When selecting a floor spring, the primary consideration is the weight of the door, which determines the appropriate model for optimal performance. The weight of glass can be calculated using national standards. For instance, 1 mm-thick ordinary or tempered glass weighs approximately 2.5 kg per square meter. In China, a common glass door might measure 2.2 meters in height and 1 meter in width with a thickness of 12 mm. Based on these dimensions, the weight of this glass door would be roughly (2.2 x 1) x (12 x 2.5) = 66 kg.
To determine the total weight of the door, you must add the weight of all associated hardware and accessories to the glass's weight. Using a floor spring that is underloaded for the door’s weight not only drives up the cost of manufacturing the door itself but can also lead to suboptimal functionality due to excessive weight. On the other hand, opting for a floor spring with insufficient load-bearing capacity to cut costs may seem economical initially, but it can significantly impact the lifespan of the spring. Overloading or underloading a floor spring compromises its ability to function properly, leading to premature wear and tear. Therefore, it's essential to strike the right balance when choosing a floor spring that matches the door's weight specifications to ensure both efficiency and longevity.
