Different use, different types of barbell

  • Powerlifting Barbells:

If you prioritize heavy lifting and strength-focused workouts, Kingsbox powerlifting barbells are ideal. With a more rigid construction and higher weight capacity, they provide stability and support for intense powerlifting movements like squats, deadlifts, and bench presses. They are made from more rigid steel, the Knurl Marks are spaced closer together and the diameter is wider.

  • Weightlifting Barbells:

KingsBox weightlifting barbells are specifically designed for Olympic weightlifting movements, such as the snatch and clean and jerk. They feature more whip and spin to facilitate explosive lifts, allowing for better performance and technique. The steel is more elastic; this way the bar can bend more and have a better “Whip” to it.

  • Hybrid Barbells:

Are suitable for a wide range of strength training exercises. They blend the characteristics of both powerlifting and weightlifting barbells, offering a balanced design that caters to multiple fitness goals. They have dual marks, the weightlifting and powerlifting marks.

  • Beginner Barbells:

For those who are new to weightlifting or strength training, Kingsbox offers beginner barbells with a lighter weight and more forgiving specifications. These barbells provide a comfortable grip and are designed to help users develop proper form and technique.

  • Specialized Barbells:

Kingsbox specialized barbells cater to specific training needs. Whether you’re focused on training for CrossFit, Strongman competitions, or other specialized disciplines, these barbells offer unique features and specifications tailored to your requirements.

Coating Types

We offer a variety of coatings for the barbells, each with its own unique characteristics. Let’s explore some of the most common coating options:

  • Black Zinc: Provides corrosion resistance and durability. Quite good protection but quickly lose its shine.
  • Hard Chrome: Offers a smooth, hardened surface with excellent corrosion resistance.
  • Cerakote: Known for its exceptional durability, scratch resistance, and vibrant color options.
  • Titanium: Lightweight and incredibly durable, suitable for high-performance lifting.
  • Powder Coating: Provides a textured finish for enhanced grip and durability.
  • Cataforesis: A corrosion-resistant coating that ensures long-lasting protection

Knurling and Knurl Marks

Knurling refers to the textured pattern on the barbell’s grip area. Kingsbox offers different types of knurling to suit various preferences:

  • Fine Knurling: Provides a less aggressive grip, suitable for those who prefer a smoother feel during lifts.
  • Medium Knurling: Strikes a balance between grip and comfort, offering moderate aggression for most lifters.
  • Aggressive Knurling: Delivers maximum grip for advanced lifters and those who prefer a more secure hold.
Different types of knurling: no knurling, medium, aggresive and fine knurling

Additionally, some Kingsbox barbells feature central knurling, which provides extra grip during movements that involve resting the barbell on the body, such as squats. The Hybrid Bars come without central knurling. That is because the hybrids are designed for functional and cross-training where high repetition sets of exercises are the norm. Athletes doing high reps could hurt their knees or sheens if there was a central knurling.

Tensile Strength

Tensile strength refers to the maximum amount of weight a barbell can withstand before it permanently bends or breaks. The tensile strength test is a process that tests how much pressure it takes for a barbell to deform permanently. It is measured in Pounds per Square Inch (PSI).

Kingsbox barbells come in different tensile strength ratings, allowing you to choose the appropriate level of durability for your training intensity.

Good quality barbells start at 165.000 PSI. When the PSI goes above 190.000 we start talking about supreme-quality barbells. The rule is: the higher the PSI, the higher the price.



195.000 PSI: THE C BAR – WOMEN’S OL BARBELL (298,9€)

205.000 PSI: GOLD BAR (336,72€)

215.000 PSI: ROYAL WL BAR II. (771,65€)
