Which is safer, the glass back panel or the tempered panel of the basketball stand?

Tempered glass back panels are safer than ordinary glass back panels for the following reasons:

1. Safety Advantages of Tempered Glass Back Panels

Safe Fragment Form

Tempered glass is a safety glass that uses chemical or physical methods to create a compressive stress layer on its surface. When damaged by external forces, the fragments break into a honeycomb pattern of small, blunt-angled particles rather than sharp fragments, significantly reducing the risk of scratches. For example, tests at a middle school showed that basketball hoops using 12mm thick tempered glass backboards showed no cracks on the backboard surface after five years of frequent use, and the light transmittance decreased by only 3%, far superior to traditional glass.

Strong Impact Resistance

Tempered glass has an impact resistance 3-5 times that of ordinary glass, and its bending strength is also 3-5 times greater. For example, 12mm thick tempered glass can withstand the impact of a 500g steel ball dropped from a height of 1.5 meters, while ordinary glass would easily shatter under the same conditions. This characteristic allows it to withstand high-frequency impacts such as students' powerful dunks and high-speed basketball impacts, reducing the risk of breakage. High Thermal Stability

Tempered glass can withstand temperature fluctuations three times greater than ordinary glass, and can withstand temperature swings of up to 300°C. This characteristic makes it less susceptible to cracking due to sudden temperature changes in outdoor environments, making it suitable for use in diverse climates.

Second, Safety Hazards of Ordinary Glass Back Panels

Sharp Shards Can Injure People

Ordinary glass breaks into sharp fragments that can injure users. For example, if the back panel of a basketball hoop is made of ordinary glass, the fragments could cause severe cuts if the glass breaks while a student is dunking.

Weak Impact Resistance

Ordinary glass has low impact strength and is easily broken by impacts from basketballs or external forces. For example, 5mm thick ordinary glass may crack or even shatter when struck by a basketball traveling at 8m/s, whereas tempered glass only undergoes slight elastic deformation and recovers instantly.

Poor Thermal Stability

Ordinary glass is prone to cracking due to sudden temperature changes. For example, the back panel of an outdoor basketball hoop in winter can become brittle due to low temperatures. Heat can cause sudden expansion and cracking, increasing safety risks. Other Advantages of Tempered Glass Backpanels

High Transparency Enhances the Viewing Experience

Tempered glass has a light transmittance of ≥92%, making it highly transparent and enabling spectators to clearly observe the basketball shots. For example, school playground basketball hoops utilize 12mm thick tempered glass backboards, offering excellent light transmittance and a near-professional playing experience.

High Durability Reduces Maintenance Costs

Tempered glass backpanels offer a long service life, with no noticeable surface wear after prolonged use. For example, after five years of use, a middle school basketball hoop saw only a 3% decrease in light transmittance, reducing annual maintenance costs by 70%, significantly outperforming traditional glass backpanels.

Moderate Elasticity Adapts to the Laws of Motion

The moderate elasticity of tempered glass backpanels ensures a more realistic rebound effect after a shot, enhancing training effectiveness. For example, a home basketball hoop with a tempered glass backpanel allows children to experience a realistic rebound when shooting, fostering their interest in the sport.
