1. What is a commercial curl bar?

A commercial curl bar is a specialty bar having a jagged shape. It is a short and lightweight barbell. It is used to avoid the discomfort that is present while lifting a straight barbell. It allows the user to hold the bar in a more natural position.

2. What are the different types of commercial curl bars depending on usage?

There are three different types of commercial curl bars based on the difference in their functionalities. 

Rackable Commercial Curl Bar

  1. Can be racked on a power rack
  2. Plates can be loaded on it. 
  3. Longer than a non-rackable EZ curl bar.

3. What are the different types of commercial curl bars depending on structure?

A commercial curl bar can either be free weight or fixed weight. 

Free Weight Commercial Curl Bar

Free weight commercial curl bar is a curl bar with plate loading sleeves. Olympic plates can be loaded on them to customize the weight.

Fixed Weight Commercial Curl Bar

A fixed weight commercial curl bar consists of a curl bar with permanently attached plates/ weights. The weight cannot be customized on them. They are available in a variety of weight.

4. Is a free-weight commercial curl bar better than a fixed-weight commercial curl bar?

Yes, a free-weight commercial curl bar is better than a fixed-weight commercial curl bar. This is because users can customize the weight on them according to their preferences. Moreover, one bar will be enough for all types of trainers. 

On the other hand, a fixed weight commercial curl bar cannot be used by all types of trainers. And you will have to buy a complete set to provide sufficient weight options. Besides, the highest weight might still not be enough for high-level trainers. And the lowest weight might be too heavy for beginners. 

Therefore, for a commercial gym, a free-weight commercial curl bar is a better option. On the other hand, for a distribution center, you should buy both varieties. 

5. What type of finish does a commercial curl bar can have?

The following are the different types of finishes that a commercial curl bar may have:

Bare Steel

Pros:

  1. Provide an efficient grip with a natural feel. 

Cons:

  1. Can get rusted easily. 
  2. Requires careful maintenance. 

Black Oxide

Pros:

  1. More rust-resistant as compared to bare steel. 
  2. Do not require a lot of maintenance. 

Zinc

Pros:

  1. Provides protection from rust more than black oxide. 

Cons:

  1. Quickly lose its shine. 
  2. Requires more maintenance than black oxide. 

Chrome

Pros:

  1. Provide maximum resistance from rust among all types of finishes. 
  2. Have excellent knurling.

Cons:

  1. Expensive as compared to barbells with other types of finishes. 
  2. Might be slippery as compared to bare steel. 

Stainless Steel

Pros:

  1. Gives an excellent feel. 
  2. Excellent rust protection. 

Cons:

  1. Expensive. 

Cerakote

Pros:

  1. Colored ceramic. 
  2. Rust resistant
  3. Durable 

Cons:

  1. Expensive. 

Electro-coating

Electric attraction is used to coat paint. 

Pros:

  1. Durable
  2. Rust resistant. 
  3. Which materials are used to make a commercial curl bar?

A commercial curl bar is manufactured using steel. 

For a quality bar, the steel should follow Q235 standards. The finish on the steel differs according to the area of the bar. The shaft is generally electrically coated, while the plate loading sleeve is usually zinc coated. 

Yanre Fitness uses a hard chrome finish for its commercial curl bars. 

6. What is the importance of knurling in a commercial curl bar?

The two opposite sets of diagonal grooves on barbell form knurling. These edge shapes increase the efficiency of the grip. Their intensity is determined by their aggressiveness. 

A more aggressive knurling results in a stronger grip. The following are the three different types of knurling that a commercial curl bar can have:

  1. Mountain Knurling. 
  2. Volcano Knurling.
  3. Hill Knurling. 

Hill Knurling is the worst of all types because it is difficult to hold. Whereas Volcano knurling is the best of all types.

7. What parts of a commercial curl bar have knurling?

The curved portion of the bar, adjacent to the plate loading sleeve have knurling. A commercial curl bar does not have center knurling.

8. Is the commercial curl bar rackable?

Some commercial curl bars are rackable while others are not. 

However, we recommend buying a rackable bar because it makes plate loading and storage easier. Moreover, a bar that can be racked on a power rack can also be used for pull-up exercises. Therefore, this feature increases its utility. 

The distance between the plate loading sleeve gives an estimate about whether the bar is rackable or not. Before ordering a commercial curl bar, contact the manufacturer for confirmation about this feature. 

On the other hand, a non-rackable commercial curl bar is easier to use because of its small size. Therefore, some users might prefer it too. So, if you have a budget, you should buy both varieties. 

9. What are the average dimensions of a commercial curl bar?

The dimensions of a commercial curl bar differ according to whether it is rackable or not. This is because rackable commercial curl bars are longer than non-rackable ones. 

The following are the average dimensions of both types of bars:

Rackable Commercial Curl Bar

Total length: 74.75 inches

Shaft Diameter: 1 inch

Sleeves Diameter: 2 inches 

Distance between sleeves: 52 inches

Loadable Sleeve Length: 10.5 inches

Non-rackable Commercial Curl Bar

Total length: 54.5 inches 

Shaft Diameter: 1 inch

Sleeves Diameter: 2 inches

Distance between sleeves: 31.5 inches

Loadable Sleeve Length: 10.5 inches

Pull-up Commercial Curl Bar

Total length: 43 inches

Loadable Sleeve Length: Absent

Shaft diameter: 1 inch

Please note that these are general measurements. The EZ curl bar that Yanre Fitness provides has a length of 47 inches and the length of loadable sleeve length is 6.6 inches. 

10. How much does a commercial curl bar weigh?

The average weight of a commercial curl bar differs according to its type. The following is the list of average weights of commercial curl bar:

Rackable commercial curl bar: 35 pounds

Non-rackable commercial curl bar: 30 pounds 

Pull-up commercial curl bar: 17 pounds

Besides, the weight of the commercial EZ curl bar also differs according to the quality of materials used to make the bar as well as its finish. Therefore, it is best to contact the manufacturer to know the exact weight of the bar to estimate shipping costs. 

The commercial curl bar provided by Yanre Fitness weighs 22 pounds. 

11. What is the tensile strength of a commercial curl bar?

The average tensile strength of the commercial curl bar is 45,000 PSI. 

This value refers to the breaking point of the bar. It can be used to estimate how much weight the bar can hold. It depends on the quality of the bar. The higher it will be, the better will be the quality of the bar.

12. What is used for rotation in a commercial curl bar?

Bushings or bearings are generally used for rotation in a commercial curl bar. They are made up of bronze. They provide a smooth feel between the shaft and the plate loading sleeve. 

The commercial curl bar provided by Yanre Fitness consisted of 4 needle bearings.

13. Which type of weight plates can be used with a commercial curl bar?

Olympic weight plates are used with a commercial curl bar. 

This is because the diameter of the plate loading sleeve of the bar and the diameter of Olympic weight plates is 2 inches. 

Carefully check the diameter of the plate loading sleeve of the commercial curl bar. This is because, if the diameter of the sleeve is smaller than 2 inches, the plates will rattle during usage. Whereas, if the diameter is larger than 2 inches, the plates would not be loaded. 

The following are the few types of Olympic weight plates that can be used with commercial curl bar:

  1. Bumper plates
  2. Technique plates
  3. Competition weight plates
  4. Tri-grip weight plates.

14. What is the sleeve design of a commercial curl bar?

Snap ring sleeve design is generally used for commercial curl bar. 

The following are the two other types of sleeve design that a commercial curl bar may have:

  • Endcap
  • Hex Bolt

Endcap and Snap ring designs are both equally acceptable for a commercial curl bar. However, the Hex bolt design should be avoided. 

15. What is the maximum weight loading capacity of a commercial curl bar?

The maximum weight loading capacity of a commercial curl bar is 300 pounds. 

This value refers to the total weight of plates that can be loaded on the commercial curl bar. It depends on the type, quality, and size of the bar. 

Make sure that users do not load more weight on the commercial curl bar than its maximum weight loading capacity. This is because the bar may break and cause an injury. 

16. Do I get weight plates with a commercial curl bar?

No, weight plates are not sold with a commercial curl bar. 

You need to buy them separately. However, make sure that the weight plates you buy are compatible with the commercial curl bar. The diameter of the plate loading sleeve of the bar should be equal to the diameter of the central hole of the weight plate.
