南画廊由原化工研究所锅炉房改造而成,其覆面采用的是普通的石棉瓦,画廊主入口采用了更为触目的耐候钢板门。大门分为3扇,耐候钢板边框垂直于墙面形成筒型入口。筒型耐候钢板入口锈蚀的速度远高于石棉瓦接缝的锈渍蔓延速度。几个月后,这个建筑就像存在了几十年,自此外表面的蜕化逐渐稳定下来。可以这样说,整个外皮传达出的是一种时间后缩 The South Gallery, formerly known as the Institute of Chemical Industry, has been transformed from a boiler room with a common asbestos tile. The gallery entrance uses a more striking weathering steel door. The door is divided into three, weathering steel frame perpendicular to the wall to form a cylindrical inlet. Barrel weathering steel entrance corrosion rate is much higher than the asbestos joints rust spread speed. A few months later, the building was there for decades, and the degeneration of the outer surface gradually stabilized. It can be said that the whole skin conveys a kind of time shrinkage
