2. Barbell Industry Region
The main places in China where barbells are made are Hebei, Nantong, Qingdao, and Tianjin. In Hebei, most barbells are sold to the Zhejiang Yiwu Wholesale Market. The quality of barbells from this region is not very high. The raw materials are often not heat-treated and are nickel-plated, making these barbells rough, cheap, and low quality.
A few companies, like Zhang Kong and DHS Sports, can even make competition-grade barbells. Each year, about 200,000-300,000 high-end barbells are sold worldwide. Around 80,000 of these are bought from China. Seems like that this country contribute a lot to the increasing demand of barbell that has a CAGR of 12.2%, as per VMR.

4. Barbell Physical Structure
The physical structure of a barbell plays a crucial role in how it performs during lifts. Understanding the different components of a barbell helps gym owners select the right equipment for their gym.
Sleeve
The sleeve is where the weight plates are loaded. The sleeve’s length determines how much weight can be added, while its design impacts rotation. Between the bar and sleeve, bushings or bearings are used to allow smooth rotation during lifts. Here are the key components of sleeve:
Bushing
There are different types of bushings used in barbells, each offering unique benefits. They help reduce friction between the bar and sleeve, allowing the bar to rotate smoothly. Here are the most common types:
- Typical Bushing: Most barbells use typical bushings, which are made from brass or bronze. These bushings reduce friction and last a long time. Brass bushings are self-lubricating, which makes them low maintenance and suitable for regular gym use.
- Olite Bushing: Made from porous bronze and contain oil, which lubricates the bar as it rotates. They offer better durability and performance compared to regular bushings. Olite bushings are often used in higher-quality barbells because of their ability to handle heavy loads with less maintenance.
- Composite Bushing: It is made from durable plastic materials. They are stronger and last longer than metal bushings. When tested, composite bushings provide a more even and consistent rotation, making them a reliable option for long-term use in high-performance barbells.
Bearing
Bearings are used in barbells to provide smoother, quieter, and more stable rotation. As a matter of fact, they help reduce friction between the bar and the sleeve, allowing for better control during heavy lifts. Most barbells have 8 to 10 bearings, but the quality and type of lubricant matter more than the number of bearings. Professional lifters often prefer barbells with bearings because they perform better under heavy loads. Here are 3 types of bearings:
- Ball Bearings: These are the most basic type of bearing but can be slightly noisier than others.
- Thrust Bearings: These offer better rotation and are quieter than ball bearings.
- Needle Bearings: These are the highest quality and offer the smoothest and quietest rotation, often found in high-end barbells.
Sleeve Design
The sleeve design refers to how the sleeve is attached to the bar. There are 3 methods: snap ring, end cap, and hex bolt. Snap rings and end caps are safe and reliable, while hex bolts are less secure and often used in lower-quality bars.
Shaft
The shaft is the main part of the barbell that lifters grip during exercises. It’s made from strong materials like steel and is designed to withstand heavy loads without bending. The knurling on the shaft provides grip, while its flexibility (or whip) varies depending on the type of bar. Below are the key components of shaft:
Raw Barbell Materials
Most barbells are made from steel, with the specific type of steel affecting the bar’s strength and durability. High-end barbells are typically made from stainless steel. Common raw materials used for barbells include:
- A3 steel
- 45 steel
- Alloy steel
- Low-end spring steel
- High-end spring steel
Knurling
Knurling refers to the textured area on the barbell shaft, which is cut by a machine to improve grip. According to the International Weightlifting Federation (IWF) and the International Powerlifting Federation (IPF), men’s 20kg bars must have central knurling. However, for women’s 15kg barbells, the IWF specifies that there should be no central knurling. Here are other key aspects of knurling:
- Knurling Position: On a standard Olympic bar, the shaft measures 131 cm in length. Besides the two 15 cm smooth sections at each end and two 5 mm-wide rings or marks, the remaining areas of the shaft should be knurled to provide grip.
- Knurling Depth: Knurling depth typically ranges from 0.35 mm to 0.5 mm, though the design and feel can vary. High-quality barbells strike a balance between too much (positive) and too little (negative) knurling. Similar to sandpaper, different knurling provides different levels of grip. Insufficient knurling can make it hard to hold the bar, causing grip failure, while overly aggressive knurling may scratch or cut the palms.
- Knurling Border: Knurling borders have become a recent trend in barbell manufacturing. These raised lines are visually appealing and often promoted as a sign of quality. However, they can weaken the barbell’s steel. The cutting involved in creating these borders introduces stress points, making steel more vulnerable. This issue becomes more significant as the tensile strength of the bar increases, potentially compromising the barbell’s durability.
- Knurling Types:
- Type 1: Sharp Diamond Projections: This knurling type features small, sharp projections that dig into the skin of the palm for a tighter grip. While this helps secure the bar in the palm, it can also cause skin tears as the bar turns in the hand. Additionally, when deadlifting, the bar’s closer contact with the body increases the chance of shin abrasions.
- Type 2: Flat Diamond Design: The flat diamond design is less aggressive and reduces the risk of tearing the skin or scraping the shins. However, with less sharpness, there is also less friction, which can result in a less secure grip compared to sharper knurling.
- Type 3: Concave Diamond Design: This design features concave diamonds that press the skin into the knurling, increasing friction for a closer grip. The lack of sharp edges reduces the chance of skin tears and shin scrapes. This design spreads the stress more evenly, making it more comfortable and popular among gym users.
Finish
When discussing the finish of a barbell, we’re referring to the treatment of both the shaft and sleeve. At YR Fitness, we applyhard chrome to all our barbells, meeting competition standards. You can expect the finish to last at least 12 months. Always ask about the barbell’s finish before purchasing to ensure durability. Here are the 10 most common finish treatments:
- Bare Steel: Bare steel looks and feels great initially, but it rusts quickly without proper care. Regular oiling, wiping off sweat, and storing in a temperature-controlled environment can help prevent rust. Over time, a bare steel bar will develop a natural patina and offer a solid grip.
- Black Oxidation: This finish gives the bar a “bare steel” feel with some rust protection, but it’s limited. It requires the same maintenance as bare steel, such as oiling and wiping down after use, to prevent rust.
- Black Manganate Phosphating: This finish gives the bar a matte black appearance and better rust protection than black oxidation. It’s a chemical process that blackens the steel. The finish may scrape but won’t peel, though rust can occur if not maintained properly.
- Black Zinc: Black zinc adds resistance to the steel and prevents water from causing rust. However, it wears out quickly and becomes smooth when hands are sweaty. Over time, the finish may turn green if not maintained regularly.
- Hard Chrome: Hard chrome, available in polished or satin finishes, is the most durable and expensive option. It’s commonly used on competition barbells and can last over 20 years. However, it may feel slippery, and high-quality knurling is needed to offset this.
- Decorative Chrome: This is a cheaper imitation chrome used on low-quality barbells. It tends to break or peel easily and rusts quickly. If the bar bends, the finish will crack.
- Nickel Plating: Nickel plating provides a classic look but is prone to peeling more easily than hard chrome. It’s often found on lower-quality bars to give the appearance of a premium finish.
- Bright Zinc: Bright zinc has a shiny, chrome-like look but offers a more cost-effective alternative to hard chrome. It provides good rust protection in humid environments but will turn gray over time as it sacrifices itself to protect the steel beneath.
- Cerakote: Cerakote is a durable colored ceramic finish, often used on guns. It’s strong and offers good rust protection, but it’s more expensive than most other finishes.
- E-coat: E-coat is an electronic coating offering excellent rust and oxidation resistance. It’s cheaper than black zinc and better for the environment, complying with safety standards like Rohs, OSHA, and EPA. It resists corrosion from water, sunlight, and chemicals.
5. Barbell Physical Properties
Steel quality plays a key role in how well a barbell performs. The 2 major factors to consider when evaluating a barbell’s steel are tensile strength and yield strength. To guide you, here are the main properties to keep in mind:
Yield Strength / Max Load Capacity
Yield strength is the amount of weight required to permanently bend a barbell. This strength is tested by loading weights onto the bar, though it’s not the most accurate method. The maximum load capacity of a barbell also depends on the length of the sleeve and the configuration of the weight plates. In commercial gyms, it’s best to use only a quarter of the bar’s maximum load capacity.
Tensile Strength
Tensile strength refers to the amount of pressure a barbell can withstand before breaking. It is measured in pounds per square inch (PSI). Higher PSI values mean the barbell is stronger and more durable. All of the barbells made by YR Fitness have PSI’s that are at least 170,000. Some of them are even in excess of 200,000 PSI. Here is an overview of barbell usability according to tensile strength:
- 150,000: It is suitable for beginners and general gym users.
- 150,000-180,000: A good fit for most professional athletes.
- 180,000+: A well-constructed barbell that lasts for a long time.
Whip
Whip is the barbell’s ability to bend under load, providing flexibility during lifts. Olympic bars require some whip to help with movements like the snatch and clean and jerk, while powerlifting bars are more rigid. The whip effect of a barbell is influenced by 4 main factors:
- Load on the barbell: The more weight you put on the bar, the more it will bend or whip.
- Materials: Different materials create different amounts of whip. Molybdenum alloy bends more, while untreated steel and carbon steel bend less.
- Diameter: Thicker bars bend less. For instance, a 29 mm bar will whip less than a 28 mm bar if they are made from the same material.
- Processing Method: How the bar is made, like if it’s heat-treated or cold-rolled, can also affect how much it bends.
6. Barbell Manufacturing Process
The process of making barbells involves several key steps to create strong and durable equipment. I believe each stage impacts the overall quality and performance of the barbell. Here are the main stages of the barbell manufacturing process:
Step#1 Raw Material Treatment
The process begins with selecting high-quality steel, which undergoes treatment to enhance its strength and flexibility. This treatment prepares the raw material for the other steps, making it suitable for use in creating durable barbells.
Step#2 Tensile Strength Test (PSI)
Next, the bar is tested to measure its tensile strength, which determines how much pressure the bar can handle before breaking. The higher the PSI (pounds per square inch), the stronger and more durable the barbell will be.
Step#3 Straightening
After testing, the bar is straightened to make sure it has no bends or warping. This step is crucial for producing a barbell that is balanced and safe for lifting. Proper straightening also helps avoid issues during the knurling and polishing stages.
Step#4 Pipe Flaw Detection
Now that the bar is straightened, it goes through pipe flaw detection to check for any internal or external defects. This step is important for making sure that the bar is free of flaws that could weaken its structure or affect its performance during heavy lifts.
Step#5 Knurling
Once the bar is verified for strength and quality, the knurling process begins. Knurling adds a textured grip to the barbell shaft, improving the lifter’s grip during exercises. The knurling pattern is tailored to the bar’s specific use, providing an effective grip without compromising comfort.
Step#6 Cleaning and Assembly
After knurling, the barbell is cleaned and assembled. The sleeves are attached to the shaft using either snap rings or end caps for a secure connection. This assembly step is critical to the barbell’s long-term durability and stability during heavy lifts.
Step#7 Packaging
Finally, the finished barbells are carefully packaged to protect them during shipping. Proper packaging prevents damage to the barbell’s surface and structure, ensuring they arrive at the gym in top condition.
7. Tips For Choosing the Best Barbell For Your Gym
When choosing the right barbells for your gym, it’s important to consider factors that impact performance, durability, and safety. Here are some key tips to help you select the best barbells for your gym:
#1 28mm-29mm Diameter
Look for a barbell with a 28mm-29mm diameter. This size offers a comfortable grip and is ideal for most exercises. It provides better control for both beginners and experienced lifters.
#2 Hard Chrome Coating
Confirm that the barbell has a hard chrome coating. This coating protects the bar from rust and wear, making it last longer. For example, if your gym is in a humid environment, a bar with hard chrome will help prevent corrosion over time.
#3 At least 190,000 PSI
Look for a barbell with at least 190,000 PSI, which measures its strength. This is important for heavy lifting to prevent bending. If your gym members regularly lift heavy weights, a higher PSI ensures the bar will withstand the load.
#4 End Cap Systems
Look for a reliable end cap system that secures the sleeves during use. Wanna know why? For example, in high-traffic gyms, a solid end cap system keeps the bar functioning properly even with frequent, heavy use.
Conclusion
In conclusion, the best barbell for your gym will depend on the specific features that matter most to your members and the types of exercises they’ll be doing. By considering the factors mentioned above, you can confidently select the barbell that fits your gym’s needs.
