The specified light-transmitting panels exhibit exceptional sound-absorbing properties under the influence of external noises such as heavy rain and strong winds. The impact-resistant light-transmitting panels possess robust impact resistance. Test results indicate that a 1kg steel ball dropped from a height of 3 meters will not crack, and their impact resistance under low temperatures is also notably significant.

Next, the useful width of the composite roof tiles is 880mm, which is more practical and economical than 960mm. For the planning, please refer to "Flat to Slope Building Structures". Each square meter of tiles requires 4-6 sets of special screws. The green lighting panels are free of asbestos and radioactive elements, are recyclable, and fully comply with environmental protection standards.
