Frequently Asked Questions

What is the difference between Olympic, powerlifting, and standard barbells?

  • Olympic barbells (20kg men’s, 15kg women’s) have rotating sleeves with bearings or bushings for dynamic movements like snatches and cleans.
  • Powerlifting bars are stiffer, feature aggressive knurling, and have minimal sleeve rotation for controlled lifts like squats, bench presses, and deadlifts.
  • Standard barbells (often non-Olympic) have different sleeve sizes and are less common in professional gyms. 

How do I maintain and clean my barbell?

Regularly brush the knurling with a stainless steel brush, wipe down the shaft with a light coat of oil, and store your bar in a dry environment to prevent corrosion.

For more information on Barbell Maintenance please read more here>>>

What is the difference between a 20kg and a 15kg barbell?

The 20kg barbell is thicker (28-29mm shaft) and designed for heavier loads, while the 15kg bar has a thinner shaft (25mm) for better grip, particularly for Olympic weightlifting.

Are your barbells and weight plates competition-approved?

Our Competition Bumper Plates and Power Bars meet the specifications required for competitive weightlifting and powerlifting. If you're training for competition, we recommend checking out our calibrated plates and bars.

Do your bars and plates come with a warranty?

Yes. All BLK BOX branded equipment is covered by a limited 12-month warranty.
