IMPORTANT: For cerakote-coated barbells, added care should be used to avoid abrasive metal-to-metal contact. Tight-fitting collars, weight plates, un-lined landmine attachments and j-cups, etc — these can potentially cut into or wear off the cerakote finish. Taking these extra precautions will preserve that beautiful rust-resistant finish for years to come!

Frequently Asked Questions

Its dimensions are: 2,200mm / 86.6 inches long with a 29mm diameter.

It weighs 20kg / 44lbs.

It has a black cerakote coating on both the steel shaft and the sleeves for added resistance to corrosion (rust).

It has a 1,500lb capacity.

A powerlifting barbell differs from an Olympic weightlifting barbell in that it is more rigid to accommodate the heavier weights better. Our power bar is 1mm thicker than the Olympic weightlifting bar and has slightly different markings on the bar. Power bars do not have needle bearing and instead have brass bushing as they don’t need for the sleeves to spin so freely as they do on Olympic bars.

In the box, you’ll find the barbell itself and a coating of oil in order to further minimize any oxidation during shipping and storage.

Covered under our Limited Lifetime Warranty, this guarantees that your bar will not bend under normal use and protects against defects in material, function and workmanship. Read more about our warranty here.

Yes, regular 2-inch collars will fit this bar.

Great bar!!

Really enjoy this bar. The knurling on the bar is perfect aggressive enough for grip without chalk but not so much it tears up your hands. Bar doesn’t have a lot of recoil when lifting heavy. My only issue with the bar is it only took about a week for the powder coating to start wearing off. I wouldn’t of bought the coated bar if I knew it would be so delicate of a coat.

Great Bar

This bar can’t be beat for the price. It has very little give under 500+ lbs, the ribbed sleeves keep the plates in place, the knurling is aggressive enough for a good grip but doesn’t rip your hands apart, and it truly is a sturdy barbell. My only complaints are that it showed up with some surface rust from the packaging and after just a week of usage, the cerakote is chipping on the sleeves from the plates sliding on and off. Other than those two cosmetic complaints, this bar is a great buy.

Awesome and Great Looking Bar

Awesome bar all round! I love the aggressive knurling it feels really stable doing squats and bench presses with these. Now I don’t have to cake my hands and back in chalk! One downside to the black finish is that the wear and scratches on the sleeves do get a little obvious, but that’s a minor issue. Overall very satisfied with my purchase!

You won't find a better cerakote bar for less than $300

I needed cerakote because I live in South Florida and my home gym is outdoors. I've had it for a month and so far it has been great. My only complaint is that they cerakoted the sleeves so the plates scratch off the cerakote over time. Minor issue. Overall, if you need a rust-resistant bar on a budget, this is the one to get.

Jesus, Thank you for the great review. A cerakote bar is a great option if you want to leave your bar outside. This will wear and tear over time but should still hold up well in these conditions. Enjoy the outdoor gainz! -Belll of Steel
