Bumper plates are a crucial component of any modern gym. Selecting the right bumper plates for your members requires thorough research and insider knowledge. This article provides you with the essential information to make informed bumper plate purchasing decisions.
Understanding Bumper Plates
Differences between Bumper Plates and Weight Plates
Bumper plates and weight plates differ in several key aspects. Bumper plates are designed to be dropped from a height without damaging the floor or the plates themselves. They are typically made from dense rubber, making them more durable and safer for high-impact lifts.
Types of Bumper Plates to Buy
Choosing the right type of bumper plate depends on your gym's needs and your members' preferences.
Training Bumper Plates
Training bumper plates are consistent in diameter but vary in thickness according to weight. They adhere to International Weightlifting Federation (IWF) standards and are designed to withstand the impact of heavy lifts. These plates are common in commercial gyms and are suitable for most lifting activities.
Competition Bumper Plates
Competition bumper plates meet IWF specifications for size, tolerance, and color. They feature a solid steel core embedded in rubber, making them thinner and more loadable on a barbell. These plates are ideal for serious athletes and competitive lifters.
Technique Plates
Technique plates are lightweight and made of solid plastics. They are ideal for beginners to practice lifting techniques without heavy weight. Available in increments of 5 lb, 10 lb (2.5 kg, 3.75 kg, and 5 kg), these plates are also useful for rehabilitation training.
Change Plates and Fractional Plates
Change plates and fractional plates are used for making small weight adjustments. Change plates range from 0.5 kg to 5 kg (or 1.25 lb to 10 lb), while fractional plates allow for micro-loads ranging from 0.125 kg to 1 kg (or 0.25 lb to 1 lb).
Materials of Bumper Plates
Virgin Rubber
Virgin rubber plates are dense, durable, and have minimal bounce. Made from pure rubber, they offer a smooth and odor-free experience, making them ideal for high-traffic gyms.
Crumb/Recycled Rubber
Crumb rubber plates are made from recycled tires. They are softer, have more bounce, and are less durable than virgin rubber plates. However, they are cost-effective and environmentally friendly.
Urethane
Urethane plates combine the best properties of plastics and rubber. They are extremely durable, have low bounce, and are odorless. Although more expensive, urethane plates are ideal for those who prioritize aesthetics and durability.
Structure and Properties of Bumper Plates
Plate Structure
The quality of a bumper plate is largely determined by its material. Urethane is the best overall, followed by virgin rubber, and then recycled rubber.
Steel Hub
The steel hub ensures durability and proper fit on the barbell. Modern plates use stainless steel hubs, which are superior to the outdated brass hubs. A well-designed steel hub should fit easily into the sleeve of the bar, ensuring a secure fit and easy handling.
Physical Properties
Shape
All weight plates should be perfectly round with a lip on the edge for easy handling and to protect the steel hub. A round shape ensures stability and ease of use during lifts.
Weight
Bumper plates are available in kilograms and pounds, adhering to IWF standards with a weight tolerance typically within 2-3%. Accurate weight ensures consistent performance and safety during lifts.
Color
Bumper plates are color-coded according to IWF standards for easy identification. Color coding helps lifters quickly select the right weight, enhancing the efficiency of workouts.
Noise
Rubber and urethane materials absorb impact, reducing noise compared to steel plates. This makes bumper plates ideal for environments where noise reduction is important.
Odors
Virgin rubber has a mild odor, recycled rubber has a stronger smell, and urethane plates are odorless. Odorless plates are preferable for indoor environments where air quality is a concern.
Bounce and Hardness
Bumper plates should aim for minimal bounce, achieved through high Shore hardness ratings. Competition plates offer the best balance of low bounce and durability, ensuring safety and performance.
Bend
High-quality materials prevent bending, which is crucial for maintaining an even load. Plates that bend can cause instability and increase the risk of injury.
Buying Tips and Traps to Avoid
Material Quality
Ensure the material is pure and not mixed with inferior substances. High-quality materials ensure durability and performance.
Weight Accuracy
Look for plates with a low weight variance. Accurate weight is essential for consistent performance and safety.
Warranty
A good bumper plate should come with at least a one-year warranty. A warranty provides assurance of the plate's quality and durability.
Dimensions
Plates should adhere closely to IWF standards. Proper dimensions ensure compatibility with standard equipment and optimal performance.
Color Coding
Ensure accurate color coding and even coloring. Proper color coding helps with quick weight selection and maintains a professional appearance.
Lettering
Opt for raised lettering over printed words for longevity. Raised lettering remains legible over time, ensuring ease of use.
Steel Hub
Prefer steel or stainless steel hubs over brass. A high-quality steel hub enhances durability and performance.
Drop Test
Check manufacturer data for durability under repeated drops. A reliable drop test indicates the plate's ability to withstand regular use.
