell sleeves over time. Our e-coat weight plates are precision-drilled with a guaranteed hole diameter of 50.5mm +.4mm tolerance, giving your plates that perfect fit.
    So, you’re not a huge fan of the gray hammertone color on our original machined plates? No biggie. The all-black color on these e-coat iron weight plates will upgrade your space by becoming the sleek centerpiece of your home gym.

Features and Benefits

Natural Texture

Originally made for the automotive industry, e-coating has become increasingly popular due to its great durability and excellent rust resistance. Although it’s applied in a thin layer, the smooth texture still allows the natural grit of the iron underneath to be felt.

Easy to Clean

Thought that glossy e-coat was just pretty to look at? Oh, silly you. Since the coating binds directly to the iron in a smooth layer, it has fewer grooves for chalk, sweat and bacteria to hide. One quick wipe and your plates are squeaky clean.

20% Thinner Width

Our 45-pound plates are only 1.2 inches (31mm) thick— about 20% thinner than the industry standard. Combined with our powerlifting bar, you’ll be able to add over 700 pounds to the bar in plates and still have plenty of room to spare on the sleeve.

40 Years of Experience

Our machined iron plates are cast in a specialty casting factory with over 40 years of experience, for reliable quality and workmanship that you can trust.
