Material and protective performance High strength composite material Wooden frame: The frame is made of sturdy wood to provide stable support and give the product a natural and beautiful texture. UV protection PC panel: High light transmittance (≥ 90%), able to clearly display the details of the collection, while effectively blocking 99% of ultraviolet rays to prevent the jersey from fading due to light exposure. The impact resistance is 250 times that of ordinary glass, not easily broken, and suitable for long-term use. Strong weather resistance, able to maintain stable performance in environments ranging from -20 ℃ to+60 ℃, avoiding deformation caused by temperature changes. Internal structure strengthening Fiberboard backboard: moisture-proof, insect proof, ensures stable internal environment, and extends the shelf life of collections. Metal reinforcement: Metal hardware is used at critical connections to enhance overall structural stability, with a load-bearing capacity of up to 15kg.
