Architecture, Building and Structure Design Union Industrial Corporate Building by POPCHING CONSTRUCTION CO., LTD Union Industrial is a corporate headquarters building designed for a company that produces electronic components. The exterior is covered by a curtain wall of stainless steel perforated plates, which recall printed circuit board imagery and the corporate logo. The metal curtain shades the interior, while people inside can still sense outside light and weather. Three layers of fluorocarbon baking paint give the plates a bright and weather-resistant finish. A central patio brings sunlight to every floor. The entrance rain shed carries a scannable code and solar panels.
