拱形屋顶彩涂板的特点有哪些

应用行业：拱形屋顶，主要用于体育场馆、交易市场、展览馆、仓储物流
其建筑特点是无拱、无梁、无投资、无场地、无物流等特点。由于拱顶结构无梁、无檩条，空间跨度大，对彩涂板的强度要求较高

选材标准：根据拱顶跨度大小，底板建议选用屈服强度280-550mpa的高强度彩钢板，其牌号为：ts280gd+z-ts550gd+z，底板双面涂膜不小于120g/m2，涂层结构一般为两层两烘，前涂层厚度不小于20μm，后涂层厚度不小于10μm，根据使用环境和工程造价，可采用PVDF氟碳、SRP特种增强聚酯、HDP高耐候或普通PE聚酯习惯于

Application Industry: arched roof, mainly used in stadiums, trading markets, exhibition halls, warehousing and logistics

Industry characteristics: the arched roof is widely used in stadiums, trading markets, exhibition halls, warehousing and logistics due to its characteristics of no beam and no purlin, wide space, large span, low cost, less investment, short construction period and economic benefits. Due to the construction structure without beam and purlin and large space span, the arch roof has higher requirements for the strength of color coated plate
Material selection standard: according to the span size of arched roof, it is recommended to select high-strength color plate with yield strength of 280-550mpa for the base plate, and its brand is: ts280gd + z-ts550gd + Z. the double-sided coating of the base plate shall not be less than 120g / m2, and the coating structure shall be generally two-layer coating and two baking, with the front coating thickness no less than 20 μ m and the back coating no less than 10 μ M, According to the application environment and project cost, PVDF fluorocarbon, SRP special strengthened polyester, HDP high weather resistant or ordinary PE polyester can be used
