Don't Be Fooled by Specs! Understand the "Core Three Elements" of Sports Wood Flooring and Choose Wisely – No Hidden Fees
Hello, we are Mindu Sports Wood Flooring Manufacturer. Today, we want to discuss practical matters and help you transform those seemingly complex technical parameters into useful tools for smart purchasing.
Specs are the "health report" of the flooring; if you can't understand them, you risk being misled.
Many salespeople will simply tell you, "Our floor is good," but good in what way? They can't elaborate. Professional manufacturers, however, dare to speak with data. By understanding the three core parameters below, you can instantly upgrade from a "newbie" to a "connoisseur."
> Core Element One: Shock Absorption ≥53% – The "Invisible Insurance" for Your Knees and Ankles
What is it? Simply put, it’s the percentage of impact force the floor can "absorb" when you jump and land. For example, if your knee bears 1000 Newtons of force upon landing, a good floor can absorb over 530 Newtons, meaning the actual force exerted on your body is less than 470 Newtons.
Why is this data so crucial? Both the International Basketball Federation (FIBA), the NBA, and China's National Standard (GB/T 20239-2015) explicitly mandate that the shock absorption rate for professional basketball flooring must be no less than 53%.
Our Professional Take: This index is directly linked to the risk of sports injuries. A value that is too low means the floor is as hard as concrete, and long-term training places an immense burden on an athlete's knees, ankles, and lumbar spine. Our Flooring, through a unique "double-layer subfloor system" and high-performance resilient pads, consistently controls the shock absorption rate within the 55%-60% golden range. This provides adequate protection while preventing the fatigue associated with excessively soft surfaces.
> Core Element Two: Ball Rebound ≥90% – Determining the Ball's "Obedience"
What is it? This index measures how high a basketball will bounce back after hitting the floor. The standard test involves dropping a basketball from a height of 1.8 meters and measuring the rebound height. The National Standard (GB/T 20239-2015) requires a Ball Rebound rate of ≥90%.
Its impact on the sports experience: If the rebound rate is insufficient, the basketball will feel "flat," making dribbling and passing weak. This seriously affects the pace of the game and the athletes' performance. A stable, high-rebound surface is fundamental to ensuring the accuracy of technical movements.
Our Professional Practice: Our carefully selected North American Maple A-grade panels, combined with precise surface fixing technology, ensure uniform force distribution, achieving a Ball Rebound rate of ≥93%. This means every bounce provides solid, predictable feedback, keeping the ball fully under control.
> Core Element Three: Vertical Deformation W500≥2.3 mm – The "Airbag" Under Your Feet
This parameter is the most easily misunderstood, yet it is critically important. It simulates the floor's indentation when a force of 500 Newtons (approx. 50kg) is applied to a single point of support. The National Standard requires this value to be ≥2.3mm.
Our Unique View: This deformation is not a flaw, but an intelligent feature! Many people mistakenly believe the floor should be completely rigid. A reasonable amount of depression is precisely the floor's cushioning system at work, effectively absorbing energy, much like a car's airbag. However, the deformation must be controlled! The National Standard also specifies "Concentrated Load" deformation requirements under a 1500 Newton force. Together, these standards ensure that while the floor is locally resilient, the overall structure remains rock-solid, eliminating the risk of lateral tipping.
Our Technical Guarantee: Our products are designed and verified through computer simulation and physical testing to ensure the Vertical Deformation value is stably controlled between 2.5 mm - 3.0mm, perfectly meeting and surpassing the national standard. This provides a comfortable underfoot feel without sacrificing overall stability.
Professional sports wood flooring is a complex systematic project, not just a simple拼（a simple splicing） of wooden planks. The next time you communicate with a supplier, be sure to ask directly:
"What is the specific test data for your floor's shock absorption rate? Can you provide the testing report?"
"What kind of subfloor system do you use? How do you guarantee all three core indices meet the standards simultaneously?"
A manufacturer who dares to answer these questions head-on and in detail is a partner with genuine professional expertise and integrity. At Mindu Flooring, we always have third-party authorized testing reports ready; you are welcome to request and verify them at any time.
