2. Weight Plate Types
There are several types of weight plates available, each offering unique benefits. Knowing the different options can help you choose the best for your gym’s needs. Here’s a quick look at the main types to get you started:
By Material: Steel vs Cast Iron
Weight plates come in 2 common materials: steel and cast iron. Both are widely used in gyms, but they have key differences that impact cost, durability, and performance.
Cast iron plates have been the standard for many years. They are less durable but more affordable than steel plates. Both types are used similarly, but there are 2 main versions:
- Calibrated Weight Plates: Whether steel or cast iron these plates are designed for precise weight accuracy, ideal for serious lifters and competitions. They are thinner than regular plates, allowing more weight to be loaded on the bar. Though more expensive, they provide better precision and durability.
- Regular Metal Plates: Regular cast iron or steel plates are affordable and effective for general use. While they are noisier and less accurate than calibrated plates, they are a cost-effective solution for most gyms.
By Finish & Coating
When choosing weight plates, the finish and coating play a significant role in durability, noise, and protection for your equipment and floors. Most commercial gyms use rubber or urethane-coated plates because they are budget-friendly and less likely to damage floors. Let’s break down the different types of finishes and coatings you’ll encounter:
Bare Iron / Steel Weight Plate
Bare plates are the most affordable option, made from iron or steel without any coating. They are noisy, prone to rust, and can damage your floors when dropped. The problem is that iron plates from lower-quality brands may have weight inaccuracies of 5 to 10%
Pros:
- Low cost
- Good grip
Cons:
- Noisy
- Prone to corrosion
- May damage the floor
- Possible weight deviations
Chrome Weight Plate
Chrome-plated plates are more durable than bare plates and offer a sleek, shiny finish. They are resistant to rust and are often used for their visual appeal. These plates are typically more long-lasting than uncoated steel or iron, and some rubber or urethane-coated plates also feature a chrome layer for extra durability.
Pros:
- Glossy, polished finish
- Affordable
- More durable than bare plates
- Often used in rubber or urethane-coated forms
Cons:
- Can still be scratched
- Can get slippery
Rubber-coated Weight Plate
Rubber-coated plates are a popular choice in gyms because they are durable and help protect both the plate and your floor. These plates also known as ‘Non-standard Olympic plates’ are made of steel or iron with a rubber coating, making them longer-lasting than bare plates. However, the rubber can get scratched easily, and cheaper plates may emit a strong smell.
Pros:
- Affordable
- Protects equipment and floors
- Long-lasting
Cons:
- Rubber smell
- Prone to scratches
Urethane Coated Weight Plate
Urethane-coated weight plates are the most durable option and highly resistant to scratches but come at a higher cost. They provide excellent protection for gym equipment and floors while maintaining a smooth, odorless finish. These plates are thinner than rubber-coated ones, allowing more weight to be loaded on a bar. If you’re looking for a long-lasting, premium choice, urethane plates are worth the investment.
Pros:
- Extremely durable
- Scratch-resistant
- Odorless
- Thinner, allowing more plates on a bar
Cons:
- Expensive
- Heavier upfront investment
3. Weight Plate Physical Structure
The physical structure of a weight plate affects its usability, grip, and overall functionality in the gym. By understanding key structural features, you can make better decisions on which plates will work best for your space. Here are the important elements to look for in weight plates:
Plate Material
The material of a weight plate is a strong indicator of its quality. Steel plates are generally more durable and accurate than cast iron plates. Weight plates areprojected to grow at a CAGR of 4.3% as per Adroit Market Research. This growth highlights the importance of steel plates for long-term use, especially in commercial settings.
Handle/Grip
Weight plates with built-in handles or grips are easier to manage, especially with heavier plates. While lighter plates (up to 10 lbs) can be handled without grips, plates weighing 35 lbs or more are much easier to load if they have a handle. And the best part is that gripped plates can also be used in a variety of exercises, such as shrugs or carries, where the plate itself acts as the weight.
Bevel / Lip
A bevel or lip is a small indentation around the outer edge of the plate. This makes it easier to pick the plate up off the ground and separate it from other plates on the bar. Without a bevel, it may hard to lift plates, especially when they are stacked together or lying flat on the ground. This small feature is often overlooked but can make a big difference in day-to-day use.
Weight Plate Thickness
The thickness of a weight plate impacts how many plates can be loaded onto a barbell. Thinner plates, like those made of urethane or calibrated steel, allow for more weight to be added to the bar. Thicker plates, especially rubber-coated ones, take up more space and limit how much weight it can stack.
Weight Plate Diameter
Most standard Olympic plates have a consistent diameter of 450 mm, especially bumper and urethane plates. However, some iron plates can vary in size depending on their weight. Consistent diameter plates help maintain barbell balance and allow for safer lifting, particularly for Olympic lifts and deadlifts.
4. Weight Plate Physical Properties
The physical properties of weight plates can greatly impact their performance and safety during workouts. Understanding these key features will help you select the right plates for your gym. Here are the important properties:
Shape
While most weight plates are round, you may come across plates with 8 or 12 sides. These multi-sided plates were once popular in high-end gyms but have fallen out of favor due to safety concerns. Flat-sided plates can shift during lifts that start or end on the floor, which increases the risk of injury. Round plates from YR Fitness are much safer and are the preferred option for most gyms.
Size
The size of weight plates, especially the hole diameter, plays a crucial role in their compatibility with different types of gym equipment. Below are the main types of weight plate sizes and their typical uses:
- Olympic Size Plates (2 Inch Hole): Olympic plates have a 2-inch hole and are the most widely used in commercial gyms. These plates fit all standard Olympic bars and are ideal for powerlifting, bodybuilding, and general fitness.
- Standard Size Plates (1 Inch Hole): Standard plates have a smaller 1-inch hole and cannot be used with Olympic bars. They are more commonly found in home gyms and are suitable for beginners or those with simpler weightlifting needs.
- Studio Size Plates (30 mm Hole): Studio plates, with a 30 mm hole, are typically used in group fitness classes like body pumps. The cool thing is that they are lightweight, rubber-coated, and often have handles for easy use during high-rep exercises in a studio setting.
Thickness
The thickness of a weight plate impacts how it behaves when dropped. Thicker plates, such as bumper plates, are safer for protecting floors but take up more space on the bar, limiting how much weight you can load. Bumper plates are ideal for functional training and home gyms, while thinner Olympic plates are better suited for powerlifting and commercial gyms where higher weights are needed.
Weight Tolerance
Weight plates may not always match their stated weight due to manufacturing variations. While manufacturers aim for accuracy, metal differences can cause discrepancies. For serious lifters, precise weight is crucial. Here are key tolerance guidelines for weight plates:
- 2% Tolerance: With 45 lb weight is recommended for competition training, providing minimal variation from the labeled weight for precision and safety.
- 4% Tolerance: Generally acceptable for general strength training, allowing for practical flexibility while maintaining reasonable accuracy.
Durability
If you want a set of weight plates that will last for decades, it’s best to avoid cheap options. Urethane-coated plates from YR Fitness are ideal for long-term use, as they maintain their condition even after years of heavy use. While cast iron weight plates, rarely break, plates with grips can sometimes crack if dropped. Urethane-coated plates are more resistant to this type of damage, a reliable and durable choice.
5. Weight Plate Accessories
When setting up a gym, weight plates aren’t the only things you’ll need. Several accessories can improve the safety, efficiency, and organization of your gym equipment. Here are the accessories you should consider adding:
- Barbell Collars: Barbell collars are essential for securing weight plates on the bar during lifts. Collars are easy to use and come in various styles like spring clamps or lock-jaw designs.
- Weight Plate Rack: A weight plate rack helps keep your gym organized by providing a designated space for plates. It makes it easy to store and access plates while also reducing clutter in the workout area.
- Barbell Pad: A barbell pad is a cushion that wraps around the barbell, offering extra comfort and protection during exercises like squats. And you know what? It reduces pressure on the shoulders and neck, making it easier to perform heavy lifts.
- Deadlift Jack: A deadlift jack is used to lift 1 side of the barbell off the ground, making it easier to load or unload weight plates. This saves time and effort, especially when dealing with heavy weights.
- Bumper Plate Stands: Bumper plate stands are specially designed to hold thicker bumper plates. They help keep these plates organized and easy to access during workouts.
- Fractional Plates: Fractional plates are smaller weight plates that allow for gradual increases in weight. They come in weights as light as 0.25 lbs and are a great way to push beyond levels.
6. 5 Buying Tips and Traps to Avoid
When selecting gym weight plates, it’s crucial to balance high-quality options with more affordable alternatives. To help you make the best decision, here are some key tips to keep in mind:
- Check Bar and Plate Compatibility: Make sure the plates you purchase are compatible with the barbells you use. For example, Olympic plates with 2-inch holes fit standard Olympic bars. Avoid plates with oversized holes, as they can cause instability and safety risks during use.
- Check Bar’s Sleeve Diameter: It’s important to know the diameter of the barbell’s sleeve before purchasing weight plates, especially for non-Olympic bars. Here’s what I mean, mismatched sizes can lead to improper loading and decreased safety.
- Avoid Oversized Holes: Plates with holes larger than the bar’s diameter can create an unstable lifting experience. This instability increases the risk of the plates slipping off during workouts, which is both inefficient and unsafe.
- Plates with Handles: These handles make heavy plates easier to load and unload, improving both efficiency and safety in your gym. For instance, smooth plates without handles can slow down the process and lead to more manual handling issues.
- Raised Inserts: Weight plates with raised inserts or a beveled edge offer greater ease of use. They prevent the plates from sitting flat on the floor, allowing them to slide the fingers underneath for quick and easy lifting.
Conclusion
Selecting the right weight plates for your gym is an important decision that impacts safety and performance. With so many options available, it’s important to know what materials and features best suit your needs. With the right knowledge, you can now confidently invest in the best plates for your gym.
