The materials for bus shelters are diverse, but when clients are planning the materials for their bus shelter projects, asWaiting Shelter ManufacturerWhy does Wancheng Smart strongly advise against using polycarbonate panels as the roofing material for bus shelters? Just take a look at the following image and you'll understand.
From the second half of 2020 to September 18, 2021, steel prices have been on the rise. According to information from Wan Cheng suppliers, the current price for galvanized steel plate, the main material for bus shelters, is 6,300 yuan per ton. Nevertheless, it is still not recommended to use the cheaper polycarbonate panels as the roofing material.
Polycarbonate sheets, essentially a type of plastic, are available in popular colors such as blue, green, and tan, and were initially used inWaiting ShelterTo reduce the ceiling weight, enhance the texture of the material, and personalize the waiting shelters, while also considering the project cost, using polycarbonate panels can save on the cost of steel used in the shelters and surface treatment costs.
However, the use of polycarbonate panels outweighs the disadvantages. Firstly, the roof serves as a protective layer, especially during severe weather conditions such as heavy rain, hail, and snow. It is essential to protect passengers from such hazards. It is understandable that, due to the plastic nature of the polycarbonate, which is lacking in tensile strength and soft in texture, accidents of penetration and collapse are inevitable! Secondly, the panels fail to provide adequate shading, sealing, and waterproofing due to their material properties. Under prolonged exposure to intense sunlight or heavy snow, they can渗透、deteriorate, and shrink in volume, leading to deformation.
As depicted in the photos within this article, this waiting shelter has withstood the elements for six years. The sunshade panels in the roof have been infiltrated with a large amount of wastewater and moss, and there are also signs of the ceiling sagging and bulging between the two joists. Not only does this hinder safe travel, but it also tarnishes the city's image.
