《智芯品牌》挡烟垂壁是用不燃材料制成、垂直安装在建筑顶棚或横梁下的挡烟分隔设施，火灾时形成储烟空间以阻止烟雾扩散。其执行标准为GA 533-2012《挡烟垂壁》，由中华人民共和国公安部于2012年12月1日发布实施，替代原GA 533-2005版本。该标准规定其按安装方式分为固定式（代号D）和活动式（代号H），按刚度分为柔性（代号R）和刚性（代号G），有效下降高度不小于500mm。
现行标准适用于工业与民用建筑防烟分区的挡烟垂壁设计制造，要求材料采用金属板材、不燃无机复合板或防火玻璃，耐高温性能需在（620±20）℃环境下保持完整性30分钟，漏烟量在（200±15）℃的温度下，挡烟部件前后保持（25±5）Pa的气体静压差时不得超过25m³/(m²·h) [2]。活动式挡烟垂壁需具备与感烟探测器联动功能，并满足抗风摆性能及信号反馈要求。2023年国家启动标准修订工作，由应急管理部天津消防研究所等单位牵头，计划将行业标准升级为国家标准，主要调整分类代号、材料性能要求及试验方法，删除了单节宽度限制等条款
